Certain sleep disorders are linked to oversleeping. These include obstructive sleep apnea and circadian rhythm disorders. Frequently oversleeping for over three months and waking up without feeling rested may also be a sign of hypersomnia, a sleep disorder linked to excessive tiredness and oversleeping.
How Much Sleep Is Too Much? Sleep needs can vary from person to person, but in general, experts recommend that healthy adults get an average of 7 to 9 hours per night of shuteye. If you regularly need more than 8 or 9 hours of sleep per night to feel rested, it might be a sign of an underlying problem, Polotsky says.
Yes, it is. And sleeping too much — 10 hours or more — can harm your health. Further, it may be a sign of underlying health problems, according to a study by the Centers for Disease Control and Prevention (CDC) published by the American Academy of Sleep Medicine.
Hypersomnia means excessive sleepiness. There are many different causes, the most common in our society being inadequate sleep. This may be due to shiftwork, family demands (such as a new baby), study or social life. Other causes include sleep disorders, medication, and medical and psychiatric illnesses.

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. However, sleeping a lot all of a sudden when you didn't before might be a reason to look closely at what is going on with your health.
Hypersomnia is a condition in which people have excessive daytime sleepiness. This means they feel tired during the day. Hypersomnia can also include situations in which a person needs to sleep a lot. This may be due to other medical conditions, but can also be due to a problem in the brain.
“While consistently getting less than the recommended amount of sleep has been associated with multiple adverse health outcomes, sleeping more than nine hours per night regularly may also be detrimental,” Makekau says.

Could a sudden increased need for naps indicate a health problem? If you're experiencing an increased need for naps and there's no obvious cause of new fatigue in your life, talk to your doctor. You could be taking a medication or have a sleep disorder or other medical condition that's disrupting your nighttime sleep.
If you or a loved one feel sleepy or fatigued, despite having 7-8 hours of sleep, it could indicate poor sleep quality or be a sign of an underlying sleep disorder. If you have questions or concerns about your sleep health, please speak with your primary care provider.
There could be a variety of reasons why you are still tired after sleeping for 8 hours. It could be due to poor sleep quality, lifestyle factors such as stress, poor diet, and lack of exercise or an underlying health condition.
If you aren't feeling rested when you wake up, despite getting to sleep at least 8 hours prior, then it might not be the quantity of your sleep that's the problem. It could be your sleep quality that needs some attention. The amount of sleep you get is important, but equally important is the quality of that sleep.
“It becomes kind of like jet lag,” says Dr. Winter. “You wake up feeling kind of groggy, like you have a dull headache, maybe a bit of nausea, and lethargy—you just don't feel like doing anything.” Your best bet is to resist the urge to nod back off after you wake up.
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.
Research has shown that it can take up to four days to recover from one hour of lost sleep and up to nine days to completely eliminate sleep debt. View Source . A full recovery from sleep debt returns our body to its baseline, reducing the negative effects associated with sleep loss.
“There is no such thing as a “fixed or ideal time” to go to bed which will suit all individuals. It is generally advisable to fall asleep between 10 pm to midnight as for most people this is when the circadian rhythm is at a point that favours falling asleep.”
“Women are also multi-taskers, and they do a lot at once. Because they use more of their actual brain, they may need a little bit more sleep than men. It is still debatable, but some experts say that women need twenty more minutes on average than men usually need.”
Sleep and Aging
Older adults need about the same amount of sleep as all adults—7 to 9 hours each night. But, older people tend to go to sleep earlier and get up earlier than they did when they were younger. There are many reasons why older people may not get enough sleep at night.
