How does the amount of sleep you get impact your health?

Sleep isn't just about rest: it's a fundamental regulator of health. A recent meta-analysis of 79 cohort studies confirmed that both sleeping too little and sleeping too much can increase the risk of mortality.

Sleeping less than 7 hours per night increases the risk of death by approximately 14%, while sleeping 9 hours or more increases it by 34%. The research identified the optimal range to be 7 to 8 hours per night, as it greatly reduces risks. Furthermore, prolonged sleep was shown to be especially harmful in women.

This evidence demonstrates that maintaining a balance in sleep hours is key to preventive and curative health. At WaveMed Clínica Integral, we promote healthy lifestyle habits such as good sleep, along with modern and natural therapies, because investing in your health today guarantees a better future for you and your family.
