Why is sleep important?

It’s clear from my precursor article, Understanding The Basics Of Sleep, that even mild insomnia can result in very serious consequences.

A lack of quality sleep shortens your life, reduces the quality of your life and, as Giacomo found out, can even kill you!

What are the benefits of sleep?

There isn’t a single outlying reason for why we sleep; in fact, scientists are now starting to prove that there are many benefits.

Each stage of sleep offers a different form of benefits; for example, sleep spindles in stage 2 aid memory consolidation and learning, whilst deep sleep in stages 3 and 4 supports recovery and repair.

This makes it important for you to complete a full night of sleep cycles to obtain the full benefit.

If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary process has ever made.
