Whether it is useful to treat winter diseases in summer should be useful, but not all winter diseases are treated in summer. Joint pain or rheumatism caused by a cold in winter will be slightly relieved by sticking plaster or sweating in summer, and it may be less painful in winter through treatment in summer, but it should not be completely cured.
There are still many women who do not pay attention to the diseases of confinement, such as backache and leg pain, which will be slightly relieved in winter and summer. I haven't tried the specific operation, but my family has. When I was young, I wore thin clothes in winter, and then my joints were frostbitten. Every winter he feels uncomfortable, and he doesn't dare to blow the air conditioner in summer. He bought a plaster and stuck it on it in the dog days. I have never heard him say that my joints hurt badly in winter in recent years.
I am not a medical student myself. These are all based on the examples around me. Whether it is suitable for treating winter diseases in summer or not requires detailed consultation with doctors. Personally, I think some diseases are suitable, otherwise, like my family, I can't tell why, but the pain has really stopped in recent years, and some diseases should not be suitable. Sticking dog stickers is useless. Many of them will cause skin allergy and pain, so you should consult a doctor scientifically.
Of course, the most important thing is to protect yourself, such as wearing warm clothes in winter, especially for women. Many girls wear thin clothes to be polite, which will easily freeze their joints. I remember reading a news a few years ago that a girl wore pants that leaked her ankles in winter and finally got sick and went to the hospital. It seems quite serious, so protection is the most important. Of course, if there is a problem, you should seek medical advice reasonably.
