Hello, I can understand your concern for sudden occurrence of rashes all over the body. Rashes are quite common condition caused by bursting of allergy producing cells known as \"mast cells\" due to certain aggravating factors present in the environment. As the chemical inside them is released it produces a rash which you have mentioned. There can be multiple factors producing this condition which are included in day to day life and sometimes it is really difficult to find one exact cause. In your case you are correlating it with exercises, hot climate, spicy food. So it is better to stay away from the offending factors. The long term effective treatment for this is by oral anti histamine like loratadine under medical advice. It is one of the Chat Doctor.  Do not scratch or rub the skin as it can lead to further aggravation. Take care.
