Habits that change your rhythm.

Alcohol is one of the most consistent and modifiable triggers for atrial fibrillation. Even moderate drinking promotes AFib, and reducing or stopping is one of the highest-yield lifestyle changes our patients can make.

Caffeine is much less of an AFib trigger than its reputation suggests. Other stimulants — energy drinks, pre-workouts, decongestants, certain ADHD medications, and recreational stimulants — are a different story.

Regular moderate exercise lowers the risk of atrial fibrillation and improves outcomes once it develops. Extreme endurance training is a separate story. Most patients should be doing more, not less.

Apple Watches, Kardia devices, Fitbits, and continuous patch monitors have changed how we manage AFib. They are excellent at catching episodes — but they also raise real questions about over-detection and anxiety.

Obstructive sleep apnea is one of the strongest under-recognized drivers of atrial fibrillation. Diagnosing and treating it — usually with CPAP — meaningfully reduces AFib recurrence and improves outcomes after ablation.

Excess body weight directly promotes atrial fibrillation. Sustained, modest weight loss reduces AFib burden, improves ablation success, and sometimes reverses the rhythm entirely.
