Insights by Echo AI

Caffeine, the world's most consumed psychoactive substance, impacts individuals differently. While some people remain alert after consuming it, others can fall asleep soon afterward. This disparity is attributed to genetic factors, liver metabolism speed, and lifestyle habits such as smoking. Specialists advise avoiding caffeine close to bedtime, and pregnant women should limit their intake. Regular consumption builds tolerance, and sensitivity may return after a break.
