Hot drinks hold a special place in our hearts. Heat improves digestion by lubricating food on the way down. It hydrates, just like cool water, but less energy is required to heat it up to body temperature. Ingesting warm food & drinks is calming, just like taking a warm bath as it opens up blood vessels (vasodilation). Studies have shown that people are more likely to be more sociable and less anxious just by holding a hot drink.
