Heat stroke can cause headache. After heat stroke, the central nervous system is the first to be affected, usually manifesting as headache, dizziness, uncoordinated arms and legs, lack of mental concentration, and sometimes nausea and vomiting. If the central thermoregulatory system is affected, it will lead to a weakening of the heat dissipation function in the body, resulting in fever, which will also lead to the onset of headache when the fever reaches a certain level. To treat headache, first of all, after heatstroke must be more hydration, if possible, you can use oral rehydration salts to drink water, but also be able to replenish the lost electrolytes. In addition, if the headache is mild, you can take traditional Chinese medicine, such as ten drops of water and patchouli water. If the headache induces fever and severe headache, you can also take antipyretic and analgesic drugs, such as ibuprofen and acetaminophen, which can solve the problem.
