What is hypothermia and hyperthermia

In hyperthermia, the set point remains unchanged while in fever it changes. Dry, warm skin, nausea, vomiting, headache, and excessive sweating are symptoms of hyperthermia. Common causes of hyperthermia are heat stroke , drugs and protective equipment.

Heat stroke occurs because body mechanisms of heat loss are overwhelmed by metabolic heat generation and high environmental temperature. Many antipsychotics , selective serotonin reuptake inhibitors, monoamine oxidase inhibitors, tricyclic antidepressants, amphetamines, cocaine, halothane, succinyl choline, and anticholinergic drugs can cause hyperthermia.

If they do, then hyperthermia can be excluded. Low cost measures like light dressing, wet clothing, keeping wet with sweat, fans, air conditioning are very effective in preventing hyperthermia. The underlying cause for hyperthermia should be removed. Drug induced hyperthermia indicates the need for immediate cessation of the offending drug.

Studies have shown that fever reducing drugs have a role in treating hyperthermia. Hypothermia may occur if you are exposed to cold temperatures or a cold, wet, windy environment for a long amount of time.

Getting drenched in the rain on a cold, windy day, and not drying off, for example, may lead to hypothermia. The following symptoms of hypothermia include:. List adapted from Hypothermia from the Mayo Clinic. Complications of hypothermia may include getting frostbite and subsequent loss of limbs or coma. If you or someone you know may be suffering from hypothermia, immediately contact a health care provider or call Keep the affected person warm, dry, and indoors while waiting for medical help.

To prevent hypothermia, it is helpful to stay warm and dry in cold weather and avoid excessive alcohol consumption. In addition:. Now, hyperthermia, on the other hand, typically occurs on humid, hot days temperature higher than Neice vs. Buisness vs. Beeing vs. Amature vs. Lieing vs.
