Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. [2] Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion.
Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate. Hypothermia can set in when the core temperature drops to 35 °C (95 °F). [2] Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F).
Cycling has a low carbon-emission and low environmental footprint. A European study of thousands of urban dwellers found that daily mobility-related CO 2 emissions were 3.2 kg (7.1 lb) of CO 2 per person, with car travel contributing 70% and cycling 1% (including the entire lifecycle of vehicles and fuels).
Colder temperatures cause the air inside a vehicle's tires to compress, lowering the air pressure.
Cold injury (or cold weather injury) is damage to the body from cold exposure, including hypothermia and several skin injuries. [6] Cold-related skin injuries are categorized into freezing and nonfreezing cold injuries. [5] Freezing cold injuries involve tissue damage when exposed to temperatures below freezing (less than 0 degrees Celsius).

According to The Guardian, scientists have traced this top cold-weather myth to a United States Army manual from the 1970s recommending a hat in the cold because "40 to 45 percent of body heat" is ...
A 2001 NHTSA study found that 40% of passenger cars have at least one tire under-inflated by 0.4 bars (6 psi) or more. [1] The number one cause of tire failure was determined to be under-inflation. Drivers are encouraged to make sure their tires are adequately inflated at all times.
