The importance of vitamin D in supporting the immune system

Researchers from The Irish Longitudinal Study on Ageing (TILDA) have released a crucial report which shines a light on the role of vitamin D and unveils shocking levels of deficiency in older people in Ireland. The team, based at Trinity College in Dublin, concluded that Vitamin D supplementation was necessary for those over the age of 50 and those currently shielding. They also highlighted a range of studies showing vitamin D plays a role in the prevention of respiratory infections, boosting the immune system response to infections and reducing the need for antibiotic use. 

The study, titled Vitamin D deficiency in Ireland – implications for COVID-19, used data from wave 1 of The Irish Longitudinal Study on Ageing (TILDA), which started back in 2009. This was a prospective study of 8,172 adults aged 50 years and older in Ireland living in the community – not in care homes or hospitals. The participants were personally interviewed and their answers on their socio-demographic status, physical, mental and behavioural health recorded. 72% of the participants consented to a health assessment and of those, 91% submitted a blood sample for vitamin D level assessment (5,382 people). 

The data revealed that of those aged 55+ years in the Republic of Ireland, 1 in 5 are vitamin D deficient during the winter and 1 in 12 during the summer. This rises to nearly 30% of those aged 70+ and 47% of those aged 85+. These are the age groups considered to be ‘extremely medically vulnerable’ to adverse health outcomes of COVID-19 and have been advised to participate in ‘cocooning’ (known as ‘shielding’ in the UK) during the pandemic.

The researchers also considered the findings of a range of medical studies into the role of Vitamin D in immune function and immune response to infection. One such study in 2017 carried out by Vanherwegen AS, Gysemans C, Mathieu looked at regulation of immune function by vitamin D and its use in diseases of immunity.

Principal Investigator of TILDA Rose Anne Kenny comments:

“We have evidence to support a role for Vitamin D in the prevention of chest infections, particularly in older adults who have low levels. In one study Vitamin D reduced the risk of chest infections to half in people who took supplements. Though we do not know specifically of the role of Vitamin D in COVID infections, given its wider implications for improving immune responses and clear evidence for bone and muscle health, those cocooning and other at-risk cohorts should ensure they have an adequate intake of Vitamin D.”

The researchers concluded that adults aged over 50 should take Vitamin D supplements, and not just in winter, but all year round if they don’t get enough sun.

Can Vitamin D help you right now?

As governments around the world battle the COVID-19 pandemic, public health measures that can reduce the risk of infection and death in addition to lockdowns and social distancing are desperately needed. Here at Altruvita we’re constantly reading about the latest clinical trials and studies looking at the impact of micronutrients, nutrition and vitamin deficiencies on health.

An article published by a team based in the US and Hungary reviewed the roles of vitamin D in reducing the risk of respiratory tract infections, knowledge about the epidemiology of influenza and COVID-19 and how vitamin D supplementation might be a useful measure to reduce risk. 

Vitamin D is already known to reduce risk of infections through several mechanisms. Those mechanisms include lowering viral replication rates and reducing concentrations of pro-inflammatory chemicals that produce the inflammation that injures the lining of the lungs, leading to pneumonia.

Evidence supporting the role of vitamin D blood levels in reducing risk of COVID-19 infection includes that fact that the outbreak occurred in winter, a time when vitamin D concentrations are lowest. Note that the number of cases now in the southern hemisphere near the end of their summer are low (for example in Australia, New Zealand and South Africa). Cases have been higher than in areas which are most likely to have vitamin D deficiency.

Vitamin D deficiency has been found to contribute to acute respiratory distress syndrome (ARDS); and that case-fatality rates increase with age and with chronic disease comorbidity, both of which are associated with lower 25(OH)D concentration. 

According to national surveys in the UK, across the population approximately 1 in 5 people are thought to have low vitamin D levels and are deficient (defined as serum levels below 25 nmol/L). Patients with levels 25 nmol/L to 50 nmol/L are classed as insufficient.

