Caffeine, a compound naturally present in various beverages such as coffee and tea, as well as in certain foods, has multiple functions and benefits. Caffeine can stimulate the sympathetic nervous system, enhance mental alertness, help alleviate fatigue, and promote wakefulness. It can also boost metabolic rate, accelerate fat oxidation and energy expenditure, thus providing some supportive effects for weight management and weight loss. Additionally, caffeine has a diuretic effect, increasing urine output and helping eliminate excess water and waste from the body. Furthermore, by influencing neurotransmitters—for instance, blocking adenosine receptors—caffeine can exert analgesic effects and help relieve symptoms such as migraines and muscle pain. Caffeine intake should be moderate, as excessive consumption may lead to adverse reactions such as palpitations and insomnia. While enjoying the benefits of caffeine, it is important to monitor intake. If any discomfort occurs, prompt medical attention is recommended.
