With busy schedules and many activities filling our days, sleep is a vital time for the mind to rest and the body to repair. Without the proper amount of sleep, our bodies suffer, we become cranky, and our ability to be productive and efficient during the day drops. In addition, prolonged sleep deprivation may affect how the immune system protects our bodies and is able to fight for us when we do get sick.
During rest, however, tissues have a chance for repair and growth and the muscles relax as well as receive more blood supply. Certain hormones for growth and development are released during sleep. Good rest is a vital component of a balanced lifestyle.
