Causes. Unlike frostbite, trench foot does not require freezing temperatures; it can occur in temperatures up to 16 °C (61 °F) and within as little as 13 hours. Exposure to these environmental conditions causes deterioration and destruction of the capillaries, and leads to morbidity of the surrounding flesh.

When to be concerned, and how to treat it Once the wind chill makes the temperature feel like –28 or colder, exposed skin can freeze in under 30 minutes. When it drops to –40, frostbite can occur in less than 10 minutes. Take it to –55, and you're in danger within two minutes.

Hypothermia can develop in as little as five minutes in temperatures of minus 50 degrees Fahrenheit if you're not dressed properly and have exposed skin, especially the scalp, hands, fingers, and face, Glatter explained. At 30 below zero, hypothermia can set in in about 10 minutes.

Frostbite will kick in in under 30 minutes when it's 5 degrees and the wind's blowing at 30mph (producing a "feels like" temp of -19 degrees). Generally speaking, it'll take hours -- if at all -- for frostbite to kick in when the temperature is 10 degrees or higher, no matter the wind speed.
