Study revealed that people over 50 are more likely to develop chronic diseases when sleeping poorly; understand

Sleep, in addition to being a basic need, also brings a number of health benefits. This is because, during sleep, the body produces hormones and synthesizes proteins that act in different ways in the body, such as controlling satiety and mood.

When the time to rest is shorter than recommended, in addition to feeling tired, it is possible that there is a risk of developing some diseases – especially in people over 50 years old.



That’s what the study concluded. PLoS Medicine, made in the UK. When comparing individuals over 50 years old who sleep more than five hours a night with those who rest for a shorter period, it was revealed that the latter group is more likely to develop chronic diseases as they age.

How the search was done

The survey was conducted with 8,000 civil servants and lasted two decades. Volunteers answered the question, “How many hours of sleep do you get on average per night during the week?” and, in some cases, had a wristwatch that helped monitor sleep.

Among the diseases observed by the researchers were diabetes, cancer, Parkinson’s, arthritis, depression, chronic kidney disease and cardiovascular conditions.

The results showed that, in the group studied from 50 years of age, the chance of developing chronic diseases was 30% higher when sleeping less than five hours a day, compared to those who slept seven hours.

The risk for increased diagnosis of the conditions was also higher with age. Over the age of 60, the probability was 32%, while at age 70, the odds rose to 40%. The study also revealed a higher risk of death in the group with the shortest sleep.

However, due to the limitations of the research – since only a third of the participants were women – more details need to be analyzed in order to understand the results obtained.

sleep benefits

On average, it is recommended that adults sleep between six to eight hours a night, uninterrupted. This time is considered ideal for the metabolism to remain organized and balanced.

  • Memory strengthening;
