Relaxation and Sleep

Rest and relaxation are necessary to overcome the fatigue which results from daily activities. Strength is not built up unless activity is continued long enough to cause some fatigue. During rest fatigue disappears. Sleep is a state of partial unconsciousness from which one can be aroused to stimulus. Sleep is essential to a person as food, air and water for the normal functioning of the brain and other physiological activities. A growing child needs more sleep so that the energy can be directed to the process of growth. It is also during sleep one is able to recover from fatigue. When sleep sets in, body is completely at rest. All voluntary activities like locomotion and feeling are suspended.
