Getting the right amount of sleep is crucial for maintaining a healthy heart, according to the latest research. A new study suggests that both too little and too much sleep can increase the risk of cardiovascular problems.
The Goldilocks Zone for Sleep
Scientists have identified a "Goldilocks zone" for sleep duration—neither too short nor too long—that appears to be most beneficial for heart health. The study found that adults who consistently sleep between 7 and 8 hours per night have the lowest risk of developing heart disease.
Risks of Poor Sleep Habits
Those who regularly sleep fewer than 6 hours or more than 9 hours may face:
- Higher blood pressure
- Increased inflammation
- Greater risk of arterial stiffness
- Higher likelihood of developing coronary artery disease
Why Sleep Matters for Your Heart
During sleep, your body performs critical maintenance functions that help regulate:
- Blood pressure
- Stress hormones
- Glucose metabolism
- Inflammatory responses
Chronic sleep deprivation disrupts these processes, potentially leading to long-term cardiovascular damage.
Tips for Better Sleep
To improve your sleep quality and protect your heart:
- Maintain a consistent sleep schedule
- Create a dark, quiet sleeping environment
- Avoid screens before bedtime
- Limit caffeine and alcohol consumption in the evening
The findings highlight the importance of prioritizing sleep as part of a heart-healthy lifestyle, alongside diet and exercise.