The UK has been lucky to enjoy sunny weather since the start of the lockdown, an end to the heavy rain of the winter just gone. Those of us who are lucky enough to be able to get out in our gardens or take a daily walk outside are now getting an opportunity to soak up some sunshine. Between late March/early April and September, the majority of people aged 5 years and above will probably obtain sufficient vitamin D from sunlight when they are outdoors, alongside foods that naturally contain or are fortified with vitamin D.

However, the authors of the review suggest that the goal should be to raise 25(OH)D concentrations above 100-150 nmol/L, which is way higher than just obtaining sufficient levels (anything over 50 nmol/L). The only way to achieve this fast enough during the peak of the this pandemic is to do everything – get out in the sun, eat vitamin D rich foods and take a supplement.

Some studies have reported that vitamin D supplementation reduced the risk of influenza, whereas others studies did not. To reduce the risk of infection, the authors of this paper advised that people at risk of influenza and/or COVID-19 consider taking 10,000 IU/d of vitamin D3 for a few weeks to rapidly raise 25(OH)D concentrations, followed by 5000 IU/d. For treatment of people who become infected with COVID-19, higher vitamin D3 doses might be useful. Randomised controlled trials and large population studies should be conducted to evaluate these recommendations.

How to support your immune system

There has never been a more important time to be proactive with our nutrition, with the aim of supporting the very best immune system defence.

Our immune systems play a role not only in fighting off infections, but also in promoting tissue repair to recovery. To function properly, our immune system requires plenty of both macro and micronutrients.

To help support your health over the next few months, we’ve put together a few diet and lifestyle pointers to keep you going in this worrying time.

Avoid strenuous exercise

Moderate-intensity exercise can be protective against illness by boosting the immune system, whereas high-intensity sessions actually compromise the immune system. Our immune system takes a hit for up to 72 hours following high-intensity training, making this a key time for susceptibility. This is especially important to note if you exercise in a class with others, where you’re more likely to pick up bacteria and viruses.

Let yourself sleep, rest and recover

Rest and recovery are key to prevent getting ill and further unwanted illness. If you’re always on the go with minimal rest, your immune system can be compromised long term. Poor sleep can affect the immune system and make you more susceptible to infection or illness. Sometimes it’s hard to stop, particularly when the future feels so uncertain, but don’t ever underestimate the importance of rest and relaxation! Run a hot bath, read a book, get a massage or listen to relaxing music every now and again.

Don’t drink excessive amounts of alcohol

Excessive chronic intake of alcohol can decrease the number of a few white blood cells types, which means that your immune system will not be as able to fight off any bugs. Keeping within the alcohol guidelines will help, which in the UK is currently set at 14 units per week. That’s 6 pints of beer or 6 glasses of wine if that’s your preferred tipple. If you do prefer to round off the week with a few drinks you could pick drinks with healthy, vitamin-packed mixers such as orange, tomato or pineapple juice.

It’s not the time to diet

If you are unlucky enough to pick up an infection, you will need plenty of energy to fight it off. That means that it might not be the wisest time to start a calorie reduced diet – unless of course you have a pressing health issue that means you need to lose weight urgently. Low intakes of carbohydrates such as bread, rice and potatoes, which end up as glucose in the blood, can be a contributing factor to impaired immunity.

Keep well hydrated

Unfortunately, being dehydrated can also contribute to a compromised immune system. Still at this time of year when there’s still a bit of a nip on the air, it’s easy to forget to drink. One of the front-line defences in our immune systems are the immune proteins in our saliva. When we’re dehydrated, the levels of these proteins decreases, meaning our initial defence to bugs entering through the mouth is also decreased. Make sure you don’t wait to feel thirsty before you drink up, carry a water bottle with you (everywhere!) and keep sipping throughout the day.

Taste the Rainbow

Fruit and vegetables contain a wide range of different micronutrients with varying roles within the body. Many of these nutrients are involved in immune function such as iron, vitamins C and D, selenium and zinc. Anyone with even mild deficiencies in any of these micronutrients can have an altered immune response.

