The purpose is to maintain an acceptable temperature.
the sun is important to the water cycle because without the sun the water wont evaporate.

Temperature and pressure are important factors.
When hot water hits the skin, it causes the water on the skin to evaporate quickly, creating steam. This is because the heat from the water increases the temperature of the water on the skin, causing it to turn into vapor.
Lowering the temperature evaporation is less important.
The skin of lizards is waterproof because it is made of keratin and has no pores to evaporate water. A lizard can not 'sweat', but it dries out less quickly because of the pore-lacking skin.
To suggest that germs evaporate would be to suggest that germs are liquid. Germs are, of course, not liquids, so therefore they cannot evaporate.
Yes, salt can evaporate from water. When water evaporates, it leaves behind the salt, which does not evaporate.
Evaporation of water from the skin is a cooling process because it requires heat energy from the skin to convert liquid water into water vapor. This heat energy is drawn from the skin's surface, resulting in a cooling sensation.
The phenomenon is called perspiration; each liquid has a specific enthalpy of vaporization.
The sweat absorbs the heat from your skin in order to evaporate.
The most important factors are a high temperature and a low pressure.
