Do not warm up by massaging the victim's extremities: The arms and legs of the person experiencing hypothermia to avoid promoting cold blood back to the heart, lungs, and brain. This will cause central hypothermia and additional pressure on the organs which is very dangerous, which can be fatal.

Do not use stimulants: Do not allow people with hypothermia to drink alcohol or smoke because they can interfere with circulation as well as the necessary body warming process.

Do not use vasopressors: For medical staff, when giving first aid, do not use vasopressors to avoid obstructing the circulation, which can easily lead to pulmonary edema.
