Rest Assured: Your Guide to Sleep’s Role in a Healthy Heart

You can rest assured that one of the most impactful things you can do for your heart happens while you’re not even conscious. Sleep is a cornerstone of cardiovascular wellness. This guide will help you understand its vital role and provide actionable tips for improving your rest and, by extension, your heart health.
The core role of sleep is restoration. Each night, it provides a crucial opportunity for your heart and blood vessels to recover from the demands of the day. This happens via the “nocturnal dip,” a natural lowering of blood pressure and heart rate that reduces mechanical stress. Without this, your system is in a state of constant high alert, which leads to long-term damage.
Sleep also plays the role of a regulator. It helps balance a host of bodily functions critical to heart health. It keeps inflammation in check, preventing damage to your arteries. It regulates hormones that control appetite and blood sugar, which helps to prevent weight gain and diabetes—two major risk factors for heart disease.
To ensure your heart gets these benefits, prioritize sleep hygiene. Maintain a regular bedtime, even on weekends. Create a calm, dark environment by removing electronic gadgets and using blackout curtains. If you suspect a sleep disorder like sleep apnea (indicated by loud snoring or gasping), consult a doctor without delay. Making these changes can help you rest assured that you are actively protecting your heart.
