What is the prognosis (outlook) for people who have a heat illness?

People with heat rash, heat cramps, or heat exhaustion usually recover quickly after treatment. How long it takes a person to recover from heat stroke depends on the person’s age, physical condition, and how quickly he or she receives medical care. A person who has had heat exhaustion or heat stroke may be more sensitive to hot conditions for up to a week after the event. Check with your doctor before returning to work or activities.
