How Light Exposure Impacts Your Sleep

How are you sleeping these days? If you don’t like the answer to that question, then it might be time to make some changes. The problem with learning how to improve the way we sleep is that there are just so many possibilities for change out there. There are a lot of things you can to get better rest. At the same time, there are unfortunately a lot of things that can get in the way of your sleep, as well.

Believe it or not, but your problem might be your exposure to light through the day, particularly at night.

How Light Exposure Effects Sleep

When it comes to how you sleep at night, one thing you are going to want to pay attention to is melatonin. This natural hormone in your body is dictated by your body’s exposure to light. Generally speaking, when it is light out, your melatonin levels are pretty low. When it starts to get dark, your body will begin to produce more melatonin, which in turn is going to help to make you sleepy. This isn’t the only thing that contributes to your sleep, but it is certainly something that almost everyone should keep in mind.

The problem with healthy melatonin levels is that there are way too many things in our daily lives that can serve to screw them up. Staring at screens at work all day, and then coming home to tons of bright lights, both on the streets, and in your house, can all play an impact in how your body produces melatonin. To that end, it is worth appreciating that we can’t change certain things about our lives. However, there are still things you can do, in terms of taking advantage of the fact that your relationship to light exposure needs to change.

Exposing yourself to bright sunlight during the day can certainly help. Even something as simple as having breakfast beside a sunny window is a good way to get you started, help you to feel more alert. Spending more time outdoors during daylight hours can also prove to be useful, and keeping as much natural light in your home during the day as possible can definitely benefit. At night, you should try to stay away from bright screens, up to two hours before you go to sleep. Late-night TV watching can actually suppress your melatonin, which can make it hard to fall asleep. A dark room is also pretty essential.
