Hyperthermia or heat stroke is a severe condition that occurs from extreme exposure to the sun. It results into dehydration first and then the person is not able to sweat fast to dissipate the heat. It can lead to headache, nausea and vomiting, dizziness, red, hot, and dry skin, muscle weakness or cramps and rapid heartbeat.
it makes sense because they are prescribed by a doctor, and you should trust your doctor, but they need to realize that any drugs are dangerous because of overdoses and using them when you dont need to.
