Why shouldn't we sleep upside down?

You shouldn't sleep upside down because it dangerously redirects blood flow, causing it to pool in your head and increase pressure in your brain, eyes, and skull, which can lead to serious complications, including ruptured blood vessels, brain hemorrhages, and heart problems, with even short periods being risky and long periods potentially fatal; your body is designed for gravity to assist circulation, and being inverted fights this system, making it hard for blood to return from the head.

What happens if you lay upside down for 30 minutes?

Hanging upside down for 30 minutes causes blood to rush to your head, increasing pressure in the brain, eyes, and blood vessels, leading to headaches, dizziness, vision changes, and potential brain hemorrhage; your heart works harder to pump blood against gravity, organs compress your lungs, making breathing harder, and while short inversions (like 3 mins) are used in therapy, prolonged hanging for 30 mins is very risky, potentially causing serious issues like asphyxiation or heart strain, and you should consult a doctor before attempting inversion for health reasons.
