That's called hypothermia and it's a real danger. Death can happen faster if you fall through ice into freezing water below. Watch first for frostbite. It only takes 5 to 10 minutes in freezing temperatures with a wind chill factor.
Can frostbite kill you?

How cold can a human survive?
At an internal temperature of 95 degrees, humans can experience hypothermia, shivering and pale skin. At 86 degrees, they become unconscious and, at 77 degrees, cardiac arrest can occur. Most people cannot survive if their core temperature drops to 75 degrees .
At what temperature will a human freeze to death?
At a core temperature of 91 F (33 C), a person can experience amnesia; at 82 F (28 C) they can lose consciousness, and below 70 F (21 C) , a person is said to have profound hypothermia, and death can occur, Sawka said. In other words, death strikes long before the body actually freezes.
