Caffeine can temporarily boost energy, but some individuals may experience intolerance with various symptoms.
Headaches, caused by dehydration or caffeine withdrawal, are common, along with a dry, flaky scalp from caffeine-induced dehydration. Excess caffeine can lead to restless legs, especially at night, due to overstimulation of the nervous system.
Midday energy crashes, stomach issues like bloating or cramps, and constant thirst from caffeine’s diuretic effects are also common. Other symptoms include a greenish coating on the tongue, swelling, and increased anxiety from nervous system overstimulation. High caffeine intake can also cause muscle twitches due to electrolyte imbalances.
Reducing caffeine intake may help improve these symptoms and overall health.
