Hypothermia occurs when the body gets cold and loses heat faster than the body can make it.
A rectal temperature is considered the most accurate body temperature. A normal rectal body temperature ranges from 97.5°F (36.4°C) to 99.6°F (37.6°C), and for most people it is 98.6°F (37°C). For information on how to take an accurate temperature, see the topic Body Temperature.
Because dizziness can involve so many parts of the body -- the ears, brain, or heart, to name a few -- your doctor will probably take a careful history of your symptoms, do a brief exam, and make a proper referral to a specialist if necessary.
Make sure you describe the sensation you feel thoroughly, since dizziness can be many things to many people.
Sometimes a normal, healthy adult has a low body temperature, such as 96°F (36°C). If the person with the low body temperature is not ill, does not have any other problems, and is not an infant or an older adult, then evaluation usually is not needed.
What can cause hypothermia?
Hypothermia can occur when you are exposed to cold air, water, wind, or rain.
Your body temperature can drop to a low level at temperatures of 50°F (10°C) or higher in wet and windy weather, or if you are in 60°F (16°C) to 70°F (21°C) water. If you have mild hypothermia, home treatment may be enough to bring your body temperature back up to normal.
Shivering, which may stop if body temperature drops below 90°F (32°C).
What can happen from hypothermia?
Hypothermia is an emergency condition and can quickly lead to unconsciousness and death if heat loss continues. It is very important to know the symptoms of hypothermia and get treatment quickly. Often a hiker or skier's body temperature will drop really low before others notice that something is wrong. If someone begins to shiver violently, stumble, or can't respond to questions, it may be hypothermia and you need to warm him or her quickly.
