This audiobook is narrated by a digital voice.

Eight hours. Everyone knows the rule. But what if it’s the wrong question?

How much sleep do you really need — and what actually happens when you consistently get less?

How Much Sleep Do You Really Need? cuts through the myths and explores what sleep science actually tells us about sleep duration, sleep quality, sleep deprivation, sleep debt, recovery, and individual sleep needs.

Discover why the famous eight-hour rule is more complicated than it sounds, why you may not notice how sleep-deprived you’ve become, and what your energy, attention, mood, and performance can reveal about the sleep you’re getting.

You’ll explore questions such as:

• Is eight hours really the ideal amount of sleep?

• Can you train yourself to need less sleep?

• Does lost sleep accumulate as sleep debt?

• Can you catch up on sleep later?

• Why do some people seem to function on less?

• How can you tell whether you’re actually getting enough?

No endless wellness advice. No obsession with the perfect bedtime routine. Just a concise, accessible journey through the science of how much sleep humans actually need.

Perfect for curious listeners who want to understand their sleep, without spending hours doing it.
