Many people suffer from various respiratory diseases due to their immune system dropping at the change of seasons due to the wide daily temperature difference between day and night and dry weather. When temperature changes are large, the human body has difficulty maintaining an appropriate body temperature, causing fatigue and reduced immunity. As the body transitions from the hot summer to the chilly fall, the body that cannot adapt to the temperature change suffers from not only respiratory diseases but also various types of allergic rhinitis, dermatitis, and cardiovascular diseases. What diseases should I watch out for during the change of seasons and how can I boost my immunity?
Low immunity, beware of viral diseases

Colds and flu are the most common diseases during the change of seasons, and when infected with a cold virus, symptoms such as fever, headache, and muscle pain appear. Most cases heal naturally within 1 to 2 weeks, but if symptoms are severe or persist for a long time, it is recommended to visit the hospital.
In particular, it is best to prepare in advance for the influenza virus that causes the flu by getting vaccinated. Viruses or bacteria may take advantage of weakened immunity to cause inflammation. Representative examples include bronchitis, pneumonia, tonsillitis, and rhinitis. When you get bronchitis, symptoms mainly include runny nose, cough, and phlegm. Unlike colds, bronchitis symptoms often last for a long time. If a high fever persists for several days and difficulty breathing occurs, pneumonia may be suspected.
Housewife Yang (44) was recently admitted to the hospital with a high fever. He said, “The cold symptoms continued, so I bought cold medicine at the pharmacy and took it, but it didn’t get better.” He added, “Suddenly, my fever rose to nearly 39 degrees and I got chills, so I rushed to the hospital.” He said, “The doctor said I had symptoms of pneumonia and told me to be hospitalized right away, so I was hospitalized for three days.” He added, “During the change of seasons, my immune system weakens and I’m prone to catching the flu, so I have to be really careful.”
Children are vulnerable to allergic rhinitis and atopy… Prevention by maintaining appropriate humidity
Children are especially susceptible to allergic rhinitis because their immunity is weaker than that of adults. Allergic rhinitis in children is prone to recurrence once symptoms appear, and often becomes chronic if not managed well. During seasonal changes, allergens such as pollen and mold increase, which can worsen symptoms of rhinitis or atopic dermatitis.
Maintaining appropriate humidity indoors using a humidifier helps prevent rhinitis. You should clean your home frequently and wash bedding in hot water to prevent dust and mites.
Housewife Kang (34) had her 100-day-old child hospitalized last month. He said, “They usually say that 100-day-old children don’t get sick because their immunity is high, but I heard that my child had a bad cough and had to go to the hospital and be hospitalized.” He added, “I think it was because I turned the air conditioner on and off frequently because it was so hot in the summer.” He said.
He added, “The doctor said that the child seemed to have rhinitis and that we should pay attention to our diet and home environment from now on.”
It is necessary to maintain body temperature by eating warm food.
Food is important when your immunity is low like this. Eating cold food consumes more energy than necessary to digest it, which reduces the energy that should be used for immune cells, which has a negative effect on immunity. The intestine is the body’s largest immune organ, where approximately 70% of the body’s immune cells are concentrated. Eating warm food to aid digestion and maintain body temperature plays a big role in improving immune function.
According to the results of an overseas study, drinking 500 ml of water before a meal increases metabolism by 30%, and increasing the temperature of the water from 22ºC to 37ºC increases metabolism by 40%. Drinking warm water can also help boost immunity. Research has shown that when body temperature drops by 1 degree, immunity weakens by 30%. In the end, if you frequently drink warm water during the change of seasons, your body temperature will rise and your immunity will also increase.
Mr. Lim, 70 years old, said, “I maintain my health by drinking warm water and tea frequently. I am happy because I have no pain and when I get a health checkup, I am happy because my body is healthy for my age.”
Making exercise a part of your daily routine and getting enough sleep can boost your immunity.

The organ that generates the most heat in our body is muscle, and muscles strengthened through exercise increase body temperature and help blood circulation, thereby improving immunity. Fall is a great season to exercise outdoors and feel the cool breeze. If you try to improve your cardiopulmonary and muscle strength through various physical activities such as taking a walk in the sun, stretching, or walking barefoot, you will be able to achieve not only health but also weight loss effects.
At this time, be careful not to injure your knee joints through excessive exercise. When the temperature difference between day and night is more than 10 degrees, it causes muscles and ligaments to contract, increasing the risk of physical injury. In particular, many people suffer from knee arthritis due to a rapid increase in activity as the weather warms up. Additionally, it is important to get enough sleep. Sleep is an important time to filter out waste accumulated from daytime activities and optimize and strengthen the body’s homeostasis.
If you lack sleep, the number and function of cells responsible for immune function decrease, making you more susceptible to diseases such as colds. Therefore, adults should sleep an average of 7 to 8 hours to ensure a smooth immune response. [시사캐스트]