The easiest way to ensure you’re getting enough micronutrients and other phytochemicals is to consume a wide variety of different fruit and vegetables. Taste the rainbow- choose different coloured and textured fruit and veg every single day!

Vitamin Supplements

Vitamin C, vitamin D and selenium all help to support a healthy immune system. Not everyone can eat enough to get these micronutrients (or get enough sun in a UK winter), so consider taking a food supplement if you are lacking some antioxidant or immune protection. Contrary to popular belief, huge doses of vitamin C are not required in winter. At doses of say 400-500mg a day, the excess vitamin C is simply excreted in urine, making it literally money down the toilet!

In summary: consume enough antioxidants to support your immune system, sleep well, drink plenty (but not too many drinks of the alcoholic kind), avoid strenuous activity and wash your hands before eating to stay well.

Answering the 3 most common vegan nutrition questions

Both in the UK and across the Western world veganism is rapidly growing in popularity.  The number of people who signed up to take part in ‘veganuary’ between from 2014 to this January is an excellent demonstration of just how quickly dipping a toe in veganism is gaining in popularity:

2014 – 3,300

2015 – 12,800

2016 – 23,000

2017 – 59,500

2018 – 168,500

2019 – 250,000

2020 – 400,000

Even if you’re only trying out veganism for a short time, it’s still important to ensure you are getting a balanced diet. We sat down with Altruvita’s nutrition team to talk about the 3 questions about vegan nutrition that they get asked most often and make sure you have all the answers you need.

Can I get enough protein in my diet if I am a vegan?

Of the eight essential amino acids our body needs, two – lysine and methionine – are given special attention in vegetarian and vegan diets. This is because, compared with foods of animal origin like eggs, milk and cheese, various plants have an imbalance of either lysine or methionine. This includes cereals, such as wheat, oats and rice, and legumes; beans, peas and lentils.  Wheat and rice proteins are comparatively low in lysine but better sources of methionine whereas beans and peas are relatively high in lysine yet in lower methionine. This has naturally led to the idea of cereals and legumes as ‘complementary’ proteins. In practice this means that meals that combine for example rice with beans or hummus with bread will provide a biologically ‘complete’ protein intake.   

As the body does not readily store amino acids try to combine ‘complementary proteins’ at each meal as it has some advantages and seems a sensible way to approach a varied and complete diet. It doesn’t matter if you can’t do this for every single meal you consume, however.

I’ve heard vitamin B12 is important – how do I ensure I’m getting enough B12? 

Vitamin B12 plays an important role in brain and heart health, nerve cells and red blood cell function. The most bioavailable form of B12 is unique to animal sources, with top sources including shellfish, lamb and beef. You may have good bodily stores of B12 when you begin a vegan diet which can keep you going for several months before they drop, and you start to notice symptoms like tiredness, brain fog, and poor memory. Vegans need to ensure they are consuming reliable sources of vitamin B-12, such as fortified foods or B12 supplements to keep adequate body stores and blood levels. 

Beware! Spirulina and other edible cyanobacteria (commonly called blue-green algae) contain a poorly bioavailable B12 which isn’t converted to B12 in humans.  We can’t absorb it, so consider using a B12 supplement if you plan to be wholly plant-based for more than a few months.

Can my dog become vegan too?

Dogs, like most canines, are naturally omnivores which means they eat both meat and plant-based foods. Some people who choose a vegan diet want to feed their pet one too. The reasons for feeding your dog a vegan diet might include the welfare of farmed animals being killed to feed our pets, as well as health, animal testing and the impact of meat on the environment. With a balanced variation in plant products, dogs can get all the nutrients they require from plants.

Pet food manufacturers have the option to declare ingredients by using ‘meat and animal derivatives’, which could include animals you don’t find acceptable, such as horses and body parts such as sheep intestines and rabbit ears. Parts of animals which are surplus to human consumption or are not normally consumed by people in the UK are classified as ‘animal by-products’.

There are now a number of vegan approved pet food brands certified by the Vegetarian society. 

Be aware of feeding fruit and vegetables known to be toxic to dogs.

