Sleep is a vital component of good health. Not getting enough sleep can lead to disease and illness, such as diabetes, cardiovascular disease, obesity, and depression. The Center for Disease Control (CDC) points out that the lack of sleep actually contributes to the onset of these illnesses, not just that they contribute to ill health once a person has a disease.
The medical community recognizes that there are two forms of insomnia. Primary insomnia is when a person is having sleep problems that are not directly associated with any other health condition or problem. Secondary insomnia means that a person is having sleep problems because of something else, such as asthma, depression, anxiety, arthritis, cancer, pain in the body, or substance abuse. Lack of sleep might also happen because of necessary medication for another illness.
The following will explore the diseases mentioned here in order to shed light on the physical and mental illnesses associated with insomnia.
