The claim that tattoos are associated with positive health on the mind does have validity in it. The Guardian article referenced cites Dr. Viren Swami. Swami being a professor at Anglia Ruskin University, his research is strong to support the claims. When looking further at other credible sources such as the International Journal of Dermatology and the National Library of medicine. Research seems to suggest that there is a trend of those getting tattoos, depicting that self-esteem and mental health is improved with/around tattooing. "Immediately after getting the tattoo, both men and women reported reduced anxiety and less dissatisfaction around their appearance, effects that were sustained at 3-wk follow up. On 3-wk follow up, both genders also reported an overall increase in self-esteem. This suggests that tattoos can mitigate negative attitudes a wearer might hold about one’s appearance." ( National Library of Medicine). This was research conducted by Swami ( Marked for life? A prospective study of tattoos on appearance anxiety and dissatisfaction, perceptions of uniqueness, and self esteem), in the study the looked at 82 British residents and their behaviors within the span of getting a tattoo and healing. During this time they measured body appreciation, distinctive appearance investment, self-ascribed uniqueness, social physique anxiety, and self-esteem throughput the process. These articles both show validity in the claim that tattoos have positives effect mentally.
