Can people sleep too much? If so, what are the negative effects of too much sleep?

It is possible to get too much sleep. In fact, if you sleep more than seven or eight hours a night and still feel tired the next day, it could be a sign of an underlying health problem. You should see your doctor to make sure you don’t have anemia (too few red blood cells) or a thyroid problem. These often make people feel very tired.

Some studies have linked sleeping too much with higher risks of diabetes, obesity, headaches, depression, back pain and heart disease. So if you’re worried about sleeping too much, you shouldn’t ignore it. And, if you think a sleep disorder could be to blame for your drowsiness, keep a sleep journal and go over it with your doctor. Jot down what time you went to bed, about what time you fell asleep and woke up, how well you think you slept, how you felt when you woke up and how you felt through the day.
