Why are summer people easily irritable?

First, the hot weather in summer will make the heart beat faster. Under normal circumstances, the heartbeat of a healthy person is about 75 times per minute. If you are in a high temperature environment, your heart will accelerate, even exceeding 100 beats per minute. This huge burden can be compensated by a healthy heart in a short time, while an unhealthy heart is difficult to cope with and may lead to heart failure.

Second, high temperature will make the body sweat a lot. People sweat a lot in high temperature environment, which will cause "electrolyte disorder", thus causing drastic changes in the intensity and speed of heartbeat. In addition, autonomic nervous disorder may cause the heart to run out of control like a runaway horse.

Third, the weather is sultry, patients are prone to impatience, and autonomic nerve disorders can easily lead to arrhythmia.

Fourth, the summer weather is hot and dry, and the days are long and the nights are short, which greatly reduces the quality of sleep. Patients with cardiovascular and cerebrovascular diseases who lack rest are prone to get sick.
