Caffeine and Sleep
Caffeine can significantly disrupt sleep quality, particularly by reducing deep, non-REM sleep in the first hours of the night. Even a single cup of coffee consumed in the evening can decrease deep sleep by about 30%, equivalent to aging your sleep by 12 to 14 years. Many may feel they sleep well after caffeine, but they often lack awareness of the true quality of their deep sleep, leading to potential long-term effects on their restfulness.In this clip
