From effecting the quality of sleep and sleep patterns, a Tech Radar report investigates the impact of technology use on sleep and overall health.

Good quality sleep contributes to a long and healthy life. It’s our body’s chance to recuperate after a long day of work. However, technology can interfere by affecting our levels of melatonin, the hormone that helps us fall asleep and maintain healthy sleep cycles.

Saj Devshi, a psychology and sleep expert, explains that the blue light emitted by devices can impact the sleep process. And you don’t even have to use a device before bed to experience the effects – just having tech in your bedroom can be as bad.
“Gadgets such as laptops and mobile phones, as well as even the standby light from our television sets, can all affect healthy sleep patterns without us even realising it,” says Devshi. “This is because any form of light, even artificial light, disrupts our body from releasing melatonin, which is the body’s natural sleep hormone.”

“A lot of people like to sleep with their mobile phone next to them without realising that this can cause broken sleep. Every time a notification comes in, our body can detect this emitted light and thinks it’s time to wake up, so stops producing melatonin. This is why we sometimes feel quite physically and mentally tired the next morning.”
