Energy has several forms, such as chemical energy, solar energy, kinetic energy and electromagnetic energy. Heat is one of the most important forms of energy. In the past, it was called heat by liquid or heat. It was believed that this thermal spiral moves from hot materials to cold materials to heat them. Heat is obtained by mechanical effort, chemical reaction, There are three forms of heat transfer from one body to another, and from one center to another, depending on the physical state of matter. The material exists in the universe in three cases, solid state, liquid state and gaseous state.
- Heat transfer by pregnancy: Transmission of pregnancy heat is in the gases and liquids, when the heating of the particles of liquid or gas increases the temperature of the gas or liquid, it expands and reduces its density, which leads to move up and drop the gas or liquid more intense, and the temperature is lower and so on , Resulting in pregnancy currents.
- Heat transfer by conduction: conduction The method of heat transfer in solids, gases and liquids. When the material is heated, the free electrons start to move and thus the atoms vibrate.
- Radiation transfer: The term radiation means energy transmission without the need for a physical medium.
The heat of the human body, in other words, the heat acquired by the human body and the heat lost by the human body, is affected by a combination of factors such as: the physical activity of the person, and the fluctuations of the atmosphere, when exposed to the sun for example or any heat source that leads to an increase in body temperature In the winter or cold weather, the temperature of the body decreases, and if there is an infection in the body, or the presence of microbes and other health problems, raise the temperature of the body, and when the temperature of the human body is almost (38 degrees) Fever, in this case it is necessary to reduce the temperature of the body, especially E. A was suffering from a high temperature children.
Ways to reduce the temperature of the human body:
- Cold water compresses work.
- Take a bath that is not hot.
- Drink plenty of water and fluids.
- Apply cool compresses and put them under the armpit or placed between the thighs.
- Apply compresses to heat the room and place it on the large joints.
- Eat lemon juice.
- Change the room temperature if it is cold.
- Eat plenty of vegetables.
