Panic after drinking Iced Americano is likely to be caused by the high concentration of caffeine in Iced Americano, or by caffeine’s excitation of the sympathetic nerves aggravating the symptoms of coronary heart disease, arrhythmia and other diseases.
Panic, also known as palpitations, is often a feeling of heart discomfort that occurs when the number and rhythm of the heart beats change significantly.
Iced Americano is a drink often consumed by many people, but because Americano is extracted for a relatively long time, it releases more caffeine, resulting in a high concentration of caffeine in Americano. And caffeine is a plant alkaloid that has the effect of stimulating the sympathetic nerves.
After drinking a cup of iced Americano, because of the sympathetic nerve stimulation effect of caffeine, the heartbeat is accelerated, resulting in palpitations. If you suffer from coronary heart disease, arrhythmia and other diseases, because the caffeine has the effect of accelerating the heart rate, so it will shorten the diastolic period of the heart, the blood supply to the heart muscle cells will be further reduced, resulting in the feeling of palpitations.
If the symptoms of panic after drinking ice Americano, you can drink more water to increase the excretion of caffeine in the urine, in order to reduce the palpitations; if the palpitations for a long time and have a tendency to gradually aggravate, it is recommended to go to the hospital in a timely manner, to clarify the cause of the disease, under the guidance of the doctor’s treatment, to avoid delays in the condition.
