Too much sleep — as well as not enough sleep — raises the risk of chronic diseases, such as coronary heart disease, diabetes, anxiety and obesity in adults age 45 and older. Sleeping too much puts you at greater risk of coronary heart disease, stroke and diabetes than sleeping too little.
We often say that people need 7-9 hours of sleep, but some people require more sleep to feel rested. “Long sleepers” are people who regularly sleep more than the average person their age. As adults, their nightly length of sleep tends to be 10 to 12 hours. This sleep is very normal and of a good quality.
Too much sleep on a regular basis can increase the risk of diabetes, heart disease, stroke, and death according to several studies done over the years. Too much is defined as greater than nine hours. The most common cause is not getting enough sleep the night before, or cumulatively during the week.
If you average more than seven or eight hours of sleep per night, see a doctor for a checkup. The doctor can help you determine why you oversleep. If your oversleeping is caused by alcohol or certain prescription medications, cutting back on or eliminating the use of these substances may help.

Sleeping a lot isn't necessarily a bad thing. Sleep is important. Not getting enough sleep puts you at risk for health problems, from heart disease to obesity to diabetes.

Editor's note: Kleine-Levin Syndrome mostly affects teen boys, causing them to sleep up to 20 hours a day during episodes that can last weeks. It's rare, possibly affecting one person in a million, with a higher incidence among Jewish people. There is no definitive cause or treatment.
A person with an 8-hour sleep need who gets 6 hours each day for 5 days builds a sleep debt of 10 hours. As sleep debt builds, brain and body functioning deteriorate. Sleep is needed to “pay down” this debt.
Sleep feels good because when we rest, our bodies produce melatonin, which controls our sleep patterns. Our melatonin levels increase at bedtime, making us feel tired. Melatonin, secreted by the pineal gland, makes us feel cozy and relaxed, allowing our bodies to get the time off they need at the end of each day.
Strong scientific evidence shows that our brains benefit from a brief period of actual sleep (a nap), not just a quiet period, to recover from fatigue and to help restore alertness. Both short (15-30 minute) and long (1.5-hour) naps can increase alertness. During the daytime, a brief nap is recommended.
Like insufficient sleep, oversleeping is a sign of disordered sleep. It may be connected to a mental health issue, such as depression. It's often a signal that a person is experiencing poor sleep quality, and it can be a sign of a clinical sleep disorder, including obstructive sleep apnea or narcolepsy.

Sleep anxiety is fear or worry about going to sleep. You may be apprehensive about not falling asleep or not being able to stay asleep. Some people also have a distinct phobia, or fear, about sleep called somniphobia.
Spending excessive time in bed may be a sign of an underlying medical condition, such as depression. Depression is a mood disorder that has many symptoms, including decreased interest in activities or other people, weight changes, trouble sleeping, and fatigue.
Due to it taking time to dissipate, melatonin is still present in our bodies when we wake up. This is the reason why we get that comfortable feeling upon waking, and why we end up staying in bed.
“Physical closeness with a partner while in bed can stimulate the release of oxytocin, which has been shown to promote a sense of calm and relaxation, which may benefit sleep,” says Dr. Troxel. This release of sleep-promoting oxytocin can take place regardless of any intimate acts between the two of you.
Napping can both help and hurt sleep debt. If you didn't get enough sleep the night before, a nap can help you feel less sluggish during the day. Keep your naps short. Aim for 10 to 20 minutes.
