How much sleep do you really need?

You know you need to get enough sleep, but the question remains: How much is enough? Sleep scientist Matt Walker tells us the recommended amount for adults and explains why it's necessary for your long-term health.

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.
