Middle age people are at higher risk to Dementia:- If you are sleeping for less than six hours in the night, there would be a risk for dementia when you are in your 50s and 60s. This is revealed as per the study that was conducted on 8000 British adults. The research was based on the data that was collected from a long-running survey which kept a line between your sleep and dementia in the people as per their age. The study got published in the journal Nature Communications and it clearly indicated that the people who slept for less than six hours in the night are at a higher risk to dementia. The normal sleep that is expected to keep healthy is seven hours. All those who are addicted to short sleeping patterns are at a risk to dementia in the age between 50 and 70. This is irrespective of cardiometabolic or mental health issues.
