What is Autophagy?
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.
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.
True or False
Autophagy only happens when you're sleeping.

Why it matters for aging
As we age, autophagy slows down. Damaged proteins accumulate, cells malfunction, and disease risk rises. Boosting autophagy is a core strategy in longevity science.
