“Less Than 3 Hours of Exercise per Week Can Offset Sleep Deprivation Risk: Study”

Office workers live under a lot of pressure, work is busy, and there is not enough time for sleep and rest. How can there be time for exercise? However, some studies now point out that if you only need less than 3 hours of exercise per week, your mental and physical strength will improve, and you can also make up for the short-lived risk caused by lack of sleep.

The research team led by Dr. Zhang Jihui, director of the Sleep Medicine Center of the Affiliated Hospital of Guangzhou Medical University in China, followed more than 90,000 adults and found that people who exercise regularly will not increase the risk of death even if they sleep less. Counteracts the side effects of sleep deprivation.

Exercise offsets sleep deprivation risk

The study used more than 90,000 adults aged 40 to 73 from the UK Biobank who wore tracking wristbands for a week between 2013 and 2015, and analyzed the relationship between sleep and exercise on the body .

First they divided people into short (less than 6 hours), normal (6 to 8 hours) or long (more than 8 hours) sleep duration per night; while total physical activity was also divided into low, medium and high groups Only moderate exercise meets the vigorous exercise standards recommended by the World Health Organization.

The results showed that those who slept too much or not enough and did not get enough exercise (such as below the recommended 150 minutes of exercise per week) were more likely to live shorter or die from cancer and heart disease.Those who exercised more than 150 minutes a week did not increase their risk of death even if they slept less than 6 hours a night.

Exercise and rest should choose exercise first

Zhang Jihui also pointed out in an interview with foreign media that from this study, it can be seen that the impact of exercise on inflammation, metabolism and the sympathetic nervous system are all closely related to heart health.“So, to some extent, if you have free time, people should trade rest for exercise and exercise.”The results were published in the European Journal of Preventive Cardiology.

But Dr. Bo-Huei Huang, an epidemiologist and sleep researcher at the University of Technology Sydney in Australia, said the amount and intensity of exercise each person needs will depend on many factors, including age, whether someone is pregnant or has a chronic disease or disability.

For example, there is no standard for the sleep goals required by different ages. Young people may need more sleep than old people. However, studies like this compare the two important health factors of “exercise” and “sleep”. It will encourage people to pay more attention to their living habits, and neither should be neglected.
