Caffeine is a natural stimulant most commonly found in coffee, tea, and various energy drinks. It works by blocking the action of adenosine, a brain chemical involved in sleep, which can lead to increased alertness and wakefulness. While caffeine can enhance focus and energy levels, its consumption, especially in the afternoon or evening, can negatively impact sleep quality. It can delay the onset of sleep, reduce total sleep time, and affect the depth of sleep, leading to less restorative rest. To improve sleep, it is often recommended to limit caffeine intake several hours before bedtime.
