When the dun sets, the cells will detect drop in light intensity making the brain release melatonin. Melatonin is responsible for inducing fatigue and relaxation which signals the body that its sleep time.

Due to having lamps, bulbs and electronics in the bedroom, you may be exposed to too much light. Some electronics like the TV, laptop, and cell phone have blue light which keeps the body from producing melatonin and this keeps you from falling asleep. The light tricks the cells into believing its day and keeps the body from producing natural melatonin for sleep.

To counter the negative effects of light, make sure there is no light in your room during sleep time. Shut down all electronics and get blackout curtains to block any lights from moving vehicles or the neighbours. If you must keep some of the devices on, make sure they have on a blue light filter or get eye masks to keep the light away when you want to fall asleep fast.
