Next to each factor listed below, write “increase,” “decrease,” or “same” based on how you expect that factor to affect body temperature.

Raising air temperature: Increase (body temperature will increase)
Sweating: Same (sweating helps in cooling down the body)
Lowering air temperature: Decrease (body temperature will decrease)
Shivering: Increase (shivering generates heat to warm up the body)
Adding clothing: Same (adding clothing helps in maintaining body temperature)
Exercising: Increase (exercise increases body temperature due to increased physical activity)
To determine how each factor would affect body temperature, we need to understand the mechanisms involved.
1. Raising air temperature: Increase - When the air temperature rises, it can increase the body's temperature through conduction and convection. The body absorbs heat from the hotter surroundings, causing its temperature to rise.
2. Sweating: Decrease - Sweating is the body's mechanism to cool down. When we sweat, the moisture on our skin evaporates, taking heat away from the body. This evaporative cooling leads to a decrease in body temperature.
3. Lowering air temperature: Decrease - Lowering the air temperature helps remove heat from the body. As the cooler air surrounds the body, it absorbs heat from the body through conduction and convection, resulting in a decrease in body temperature.
4. Shivering: Increase - Shivering is an involuntary muscle reflex that generates heat. When we shiver, the rapid contractions of the muscles produce heat as a byproduct. This helps increase body temperature in response to cold temperatures.
5. Adding clothing: Same - Adding clothing provides insulation and can help retain body heat in colder temperatures. It acts as a barrier to prevent heat loss through conduction, convection, and radiation. However, it doesn't directly affect the body's ability to generate or dissipate heat.
6. Exercising: Increase - Exercise increases body temperature. When we work out or engage in physical activity, our muscles generate heat as a result of metabolic processes. This rise in body temperature is due to increased metabolic activity, increased blood flow, and increased heat production.
It's important to note that individual responses to these factors may vary based on factors like age, health conditions, and personal comfort levels.
