Study warns that irregular sleep time can have a huge impact on heart health

A new study by the National Institutes of Health (NIH) warns that people should control their sleep times if they want to help protect their heart health from cardiovascular disease,media reported. It is reported that part of the funding for the study is provided by the National Heart, Lung and Blood Institute of the National Institutes of Health. The study found that irregular sleep is an independent risk factor for future heart disease.

Irregular sleep time

Past studies have shown that adequate, healthy sleep has many protections and benefits for health. Similarly, studies have found that poor sleep quality, too little sleep, and similar sleep disruptioncan can lead to a range of health problems over time, including immediate illnesses such as high blood pressure and long-term problems such as Alzheimer’s and increased cancer risk.

The latest study, published in Journal of The American College of America, looks at whether irregular sleep — not just poor or lack of sleep — can also be a health risk factor. Unstable sleep schedules mean that people can’t go to bed and get up at the same time every morning and at night.

Long-term research

The study involved nearly 2,000 adults between the ages of 45 and 84 who did not have heart disease at the start of the study. They participated in a multiracial study of atherosclerosis (MESA);

To facilitate the collection of sleep-related data on participants, the researchers wore smartwatch-like devices on their wrists while they slept. In addition, as part of the study, each participant was asked a “comprehensive sleep study” at home.


After five years of follow-up, the researchers found that 111 people had cardiovascular disease. According to the data, people who slept the most irregularly were about twice as likely to develop the disease as those who slept on time and got up on time.

This increase dissonality is “intense” after adjustments were made to other potential factors such as obstructive sleep apnea. Minority participants were more affected than white participants, though the study found no significant gender differences.
