Indoor Tanning, Diet, and Exercise: The 2019 Behavioral Review
Discussions around tanning often focus exclusively on ultraviolet exposure, but researchers have increasingly turned their attention to the broader lifestyle routines that accompany tanning booth use. People rarely make health or appearance decisions in a vacuum. Instead, habits such as working out, playing organized sports, monitoring weight, and altering skin tone frequently cluster around shared personal goals. To understand how these patterns intersect, researchers conducted a comprehensive analysis examining physical activity, body composition measures, and nutrition patterns alongside ultraviolet booth visits.
2019: Synthesizing Evidence in the Journal of Behavioral Medicine
In 2019, the Journal of Behavioral Medicine published a dedicated paper titled The relationship between indoor tanning and body mass index, physical activity, or dietary practices: a systematic review. Supported by extramural funding from the National Institutes of Health, this paper operated as one systematic review designed to synthesize available scientific literature. Rather than testing a new group of patients in a clinical trial, the authors evaluated published observational datasets to identify consistent behavioral trends.
The review adhered to PRISMA reporting guidelines to locate and screen relevant papers. By following this standardized protocol, the investigators aimed to document how artificial tanning frequency associates with lifestyle decisions that influence body image, body mass index, and daily health routines.
September, 2003 to May, 2017: The Literature Scope
The authors established a clear timeframe for their investigation, searching PubMed for qualifying papers published between September, 2003 and May, 2017. To qualify for analysis, papers needed to provide specific data connecting indoor tanning with at least one of three primary lifestyle parameters:
- Body mass index (BMI) calculations
- Physical activity habits or participation in athletic sports
- Dietary habits and active weight control strategies
By screening publications over this window, the review captured over a decade of behavioral health surveillance, providing a detailed snapshot of how artificial tanning patterns overlap with routine physical habits.
Sixteen Publications: Structured Evidence and Clear Study Limits
Following their systematic PubMed search and strict screening under PRISMA rules, sixteen publications met the final inclusion criteria. When interpreting this evidence, readers should carefully consider the inherent design and boundaries of the review. This was one synthesis of sixteen observational studies, meaning the data demonstrate statistical correlations rather than cause-and-effect relationships.
The analyzed publications relied heavily on survey responses and self-reported behaviors, which can introduce reporting variations. Additionally, because the sixteen publications examined diverse groups with varying assessment methods, findings must be interpreted cautiously without assuming that indoor tanning directly causes dietary changes or exercise routines.
High Physical Activity and the Aesthetic Motivation Paradox
A central finding of the systematic review was the significant positive relationship between indoor tanning and elevated physical activity. Individuals who used tanning facilities were significantly more likely to engage in rigorous exercise routines and participate in organized sports. At first glance, combining intense fitness with artificial ultraviolet exposure presents a paradox: individuals invest significant effort into cardiovascular fitness while simultaneously exposing their skin to known radiation hazards.
The authors highlighted that these overlapping behaviors frequently stem from shared psychological drivers. Despite turning to hazardous practices, individuals often act out of a strong desire to look attractive, feel fit, or present a healthy appearance. Unfortunately, aesthetic goals can lead people to overlook the established medical evidence on tanning beds and UV risks. In some fitness circles, this drive extends to unapproved tanning injections like melanotan II, which are unregulated products sold illicitly online without medical oversight or safety testing. Choosing safer pathways, such as dermatologist-guided skin care or topical sunless tanning alternatives, allows individuals to address cosmetic preferences without accepting avoidable tissue harm.
One Study: Frequent Tanning and Exercise Addiction Signals
When researchers evaluated the frequency of salon visits, deeper behavioral clusters became evident. Across most of the analyzed literature, frequent or dependent indoor tanning was associated with unhealthy dietary practices. These included extreme weight control measures such as fasting, self-induced vomiting, and the misuse of laxatives or steroids.
Furthermore, in one study captured by the review, frequent or tanning-dependent behavior was specifically tied to a measurable risk for exercise addiction. This indicates that for a vulnerable subgroup, tanning is not an isolated cosmetic hobby. Instead, it can represent one component of a broader pattern of compulsive physique management, where dietary restriction, excessive training, and skin darkening converge around rigid body standards.
Mixed Results: Evaluating the Body Mass Index Metric
While the relationships between tanning, athletics, and diet revealed clear positive associations, the findings for body mass index were far less definitive. The review reported mixed results for BMI across the sixteen analyzed papers. Some datasets suggested correlations between tanning and specific body weight ranges, while others showed no statistically meaningful connection.
These mixed outcomes reinforce why researchers urge caution when drawing conclusions about weight metrics alone. Because athletic individuals often possess higher muscle mass, standard BMI figures can produce inconsistent readings across active populations. The authors concluded that their findings should help inform future behavioral research and assist clinicians in designing targeted interventions for individuals who combine tanning with risky weight control practices.
