There is nothing wrong with a nap from time to time, but experts warn that if you always feel tired and take naps all the time, it could be a sign of a larger health issue.
Researchers tested nappers and non-nappers and found people who napped more than an hour a day were 32 percent more likely to die early.
The frequent nappers had a greater risk of death by heart disease, cancer, and respiratory illness.
The researchers say that this does not prove that naps lead to death, but they believe it could be evidence of an undiagnosed health problem that causes someone to be tired.
Many experts say there are benefits to occasional napping.
They say that 30 minutes is best.
