7 hours of sleep is ideal for many adults, study finds
Don’t sleep on this recent study. Middle-age and older people should sleep seven hours each night for ideal rest and recovery, according to a study published last month.
The research, published in Nature Aging, studied nearly 500,000 people between the ages of 38 and 73.
“While we can’t say conclusively that too little or too much sleep causes cognitive problems, our analysis looking at individuals over a longer period of time appears to support this idea,” co-author Jianfeng Feng said in a statement.
Researchers found that people who got exactly seven hours of sleep on a consistent basis saw better mental health, better memory, increased ability to pay attention and fewer symptoms of depression. Previous studies have also suggested that seven hours is the ideal amount of sleep.
The latest study was conducted using the U.K.’s Biobank program and completed by researchers from the U.K. and China. It relied on participants reporting their own nights of sleep.
