Did you know that just 30 minutes’ phone usage before bedtime is thought to delay REM sleep by 30 minutes?*
A Harvard University sleep researcher has claimed that exposure to light at night time is one of the reasons that many people are so sleep-deprived**. Chronic lack of sleep is linked to an increased risk of a whole host of ailments including diabetes, cardiovascular problems and depression. That’s not to mention feeling tired and cranky the next day!
Blue light has been found to be a powerful melatonin suppressant. Melatonin is the hormone that influences your circadian rhythm (or ‘body clock’), and when your circadian rhythm is disrupted, your sleep can suffer.
Staying up late at night browsing on your smartphone can therefore sabotage a good night’s sleep.
Whilst we would never recommend spending hours browsing your smartphone anyway (see Electrostress), this anti blue light phone screen protector from WaveWall is ideal for helping to keep your body clock in check.
This sleek tempered glass phone screen protector not only filters out blue light; it also protects your screen from minor scratches. The image quality remains unaffected, so you can rest assured you will still be able to browse your phone with ease.
Each one comes with a handy application kit to help you apply your screen protector perfectly.
