Context:

New research sheds light on how low-intensity, low-impact exercises such as yoga, tai chi, and walking or jogging can help alleviate insomnia symptoms and improve sleep quality. A meta-analysis of 22 randomized clinical trials reveals these exercises not only help individuals fall asleep faster but also extend sleep duration and reduce awakenings. Cognitive behavioral therapy (CBT) remains the first-line treatment for insomnia, but combining it with physical activity might provide more comprehensive benefits. The study emphasizes the need for further research to standardize exercise regimens and explore additional non-pharmaceutical treatments. Patients are encouraged to consult with healthcare providers before starting any new exercise routine and to gradually increase the intensity and frequency of their activity based on their body's response.

Dive Deeper:

• The meta-analysis evaluated 22 randomized clinical trials, focusing on non-pharmaceutical insomnia treatments which included various exercise regimens, acupuncture, massage, and cognitive behavioral therapy.

• Yoga, tai chi, and walking or jogging were identified as the most effective exercises in promoting better sleep by increasing sleep duration and reducing nighttime awakenings.

• Yoga sessions, lasting 45 to 60 minutes and conducted two to six times per week over one to four months, significantly increased sleep duration by nearly two hours per night and decreased waking instances by an hour.

• Tai chi, practiced two to three times weekly for 45 to 60 minutes over several months, enhanced sleep duration by over 50 minutes and lowered the time spent awake by more than 30 minutes.

• Walking or jogging, performed three to five times a week for 30 to 75 minutes over three to six months, demonstrated a reduction in insomnia symptoms through increased energy expenditure and improved mood.

• Dr. Shalini Paruthi emphasizes that while exercise is beneficial, it should complement cognitive behavioral therapy, which remains the primary treatment due to its lasting benefits in adjusting sleep-related thoughts and behaviors.

• Timing of exercise is crucial; activities earlier in the day can enhance alertness while intense workouts near bedtime may disrupt the ability to fall asleep, highlighting the importance of sustainable and tailored exercise regimens for each individual.
