During the hot summer, cool indoor spaces are welcome, but staying for a long time in a place where the air conditioner is constantly running can sometimes make you feel uncomfortable instead. If you feel chilly, tired, or develop a headache without any particular reason, it may be worth considering the possibility of air-conditioning sickness rather than simple fatigue. 😊
These changes can occur more easily in environments with a large temperature difference between indoors and outdoors, such as offices and large shopping malls. Today, we’ll look at the characteristics of air-conditioning sickness symptoms, how they differ from a cold, their causes, and ways to manage them in everyday life!

🌡️ Air-Conditioning Sickness Symptoms: What Signs May Appear?
Air-conditioning sickness symptoms refer to various discomforts that occur when the body’s temperature-regulation function is temporarily strained by a large temperature difference between indoors and outdoors.
Typical symptoms may include feeling chilly and achy, as if you have the flu, as well as headaches, fatigue, and shoulder stiffness. You may also experience a runny nose or a scratchy throat, and in some cases, indigestion or a cold sensation in the abdomen.
In women, there have also been reports of temporary changes in the menstrual cycle or discomfort in the lower abdomen. The severity of these changes varies from person to person, and they may continue for several days.
Above all, a characteristic of air-conditioning sickness is that it often appears as a decline in overall physical condition rather than as a problem with one specific organ.

🤧 How Can You Tell the Difference Between a Cold and Air-Conditioning Sickness?
Cold symptoms and air-conditioning sickness symptoms can feel similar, so they are often difficult to distinguish.
Because a cold is caused by a viral infection, it may involve a fever, and symptoms such as coughing, phlegm, and a sore throat often gradually worsen over time. In contrast, a decline in condition caused by air conditioning often begins after spending a long time in a cold environment and may improve after getting sufficient rest in a warm place.
Another difference is the surrounding environment. If you feel uncomfortable in an office with strong air-conditioning but your symptoms lessen when you return home, the indoor temperature may be influencing your condition.
However, if a high fever persists or is accompanied by severe coughing or difficulty breathing, do not assume that it is simply air-conditioning sickness; it is advisable to check whether there is another cause.


❄️ Causes of Air-Conditioning Sickness and Prevention in Daily Life
The main cause is a sudden, large difference between indoor and outdoor temperatures. In general, when the difference between the two environments is too great, the autonomic nervous system may be strained while adapting.
To prevent it, it is helpful to avoid setting the indoor temperature too low and to keep it at an appropriate level. 🌿 Adjusting your seating position so that the air conditioner does not blow directly on your body or preparing a lightweight cardigan can also be helpful.
Lightly stretching about once an hour or briefly going outside to move your body may also help with blood circulation. Do not forget to drink enough water to maintain hydration.
Maintaining regular meals and getting enough sleep may have a positive effect on preventing air-conditioning sickness symptoms.

💪 Management Methods and Precautions for a Faster Recovery
If you are already feeling unwell, it is best to first adjust the indoor temperature appropriately and keep your body warm. Drinking lukewarm water or warm tea and getting plenty of rest may help with recovery. ☕
A light walk or stretching can help relax tense muscles, and maintaining a regular daily rhythm is also important.
However, if symptoms persist for a long time, you develop a high fever, or severe coughing and respiratory problems occur together, it may be another condition, so it is advisable to seek appropriate medical care.
In summer, staying cool is important, but maintaining the body’s balance is even more important. Even small changes in daily habits may help reduce air-conditioning sickness symptoms, so try managing both the indoor temperature and your rest periods.
Today, we looked at air-conditioning sickness symptoms, how they differ from a cold, their causes, and prevention methods. To enjoy a healthy summer, it is especially important to practice appropriate air-conditioning use along with a regular lifestyle.
