Sleeping enough is excellent for health, ensuring we have the energy to work throughout the day, as is widely known. In a recent study, scientists also revealed that sufficient and quality sleep can potentially help extend our lifespan.

For women, sufficient and good-quality sleep can potentially increase lifespan by 2 years. For men, this number is even higher, reaching up to 5 years. Along with this, the overall health of both genders is better compared to groups with insufficient sleep or poor sleep quality. For the younger generation, having a habit of good sleep can also reduce the risk of premature death. According to this study, not having a good sleep habit increases the risk of death by 8% due to any cause.

The secret to a 'great' night's sleep lies in 5 key factors:

- ensuring a restful duration of 7 to 8 hours,

- experiencing minimal difficulty falling asleep (less than twice a week is ideal)

- avoid struggling to stay awake (less than twice a week is acceptable)

- refrain from using sleep-inducing medications

- wake up feeling refreshed and invigorated (at least 5 times a week is ideal)

Research data drawn from a national health survey in the United States spanning from 2013 to 2018, involving over 172,000 individuals aged 50 and above. Over the course of this 4-year period, nearly 8,700 respondents passed away. Approximately 30% due to cardiovascular issues, 24% from cancer, and the remaining 46% attributed to various other reasons.

On a scale of 0-5, with 5 being the best, those consistently rating themselves a 5 experienced a 30% lower risk of death from other causes, a 21% reduction in cardiovascular mortality, a 19% decrease in cancer-related deaths, and a 40% decline in other reasons beyond the mentioned ailments. The extension of lifespan and reduced mortality risk typically commence from the age of 30 onwards. For the younger generation, scientists suggest that cultivating good sleep habits could contribute to an extended lifespan.
