EXYRA asks the Expert - Olivia Arezzolo: How can I protect against blue light and sleep better?
Finding it hard to switch off at night?
Love watching Netflix to fall asleep?
Scrolling just before bed?
If so - this article is for you.
As a sleep expert with over 9 years of academics, plus partnerships with global giants Sealy Posturepedic and IKEA; on behalf of EXYRA, it’s a pleasure to shine an insight into the key reason your sleep is suffering: Blue Light.
What is blue light?
Blue light is a specific spectrum of light between 400-525 nanometers shown in clinical trials to sabotage sleep.
Exactly how does blue light destroy sleep?
Research in shows blue light regulates your circadian rhythm - dictating how sleepy and alert you are. Specifically, it controls the release of melatonin - the hormone to make you sleepy.
Under the presence of blue light, the body produces less melatonin than usual. As a result, you don’t receive cues to become sleepy, and are likely to struggle to fall and stay asleep.
Specifically, studies show blue light for 2 hours before bed suppresses melatonin by 38%. Even just an hour before, melatonin levels were suppressed by 23%.
For those finding it hard to switch off at night, this could be the exact reason why.
Where does blue light come from?
Artificial lights - phones, TVs, laptops, ceiling lights and street lights.
How can I protect against blue light?
Ideally, switching off all artificial lights after dark is ideal. However, when this isn’t possible, wearing a pair of is helpful.
EXYRA’s (ever-so-stylish) clear lenses block out 50% of harmful blue light, which means sleepiness hormone melatonin is still able to be produced.
As a result, you’re able to fall and stay asleep easier - even if you are watching Netflix or scrolling social.
