A kiss sets in motion 146 muscles, including 34 facial muscles and 112 postural. Will not be surprised, therefore, to find that kissing for a minute burns 26 calories.
With a kiss they are released the same neurotransmitters (chemical messengers in the brain) than those that are released when you are very concentrated or under the influence of stimulants.
The body experiences a rise in chemicals including oxytocin, dopamine, serotonin and adrenaline — the stuff that creates a feeling of euphoria, attachment and excitement.
Oxytocin is a major one and is sometimes called the “love hormone.” It is responsible for the sense of attachment. Scientists believe that it can keep love alive.
This causes fast heart beat and breathing becomes deep and irregular. As time goes on kissing lowers stress levels, making us feel safe. The longer you are with someone, the more these levels will drop.
