Although obesity increases the risk of heart disease, it has now been found that such people have a much higher risk of heart disease and diabetes if they are accustomed to waking up late at night.
This was revealed in a medical study in Italy. The study, by the University of Naples Federico II, compared the sleep habits and illnesses of 172 middle-aged people.
Research has shown that sleeping and waking routines are the most important for humans. Six out of 10 people in the study were accustomed to waking up in the morning, while 13 percent went to bed at night. The rest of the people were somewhere in between.
All three groups in the study had similar weights, but those who stayed up late were more likely to burn more calories at night and were more likely to engage in unhealthy habits such as smoking and not exercising. All of these factors increase the risk of medical problems.
“The study found that 30 percent of those who woke up in the morning had heart disease, but the rate was about 55 percent of those who stayed up late.”
Similarly, the risk of type 2 diabetes was found in 9% of those who went to bed early and 37% of those who stayed up late. The results of the third group were similar to those of the early morning group.
Older research reports estimated that people who stay up late had 1.3 times higher risk of high blood pressure and cholesterol than those who woke up early.
The researcher said, “overall, people who stay up late have a higher risk of heart disease and type 2 diabetes than others.” He said that the best way to avoid this is to control your body weight, keeping in mind your sleeping habits.
He added, “unfortunately, it is not easy for people to change their sleep, diet, and activity routines and they have to work harder to reset the body clock.”
Earlier in 2020, research from the University of Leicestershire in the UK and the University of South Australia in Australia found that there was a link between people’s sleep habits and type 2 diabetes.
Research has found that people who wake up late at night and wake up late in the morning have a much slower lifestyle or, say, less physical activity, which increases the risk to their health.
Type 2 diabetes is usually the result of overweight and a sedentary lifestyle that currently affects one in 11 adults worldwide. Experts say that people’s sleep habits affect physical activity and understanding this can help diabetics keep their condition stable.
He said, “At the moment, a large number of diabetics need help so that they can lead a healthy lifestyle while maintaining a dynamic lifestyle.”
He added that this is especially important for those who prefer to sleep late at night and wake up during the day, as they tend to exercise 56% less than those who wake up in the morning.
