Is 10 hours of sleep too much?

Seven to nine hours of sleep each night is considered ideal for most people. Ten hours of sleep a night isn't always "too much," but depending on the situation, it may indicate something. Ten hours may be typical if you're recuperating from a medical condition, rigorous exercise, stress, or sleep debt. But constantly requiring so much sleep might be a sign of poor sleep, depression, thyroid problems, or other illnesses. Although the exact cause is unknown, some research has linked oversleeping to higher health risks. The demand for extended sleep may result from schedule disturbance rather than a genuine need for sleep if you're using stimulants like modafinil or modvigil to treat tiredness or shift work.
