Studies have shown that being exposed to the blue-and-white light given off by phones, laptops and other electronic gadgets at night prevents our brains from releasing melatonin, a hormone that tells our bodies it’s nighttime. All this screen time may be eating away at our sleep. That means it takes us longer to fall asleep. And many years of delaying sleep, researchers think it can mess with our internal body clocks.
If your phone or tablet is probably the first thing you look at in the morning and the last thing you look at before bed then you should know that what happens to your body, have a look:
1. Less sleep impairs your memory the next day.
Almost all of us have experienced a heavy head due to lack of sleep. If you’re anything like me and guard your memory well, you need to put yourself through 6-8 hours of sleep and let your active neurons rest daily.
2. Over the long term, lack of sleep builds neurotoxin up in the body and makes it even more difficult to get a good sleep.
So, sleep supports the glial cells that are important when it comes to cleaning up the neurotoxins, that build up in our brains throughout the day. If we don’t get enough sleep, these glial cells fail to perform their jobs. Result? More neurotoxins.
3. People whose melatonin levels are low are more prone to depression.
Sleep less, mess with your sleep schedule, deprive yourself of melatonin, fall prey to depression. This is the worst thing ever and yet, we fall prey to it unknowingly.
4. The blue light might damage our vision by harming the retina over time or it may lead to cataract.
Constant use of this blue light may be a terrible idea, your retina will agree.
Even if it is not confirmed, and studies are still investigating it, the blue light from your smartphone could be the cause behind your (future) cataract.
5. There is also an increased risk of breast and prostate cancers.
6. Poor sleep leaves you distracted and makes it harder for you to learn new things.
Lack of sleep, apart from making us feel extremely tired, also disrupts with our hormones and normal body functions. Your cognitive abilities go for a toss, and well, we aren’t quite ready to sacrifice that, are we?
