During these hot summer months primates, like humans, need to keep cool. Like humans, primate have sweat glands and so are able to sweat to keep cool. They are also partial to cold drinks to keep cool, as well as chilled fruit but ice cream can be harmful to them. Some zoos and wildlife sanctuaries will freeze the primates favourite food for them to eat to keep cool.
Most primates cannot swim but will play in shallow water.
