Bannister Wolfe: Bannister here, let's continue to Think Healthy. Today we talk about the chances of getting dementia. Recently, Nature Communications published a major study.
Basically, the study found that people over the age of 50--who slept less than six hours per night--had a HIGHER RISK of developing dementia--when it was compared to people who slept around 7 hours per night!
Doctor Puja: Hi Bannister! The study looked at people over a 25 period. And it found that the risk of dementia went up for all sorts of people. So, look, the study suggests that when we sleep less, many functions of our body are disrupted. And THIS increases the chances of getting dementia.
BUT, this does not mean that if you sleep less, you're going to get dementia.
are extremely complicatedand many times you're going to find that there are more than one contributing factor for a disease.
Doctor Puja: So, sleep more if you can! Rest more if you can! But... don't get yourself into panic if you're sleeping less than 7 hours a night. As always, talk to your health care provider!
Bannister Wolfe: And, that's Doctor Puja.
