When high humidity combines with high heat, it becomes difficult for the body to lose enough heat to stay within its tolerance limits. When humidity is high, the air feels warmer because the body's way of losing heat, sweating, is hindered as a result of the perspiration not evaporating as quickly in the moist air.

Sherbet is a frozen mixture of sweetened fruit juice and water.
It can also contain milk, egg whites or gelatin. Sorbet is the French word for sherbet. Sorbet differs from sherbet in that it never contains milk and has a softer consistency than sherbet. Gelato is the Italian word for ice cream. It doesn't contain as much air as American ice cream and therefore it has a denser texture.
