你需要多少睡眠時間？

你知道你需要獲得足夠的睡眠，但問題來了：多少才足夠？睡眠科學家馬特·沃克 (Matt Walker) 告訴我們成人應該睡多久，並解釋睡眠對於長期健康的重要性。

Most adults need seven to nine hours of sleep each night for optimal long-term health. Falling below this range increases mortality risk, according to large epidemiological studies and the CDC. Strikingly, sleeping more than nine hours is also linked to higher mortality, often due to underlying illness or poor quality sleep. Modern lifestyles encourage sleep deprivation, yet consistently prioritizing sufficient rest is vital for wellbeing.
