When sweat evaporates from the surface of your skin, it removes excess heat and cools you. This is actually due to a neat principle in physics, which goes like this. To convert water from a liquid to a vapor, it takes a certain amount of heat called the heat of vaporization.
Hereof, how does sweating cool you down in terms of particles?
Sweat helps cool you down by releasing moisture onto your skin. But that's not all that's going on. On a hot day, your sweat evaporates from your skin taking a little bit of your body heat with it. So your sweat won't evaporate very much because the humid air can't hold very many more water molecules.
Also, why does the evaporation of sweat cool your body on a warm day? The energy for the sweat to become a gas (evaporate) off your body comes from your body's thermal energy. It uses energy from your body which means there is less heat (thermal energy) on you body so you lose heat and feel cooler.
Consequently, how does sweat evaporate?
The sweat leaves your skin through tiny holes called pores. When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor). As the sweat evaporates off your skin, you cool down.
What happens to your body when u sweat?
Sweating, or perspiring, is how the body regulates temperature—sweat keeps us cool and comfortable and prevents the body from overheating in hot environments or during exercise. Sweat leaves your skin through pores and evaporates when it hits outside air. As the sweat evaporates off your body, you cool down.”

As each gram of sweat transitions from liquid to gas phase, it absorbs 2,427 joules of energy from the body and dissipates the heat into the environment. But if you wipe away the perspiration before it evaporates, that process will get cut short, and you'll need to sweat more just to achieve the same degree of cooling.What happens if your sweat doesn't evaporate?

Why evaporation occurs Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point. Net evaporation occurs when the rate of evaporation exceeds the rate of condensation.Why does your skin feel cold when alcohol is rubbed on it?

An exothermic reaction takes place when heat flows out of a system into its surroundings. When you sweat, the system – your body – cools down as perspiration evaporates from the skin and heat flows to the surrounding area.

Sweating: Your sweat glands release sweat, which cools your skin as it evaporates. This helps lower your internal temperature. This increases blood flow to your skin where it is cooler — away from your warm inner body. This lets your body release heat through heat radiation.What are 5 ways the body loses heat?
Top 5 ways body heat is lost- Evaporation – Body heat turns sweat into vapor.
- Convection – Heat loss by air or water moving across the skin surface.
