Caffeine, commonly found in coffee but also present in tea, cocoa, and guarana, is a natural chemical that has significant effects on our daily lives. It wakes up our nervous system, helping us fight off drowsiness, and boosting our heart and metabolism. While these effects can be positive in moderation, too much caffeine can lead to overstimulation, making us irritable and increasing the risk of developing tinnitus.
According to studies, the average daily intake of caffeine in adults is appoximately 320 mg. However, the recommended dose is a maximum of 200 mg. Consuming more than the suggested amount can have harmful effects, including:
