2. Hyperthermia
Hyperthermia is the exact opposite of hypothermia. As you would expect, it means your body temperature is above the normal range. The most common causes for this is heat stroke. However, the use of certain drugs can cause this symptom too. Since the receptors are not working properly due to serotonin overload the body can fail at thermoregulation. This will cause the patient’s body temperature to drastically increase. This symptom can be dangerous if not taken care of quickly.
Having a raised body temperature for extended periods of time can overheat organs and in particular the brain. This can cause damages to brain cells. Due to the increase in blood pressure from hyperthermia, cardiac output also increases and can cause damage or pose risk to your heart. This is especially so if someone has history of cardiovascular problems.
