Sudden Wake-Ups Trigger Heart Attacks
9 Dec
Summary
- Morning hours (6-10 am) see most heart attacks in young people.
- Erratic sleep and work pressure disrupt the body's natural 24-hour clock.
- Immediate phone use upon waking heightens heart attack risk.
Early morning hours, specifically between 6 am and 10 am, are a critical period for heart health, with a significant number of heart attacks occurring in younger individuals during this time. This heightened risk is often linked to a disruption in the body's natural 24-hour internal clock, known as the circadian rhythm, which governs sleep-wake cycles and hormone regulation.
Upon waking, the body naturally releases stress hormones like cortisol and adrenaline, preparing for the day. However, immediate engagement with stimulating content, such as work emails or news alerts via cellphones, can prematurely activate the 'fight or flight' response. This, combined with poor sleep, causes these hormones to remain elevated, constricting arteries and disrupting blood flow, especially when coupled with other stressors like immediate workouts.
To minimize morning heart attack risk, experts recommend gradually waking up, hydrating with water, and avoiding cellphones for at least 30 minutes. Long-term strategies include ensuring 7-8 hours of sleep, maintaining a balanced diet, regular moderate exercise, and avoiding smoking and excessive alcohol. Waking up peacefully, rather than to immediate digital distractions, is crucial for cardiovascular well-being.
