I wasn’t bitten by an insect, but my body is itchy. When the temperature drops below freezing, it seems to be toxic. When I scratch it with my hand, my skin spreads.

Why is the whole body so itchy? In particular, there are many cases where the elderly suffer from itching. “(Itching) is the most common skin disease in people over the age of 65,” said Dr. Kenneth Arnd, a dermatologist and former editor of the Harvard Special Report on Skin Care. The skin barrier does not work as well as before, and it can cause a sensitive reaction to even minor stimuli. “Also, the skin’s immune response decreases, fat and blood flow decreases, and sensory perception also changes, leading to severe itching.”

In winter, more people suffer from itching. US’Harvard Health Publishing’ introduced the causes and treatments of common itching.

What causes itching?

There are various causes of itching, such as environmental lifestyle, drug allergy, etc. First, living in an excessively dry environment or frequent showering in hot water can dry your skin and cause itchiness. Unhealthy diets such as lack of sleep, smoking, and instant food can also cause itching. Anything that comes into contact with the skin, such as detergents, cosmetics, and pollen, can cause itching due to an allergic reaction.

Diseases or drugs can also be the cause. For example, people with diabetes develop neuralgia and itchiness. Nerve damage that causes tingling and pain can show the same symptoms. Itching can also be a symptom of liver, kidney, or thyroid disease. Some drugs to treat high blood pressure are also of doubt. According to Dr. Arndt, even with the same drugs as before, pharmaceutical companies can change the ingredients that color the tablets, which can cause itching.

Psychological factors such as stress, anxiety, and obsessive-compulsive disorder can also cause itching. They can amplify all kinds of symptoms, including itchiness. If, for any reason, your daily rhythm often breaks due to itching, it is a good idea to see a doctor.

How to relieve itching?

Resolving itching begins with changing your lifestyle. Do not bathe or shower frequently with excessively hot water. While reducing the number of times, lower the temperature of the water and use a non-irritating soap. And, to keep your skin moisturized, apply a cream right after you shower or wash your hands. It’s not good that the house is hot and dry. Lower the indoor temperature and maintain 40% humidity.

If you want to know if a drug or supplement is the cause, try replacing the drug with another type and stopping the supplement for a few weeks. If aging was simply the cause, Dr. Arnd recommended a local anesthetic patch or cream containing gabapentin, lidocaine, or an antidepressant, or phototherapy using ultraviolet rays.

Above all, the easiest remedy for itching is to moisturize the body from time to time and keep the environment dry.
