low room temperature and negative feedback

### If room temperature is suddenly very low, the body begins to lose heat in response. By normal conduction, the body will begin to lose heat. In order to prevent hypothermia, the reduction in the body's temperature will stimulate shivering, causing muscles to contract thereby burning energy. Heat production will be the outcome. The body will also try to reduce the surface area of heat loss. Peripheral blood vessels will begin to constrict, thus reducing the blood going to extremities. This is how frostbite arises. If there is a prolonged constriction of blood vessels, tissues will be damaged.

## Step1: Initial Response to Low Room Temperature### When the room temperature suddenly drops, the body begins to lose heat in response. This is a natural process to maintain the body's core temperature.## Step2: Conduction of Heat### Heat loss occurs through conduction, where heat is transferred from the body to the colder environment.## Step3: Prevention of Hypothermia### To prevent hypothermia, the body reduces its temperature. This reduction stimulates shivering, which is the body's response to cold.## Step4: Shivering and Energy Consumption### Shivering causes muscles to contract and relax repeatedly, which burns energy and generates heat.## Step5: Reduction of Surface Area for Heat Loss### The body tries to reduce the surface area through which heat can be lost. This is achieved by constricting peripheral blood vessels.## Step6: Constriction of Blood Vessels### Peripheral blood vessels constrict, reducing blood flow to the extremities and thus minimizing heat loss.## Step7: Risk of Frostbite### Prolonged constriction of blood vessels can lead to frostbite, as tissues are deprived of oxygen and nutrients.
