Obtaining too little sleep upsets the balance of these and other hormones. Research into the mechanisms involved in regulating metabolism and appetite are beginning to explain what the connection between sleep and obesity might be.ĭuring sleep, our bodies secrete hormones that help to control appetite, energy metabolism, and glucose processing. Sleep is now being seen as a potential risk factor for obesity along with the two most commonly identified risk factors: lack of exercise and overeating. For example, studies have shown that people who habitually sleep less than six hours per night are much more likely to have a higher than average body mass index (BMI) and that people who sleep eight hours have the lowest BMI. Several studies have linked insufficient sleep and weight gain. Insufficient sleep has been linked to a high probability for weight gain. However, the results from longitudinal epidemiological studies are now beginning to suggest that this is likely.

We do not yet know whether adjusting one’s sleep can reduce the risk of eventually developing a disease or lessen the severity of an ongoing disease. The third and most convincing type of evidence that long-term sleep habits are 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 initially healthy (i.e., longitudinal epidemiological studies).

However, cross-sectional studies cannot 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. For example, both reduced and increased sleep duration, as reported on questionnaires, are linked with hypertension, diabetes, and obesity. The second type of research (called cross-sectional epidemiological studies) 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. Such studies have revealed a variety of potentially harmful effects of sleep deprivation usually associated with increased stress, such as increased blood pressure, impaired control of blood glucose, and increased inflammation. The first type (called sleep deprivation studies) involves depriving healthy research volunteers of sleep and examining any short-term physiological changes that could trigger disease. There are three main types of study that help us understand the links between sleep habits and the risk of developing certain diseases. Researching the Link Between Sleep Duration and Chronic Disease Additional research studies show that habitually sleeping more than nine hours is also associated with poor health. What many people do not realize is that a lack of sleep-especially on a regular basis-is associated with long-term health consequences, including chronic medical conditions like diabetes, high blood pressure, and heart disease, and that these conditions may lead to a shortened life expectancy. After all, everyone has experienced the fatigue, bad mood, or lack of focus that so often follow a night of poor sleep. We all have some sense of the relationship between sleep and our ability to function throughout the day. Not getting enough sleep can have profound consequences on a daily and potentially long-term basis for your health and mental well-being.
