This was a cross-sectional survey study using nationally representative U.S. data from adults. The sample included thousands of women and men (large population-level dataset; exact N in full text) who answered questions about outdoor tanning behavior. Researchers assessed how common intentional outdoor tanning is and which demographic and behavioral factors are linked to it. Primary outcomes were prevalence of intentional tanning and associations with age, sex, indoor tanning, and sun-protective behaviors.
More than one-third of women and roughly one-quarter of men reported deliberately tanning outdoors to change their skin color. Intentional tanning was more common among younger adults and among people who also used indoor tanning beds. Many tanners reported inconsistent sun protection and held beliefs that a tan looks healthier or is protective. These patterns suggest a cluster of behaviors that together increase UV exposure and likely raise lifetime skin cancer risk.
This study is based on self-reported survey answers, which can be affected by memory errors and social desirability bias. The cross-sectional design shows associations at one point in time but cannot prove that intentional tanning causes later health outcomes. Details on UV dose, lifetime exposure, skin type, and exact frequency or duration of tanning were limited. The data may not fully apply to all racial and ethnic groups, outdoor workers, or people outside the U.S., and links to fertility outcomes were not directly studied and remain uncertain.
This study highlights that intentional outdoor tanning is common and patterned by age, sex, and appearance-focused attitudes, not just by time spent outside. The cross-sectional design limits causal conclusions, but the large, nationally representative sample strengthens generalizability to U.S. adults. For reproductive-age patients, frequent UV exposure may add to oxidative stress, DNA damage, and potential endocrine disruption, which are already central concerns in fertility care. The findings align with other dermatology literature showing underestimation of UV risk and support integrating skin and sun-history questions into holistic, restorative assessments.
Ask patients directly if they tan on purpose outdoors, not just whether they “spend time in the sun.” Clarify that any tan is a sign of skin damage, not health, and that repeated burns or deep tans increase future skin cancer risk. For those trying to conceive, frame UV exposure as one piece of total body stress, alongside sleep, nutrition, inflammation, and endocrine health. Encourage shade, clothing, hats, and appropriate sunscreen, while still supporting safe, brief sun exposure for mood and vitamin D as guided by their clinician.
This study found that many adults, especially younger women, still lie in the sun on purpose to get a tan. A tan is your skin’s stress response to UV rays, not a sign of health. Over time, repeated tanning can raise the chance of skin cancer and add to the body’s overall oxidative and inflammatory load. When you are on a fertility journey, your skin health, hormone balance, and immune system are all connected, so your sun habits are worth discussing with your clinician as part of looking at root causes and whole-body wellness.
Screen for intentional outdoor tanning specifically in reproductive-age patients, distinguishing it from incidental sun exposure for work or daily life. Consider tanning behaviors as a marker for broader appearance-oriented risk clusters (indoor tanning, inconsistent sunscreen use) and potential underestimation of cancer risk. In restorative protocols, integrate sun history into assessments of oxidative stress, immune status, and endocrine balance; consider biomarkers such as 25(OH)D, hs-CRP, and, when indicated, oxidative stress markers. Counsel about balanced sun exposure (brief, non-burning exposure for circadian and vitamin D support vs. intentional tanning) and document high-risk histories (frequent burns, tanning plus family history of melanoma) that may warrant dermatology referral.
