What is the purpose of yawning for the body?

definition
"Yawning is the body's way of whispering that it needs rest, a reminder to honor the rhythms of life and embrace the stillness within."
According to Osho, yawning is a mechanical reflex that occurs as sleep approaches: breathing slows, carbon dioxide builds up, and—when we resist sleeping—the body expels this CO2 with a sudden wide-mouthed breath, drawing in fresh oxygen. Yawning thus momentarily counteracts drowsiness and resets the gas balance, signaling that rest is needed and helping maintain wakefulness if we insist on staying up.
When you’re sleepy but keep yourself awake, a yawn dumps extra CO2 and pulls in oxygen to give you a brief wake-up signal.
Why this matters practically
- Treat yawns as a cue to stop forcing wakefulness and go to bed.
- If you must stay up, get fresh air or breathe deeply to rebalance oxygen–CO2.
- Keep rooms ventilated at night to avoid excessive carbon dioxide and improve sleep.
