Getting rid of a headache –
Place your hands under ice-cold running water for a few minutes. Honestly try to keep them there as long as possible. Then as soon as you can’t take it anymore rub your hands with a dry towel until you feel a burning sensation.
This is what is referred to as cold therapy. Stress from fluctuations in temperature increases blood circulation. Thus, if you have problems with your heart and blood vessels, you’d better skip this method.
