Medical disorders are exactly what we ve been discussing. The term just covers a broader range of problems. We speak of an immune disorder, a genetic disorder and sleep disorders. The last one provides an excellent point on which we can end this part of the discussion. Some sleep disorders are true medical conditions and some are not.
Sleep apnea is a true sleep disorder.
It is a term used for people who have difficulty breathing while in deep sleep. They struggle to inhale and often need a machine to keep their airway open at night. Besides not being well-rested, this problem can lead to lung and heart complications. Other people have sleep disorders because of work pressures or other worries. Good sleep returns when the problem is lifted.
