Lowering of body hair
The hair erector muscles in the skin relax and the elasticity of the skin causes them to flatten against the body. This reduces the thickness of the insulating layer and allows more heat to be lost to the environment when the internal temperature is higher than the external temperature.
Increased sweating
To evaporate water from the skin surface requiresenergy in the form of heat. In relatively hairless mammals, such ashumans, sweating is a highly effective means of losing heat.

How do humans lose heat in response to a warm environmentThe methods by which heat is lost from the skin to the external environment occur via radiation, conduction, convection, and evaporation. Heat loss via radiation occurs in the form of infrared rays and accounts for approximately 60% of total body heat loss
The pancreas has key roles in maintaining normal blood glucose levels by producing and releasing insulin and glucagon
Adrenaline. Adrenaline (also known as epinephrine) is a hormone produced in the adrenal gland. It is released when the body is under acute stress or during exercise. It increases blood flow to the skeletal muscles and the level of glucose in the blood.
