Question and Answer
Many people start their day with a cup of coffee, even though it may cause hand tremors, a rapid heartbeat, and a slight sense of anxiety. Why do these bodily changes occur? Caffeine reaches its peak concentration in the blood 30 to 60 minutes after consumption, temporarily raising heart rate and blood pressure. When coffee is consumed on an empty stomach, caffeine is absorbed more quickly, making its effects more pronounced. Many people believe that a rapid heartbeat, internal trembling, and mild anxiety are symptoms of anxiety disorders, but they are actually due to caffeine’s effect of increasing heart rate. Doctors explain that cortisol levels, the hormone responsible for promoting alertness and preparing the body for daily activity, rise immediately after waking up. During the first 30 to 45 minutes after waking, the body is already in a state of natural arousal; therefore, drinking coffee during this period does not add significant energy, as the effects of caffeine coincide with the peak of cortisol activity.
There are no strict rules or an ideal time for drinking coffee, but individuals who are more sensitive to caffeine may benefit from waiting some time after waking before consuming it, which can help avoid hand tremors and a rapid heartbeat. Coffee itself does not harm the heart in healthy individuals. Consuming up to 400 milligrams of caffeine daily—equivalent to three to four cups of coffee—is considered safe for healthy adults. A single dose of up to 200 milligrams, roughly equivalent to two cups, typically does not cause a noticeable increase in blood pressure. Pregnant women are advised not to exceed 200 milligrams of caffeine per day. Moderate caffeine consumption helps activate the body and improve concentration.
Coffee is a natural part of daily routines, but it is best consumed in moderation, avoided on an empty stomach, and preferably taken without sugar. If a single cup of coffee repeatedly causes heart palpitations or hand tremors, it is essential to consult a specialist and undergo appropriate medical tests. Source: Novosti
