Sleep deprivation is a condition of not getting enough sleep. This condition occurs if a person has a sleep disorder, sleeps at the wrong time of the day or does not get sufficient sleep. Like food and breathing, sufficient sleep is important to the general well-being of a person and aÂ deficiency of sleep may lead to poor productivity, mental problems and even injuries.
A person's ability to perform well depends on whether he or she gets enough sleep. It also depends on whether a person is sleeping at the time when their body wants to have a rest. The human body is able to control when sleep is needed and when the person is ready to be awake. This affects everything in the body including cells, tissues and organs. Not getting enough sleep or sleeping during the wrong time makes a person feel tired during the day.
Sleep deficiency affects people of all ages and it is one of the most common health problems in the United States. Seven to 19 percent of adults in America do not get enough sleep, as stated by the Centers for Disease Control and Prevention. Also, 40 percent of adults claim to fall asleep during the day. Sleep deficiency is associated with chronic health issues, such as obesity, heart disease, depression, stroke and diabetes.