Eating well for a winter health boost! Altruvita’s favourite winter dinner recipes for older adults.

Winter is always a tough time of year for older people, especially those suffering from poor health. The lack of sunlight inhibits our body’s production of Vitamin D, an essential micronutrient for immune system function as well as bone and muscle health. The cold and damp weather can exacerbate join stiffness (though, interestingly, the reasons why this is the case are still being researched) and leave us susceptible to respiratory disease. 

The UK has an aging population, and the associated strain on healthcare and other support service could be problematic, so what can we do to mitigate the impact on society? A healthy and balanced diet plays an integral part in the prevention of age-related diseases, but research shows that older adults aren’t necessarily getting all the nutrients they need.

From data gathered in the UK National Diet and Nutrition Survey (NDNS) 2008–2014, older adults in Britain are currently not meeting important dietary recommendations for their age group:

  • Over 65’s do not get the minimum five portions per day of fruit and vegetables (80 grams is one portion), most do not get the 18 grams a day of fibre either which may be related to this, but also can also be sourced from wholegrains.
  • Over 65’s should have 140 grams of oily fish per week but they are not getting this. 
  • Men aged 65 years and over are likely to exceed the 70 grams per day (on average) of red and processed meat.

Dietary intake in older adults is influenced by an array of factors including wealth, kitchen facilities, cooking skills, mood, strength to cut up food and the help or company that is available. 

Dental status is potentially an important factor. Older adults are susceptible to tooth loss and a large number are missing teeth or have dentures which can impair chewing ability. Consequently, reduced chewing ability may impact dietary eating habits, such as avoiding tough foods that are high in fibre including fruit, vegetables and nuts. That means they may miss out on key nutrients for optimal health in older age. 

Further analysis of the NDNS found that people with dentures have significantly lower levels of average daily intakes of omega 3 fatty acids, fibre, β-carotene, folate, vitamin C, magnesium, and potassium, and had lower blood levels of vitamin B6, vitamin C and β-carotene concentrations. People with dentures were more likely to report difficulty eating apples, raw carrots, lettuce, nuts, well-cooked steak and crusty bread too.

Perhaps you are worried that your diet might be lacking some key nutrients? Here are some meal and snack ideas which could be really helpful:

Fruits

Fruit such as apple, pear, kiwi and melon should be ripe and finely cut. Stewed apple, rhubarb, plums and cherries can be served as desserts. All of these contain high amounts of vitamin C, potassium and fibre. Bananas and raspberries also contain magnesium.

Vegetables

Vegetables should be soft enough and easy to chew and are best left steaming for a bit longer than normal. Try mashing carrot, sweet potato, parsnip or swede into mashed potato. Stewing vegetables in with meat and gravy or tomato-based sauces will deliver an easy to eat, tasty and nutrient-rich meal. Easily to mash pieces of roasted butternut squash pack in potassium, fibre and beta carotene. Peas are well liked as they are soft, naturally sweet and contain folate, vitamin C, fibre and potassium.

Meat

Tender low-fat meats such as chicken or turkey from a whole bird are usually best tolerated and can be served with a cheese sauce or as a well-thought-out roast dinner. Chicken and turkey are also rich in vitamin B6, essential for protein, fat and carbohydrate metabolism

Shepherds/cottage pie: Use quorn, beef or lamb mince with gravy, onion and carrots topped with mashed potato, delivering protein, fibre, beta carotene and potassium. Or even mince in a wholemeal shortcrust pastry topped pie, brushed with egg yolk and served with soft cauliflower cheese always goes down well, packing in potassium, fibre and vitamin C.

Fish

Seafood pies with creamy white wine sauces and peas can form a potato topped pie or mix with tagliatelle – they’re both rich in key nutrients B6, omega 3, folate and vitamin C and potassium. A tender salmon steak served with peas and dauphinoise potatoes is rich in B6, omega 3, vitamin C, fibre and folate. A salmon and broccoli quiche packs in magnesium, omega 3, B6. fibre, potassium, folate and beta carotene. 

