Sleep is not merely a period of rest; it's a fundamental component of cardiovascular wellness. Recognising this, the American Heart Association (AHA) updated its cardiovascular health checklist in 2022, expanding from "Life's Simple 7" to "Life's Essential 8" to include sleep as a critical factor in heart health.

Understanding the Impact of Sleep on the Heart

Adequate sleep—defined as 7 to 9 hours per night for adults—is essential for maintaining optimal cardiovascular function. Insufficient or poor quality sleep has been linked to several heart related issues, including:

  • Elevated Blood Pressure: Lack of sleep can lead to hypertension, a major risk factor for heart disease.

  • Increased Inflammation: Sleep deprivation may cause systemic inflammation, contributing to atherosclerosis.

  • Impaired Glucose Metabolism: Poor sleep affects insulin sensitivity, increasing the risk of type 2 diabetes and heart disease.

  • Obesity: Sleep loss can disrupt hormones that regulate appetite, leading to weight gain and increased cardiac strain.

These factors collectively strain the cardiovascular system, underscoring the importance of prioritising restful sleep.

The AHA's Life's Essential 8 and Sleep

The AHA's inclusion of sleep in its Life's Essential 8 emphasises its significance alongside other health behaviours and factors such as diet, physical activity, and blood pressure management. This comprehensive approach acknowledges that sleep quality and duration are integral to cardiovascular health. 

Practical Steps for Heart Healthy Sleep

To support cardiovascular health through better sleep:

  • Maintain a Regular Sleep Schedule: Go to bed and wake up at the same times daily.

  • Create a Restful Environment: Keep your bedroom dark, quiet, and cool.

  • Limit Screen Time Before Bed: Avoid electronic devices at least an hour before sleeping.

  • Watch Your Diet: Avoid heavy meals, caffeine, and alcohol close to bedtime.

  • Stay Active: Regular physical activity can promote better sleep quality.

Conclusion

Prioritising sleep is not just about feeling rested—it’s a vital component of heart health. By focusing on sleep quality and consistency, individuals can take proactive steps toward cardiovascular wellness.
