If you’ve lived your life on the idea that eight hours of sleep is ideal, then it might be time to rethink that. Researchers now say that middle-aged and older should use an optimal sleep time of seven hours. Any more or any less may leave you with poorer cognitive performance and mental health.at the end of April. In the study, the researchers dig deep into optimal sleep time and how it affects us. They examined data from almost 500,000 adults between the ages of 38-73 years old.
When analyzing the data, researchers from Fudan University in Chin, and the University of Cambridge found some surprising results. When looking at the data, the researchers found that seven hours provided improved cognitive performance compared to sleeping longer or less.
