Because it does. Wahey, wasted your time! Hahaha Bob the Builder.
when a liquid evaporates,it gives its latent heat of vaporisation.if no heat is supplied from outside this results in cooling.
Cooling or Heating First of all we have 3 phases, Gas, Liquid and Solid to change from gas to liquid to solid, cooling is required and to change from solid to liquid to gas, heating is required This type of heat is called latent heat, always think of water as an example Ice --> Water , heating Water--> Water Vapour, more heating
When water evaporates, it draws a lot of energy called latent heat of vapourization. It is this demand for energy from evaporating water that causes a cooling effect as it absorbs heat energy from its surroundings.
evaporative cooling
of the release of latent heat
The latent heat of evaporation.

Cooling Load is the amount of energy that is to be extracted from a house to develop a conditioned environment. There are two types of cooling loads i.e, sensible cooling load and latent cooling load.... Heating Load is the amount of heat that is to be supplied to a house in order to increase its temperature to maintain desired temperature...
Sweating has a cooling effect due to the latent heateffect of the evaporation of water. Although sweat is not completely composed of water, water from sweat evaportates at the skin's surface. The latent heat effect means that energy in the form of heat is released from the body when the water from sweat evaporates into the atmosphere on one's body.

Evaporation has a cooling effect... sweat is liquid which means it could evaporate... if it evaporates then it will have a cooling effect :D
It uses sun heat and not chemials
evaporative cooling
of the release of latent heat
cooler works on the principle of evaporative cooling. Evaporation is the process of converting liquid in to vapour . In this process some part of heat is absorbed and stored (latent heat) resulting in decrease of temperature. We can feel this effect in our daily lives , like sweating in summer gives us cooling effect to body
