The cardiovascular system has to suddenly adjust its rate to keep the body warm enough. If your heart is weak, it may not be up to the task and a heart attack is possible.
It might be fine for young people and people with people with peak cardiovascular health, but for older people or anyone with impaired cardiovascular health, the risk goes up.
