The optimum amount of sleep is not too little but not too much – at least in middle and old age.

New research has found that around seven hours of sleep is the ideal night’s rest, with insufficient and excessive sleep associated with a reduced ability to pay attention, remember and learn new things, solve problems and make decisions.

Seven hours of slumber was also found to be linked with better mental health, with people experiencing more symptoms of anxiety and depression and worse overall well-being if they reported sleeping for longer or shorter stints.

“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,” Jianfeng Feng, a professor at China’s Fudan University and an author of the study published in the scientific journal Nature Aging, said in a statement.

“But the reasons why older people have poorer sleep appear to be complex, influenced by a combination of our genetic makeup and the structure of our brains.”

It’s well known that getting a good night’s sleep becomes more difficult as we age, but the underlying biology for why this happens has remained poorly understood.

A team of US scientists has now identified how the brain circuitry involved in regulating sleepfulness and wakefulness degrades over time in mice, which they say paves the way for better medicines in humans.

“More than half of people 65 and older complain about the quality of sleep,” Stanford University professor Luis de Lecea, who co-authored a study about the finding published Thursday in Science, told AFP.

Scientists may have identified the perfect bedtime to protect your heart — 10 p.m. to 11 p.m.

Per NBC News, scientists recently reviewed data from 88,000 adults who tracked their sleep patterns for six years.

They found that there was a 12% greater risk for heart disease in those who went to sleep from 11 p.m. to 11:59 p.m. There was a 25% higher risk of developing the cardiovascular disease for those who fell asleep past midnight. There was a 24% decreased risk in those who fell asleep before 10 p.m.

Nicknamed the Queen of Dreams by her peers, Dr. Cartwright studied the role of dreaming in divorce-induced depression, worked with sleep apnea patients and their frustrated spouses, and helped open one of the first sleep disorder clinics.

She died at 98 on Jan. 15 at her home in Chicago. Her daughter, Carolyn Cartwright, said the cause was a heart attack.
