Relaxation refers to a state of being relaxed, without any stress, anxiety, or tension. There are many relaxation quotes to be found if you spend a few minutes searching, and these show how important this state is for humans. While you sleep you are experiencing full relaxation most of the time, but only if you go to sleep without any worries or concerns that could trouble you while you are out. Relaxation may also be referred to as unwinding or letting go of stress. The human body needs periods of relaxation so that healing and growth can occur. If your muscles never showed relaxation they would always be tense, and eventually soreness would set in as a result. The art of relaxation does not come naturally to some people, and these individuals must make a conscious effort to relax.
