Caffeine is a natural substance that stimulates the brain and nerves and activates the central nervous system. Frequent coffee and/or tea consumption has been shown to enhance short-term memory, alertness, and attention span. While the majority of people enjoy the "revved up" feeling that caffeine gives off, some people are caffeine-sensitive and feel jittery or ill after ingesting a dose. If you fall into the second group, you should either quit drinking coffee all together or cut back on your intake to match your tolerance level. Caffeine should be avoided for up to eight hours before bedtime if you experience insomnia or difficulties falling asleep (or omitted entirely). Tea and coffee may help you wake up and stay focused, but if you consume too much of it, it might make you more susceptible to migraines or irritable bowel movement (IBS).

Free radicals are produced when our body converts a particular food into energy. These compounds have the capacity to damage body cells and bring about a variety of diseases. Antioxidants that fight these free radicals are produced in part by both tea and coffee. Additionally, studies conducted throughout the years have linked coffee consumption to a lower incidence of Parkinson's illness. Although caffeine appears to be an influence, other chemicals may also be in play. For instance, decaffeinated coffee has been shown in some studies to protect against neurodegeneration in a Parkinson's disease model. Both tea and coffee include caffeine, which aids in the body's defense against Parkinson's disease. Additionally, studies have shown that caffeine not only safeguards the brain but also aids in the early detection of this brain illness.

Caffeine may, however, also have some adverse effects on female health in the days before menstruation. Many studies have shown that premenstrual women are more sensitive to the effects of coffee. In addition to raising jitteriness, anxiety, and irritability, caffeine may exacerbate PMS symptoms. If you identify with this, consider switching to decaffeinated or herbal teas at this point of your cycle.

Despite the health advantages of coffee and tea, consuming too much of them can cause anxiety, irritability, and difficulty falling asleep. Additionally, it may impair your capacity to retain calcium, which might cause bone fractures (calcium keeps bones strong). If you're unsure of how much is too much for you, see your doctor.
