Too Much Sleep Can Also Be Harmful: Study of 18,000 Adults

People often assume that sleeping for a long time is good for them.

However, research has shown that sleeping for too long after middle age may not be good for your health.

This study was published in npj Aging, a Nature partner journal.

A joint research team, including Monash University in Australia, tracked about 18,000 Chinese adults aged 45 and older for about nine years. They found that people who slept for more than nine hours a day had a 1.45 times higher risk of frailty compared to those who slept for 7 to 9 hours.

For those who slept less than 7 hours, the risk was more than twice as high.

The research team suggested 7 to 8 hours a day as the optimal sleep duration.

However, this sleep data was based on self-reported information.

They also explained that long sleep itself could possibly be due to existing health problems.

Still, we hope everyone understands that sleep is of the utmost importance for health.
