We all do it… get all tucked up in bed and then have a quick browse of Facebook, check your texts, watch a quick cat video. But there are actually some serious ramifications of these seemingly harmless habits. Bright artificial light can wreak havoc with your circadian rhythm, the internal clock that regulates your sleeping habits. At around 9 pm at night, the body releases a hormone called melatonin, which signals the brain that it’s time to sleep. However, staring at screens within the hour immediately before sleep can suppress the production of melatonin by 22% severely damaging a person’s ability to drift off. This is a much more serious problem than you might initially think. A loss of sleep has been conclusively linked to depression, obesity, diabetes and even serious cardiovascular disease. And it’s becoming quite a pandemic. A study by the National Sleep Foundation found that a huge 95% of those surveyed use electronics in the hour before bed, and 63% felt they were not getting enough sleep.
