Exercise Cuts Sleep Apnea Risk, Landmark Study Reveals

A new study has found that higher levels of physical activity reduce the risk of obstructive sleep apnea (OSA). The research, which tracked nearly 130,000 people in the U.S. for up to 18 years, also showed that spending less time sitting or watching TV lowers the likelihood of developing the condition. This is the first long-term study to examine both exercise and sedentary habits in relation to OSA risk.

The study followed around 130,000 men and women across the U.S. over a period of 10 to 18 years. Participants provided self-reported data on their physical activity, sedentary behaviours, and any OSA diagnoses. Researchers focused on recreational exercise and specific inactive habits, such as sitting for long periods or watching television.

Both moderate and vigorous physical activity were strongly linked to a lower risk of OSA. The findings also revealed that people who spent fewer hours sitting or watching TV had a reduced chance of developing the sleep disorder. The protective effects were particularly noticeable among women, adults over 65, and individuals with a body mass index (BMI) of 25 kg/m² or higher. Due to the large sample size and detailed assessments, investigators are now urging doctors to encourage physical activity as a way to help prevent OSA. The study highlights the importance of staying active and minimising prolonged sitting to improve sleep health.

The research provides clear evidence that regular exercise and less sedentary time can lower OSA risk. Physicians may now have stronger grounds to recommend physical activity, especially for older adults, women, and those with higher BMI. The findings could influence future guidelines on managing and preventing sleep-related breathing disorders.
