eli5: what is the difference between putting heat vs cold on muscles?
In: 2
Heat therapy can be a useful tool for relieving muscle stiffness and soreness, especially after exercising or engaging in physical activity. By increasing blood flow to the muscles, heat therapy can improve circulation and help to promote healing.
On the other hand, cold therapy can be helpful in reducing inflammation and swelling, particularly in the early stages of an injury. Cold can numb pain receptors and reduce swelling by constricting blood vessels, which can reduce blood flow to the affected area.
