The heart works tirelessly every minute and every second, and the normal heart rate is 60 ~ 100 times per minute; If more than 100 times, it is called tachycardia. However, a fast heartbeat is not all a sign of heart disease. Here are seven reasons why my heart beats too fast. Let's have a look.
Stress and anxiety
These mental factors cause the release of adrenaline and cortisol hormones, raising heart rate and blood pressure. If you can relieve your mood, the phenomenon of tachycardia will disappear by itself. Try to relax and practice deep breathing, yoga and Tai Chi.
Irritant beverage
Excitatory substances such as caffeine, alcohol and nicotine can raise blood pressure and accelerate the heartbeat. Adults should not consume more than 400 milligrams of caffeine a day, roughly equivalent to four cups of coffee.
Lack of sleep
Lack of sleep can also increase the secretion of cortisol hormone, resulting in increased heart rate and blood pressure. The National Sleep Foundation recommends that adults get seven to nine hours of quality sleep a night.
Pain
The stress reaction caused by acute pain will cause the increase of blood pressure, heart rate, pupil dilation and the increase of cortisol content in the blood, and the heartbeat will return to normal after treatment.
Pregnant
The pregnant woman's heart is under more pressure. By the end of pregnancy, the uterus receives 1 / 5 of the mother's blood supply, increasing the amount of blood pumped by the heart by 30% ~ 50%, resulting in a faster heartbeat.
Thyroid problems
A variety of hormones secreted by the thyroid gland regulate the function of the main organs of the human body. When the thyroid hormone is insufficient (hypothyroidism), the heart rate will decrease, while excessive thyroid hormone (hyperthyroidism) will increase the heart rate. If it is suspected that the heart rate is accelerated due to thyroid problems, five tests of thyroid function should be carried out.
Dehydration
When dehydrated, the effective blood volume will be reduced, resulting in lower blood pressure, which forces the heart to work harder and accelerate beating. After sweating a lot, drink water or drinks containing electrolytes in time to supplement the lost body fluids and minerals.
