Exercise is beneficial for health, but you need to exercise at the right time and in the right way. Normally, at the time of changing seasons, the weather is cold and the cold air creates a layer of fog, causing fine dust to circulate around the lower floors, causing more harm to health. Fine dust also obstructs traffic and visibility of moving vehicles in the morning.
Therefore, you need to balance your lifestyle and health condition to choose a safe training time frame. If the temperature is high and the air humidity is within a safe level, you can exercise in the morning to increase your body’s resistance. You should eat lightly before exercising and do not exercise too hard.
When humidity is low and temperature drops, you should limit going out early in the morning to avoid pollution and cold. Because, when entering the body, fine dust will penetrate the airways, causing damage to the lining of the trachea and bronchi. They also go deep into the alveoli, the end of the gas exchange organ, causing inflammation and fibrosis of the alveoli, leading to many respiratory diseases. Fine dust that is too small in size penetrates the alveoli and capillaries into the body’s circulation, causing cardiovascular damage, cerebral stroke, and brain damage if exposed for a long time.
People with heart and respiratory problems, pregnant women, children and the elderly are more sensitive to fine dust. Mothers exposed for a long time can experience miscarriage, premature birth, birth defects and death. Exercising early in the morning also increases the risk of stroke, high blood pressure, cardiovascular disease…

In the cold season, you should not go to the gym too early and eat lightly before exercising. Elderly people should practice and exercise gently with exercises such as yoga, relax mentally indoors, in a covered place or, if outdoors, wear a hat, warm coat…
Avoid exercising in places with air pollution, dust, and toxic chemicals. If exercising indoors, make sure the space is well ventilated, open a window or use a fan to create air flow, but avoid cold wind blowing directly on you.
