1) Long kisses are beneficial to our circulatory system. When kissing, our pulse rate is quickening up to 110 beats per minute. This is a great training for our cardiovascular system.
2) After kissing, the lungs work harder, resulting in 60 inhales per minute compared to regular 20 inhales. Such “ventilation” is a good preventive measure against lung diseases.
3) Some dentists believe that kissing is a preventive measure against dental caries. Indeed, kissing stimulates the flow of salvia that eliminates acid coat on the teeth.
