Please look at the quality of air before the exercise
Haze and haze can easily lead to decreased respiratory defenses and lung function. People who regularly participate in long-distance running and basketball activities must first understand the air PM index of the day before going out. Such haze weather and other strenuous exercise such as long-distance running will not only fail to achieve good exercise results, but also endanger their own physical health.
What are the hazards of running in haze?
Injured lungs
The most damaging haze is the respiratory system. Once the sulfur dioxide and ammonia oxide in the haze have been inhaled into the body, it will enter the alveoli along with the airway, damage the lungs, and hinder the normal gas exchange between the lungs, causing the body to appear Asthma, lung cancer, etc.
Induced rhinitis
When running in hazy weather, the nasal cavity will inhale large amounts of dust, particles, and pollutants. Once inhaled into the nasal cavity, it will stimulate and destroy the nasal mucosa, make the nasal cavity become dry, reduce the defensive ability of the nasal mucosa, induce rhinitis, sinusitis, and nasal mucosa. Inflammation and other nasal diseases.
Accelerating arterial stiffness
The inhalation of pollutants from running in smog days will greatly increase the damage to the vascular endothelium. Mist contains a lot of dust, pathogenic microorganisms, etc., when these sources of pollution with the human body's respiratory system into the blood, causing damage to the vascular endothelial cells, accelerate the formation of vascular atherosclerosis.
Induced vasospasm
When running in cold, humid fog and air, cold air is inhaled into the body. The blood vessels in the human body cannot adapt to sudden cold stimulation, narrow the blood vessels, and induce vascular spasm.
Induced high blood pressure
Running on a hazy day, in addition to causing cardiovascular and cerebrovascular diseases when the air temperature is low, it can also cause depression and irritability due to low air pressure and drowsy air, which induces high blood pressure in middle-aged people.
