2. I am afraid of fatigue. Sudden death of young and middle-aged people is frequently seen in the media, and overwork is the number one natural enemy of the heart. Sudden cardiac death is not caused at one time. Long-term irregular work and rest, excessive stress, depression or mood swings, obesity, heavy smoking and drinking may all lead to the rupture of coronary atherosclerotic plaques, leading to acute lesions such as thrombosis, and also lead to coronary artery spasm or severe coronary artery stenosis. The patient's myocardial oxygen consumption increased significantly, leading to acute myocardial ischemia and sudden death.
3. The stomach is afraid of cold. For stomach, "cold" is the most unacceptable. Once the stomach is stimulated by cold air or cold food, it is easy to contract spasm, leading to discomfort such as stomach spasm and diarrhea. In summer, many people like to eat ice cream and drink iced drinks to relieve the heat. Although I felt cold at that time, my stomach was very uncomfortable. After a large number of cold drinks enter the gastrointestinal tract, not only will the blood vessels of the gastrointestinal tract contract suddenly, but the blood flow will decrease, causing spasmodic contraction of the gastrointestinal tract, and it will also interfere with the normal peristalsis of the gastrointestinal tract, leading to digestive dysfunction and affecting the secretion of digestive juice. If you eat some indigestible food or unclean roadside stalls at this time, it will double the stimulation of the gastrointestinal tract.
4. The lungs are afraid of poor environment. The lung has high requirements on the environment, and fresh air is its favorite. If you stay in an environment with dense exhaust gas and smoke for too long, your lungs will protest. The lung itself has a perfect self-purification system, even particles smaller than 2 microns in diameter will be inhaled, swallowed by alveolar macrophages, and finally excreted with sputum through the respiratory tract. However, if you continue to inhale a lot of particulate matter, the defense barrier of the lungs will gradually become fragile. Excessive precipitation of inhalable particles will reduce the ability of lung to inhale oxygen, reduce the phagocytic function and viability of macrophages in alveoli, and lead to the decline of lung's ability to eliminate pollutants.
5. Kidney is afraid of staying up late to pee. Staying up late can damage the kidneys, so some people who stay up late for a long time, have high work pressure and like to drink strong tea and coffee are prone to kidney problems. When work and study are busy, many people have experienced the situation of holding their urine, which is actually very harmful to their health. If urine stays in the bladder for too long, it will breed bacteria, which will retrograde to the kidney through the ureter, leading to urinary tract infection and pyelonephritis. Once this kind of infection occurs repeatedly, it will cause chronic infection and is not easy to cure.
