Do you start your day with a cup of coffee? A cardiologist says your morning routine may be doing more than just waking you up and offers practical advice on how to avoid unwanted side effects.

Dr. Natalia Vasyukova, a cardiologist, explains that many people begin their day with coffee, even though it can sometimes cause hand tremors, a faster heartbeat, and mild feelings of nervousness.
"Caffeine reaches its peak concentration in the bloodstream about 30 to 60 minutes after consumption," she said. "It temporarily increases heart rate and blood pressure. When coffee is consumed on an empty stomach, caffeine is absorbed more quickly, making its effects more noticeable."
She added that many people mistake symptoms such as a racing heartbeat, internal shakiness, and mild anxiety for stress or panic, when they are often simply the result of caffeine stimulating the cardiovascular system.
According to Dr. Vasyukova, cortisol the body's natural hormone responsible for alertness and preparing the body for daily activity rises immediately after waking up.
During the first 30 to 45 minutes after getting out of bed, the body is already naturally alert, meaning that drinking coffee during this period may not provide much additional energy because caffeine's effects overlap with cortisol's natural peak.
She noted that there is no strict rule or universally ideal time to drink coffee. However, people who are particularly sensitive to caffeine may benefit from waiting a while after waking before having their first cup, which could help reduce symptoms such as hand tremors and rapid heartbeat.
The cardiologist also emphasized that coffee itself does not harm the heart in healthy individuals. Up to 400 milligrams of caffeine per day roughly the equivalent of three to four cups of coffee is considered safe for healthy adults.
A single intake of up to 200 milligrams, or about two cups of coffee, generally does not cause a significant increase in blood pressure.
For pregnant women, she recommended limiting caffeine intake to 200 milligrams per day.
She also noted that moderate caffeine consumption can help improve alertness and concentration.
Dr. Vasyukova concluded by saying, "Coffee is a normal part of many people's daily routine, but it's best enjoyed in moderation.
Avoid drinking it on an empty stomach, and whenever possible, drink it without sugar.
If even one cup of coffee consistently causes heart palpitations or hand tremors, you should consult a healthcare professional and undergo the appropriate medical evaluation."
