However, some people feel dizzy, lightheaded, or experience dropping blood pressure after drinking coffee. Experts believe that this phenomenon may stem from many different causes.
Caffeine often causes high blood pressure in the short term, especially in people who rarely use coffee. However, the reaction to caffeine is not the same in each person and may vary depending on the body.
One of the causes that can lead to hypotension is dehydration. Caffeine has a mild diuretic effect, causing the body to excrete more water. If you drink coffee but do not supplement enough water, especially in hot weather or after exercising a lot, circulatory volume may decrease, thereby causing blood pressure to drop.
In addition, some people with a autonomic nervous system are sensitive to caffeine. After the initial stimulation phase, the body may experience a compensatory reaction that causes blood vessels to dilate or heart rate to change, causing feelings of fatigue and dizziness. People who have low blood pressure, lack of sleep, skip meals or are stressed for a long time are also more likely to experience this condition.
Experts recommend that if people often feel dizzy after drinking coffee, they should monitor their blood pressure, limit drinking on an empty stomach and ensure enough water during the day. If symptoms recur many times or are accompanied by fainting, prolonged palpitations, they need to see a doctor to determine the cause instead of thinking that it is just a common effect of coffee.
Although most studies show that coffee tends to temporarily increase blood pressure, the body's reaction to caffeine is very different. Therefore, listening to signals from the body and using coffee in a reasonable amount is still necessary to protect cardiovascular health.
