Can an ice pack give you frostbite?
Putting ice or any kind of chemical cold pack—homemade or otherwise—directly on the skin can lead to frostbite in minutes. Ice crystals form in the skin cells and blood flow slows, depriving the tissues of oxygen. As it progresses, the ice burn causes permanent damage to your skin and underlying tissues.

Cold weather can put increased stress on our cardiovascular system. Cold temperatures cause your blood vessels to constrict, shallow breathing, and a slight thickening of the blood. These changes can cause chest pain in people with heart disease.
What temperature is fatal to humans?
The heat-regulating mechanisms of the body eventually become overwhelmed and unable to deal effectively with the heat, causing the body temperature to climb uncontrollably. Hyperthermia at or above about 40 °C (104 °F) is a life-threatening medical emergency that requires immediate treatment.
