The headache and nausea caused by heat stroke should be treated in a causal way, that is, treating heat stroke in order to relieve the headache and nausea. Usually, the treatment of heat stroke is as follows: 1. Patients must be removed from the environment of heat stroke as soon as possible, such as away from the high temperature and direct sunlight, to a cool, dry and ventilated environment for symptomatic treatment. 2. Patients should be quickly relieved of damp and tight clothing, and their bodies should be physically cooled by applying ice water to the head, neck, trunk, armpits, and groin. 3. The patient should be given chilled glucose water and saline, mung bean water, iced sugar water, or some patchouli water to relieve the headache and nausea.
