A large U.S. study found that people who regularly get less than 7 hours of sleep tend to have a shorter life expectancy, even more strongly than poor diet or lack of exercise. Only smoking showed a greater impact on lifespan.
Sleep plays a vital role in:
• Heart health
• Immune function
• Brain repair
• Metabolic balance
This research suggests prioritizing 7–9 hours of quality sleep may be one of the most powerful things you can do for long-term health
