What is your "sleeping age"? Ah, yeah. I'm the usual careless. First I should explain (unless you already know) what is meant by "sleeping age". This is an estimate that roughly indicates a person's health-related age, based on their sleep quality.
For example: if a person is 45 years old but sleeps badly, his "sleeping age" is probably 58 years old. Not very well.
Why? While we sleep, our brains "execute" a set program. It "clears" the memory, restores and restores the body. Heart rate and breathing also change during sleep. And changes in these parameters (hence changes in sleep quality) could be used as a warning sign of a health problem.
A recently published study (you can find it at the bottom of the article) has attributed great importance to the quality of sleep.
The strongest predictor of mortality
Emmanuel Mignot and his team are currently working with scientists from theHarvard University to create a system capable of estimating the age of sleep, and with this also the mortality of a patient. Studies already started on a total of 12.000 patients have provided the first interesting data. Each "booklet" analyzes a patient's sleep characteristics such as chin and leg movement, breathing and heart rate. Studies already planned on as many as 250.000 new dossiers will help collect an impressive amount of data, and machine learning will do the rest.
"Our main finding from the data already analyzed was that sleep fragmentation (waking up multiple times during the night for less than a minute without remembering it) is the strongest predictor of mortality," says Mignot. "However, although we see a correlation, it is not yet clear how this circumstance contributes to mortality. The figure, for example, differs from that of a person realizing that he has woken up, which happens during sleep disorders such as the 'insomnia".
Shorten the age of sleep, extend the age of life
On this the researcher has very clear ideas, as well as an enviable common sense. There are very simple things we can do to improve our sleeping age: for example, expose yourself to sunlight for enough hours.
Or get regular exercise, but not too close to the time you go to sleep. Again, don't drink alcohol or caffeine after a certain time, and avoid heavy night meals. It looks like an episode of Studio Aperto: all that's missing is "drinking a lot and not going out during the hottest hours".
Anyway, the study you can find it here.
I have given you the news.
Sleep on it.
