Morning Exercise Cuts Heart Rhythm Disorder Risk
20 Jan
Summary
- Morning workouts reduce atrial fibrillation risk by 21%.
- Exercising between 6am and noon may prolong blood pressure dips.
- Any exercise is beneficial, even short bursts throughout the day.
New research suggests that exercising in the morning, specifically between 6am and noon, can reduce the risk of developing atrial fibrillation (AF) by 21%. This heart rhythm disorder, prevalent in the UK, is a significant cause of stroke. Afternoon or evening workouts showed a lesser risk reduction of approximately 14%.
The protective effect of morning exercise is thought to be linked to its potential to extend the natural dip in blood pressure that occurs overnight. This prolonged reduction in blood pressure may offer greater protection against AF, a condition characterized by an irregular heartbeat.
While morning exercise shows particular benefits, cardiologists emphasize that any form of regular physical activity is crucial for heart health and combating high blood pressure, a known risk factor for AF. Simple actions like standing up and moving throughout the day are also encouraged.
Further studies also highlight benefits of exercise timing for other health aspects. For instance, some research indicates morning runs may aid weight loss by increasing fat burn due to overnight fasting. Conversely, evening exercise, like short bursts of activity every half hour from 5pm, has been shown to improve sleep quality.
