When it’s hot, people want colder and lighter foods more; when it’s cold, they crave warmer and fattier foods—even if they don’t eat more overall.

Hot and cold rooms change what kinds of food you crave, but they don’t make you worse at tasting or smelling food.

When it’s hot, people eat more cold dishes and drinks; when it’s cold, they eat more hot, hearty meals—even if they don’t eat more calories overall.

Even though your body feels different in hot or cold rooms, you don’t feel hungrier or less hungry—your appetite stays the same.

Spending a full day in very hot or very cold rooms doesn’t make people eat more or less food overall, even though their bodies react to the temperature.
