Share the post "Use Of Smartphone At Night Isn’t Smart Enough"
It is a common habit among us to check our facebook feed one last time before we fall asleep.
While it may sound harmless, it may have serious consequences. A report says, that using your smartphone, tablet, or any other electronic device before bed on a regular basis can actually have a detrimental long-term effect on your health.
A new report from gigaom breaks down how exposure to the artificial blue light that emanates from our smartphone screens can damage your sleep cycle and your health.
It’s been known for quite some time that blue light impacts the way your body produces melatonin, the chemical in your body that makes you feel sleepy.
Just a few months ago, the american chemical society posted a video explaining that exposure to blue light at night essentially tricks your body into thinking its morning, which messes with your circadian rhythm and makes it harder to fall asleep.
But melatonin does more than help us fall asleep — it also slows the progression of cancer and other diseases.
Gigaom’s report mentions a lot of reasons why using devices such as smartphones, laptops, tablets, and televisions before bed can be bad for your health and here are some of the most important points.
Harmful for eyes
Optometrists are said to be seeing higher levels of retinal stress in young people that could lead to disorders such as macular degeneration. In extreme cases, this can cause near blindness. This exposure can also cause retinal toxicity.
A lack of melatonin could make you more vulnerable to disease. According to the us national library of medicine, a lack of melatonin is linked to higher rates of breast, ovarian, and prostate cancers.
moreover, it can make you moody, too. Exposure to blue light has been said to have an impact on peoples’ mood. At the same time, lower melatonin levels in mice have been linked to higher rates of depression, say studies.
so does that mean you shouldn’t watch tv or use your computer at night? The national sleep foundation suggests that you avoid dozing off with the tv on.
