How much sleep needs an adult?

Most adults need between six to eight hours of sleep per night. While some individuals can function with as little as five hours, others might require up to nine or ten hours, especially growing kids, teenagers, or those recovering from illness. It's important to understand that these are general guidelines, and individual sleep needs can vary. Everyone should strive to find the amount and quality of sleep that works best for them, maintaining a fairly consistent sleep routine, aiming to sleep and wake up around the same time each day 1 2.

In episodes of the Huberman Lab, Andrew Huberman discusses the critical investment of sleep for mood and mental health, alongside the significance of its consistency. Maintaining a consistent sleep routine aids in the regulation of mood and ensures the optimal amounts of slow-wave (deep) sleep and rapid eye movement (REM) sleep 3.
