Sweating and Heat Loss Investigation

The purpose of the investigation of perspiration and heat loss is to investigate whether the body that sweat is losing faster than the dry body. Equipment Two Boiling Tubes 47ml Up to 2 Weighing Tanks 50ml Max 2 Temperature Meter Paper Towels Boiling Water Till 250ml Water Kettle Stopwatch 2 Magnifying Glass (8 ×) Two Cork Test Racks with Small Hole in the Center Preliminary Work First You need to know the work, the amount of water used, the wetting of the tissue paper with hot water, the reading time, the reading accuracy, the number of readings, and the temperature of the start time.

Latent heat loss is also called heat loss due to evaporation and occupies most of body's heat loss. As the temperature in the center of the body rises, the body stimulates the sweat glands of the skin and brings extra moisture to the surface of the skin. After that, the liquid is converted to steam to remove heat from the body surface. The rate of heat loss due to evaporation is directly related to the vapor pressure of the skin surface and the amount of moisture present in the skin. Therefore, when the skin is completely wet, maximum heat transfer occurs. The body loses moisture by evaporation, but the maximum heat loss occurs while physical activity is increasing.

Sweat glands appear in all skin areas - each with more than 2 million people. When the body needs to lose heat, these glands create sweat (a mixture of some waste products like water, salt and urea). Sweat travels through the sweat duct to the surface of the skin, evaporates from the skin and cools the body.

Exercise increases muscle fever. Cooling your body depends on the evaporation of your skin's sweat. Weight loss of sweat during intense classes and long rehearsals can be as much as 2 liters per hour. Loss of moisture can lead to dehydration, which will affect performance and mental function, make it difficult to quickly learn and execute complex dance combinations. We recommend that you drink 250 ml of liquid every 15 minutes. Whenever a class or rehearsal is interrupted, the dancer should be prepared to come in contact with the liquid, and the mechanism of thirst is not satisfying the need of liquid of the body, so it is encouraged to drink You should. Water bottles and sports drinks should be part of the dancer 's "tools", and possibly dancers should be able to drink bottles of drinks in the studio and theater. After class and rehearsal, dancers should continue to increase fluid consumption over the next few hours. Do not use lots of carbonated drinks or juice
