Short Sleep Duration Under Seven Hours Linked to Reduced Lifespan, US Study Finds

The Key to Living Longer

According to НВ — Техно: Recent research suggests that how long you sleep might outweigh diet and exercise in determining lifespan. Experts from Oregon Health & Science University examined survey data collected in the United States between 2019 and 2025. Their findings indicate that sleeping less than seven hours each night is strongly associated with a shorter expected lifespan.

Why Sleep Matters for Longevity

This study highlights the critical role of sleep in extending life expectancy, potentially even more than dietary habits or physical activity levels. It's important to note, however, that this research is observational and does not establish a direct cause-and-effect relationship between short sleep and lifespan. Other important factors were also considered in the analysis, including:

• physical activity levels
• employment status
• educational background
• smoking habits
• obesity
• diabetes

In some models, smoking, obesity, and diabetes showed a stronger impact on lifespan than insufficient sleep.

Sleep disturbances are also linked to obesity and diabetes, reinforcing the importance of adequate sleep for overall health. Health experts recommend adults aim for at least seven hours of sleep per night, with seven to nine hours considered optimal.

“People should try to get between seven and nine hours of sleep whenever possible.” - Andrew McGill

These insights emphasize the need to prioritize sleep as a vital component of a healthy lifestyle. Public health initiatives should focus on promoting sufficient sleep alongside balanced nutrition and regular exercise to improve life expectancy and well-being.

In addition to the findings on sleep duration, recent research from China suggests that extended REM sleep may significantly reduce the risk of various diseases. This highlights the multifaceted nature of sleep's impact on health, reinforcing the argument that prioritizing quality sleep is essential for longevity and overall well-being.
