Hypothermia is dangerously low body temperature, below 95 F (35 C).
Alternative NamesLow body temperature; Cold exposure
ConsiderationsPersons most likely to experience hypothermia include those who are:
Hypothermia occurs when more heat is lost than the body can generate. It is usually caused by extended exposure to the cold.
Common causes include:
As people develop hypothermia, their abilities to think and move are often lost slowly. In fact, they may even be unaware that they need emergency treatment. Someone with hypothermia also is likely to have frostbite.
The symptoms include:
Lethargy, cardiac arrest, shock, and coma can set in without prompt treatment. Hypothermia can be fatal.
First AidCall 911 anytime you suspect someone has hypothermia. Give first aid while awaiting emergency assistance.
PreventionBefore you spend time outside in the cold, do NOT drink alcohol or smoke. Drink plenty of fluids and get adequate food and rest.
Wear proper clothing in cold temperatures to protect your body. These include:
Avoid:
If you have Diabetes or circulatory problems see your doctor regularly and maintain good health habits in order to reduce the risk of blood vessel complications that may put you at risk for hypothermia.

Yes, below 95F is considered hypothermic and can cause cardiac problems.
i was excited, but i was getting hypothermic too.
A temp of 79F is NOT a normal temperature. It would be very hypothermic. The person would need rewarming and critical medical care, if they managed to stay alive.
A lower body temperature, as in a hypothermia situation, will have a significant affect on the electrical activity of the heart which may cause the AED to shock when it is not needed.
'34???' Cold??? It depends on the Temperature Scale, be it Centigrade(NO) , Fahrenheit(Yes) , Reamur(NO), Absolute(Kelvin (K))(Yes). If human body temperature goes this low, it is hypothermic, possibly death from freezing. Human body temperature has a mean at 37 degrees C.

No. Temperature is a measure of the kinetic energy in matter. It is not an element.
cold intolerance
Keeping the rain out of the tents is a good one: also keeping a fire going in the rain. Because weather can change quickly in the mountains, ALL WEATHER gear is A REQUIREMENT. Better safe than dead, hypothermic, or carrying the hypothermic out.
Temperature when rises above 55 degrees F (10 degrees C) is considered running hot. You will feel difficult to run fast at this temperature.
A temperature of 24 degrees Celsius is considered to be a comfortable room temperature for most people. A couple degrees above or below is considered acceptable as well.
