Hello,
In which reference do you want this answer?
Please reply.
Customer: replied 6 years ago.
my friend was found dead outdoors in 15 degrees and I'm wondering if they died from freezing or if they died of a heart attack. in other words, could they have just died from freezing alone?
In case of temperature less then 20 degree & where body temperature falls beneath the 77degree F then death may occur due to cardiac stand still.

Hope this will be helpful.

what does cardiac stand still mean. does the cold stop the heart? my friend was in the cold for approx. 3 hours and found not breathing. I just wondering if the cold killed them or would a heart attack have to also be a cause.
The cold weather is sufficient to lead to IHD due to constriction of blood vessels as may be seen with increase in mortality during the winter -

As your friend was also an overweight person then most probably a longer then 45 minute exposure upto which a human body can accommodate itself at low temperature,had lead to severe decrease in blood supply to heart & death.

Hope this will help you.
