Bear in mind if you are taking rectal temperatures that this may read slightly higher and therefore you will need to adjust the reading slightly for any temperature reading.
The Swiss Mountain medicine field guide is likely the best review of hypothermia available. They define hypothermia into four categories. People in this temperature range often find themselves shivering, which is the best way to increase body temperature. If they are showing signs of hunger or dehydration then eating and drinking, along with limited exercise may be of benefit. Because active shivering has stopped people suffering from moderate hypothermia must be actively warmed as they are unable to warm themselves.
While there may be many stages of hypothermia, the main intervention required is, of course, heating up the affected person. If you find someone shivering, this is a good sign, as it implies that they are still in the initial stages of hypothermia.
Shivering is a mechanism used by the body to raise the peripheral or external temperature of the skin. As the skin cools the body redirects central blood flow to the surface. Stage II hypothermia and onwards is caused by the continuous return of this cold blood from the skin, which in turn drops the core body temperature.
Due to the metabolic changes hypothermia induces at the cell level, CPR is actually not recommended for moderate stages of hypothermia and above. This is due to the irritability of the heart, and unless professional care is more than three hours away nothing more than respiratory support and evacuation should be provided. Keep in mind that evacuation is recommended for all people who are suffering from moderate hypothermia and worse. The main goal of hypothermia treatment in the wild, that is hypothermia first aid , is to prevent further heat loss of the victim whilst rewarming them as much as possible.
If the victim has fallen into a body of water, the obvious first step is to remove him or her from it. It is important to be gentle with hypothermia victims, and to limit moving them only as necessary. Do not try to massage or rub heat back into them. Sudden, jarring movements may in fact trigger a heart attack.
Overnight temperatures in the area were near the freezing point, and though a cause of death has yet to be confirmed, investigators have not ruled out paradoxical undressing and hypothermia, according to the Cliffview Pilot.
Hypothermia occurs most often among people who abuse drugs or alcohol, the chronically ill, very old or very young people, and those who are malnourished, according to the National Institutes of Health.
The best ways to avoid hypothermia are to wear proper clothing, such as mittens not gloves , hats, scarves, and dry, windproof layers of clothes. Drinking alcohol can actually help bring on hypothermia, since alcohol — in addition to encouraging risky and irrational behavior — can also induce vasodilation, the opening up of blood vessels that results in bodily cooling. Hypothermia is a serious condition and should be treated by a medical professional as soon as possible.
First-aid treatments include warming the person with dry, warm blankets; person-to-person warming; applying warm compresses; and — if the victim is alert enough to swallow — administering warm, sweetened nonalcoholic fluids. It is also important to educate the community members to be aware of bad weather, prepare for emergencies and responding appropriately for them.

They are also unable to touch their thumb with their little finger, because their hand muscles don't work well. Mild hypothermia is sometimes used on purpose by doctors for treating some medical problems. It takes blood away from the skin, hands and feet, and puts it to the brain and important internal organs. This helps when the person is bleeding from cuts or other wounds, and also helps when the patient goes into cardiac arrest. The person begins shivering very strongly.
Brian Salazar-Prince. To prevent hypothermia, you should wear clothing which serves as a good insulator. Use clothes that have a lot of padding and dress in layers. The more you're wearing, the better.

Chemical heat packets, strategically placed, can help increase body temperature.
Producing heat takes energy! Bring an adequate supply of food to fuel your body's internal engine. Hypothermia is a serious condition. If you or someone with you is experiencing serious symptoms, seek medical help.