Salads

Side salads could include guacamole which includes finely chopped red pepper. This packs in magnesium, fibre, potassium, folate and beta carotene. Roast pieces of butternut squash, peeled cucumber with coriander or mint and mixed into cous cous or rice salads add extra potassium, fibre and beta carotene.

Snacks

Make your own soft red pepper and tomato bread and serve with hummus, this provides vitamin C, potassium, fibre and beta carotene. Or buy a soft wholemeal roll and serve with homemade red pepper hummus for added vitamin B6, beta carotene, magnesium and folate.

A startling fact about British wintertime and vitamin D…

Do you feel a little gloomy and run down in the winter? It might interest you to know that the lack of sunshine during those colder months of the year doesn’t just impact our mood, it actually can impact on our physical health too. Direct sunlight acting on the skin provides the majority of our vitamin D requirement, so when there’s less sun, we make less of this essential nutrient.  

The link between certain health problems and a Vitamin D deficiency has been noted through comparisons between regions with relatively low levels of sunlight, and those that enjoy more hours of sunshine. Incidence of various cancers, irritable bowel syndrome and inflammatory bowel disease have all been linked to low exposure to sunlight and a reduction in the potential of vitamin D production.

You might be deficient in vitamin D if you cover your skin, or if you spend the daylight hours indoors. For individuals living above the north latitude of 35 degrees (which is all of the United Kingdom!), the sun cannot not reach the necessary angle for UVB penetration for all of the winter months. That means that for UK residents there is no opportunity for winter vitamin D production, unless you head to warmer climes for a holiday! 

Vitamin D levels are also strongly linked to mental illness, with a Swedish study showing 58 percent of people who had attempted suicide were vitamin D deficient. They concluded that testing vitamin D levels in mental health care is of vital importance.

Thankfully, vitamin D can also be consumed through dietary sources! There are certain foods that are very rich in vitamin D. Oily fish such as mackerel, salmon and tuna are not only excellent sources of vitamin D, they also contain omega-3 fats that deliver benefits to the cardiovascular system. Among the other foods that can boost your daily vitamin D intake are fortified milk, mushrooms, egg yolks, liver and fortified breakfast cereals. 

Sunlight is our main provider of vitamin D, so over the winter months especially, vitamin D supplementation is recommended for adults and children in the UK.

Add a green tea extract to your new year health kick for additional benefits!

If you’ve made a commitment to kick off the brand-new decade with focus on a healthy diet and more exercise, this blog will certainly be of interest! You’ve probably heard of green tea and know that it’s good for you, but do you know why? Altruvita’s expert nutritional team takes a look at how adding a green tea extract to your routine can deliver a range of additional benefits and what they are. 

What is green tea? 

Green tea is made from unoxidized tea leaves from the Camilla Sinesis bush (whereas black teas are made from totally oxidized tea leaves from various plants) and it has been enjoyed as a drink for centuries. Green tea is widely believed to have a variety of health benefits, so where do they come from? Polyphenol antioxidants called catechins comprise the majority of green tea’s antioxidant content. Among the catechins in green tea, epigallocatechin gallate (EGCG) is the most researched and thought to provide the most health benefits. All of these things are found in more concentrated doses within green tea extracts, rather than diluting these key ingredients within green tea beverages.

How do green tea and green tea extracts support our health? 

Green tea helps to maintain women’s and men’s health* and it helps to reinforce the antioxidant defences of the body, including skin and eyes.* It also maintains healthy gut flora*, which means it feeds the bacteria in our gut, which in turn keeps our immune system functioning.  All of these things are important at this time of year when you’re trying to look and feel better at the same time as fighting off colds and flu.

Recent green tea supplement research

If you are one of the many thousands who are kick starting their year with a regular exercise routine, with a plan to lose weight, you may be interested in some research which was published in September of last year. 

Considering the relationship between cardiovascular diseases (heart disease, stroke) and obesity, the study investigated the effects of a green tea supplement and high-intensity interval training on blood cholesterol, triglycerides, maximal oxygen consumption (VO2max) and other risk factors in overweight women.

