Getting sufficient sleep does not guarantee health, but it does play a major role in your body's ability to maintain itself. Its most important benefit is that it helps your body to bounce back from the stresses placed on it by daily life. Failing to get sufficient rest can make you vulnerable to a number of health problems, including:
Respiratory Ailments
Sleeplessness can weaken your immune system leaving you more vulnerable to problems with your respiratory system. For example, being sleep-deprived can make you susceptible to getting colds or influenza. If you are suffering from chronic lung disease, sleeplessness will probably cause it to get worse.

Cardiovascular Problems
People who are sleep-deprived are more prone to weight-gain, which means that they are more likely to have cardiovascular problems as well. Sleep plays an important role in your body's ability to heal your heart and blood vessels and the lack of it increases your risk of high blood pressure and stroke. Studies have shown that a single night without sufficient rest can cause people with hypertension to have an elevated blood pressure all through the following day.
Diabetes
A study by the University of Chicago's Department of Medicine and the Institute of Neuroscience at Northwestern University found that being sleep-deprived can increase a person’s risk of developing type 2 diabetes. The good news is that better and longer sleep has the effect of improving control of blood sugar and of reducing the effects of type 2 diabetes.
Central Nervous System Problems
When you are asleep, the brain rests its neurons and builds new pathways. Sleeplessness results in a brain that is unable to function properly and along with sluggishness, your short- and long-term memory will suffer. If you are prone to manic depression, being sleep-deprived can bring on mania along with a variety of other conditions such as depression and paranoia.
Mattresses play a significant role in both the quality and duration of your sleep. For example, a mattress that does not adequately support your body may lead to back pain and sleeplessness. In order to ensure your long-term health, it is important that you carefully consider the surface on which you sleep. Research and evaluate mattresses to find the one that is most comfortable for you and that is most likely to enhance your rest.
