Expert recommendations:

Don't drink coffee when you are extremely tired

Does coffee really cause heart palpitations?

Qian Bao reporter interviewed Ding Yahui, deputy chief physician of Cardiology Department of Zhejiang Province People's Hospital, and Chen Shenjie, chief physician of Cardiovascular Medicine Department of Zhejiang Province Hospital of Traditional Chinese Medicine.

Two experts read Cao Ying's micro blog, think Cao Ying's illness is not necessarily caffeine poisoning, but another reason.

Ding Yahui thinks Cao Ying may be overtired, and drink exciting coffee, causing sympathetic over-excitation. " If the sympathetic nervous system is excited for a long time, it will lead to excessive burden on the heart, increase the heart rate, and even produce arrhythmia."

"After the symptoms appeared in her body, considering the high-speed environment Cao Ying was in at that time, she might also be very nervous, and there might be hyperventilation in the middle." Ding Yahui further explained,"That is to say, her breathing frequency has become faster, and the carbon dioxide exhaled from the body has increased." Exhaling too much carbon dioxide will change the pH value of the blood. After the pH value rises, potassium deficiency in the body will also occur. After a potassium deficiency, one's limbs will become weak and weak. In severe cases, one's heart will also experience arrhythmia." Medically, this condition is known as respiratory alkalinosis.

Chen Shenjie also believes that Cao Ying's illness is more like "respiratory alkalis poisoning". This condition is more common in hysterical patients. In this case, rescue is not difficult, breathing slow down, wear a mask, do not need oxygen, reduce carbon dioxide exhalation, can alleviate symptoms. Chen Shenjie said,"Coffee itself does not directly cause palpitations, although it contains caffeine can make people's sympathetic nerves more excited, but for most people, drinking a cup of coffee will not have an accident."

Chen Shenjie believes that Cao Ying's illness after drinking coffee should be only a case, related to her own body. In foreign countries, many cardiologists drink a cup of coffee after surgery.

Ding Yahui pointed out that Cao Ying drank coffee before, there are a few days to stay up late to work, her body should be extremely tired. At this time, choosing to drink strong coffee to refresh is not a wise choice. When the body feels too tired, drinking strong coffee will strengthen the body, and the body will naturally protest.

It seems that instead of discussing whether to drink this coffee with your friends, it is better to care more about your body, don't stay up late to work, and don't put yourself in a state of high tension.
