Hot tea has several actual and perceived advantages and hence is well liked throughout the world. Hot tea has medicinal benefits, and provides comfort during a runny nose or sore throat. It contains antioxidants. People also drink tea to de-stress and to help them sleep. Tea is also culturally used as a welcoming drink in many countries, especially India. It has also been suggested that a warm drink is perceived as welcoming. A study by the University of Colorado, Boulder suggested that people who held a warm drink perceived a target person as having a warmer personality.
We also like to consume cold drinks. It is interesting to note that external cooling (through skin) may not be desirable; however, oral cooling is perceived as pleasant. There is a scientific reason for this preference. Cold drinks satiate thirst and cold food (like ice-cream) provides oral cooling and are thus considered pleasant. The cold receptors in our mouth are not involved in temperature regulation, unlike skin receptors, and hence a cold fluid may cause discomfort when applied to the skin while still being desirable when consumed.
