Study: Over 9 Hours of Sleep Linked to Early Death Risk
A new study looked at how much sleep is healthy.
They found that sleeping too much, over nine hours, might be linked to a higher chance of dying early.
The study looked at many other studies.
People who slept less than seven hours also had a higher risk.
The study suggests that if you sleep too much, it could mean you have other health problems.
Experts say that if you regularly sleep for more than nine hours and still feel tired, you should talk to a doctor, since it may be a sign of a deeper health issue.
A study indicates that sleeping over nine hours may increase the risk of early death by 34%.
The study analyzed findings from 79 studies, tracking participants' sleep habits for over a year.
People sleeping less than seven hours had a 14% higher risk of dying compared to those sleeping seven to eight hours.
Poor sleep quality was linked to a 44% higher risk of developing heart diseases.
Excessive sleep may be a symptom of underlying health issues like depression or metabolic problems.
