Sleep is a fundamental process that helps us to recover from the day’s activities. It is a natural part of life and it should not be neglected. However, sleep is not very easy to achieve, even though it has been proven that we can get some rest during the day. We are used to thinking of sleep as a passive activity, which we do when we are resting from our daily activities. However, sleeping well requires different skills than just resting from our daily activities. We need to have good posture and keep our body relaxed for at least 30 minutes every day in order to get enough sleep. Even though this sounds simple enough, it is actually quite difficult for many people because they don't have time for this activity and simply don't know how to do it properly.
