by means of vasodilation, particularly those near the surface of the body. when the blood vessels dilate, this allows more blood close to the surface where heat is lost from the body.
no
The most body heat is lost through the head, followed by the hands and feet.
It allows body to lose heat by sweating
The body can lose heat through radiation by emitting infrared radiation from the skin. It can also lose heat through conduction by coming into direct contact with cooler surfaces, transferring heat to those surfaces. Additionally, heat can be lost through convection when air or water makes contact with the skin and carries heat away as it flows past the body.
Food
mainly through you skin and breathing.
Heat will naturally flow from hotter objects to colder objects. If heat flows OUT OF your body, you will LOSE that heat energy (thermal energy).

Your body burns calories to keep itself at the optimum temperature of 98.6 degrees Fahrenheit. When you are in the cold, your body burns more calories, but the cold air cools your skin and you lose heat.
The majority of body heat is lost through the head, as it has a high surface area and is often left uncovered.
You lose most of your body heat through your head. This is why cold-weather places often have extreme solutions to keep the head warm such as a scarf, scull cap, or fur headresses.
Losing body temperature or low body temperature is called hypothermia. if the water was colder than your body, your body can rapidly lose heat.
