How smartphone and tablet screens impact sleep

Research has shown that the light from smartphones, tablets and other screens is having a detrimental impact on our sleep because many emit blue light. Here’s why...

BLUE LIGHT

Blue light is all around us. One of the biggest producers of blue light is the sun. The blue light from the sun collides with air molecules causing blue light to scatter everywhere. This is what makes the sky look blue. In its natural form, your body uses blue light from the sun to regulate your natural sleep and wake cycles. This is known as your circadian rhythm.

PINEAL GLAND

Evolutionarily, this made sense. When the sun goes down in the evening, the amount of natural blue light is reduced, signalling to the pineal gland, a pea-size organ in the brain, that it’s time to rest.

MELATONIN

It does this by releasing the hormone melatonin before your regular bedtime. Melatonin reduces alertness, preparing us for sleep.

But looking at screens in the evening stops our bodies from producing melatonin at bedtime, breaking our circadian rhythm and natural sleep cycle; and making us less ready for a good night's sleep.

IMPACT ON SLEEP

Studies have found that those who read with a tablet at night get a poor quality sleep and feel less alert than those who read their bedtime stories from a paper book.

So get a better night's sleep and switch off any devices at least an hour before bed!
