Science has unquestionably supported the psychological and physical benefits of non-sexual touch, and there have been numerous studies done on the matter.
These studies have proven that infants will die if they are not held or touched very often. Children who are not touched enough grow up to have intimacy issues. Adolescents who still receive physical and verbal affection from their parents often do not seek out that affection elsewhere, and are less likely to have sex at an early age - Which means less teen pregnancies.
Why, in our adulthood, would we grow out of the need to be touched?
Touch can convey closeness, warmth, concern, or encouragement. It has been shown to decrease stress, promote good sleep habits, and increase sexual desire between partners. Some studies have even gone so far as to say that touch can prevent cancer and other major illnesses.
With all of these benefits, why not give it a try for yourself, and then decide if cuddling is for you?
