2. Bed is for sleeping
Our brains work in a very funny way. You can trick it to believe everything and almost anything. The idea here is that every time you lay down in your bed, your mind should understand that it is for sleeping only. In order to do that, you should prohibit yourself from taking any sort of gadgets while on the bed, or even watching the TV while sitting or lying on it. On the other hand, make sure you don’t watch any TV or use the smartphone before bed as the blue radiation from these gadgets make it hard to fall asleep.
