Explain thermal stress

WebHeat stress occurs when the body cannot get rid of excess heat. When this happens, the body's core temperature rises and the heart rate increases. As the body continues to store heat, the person begins to lose concentration and has difficulty focusing on a task, may become irritable or sick, and often loses the desire to drink. ...

WebThe thickness of the thermal boundary layer, ઠₜ, is the distance from the surface boundary to the point where the temperature of the flow has reached 99% as the free-stream temperature. For laminar flow, the thermal boundary layer thickness can be expressed as: Note that: Pr is the Prandtl number. ઠᵥ is velocity boundary layer thickness. WebOne reason I can think of is that our body releases hormones when we are in the fasting state. One of those hormones is cortisol, the stress hormone. Prolonged levels of stress have profound negative effects on the body. You may not feel stressed mentally per se, but your body is getting the signal that something is wrong.
