Your cells eat themselves — and that's good

Autophagy (from Greek: 'self-eating') is the process where cells break down and recycle damaged components. It's your body's cleanup crew.

Fact

How it works

When autophagy is activated, a double membrane wraps around damaged proteins and organelles, forming an 'autophagosome.' This fuses with a lysosome, which digests the contents and recycles them into usable parts.

Autophagy only happens when you're sleeping.

Autophagy only happens during sleep
Autophagy is triggered by fasting, exercise, and cellular stress — not just sleep. Though sleep does support it!
Insight
