In cold weather conditions:

1. Sweat production decreases: This is because your body is trying to conserve heat. Sweating cools the body down, so when it's cold, your body naturally tries to reduce this function to keep you warm.

2. Blood supply to the skin decreases: This is a process called vasoconstriction. When it's cold, the blood vessels near the surface of your skin constrict to limit the amount of hot blood that can reach the skin, where it would cool down. Instead, more blood flows to your vital organs to keep them warm.

3. There is greater loss of heat by radiation: This is because the temperature difference between your body and the environment is greater when it's cold. This means that heat will flow from your body to the environment more quickly.

4. Blood supply to the skin increases: This statement is incorrect. As mentioned above, in cold conditions, the blood supply to the skin actually decreases to conserve body heat.
