Air-conditioning sickness is a general term for the various physical symptoms that appear when air conditioners or other cooling devices are overused and the temperature difference between indoors and outdoors becomes large. It is not an officially defined medical diagnosis, but headache, fatigue, and digestive problems may occur. In most cases, symptoms may improve within a few days if use of cooling devices is reduced. If symptoms are severe or accompanied by a high fever, please consult a medical specialist.

Angina (Angina Pectoris)

#angina, #chest pain, #myocardial infarction, #coronary artery, #atherosclerosis, #stent, #sudden death

Angina is a cardiovascular condition in which the coronary arteries — the blood vessels that supply oxygen and nutrients to the heart — become narrowed, causing a dull chest pain. Because heart disease can be a major cause of sudden death, if you feel chest discomfort that is different from what you normally experience, please do not delay in consulting a medical specialist.

Asthma is a chronic respiratory condition in which the airways (the passages through which air moves in and out of the lungs) become hypersensitive, often due to allergic reactions, and narrow, causing recurring coughing, wheezing, and shortness of breath. It is sometimes mistaken for a severe cough or cold, which can delay proper treatment. Symptoms can worsen with exposure to yellow dust, fine particulate matter, or pollen. If you have recurring coughing or shortness of breath, please consult a pulmonologist or allergist.

If you develop hives or shortness of breath after eating a certain food, it may be a food allergy, which can be life-threatening. Please do not take it lightly; be sure to see an allergist or pulmonologist for accurate testing. If you have difficulty breathing, throat tightness, or feel faint after eating, call 119 (Korea's emergency number) immediately, and use your epinephrine auto-injector if one has been prescribed.

Heat Waves and Heart Health

#heat wave, #sudden cardiac death, #heat stroke, #heat-related illness, #heart attack, #angina, #cardiac arrest, #arrhythmia, #hydration, #summer health, #dizziness, #feeling faint, #unsteadiness, #vision going dark, #fainting, #loss of consciousness, #syncope, #breath holding, #difficulty breathing, #shortness of breath, #choking sensation

Extreme heat raises the risk of angina, heart attack, and cardiac arrest by increasing heart rate, promoting blood clotting, and placing added strain on the heart. Older adults age 65 and older, people with cardiovascular disease, and those with chronic conditions such as high blood pressure or diabetes need to be especially careful. On days when a heat wave warning is issued, please stay active indoors for safety.

If symptoms appear, move to a cool place immediately, and if heat stroke is suspected, call 119 (Korea's emergency number) right away. Please consult a medical specialist.

Kidney Cancer

Kidney cancer is a malignant tumor that develops in the kidney. There are almost no symptoms in the early stages, so it is difficult to notice on your own, and in most cases it is found incidentally during a health checkup. Even without symptoms, it is important to detect it early through regular health checkups. If an abnormal finding is detected or you have any concerns, please be sure to consult a medical specialist.

Lung cancer is a malignant tumor that develops in the bronchi or lungs and is the leading cause of cancer death in Korea. It often causes no symptoms in its early stages, so regular screening is important for high-risk groups. Smoking is the leading cause, and quitting smoking is the most effective way to help prevent it.