Thirty overweight women (aged 20-30), were chosen and randomly divided into three equal groups (green tea alone, or exercise + green tea, or exercise + placebo). They worked-out for 10 weeks doing 40m shuttle runs at maximum effort. Women took 500 mg per day of green tea extract or placebo tablets. 

After 10 weeks, triglycerides, LDL (bad cholesterol), weight, and body fat percentage decreased in all groups. HDL (good cholesterol) and VO2max significantly increased in the exercise + green tea and exercise + placebo groups; whilst in the green tea group they did not, which would be expected without exercise.

It suggests that to get the full health benefits, a green tea extract combined with high intensity interval training exercise is probably the best way to go. Green tea and exercise both have their own unique way of improving different measurements and so collectively provide the best option.

Our carefully sourced green tea extract is low in caffeine and is composed of 98% green tea polyphenols.

The startling effect of pollution on the life expectancy of children growing up in London

New data has been published which aims to predict the impact of 2 different pollutants on the life expectancy of children born in London in 201, assuming they remained living in the city all their life. 

Diesel emissions are the biggest source of air pollution in towns and cities, and a source of some of the most dangerous air pollutants for health: NO2 and particulate matter (PM10 and PM2.5). Diesel vehicles produce more of these dangerous pollutants than their petrol counterparts.

So, what did the researchers find out? Their calculations showed that boys are expected to live 9.5 months less due to the tiny particulates PM 2.5, and 17 months less due to NO– nitrogen dioxide. Girls are expected to live 9 months less due to PM 2.5 and 15.5 months less due to NO2

There are multiple sources of outdoor air pollution, however in urban areas the single biggest source is road transport.  Children in particular are vulnerable to the effects of air pollution from traffic. Even within the womb, a child can be affected by pollution.

It’s no surprise that research as emotive as this has caused people working in the medical profession to take a stand against diesel emissions. ‘Doctors Against Diesel’ is a public health campaign aiming to stop children’s health being affected by air pollution and supporting alternatives to diesel. Many people, rich or poor, spend their lives in cities like London and it does have significant effects on their health. It doesn’t matter who you are, we’re all stuck breathing in the same air.

It’s also worth noting that the risks from air pollution do increase among those living in the most deprived communities, and particularly children in these areas. This is due to the combined impacts of poor housing and air quality indoors, the stress of living on a low income and limited access to healthy food and/or green spaces to exercise.

If you want to protect yourself against the harmful effects of pollution, the best way would be to avoid polluted cities, although of course this is not realistic for millions of people living in the UK.  A diet high in antioxidants and anti-inflammatory compounds is probably going to be helpful for those people living in cities or near main roads, however the research currently sits more with a few food supplements providing benefit.

Suffering from stiff and creaky joints?

Stiffness and aching joints are often associated with winter, in particular the dropping temperatures and increase in wet weather. The exact science behind why colder weather increases joint pain is still slightly unclear, but there’s plenty of evidence to show levels of discomfort rise when it’s cooler. For those living with arthritis or stiff, aging joints it’s worth exploring natural support to get through the winter in comfort. Introducing turmeric, a vibrant yellow spice that could be a secret weapon in the battle against join stiffness and pain. 

Turmeric has traditionally been used in Chinese and Indian Ayurvedic medicine to treat arthritis. Curcuminoids within turmeric are collectively called ‘curcumin’ and we are confident in the science which shows that curcumin blocks inflammatory cytokines and enzymes, including cyclooxygenase-2 (COX-2), in the same way as the common non-steroidal anti-inflammatory (NSAID) painkiller ibuprofen. A study on knee osteoarthritis patients compared the ability of curcumin and another NSAID called diclofenac to inhibit cyclo-oxygenase 2.Both the groups showed significantly reduced cyclo-oxygenase 2 secretions, meaning inflammation levels were lower after the use of a painkiller, but also after the use of curcumin.

