Human 101
Holding your breath too long lowers oxygen and raises carbon dioxide in your blood. This leads to diaphragm spasms, dizziness, and eventually loss of consciousness if pushed too far. Your body’s urge to breathe is actually triggered by CO₂ buildup, not oxygen shortage.

Ever wondered why the sky is blue? It’s all thanks to Rayleigh scattering — the way Earth’s atmosphere scatters sunlight. Short wavelengths like blue scatter more than red, so our eyes see a bright blue sky. At sunrise and sunset, the sky turns red and orange because longer wavelengths take over.
