Being with friends is so heartwarming, akin to the experience of feeling warm inside a quilt, a new study has revealed.
Scientists found people felt up to 2C (3.6F) warmer when standing 2ft away from someone they were emotionally close to, and colder when they were with a person who did not share the same interests.
Hans Ijzerman, from Amsterdam's VU University said that people put in a warmer room made them feel closer to the questioner - an opposite effect of the study.
"The theory is that the way we perceive relationships is affected by very basic factors. For example, when a baby is touched by its mother that warmth is associated with comfort," The Daily Mail quoted Ijzerman as saying.
"We are now looking at whether social and emotional closeness make a difference to body temperature," he added.