Several recent studies show that turmeric/curcumin has noticeable anti-inflammatory properties and it also modifies immune system responses related to arthritis.  A 2006 study showed turmeric was more effective at preventing joint inflammation than reducing joint inflammation. However, a 2010 clinical trial found that a turmeric supplement provided long-term improvement in pain and function in 100 patients with knee osteoarthritis.

One study compared the effects of ibuprofen (2 × 400 mg/day) with those of curcumin (4 × 500 mg/day) in patients who were over 50 years of age, had severe knee pain and their radiography showed the presence of osteophytes. Both the groups showed improvements in all assessments but the curcumin group was statistically better in patient satisfaction, timed walk or stair climbing and pain during walking or stair climbing. 

A pilot clinical study evaluated the safety and effectiveness of curcumin alone, and in combination with diclofenac sodium in patients with active rheumatoid arthritis. Forty-five patients diagnosed with RA were randomized into three groups with patients receiving curcumin (500 mg) and diclofenac sodium, a nonsteroidal anti-inflammatory drug (NSAID). (50 mg) alone or their combination. The curcumin product reduced joint pain and swelling in patients with active rheumatoid arthritis better than diclofenac. More importantly, curcumin treatment was found to be safe and did not relate with any adverse events.

Another study evaluated the comparative efficacy of two different doses of curcumin with that of a placebo in active rheumatoid arthritis patients. Twelve patients in each group received placebo, 250 or 500 mg of the curcumin product twice daily for 90 days. Patients who received the curcumin product at both low and high doses reported statistically significant changes in their clinical symptoms at the end of the study. These reported changes were backed up by changes seen in patients’ blood tests. 

Curcumin+ is a powerful anti-inflammatory*, antioxidant* formula that helps support inflammatory issues for optimum wellness. It helps protect and support joint comfort and flexibility*.

Banish smartphones and turn WIFI and TVs off for better quality sleep

You may remember the news from last year that the artificial blue light emitted by our smart phone screens is too stimulating for our brains at bedtime, but did you know that there are also plenty of other electronic devices which can impact sleep?

WIFI emits Electromagnetic Frequency radiation (EMF).  In 2013, the Department of Electrical and Electronic Engineering at The University of Melbourne published a study on how EMF affects the quality of our sleep, especially in relation to the pineal gland which sits in the brain.

They found that our bodies sense EMF radiation in a similar way to how we perceive light. The pineal gland (the gland responsible for producing melatonin, the hormone that regulates our sleep and circadian rhythm) slows down production. When we’re unable to get proper sleep, our ability to fight bacterial, viral and fungal infections and repair tissue damage is impaired. Sleep is one of the most important parts of a healthy lifestyle, and EMF radiation dramatically affects our ability to get that sleep- a fact also understood by NASA.

Turn your WIFI off at night.

And it’s not just WIFI that effects the quality of our sleep, a new study published in JAMA Internal Medicinedraws a very interesting link between weight gain and sleeping with a television on.

The study followed women between the ages of 35 and 74, and showed that sleeping with the TV on, or any other source of bright light in the bedroom, led to weight gain. The data from a five-year period shows that those who have a TV or other light source on while they sleep gained over 10lbs during the period of the study.

We are meant to sleep in the dark, we are equipped with a pineal gland to wake us up at sunrise.

Getting enough solid sleep every night is one thing essential to health, and lack of sleep has indeed been associated with a variety of conditions. Lack of deep sleep and not getting enough sleep overall are both correlated with obesity.

Artificial light has been shown to hamper sleep quality, and that’s one of the reasons why blue-light-dimming features have crept into our mobile devices and computers. Remember, no phones under your pillow either! Why not buy an old-fashioned alarm clock and banish tablets and smartphones from the bedroom altogether?

As well as embracing darkness and electronic device-free zones to promote better quality sleep, it might interest you to know that hops have been known for their calming abilities for centuries. This is thought to be partly due to the xanthohumol that they contain, which induces mental wellbeing and brings better sleep*. Take a closer look at our Hops and Dreams supplement here
