Sleep and Disease – what is sleep and disease?

At first glance, the cost of poor sleep is actually much greater than many people think. It may have profound consequences for our long-term health. According to research about sleep and disease, people who consistently fail to get enough sleep are at an increased risk of chronic disease, and scientists are starting to understand why. Considering sleep as a priority rather than a luxury could be an important step in preventing a number of chronic diseases.

Sleep and disease – The Relationship between Sleep and Health

We all have some sense of the relationship between sleep and our ability to function in a day. After all, we’ve all experienced fatigue, bad mood, or lack of focus that usually follow a night of poor sleep. What a lot of people don’t realize is that how lack of sleep on a daily basis is often the cause of long-term health consequences such as chronic medical conditions that include diabetes, high blood pressure, and heart disease. It may even lead to a shortened life expectancy. Also, sleeping for more than nine hours is associated with poor health.

Researching the Link between Sleep Duration and Chronic Disease

There are three main types of studies that help us understand the links between sleep habits and the risk of developing certain diseases.

Sleep and Disease – Sleep Deprivation

The first one is sleep deprivation studies which involve depriving healthy research volunteers of sleep and examining any short-term physiological changes that could trigger diseases. Studies have revealed that sleep deprivation is often associated with potentially harmful effects such as increased blood pressure, impaired control of blood glucose, and increased inflammation.

Sleep and Disease – Cross-sectional Epidemiological Studies

The second research is called cross-sectional epidemiological studies — it involves examining questionnaires that provide information about habitual sleep duration and the existence of a particular disease or group of diseases in large populations at one point in time. For example, both reduced and increased sleep duration, as reported on questionnaires, is linked with hypertension, diabetes, and obesity. Although, cross-sectional studies can’t explain how too little or too much sleep leads to disease because people may have a disease that affects sleep, rather than a sleep habit that causes a disease to occur or worsen.

Sleep and Disease – Longitudinal Epidemiological Studies

The third and last, the most convincing type of evidence that long-term sleep is associated with the development of numerous diseases comes from tracking the sleep habits and disease patterns over long periods of time in individuals who are originally healthy. It is still unsure whether adjusting one’s sleep could reduce the risk of disease development or lessen the severity of an ongoing disease. However, the results from epidemiological studies are beginning to suggest that it is probable.

Sleep and Disease

Sleep is often unconsidered as a big deal for some people, but it really is. It’s more important than we think since sleep is basically charging your body like how you do it to your gadgets. Therefore, better get some good sleep not only to give yourself a rest but also to lessen the chances of chronic diseases. So, be aware of the connection between disease and sleep.
