Frostbite is freezing of the skin and body tissues just under the skin. It can occur when part of your body is exposed to temperatures or wind chills at or below freezing.
It is important to protect the body and skin from frostbite as one could lose a finger if it is subjected to frostbite. The cold weather impacts on the circulation of the body.

Frostbite
To prevent frostbite during cold weather activities, it is important to dress warmly in layers, cover exposed skin, wear insulated and waterproof clothing, and keep moving to maintain circulation and body heat. It is also important to stay hydrated and avoid prolonged exposure to extreme cold temperatures.
Frostbite would be an example of a harmful effect of being in the cold for to long or misusing a product that can create freezing or below temperatures.
Hypothermia and frostbite.
In extreme cold or when the body is exposed to cold for long periods, this protective strategy can reduce blood flow in some areas of the body to dangerously low levels. The combination of cold temperature and poor blood flow can cause severe tissue injury by freezing the tissue. Frostbite is most likely to happen in body parts farthest from the heart, and those with a lot of surface area exposed to cold. The initial stages of frostbite are sometimes called "frostnip". Mountains or high altitudes with snow are most dangerous to cause frostbite.
Frostbite is an example of both the cold and wind combined.
"When people are in cold weather, typically 5 degrees F (-15 C) and below, the skin's blood vessels narrow." This means less oxygen to the body part, which can lead to cell death and frostbite. (from related link)
To prevent frostbite in cold weather conditions, it is important to dress warmly in layers, covering all exposed skin, wear insulated and waterproof clothing, and protect extremities like hands and feet with gloves and warm socks. It is also important to stay dry and avoid prolonged exposure to cold temperatures. If experiencing symptoms of frostbite, seek medical attention immediately.
High humidity in cold weather conditions can make individuals feel colder than the actual temperature because moisture in the air can cause heat to escape from the body more quickly. This can lead to increased risk of hypothermia and frostbite.
Since blood heats the skin, and in the cold the body wants to keep the core warm, it reduces circulation to the extremities which can cause frostbite.
