It’s been proven that our quality of sleep has been on the decline for years, but are our smartphones to be held partly accountable?
Blue light – the type of light emitted by our smartphones, tablets and anything with a screen – has been discussed widely in recent years as a ‘good for your health, bad for your sleep’ debate.
The issues surrounding blue light have been on scientists radars for years, with experts concluding it can be detrimental for our sleeping patterns if we spend too much time on our electronic devices before sleeping.
But it’s not all doom and gloom, blue light is actually good for you in moderation. Research shows it can help you feel more awake, more energised, boosts alertness and elevates memory; which is probably what’s keeping us awake at night.
So what’s the problem and what should we do?
The problem with blue light, especially on your phone, is that it tells your brain that it’s not yet time to go to bed, stimulating the brain to become more awake. With natural light, our circadian rhythm has, for centuries, been determined by the sun and so our electronic devices are interfering with nature.
Device manufacturers have recently picked up on the effects of blue light and most have introduced a feature to switch on a Night Shift mode, reducing it’s effects.
