Symptoms Caused by Heat & Cold Conditions

The human body can adapt to a wide range of environments. However, there are situations when extreme heat or cold can begin to adversely affect a person's body and mind. When your body temperature gets too high, this is referred to as heat stroke. Heat stroke is often accompanied by dehydration, which is a lack of water content in the body. When your body temperature gets dangerously low, this is referred to as hypothermia. Mild hypothermia is similar but more difficult to detect.

  1. Heat Stroke

    • Heat stroke is caused by extended exposure to heat, humidity or over-exertion. These situations can cause your body temperature to rise to extreme levels. Heat stroke symptoms can start with simply a headache and dizziness. An outside observer may notice red, dry skin and signs of agitation and confusion. Heat stroke can eventually lead to seizures, hallucinations and a loss of consciousness. If you observe any of these symptoms in yourself or someone else, you should immediately get the person indoors and apply ice or cold water to his skin.

    Dehydration

    • Many heat stroke victims also suffer from dehydration. Dehydration is caused by an inability of the body to retain or replenish fluids. This can happen through excessive sweating in an over-heated or humid environment. The most mild symptom is thirst. If left untreated, you will begin to experience dry-mouth, an increased heart-rate and trouble breathing. For sufferers of mild dehydration, simply rehydrate with water or a sports drink. If symptoms appear serious, you should immediately call an ambulance.

    Hypothermia

    • Be aware of hypothermia symptoms when spending time outdoors in a cold environment

      Hypothermia is caused by over-exposure to extremely cold water or air for an extended period of time. The most obvious sign of hypothermia is shivering. Many symptoms beyond shivering are less obvious, such as confusion, apathy and lack of coordination. If you know someone has been outside in cold weather and is exhibiting these signs, you should immediately call 9-1-1.

    Mild Hypothermia

    • Mild hypothermia, unlike hypothermia, can be caused by a poorly-heated room or house. It is often more difficult to ascertain if you are suffering from mild hypothermia than hypothermia because it is not related to outdoor exposure or shivering. It is most commonly diagnosed in infants or the elderly. Symptoms can include dizziness, vomiting and a lack of coordination. If you believe someone is suffering from mild hypothermia, cover him with blankets and call 9-1-1.
