There's a bizarre phenomenon known as paradoxical undressing which occurs in those suffering from hypothermia - and it's thought to have caused a headache for police in the past.

Hypothermia is a condition that occurs when your body temperature drops to 35°C or lower, and if left untreated, it can cause the body to completely shut down.

According to the NHS, some of the symptoms of the condition include; shivering, slurred speech, slow breathing, tiredness or confusion and pale and cold skin.
