Gyms, especially newly-built gyms, often have building pollution, such as radioactive radon and ammonia pollution, as well as formaldehyde and benzene pollution caused by decoration and indoor furniture. These pollutions will bring hidden dangers to the health of fitness people.
People who go to the gym to exercise will also cause air pollution, mainly including the following:
(1) carbon dioxide pollution
Studies have proved that the amount of carbon dioxide produced by breathing changes with the change of human activity, and the amount of carbon dioxide produced during strenuous exercise is about ten times that at rest. Especially in the gym, people are crowded, and breathing carbon dioxide can easily cause nausea, headache and other discomfort.
(2) Inhalable particulate pollution caused by exercise
In the process of sports, there will inevitably be some dust in the venue, as well as dust on clothes, shoes and socks. These particles can be inhaled into the human respiratory system and even into the lungs. They may not only become carriers of microorganisms, but also contain toxic substances or other pathogenic and carcinogenic substances.
(3) Odors and microorganisms discharged from the body surface
The malodorous substances in indoor air mainly include ammonia, methyl mercaptan, hydrogen sulfide, acetaldehyde and styrene. At the same time, bacteria, viruses and particulate matter in the air also exist together and change with the amount of dust in the air. Especially in public places where people are concentrated, there are many microorganisms and suspended particles in the air, which are more likely to cause harm to human body.
Noise pollution is also a kind of pollution that needs attention. When doing exercise, loud password sound and powerful 1234 are the signs of the gym, but if the sound is too loud, it will become a kind of noise pollution. Noise will accelerate myocardial aging and increase the incidence of myocardial infarction. People who are exposed to noise for a long time will also increase the secretion of adrenal glands in the body, resulting in a series of uncomfortable symptoms such as vasoconstriction, elevated blood pressure, increased heart rate, headache, forgetfulness, decreased attention and weakened digestive ability.
In order to prevent indoor environmental pollution in gymnasiums from harming human health, experts remind everyone to pay attention to the following aspects:
1 Choose a gym with excellent equipment and pay attention to eliminating and reducing indoor environmental pollution.
Pay attention to ventilation during exercise to minimize the harm of dirty air to the body.
Try to avoid going to the newly-built gym to exercise and prevent the pollution of formaldehyde, benzene, carbon dioxide and other substances.
