The Connection Between Light & Sleep
Constant light exposure while you are sleeping tricks your brain and messes with your internal clock. This makes it difficult for the body to distinguish between night and day. It inhibits the production of the melatonin, which is a hormone that helps your body sleep, thereby resulting in psychological consequences.  Interestingly, the effects seem to be more pronounced in younger people than older people. This is because eyes tend to be more sensitive when you are young and hence become irritated by light easily while trying to fall asleep.

When the room is not dark enough, you tend to wake up constantly throughout the night. This prevents your body from going into a deep sleep state. Unless the body gets the necessary hours of deep sleep every night, it can make you irritable and unproductive the next day. A good quality sleeping pillow will help you fall asleep faster.

In order to prepare your body for bedtime, it is a good idea to follow a routine that includes darkening your environment. This involves dimming the lights to help with the physiological progression towards sleep. A dimmer switch is useful for this purpose. You also need to avoid screen time to help your brain get ready for bedtime. Screen time has the ability to stimulate your brain and prevent you from falling asleep quickly. The blue light emitted from these screens also plays havoc with the body’s internal clock. If you live in the city, it might be difficult to achieve complete darkness in your bedroom. It is a good idea to invest in an eye mask and a good mattress for sleep.
