- Increase in cardiovascular events (e.g., myocardial infarction, stroke, heart failure) during winter, especially in Japan.
- Winter hypertension results from environmental factors and physiological responses, leading to higher morning blood pressure (BP) surge and variability.
- Thermosensitive hypertension: some individuals show significant BP changes due to cold exposure.
- Winter mornings see a combination of cold stress and arousal response, increasing BP, BP variability, and morning BP surge.
- Highest cardiovascular event risk occurs during early winter mornings due to overlapping factors.
- Management strategies include optimizing living conditions, lifestyle changes, home BP monitoring, and digital therapeutics.
- Post-awakening period is critical due to cold exposure, low indoor temperature, and increased physical activity.
- Comprehensive BP management should consider variability, chronobiology, and environment, not just absolute BP levels.
