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 and other devices off at night
And it’s not just WIFI that effects the quality of our sleep, a new study published in JAMA Internal Medicine draws 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.
