Most people these days have their smartphones on their bedside table rather than a book. The time you have in bed before you sleep is an amazing time to catch up on texts, emails, and your newsfeed.

It turns out that the type of light emitted by your smartphone is messing up the normal hormones in your body that help you fall asleep. You may think that the only downside to this may be feeling a little groggy in the morning after a late night, but that isn't the only problem. Browsing your phone in bed may be making you gain weight. The details are pretty incredible...

Your body adjusts its levels of hormones in a way that reflects the rising and setting of the sun.

You may have heard of melatonin, a sleep hormone that is released as darkness builds in the evening. You've probably heard of melatonin because it's mass-produced in the form of a pill that you can buy over the counter at your local pharmacy. 

Another hormone, insulin, plays a role in regulating your blood sugar and stays low at night.

If you look at a bright phone screen, you're telling your brain to produce less melatonin. Basically, you're telling it to stay awake.

Below is a simulated graphic showing what might happen when you browse your email or newsfeed in bed. With a phone, your natural rise in melatonin can be significantly lowered, and insulin levels may fluctuate as a result. This has consequences for the speed of your metabolism...

This disruption to sleep may also impair the ability of the brain's glial cells to properly clean toxins from the day.

So how does this affect someone in ways that they can notice?
