Question

What happens when the temperature of the body drops due to external cold?

Answer 1

A temperature is a physical number that describes how hot or cold something is. When a body comes into contact with another that is colder or hotter, it is the manifestation of thermal energy, which is present in all matter and is the cause of the occurrence of heat, a flow of energy. The ability of your body to produce and remove heat is measured by its temperature.

Complete answer:
You've probably heard that the average human body temperature is 98.6 degrees Fahrenheit. However, a "normal" body temperature can vary anywhere from 97 to 99 degrees Fahrenheit. It is lower in the early days and rises during the day. It reaches its highest point in the late afternoon or evening, fluctuating by 1 or 2 degrees.

The following factors influence normal body temperature readings:
- A person's age and gender
- The time of day, with activity levels typically lowest in the morning and highest in the afternoon
- High or low activity levels
- Food and fluid intake
- For females, the stage in their monthly menstrual cycle
- The method of means, such as oral (mouth), rectal (bottom), or armpit readings

Vasoconstriction of lib blood vessels and skin is a key element of protection in this situation. This lowers the surface temperature, creating a barrier between the outer environment and the core temperature. Similarly, as the temperature rises, blood flow increases, increasing the likelihood of loss by evaporation and radiation. Shivering to enhance heat generation and constriction of blood vessels in the skin and periphery are the two primary adaptations to cold. This helps to reduce heat loss via the skin and so directs blood to vital interior organs.

Note: A fever is a rise in body temperature that occurs temporarily as a result of a disease. A fever is an indication that our body's cells are battling and destroying a variety of illnesses. Fever is a term that refers to a higher-than-normal body temperature that can affect both children and adults. A fever in an adult might be unpleasant, but it is rarely dangerous until it reaches 39.4° C (103° F) or higher. Mildly elevated body temperatures in toddlers and babies can indicate a severe illness.
