A recent study published in the journal Nature highlights the crucial link between sleep patterns and biological ageing, suggesting that both insufficient and excessive sleep can accelerate ageing. Optimal sleep duration is identified as 6.5 to 7.5 hours per night, emphasizing sleep's role in health and longevity.
- 01The study analyzed health data from nearly 500,000 adults, revealing a 'U-shaped relationship' between sleep duration and biological ageing.
- 02Individuals sleeping less than 6 hours or more than 7.5 hours exhibited signs of accelerated biological ageing.
- 03Chronic sleep disruption leads to increased inflammation and vulnerability to chronic diseases, affecting immunity and cardiovascular health.
- 04Obstructive sleep apnoea (OSA) is a significant but often underdiagnosed condition in India, linked to various health risks.
- 05Experts recommend maintaining a fixed sleep schedule, avoiding screens before bed, and managing stress for better sleep quality.

A groundbreaking study published in the journal Nature has revealed a significant connection between sleep patterns and biological ageing. Researchers found that both insufficient sleep (less than 6 hours) and excessive sleep (more than 7.5 hours) can accelerate the ageing process, affecting major organs like the brain and heart. The optimal sleep duration for health and longevity is identified as approximately 6.5 to 7.5 hours per night. Poor sleep quality contributes to chronic inflammation and increases the risk of diseases such as hypertension, obesity, and heart disease. The study highlights the need for better sleep hygiene in modern lifestyles, which are often disrupted by screens and stress. Furthermore, obstructive sleep apnoea (OSA) remains a significant concern, often going undiagnosed and contributing to various health issues. Experts advocate for prioritizing sleep as a fundamental aspect of health, suggesting practices such as maintaining a consistent sleep schedule and managing stress effectively to promote restorative sleep and healthier ageing.
