Sleeping Too Much

We all know that a good night’s sleep is important for good health. The human body needs to rest and rejuvenate. Important body functions of growth and repair take place during sleep. Without enough rest, energy levels drop, immunity decreases, and mental functions slow. However, although sleep is vital, it is possible to get too much of a good thing. Too much sleep may be a sign of underlying health conditions. Likewise, excessive sleep can contribute to an increased risk of several disorders. Read on to explore possible links between excessive sleep and poor health.

12. How Much Sleep Is Too Much?

Much Sleep

Different individuals need varying amounts of sleep. Most adults require seven to nine hours of sleep each night. Excessive sleep doesn’t refer to those individuals who function well on nine hours of sleep each night. It also does not refer to occasionally sleeping in until noon on a weekend or when catching up from travel or a string of late nights. Instead, excessive sleep refers to those who chronically require more than 10 hours of sleep each night. Additionally, these individuals may find that they are groggy, fatigued, and lacking in energy even after such a long night of sleep.

11. Increased Risk of Heart Disease and Stroke

Risk Of Heart Disease

Just like sleeping too little, sleeping too much can lead to an increased risk of heart disease. A study in the European Heart Journal suggests that sleeping six to eight hours each night is optimal for heart health. In this study, either more or less sleep increased the risk of heart disease and death. Furthermore, a British study in Neurology suggests that excessive sleep increases the risk of stroke. In both studies, the risk of disease follows a J-shaped curve. This means that the risk of disease first falls, then steeply rises with increased amounts of sleep.
