low room temperature and negative feedback

## 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.
