Not sure whether to use ice or heat on an injury? This infographic should help. π₯π₯΅π₯Άπ§
The basic rules are if you have an acute injury that is swollen use ice for the first 48 hours, any chronic injury or muscle strain this is not swollen will benefit more from heat treatment. Ice reduces blood flow, heat increases it.
If you suffer a sudden sprain or strain, applying cold can reduce swelling by slowing cell activity, constricting blood vessels, and blocking the release of chemicals known as histamines. The application of cold can also decrease pain by numbing the area.
In most cases heat is the best choice as bringing more blood flow to an area of muscle strain, tendon injury or arthritis will help dilate blood vessels, remove toxins and bring in more oxygen and nutrients to help the tissue repair itself.
The most important point is to always have a barrier between the heat/cold source and your skin to prevent burns.
Hope that helps! π€
