Are Tanning Beds Safe?

Tanning beds are not safe. Despite being marketed as a convenient and controlled way to achieve a bronzed look, these devices emit concentrated ultraviolet radiation (UVR)—a known human carcinogen. Just one session can increase the risk of skin cancer, including melanoma, the deadliest form.

Indoor tanning, including sunbeds and solariums, artificially exposes the skin to UV radiation to trigger pigment darkening. While the tanning industry has promoted these devices as safer than natural sunlight, this claim is widely refuted by public health organizations. Persistent myths—such as tanning beds being beneficial for acne, vitamin D production, or as part of a healthy lifestyle—continue to mislead users.

In response, leading authorities including the World Health Organization (WHO), the American Medical Association (AMA), the American Academy of Dermatology (AAD), and the American Academy of Pediatrics (AAP) have called for an outright ban on indoor tanning among minors. The U.S. Food and Drug Administration (FDA) also recommends that no one under 18 should use tanning beds due to their established health risks.^[1],[2]

This article explores the scientific evidence on tanning bed risks, debunks common misconceptions, and outlines safer alternatives for those seeking a tanned appearance.

How Do Tanning Beds Work?

Tanning beds work by exposing your skin to ultraviolet (UV) radiation, which is the same type of radiation found in sunlight. There are two main types of UV rays involved in tanning:

• UVA (Ultraviolet A): Long-wave radiation that penetrates deep into the skin.

• UVB (Ultraviolet B): Short-wave radiation that affects the outer layers of the skin.

Most indoor tanning devices—such as sunbeds, lamps, bulbs, and booths—primarily emit UVA, with a smaller amount of UVB. The intensity of this radiation can be similar to, or even exceed, that of midday sunlight.

When your skin is exposed to UV radiation, it responds by:

• Increasing melanin production, the pigment responsible for skin color, in an attempt to protect against further damage.

• Thickening the outer layer of the skin (especially with UVB), which slightly reduces further UV penetration.

However, this response is not harmless—it’s a sign that damage has already occurred. Both UVA and UVB can alter the DNA in skin cells, increasing the risk of skin cancer. While UVB causes visible sunburn and can lead to delayed tanning, it also provides minor protection by triggering melanin and skin thickening (about SPF 2–3). UVA, on the other hand, penetrates deeper into the skin, causes oxidative damage, and can suppress the immune system. It is also less effective at stimulating protective pigmentation.

This combination of DNA damage, inflammation, and immune suppression contributes to the development of melanoma and other skin cancers—even if no sunburn occurs.^[3],[4]

Tanning beds primarily emit UVA radiation, which penetrates deeper into the skin and may increase cancer risk—sometimes delivering UV levels up to 15 times stronger than the midday sun.

Why Tanning Beds Increase the Risk of Skin Cancer?

Along with substances like plutonium, cigarettes, and solar UV radiation, UV tanning equipment are classified as Group 1 carcinogens by the International Agency for Research on Cancer (IARC), a division of the World Health Organisation (WHO). These devices are also categorised by the FDA as moderate-to-high risk (Class II). Their usage for tanning or any other non-medical purpose is specifically discouraged by the WHO and the International Commission on Non-Ionizing Radiation Protection (ICNIRP).^[2]

Extensive research demonstrates that indoor tanning is directly linked to melanoma, basal cell carcinoma (BCC), and squamous cell carcinoma (SCC), despite widespread beliefs that it does not cause skin cancer. Sunbed use has repeatedly been linked to a statistically significant increased risk of cutaneous melanoma, BCC, and SCC. Unlike fluctuating natural sunshine, prolonged exposure to tanning bed’s concentrated UV radiation greatly raises the risk of skin cancer.

Quantifiable Risks and User Demographics

• Individuals using tanning beds before age 35 increase their risk for malignant melanoma by 75%. One study found that 97% (61 of 63) of women diagnosed with melanoma before age 30 had used tanning beds.^[2]
• Starting indoor tanning before age 20 can increase melanoma chances by 47%, with risk increasing with each subsequent use
• Women younger than 30 are six times more likely to develop melanoma if they tan indoors^[2]
• A history of indoor tanning increases the risk of early-onset basal cell carcinoma before age 40 by 69%. [2]Indoor tanning can increase the risk of developing squamous cell carcinoma by 58% and basal cell carcinoma by 24% ^[1]
• Adolescents who engage in indoor tanning before age 18 are more likely to continue as adults. Over 75% of high school students in the United States who used indoor tanning experienced at least one sunburn.

Broader Health and Economic Implications

• Beyond cancer, excessive UV exposure during indoor tanning can lead to premature skin photoaging, immune suppression, and eye damage, including cataracts and ocular melanoma^[6]
• Frequent, intentional UV exposure may also lead to tanning addiction. Research indicates that over 20% of white women aged 18-30 who tan indoors exhibit indoor tanning dependence
• Indoor tanning imposes a significant financial burden. Over the course of the affected individuals’ lives, an estimated $127.3 billion will be lost in economic losses due to the $343.1 million annual cost of treating skin malignancies caused by indoor tanning. An estimated $31.1 billion USD might be saved by enacting legislation to prohibit indoor tanning in North America (the United States and Canada); limiting it to children would result in around one-third of these savings.^[1]

The Myth of the “Base Tan” and Other Misconceptions

A “base tan” is the early tanning response from UV exposure—often mistaken as protection. But it only provides the same protection as SPF 3—far too low to prevent damage. SPF 30+ sunscreen blocks about 97% of harmful UV rays.

Indoor vs. Outdoor Tanning Safety Myth

• Indoor tanning is not safer than outdoor tanning; it can be more dangerous.
• Indoor tanning devices can emit UV radiation 10 to 15 times stronger than the midday summer sun. The belief that UVA radiation is “safe UVR” is untrue.

The “Base Tan” Myth

• Using a tanning bed for a “base tan” does not prevent later sunburns.
• A “base tan” offers minimal protection, equivalent to an approximate SPF of 3, which is largely ineffective.
• Any tan indicates DNA damage from UV rays, similar to a sunburn.
• Damaged DNA, whether from sunburn or tan, and regardless of origin (sun or tanning bed), can lead to mutations in skin cells that may result in skin cancer.

Vitamin D Myth

• Sunbed use is not an efficient way to generate Vitamin D
• For most latitudes, very brief sunlight exposure is sufficient for adequate vitamin D synthesis.
• For individuals at high risk of vitamin D deficiency or with very limited solar exposure, oral supplements are an effective, non-carcinogenic way to increase vitamin D levels.

Controlled Exposure Myth

• The tan induced by artificial UVR tanning devices provides little protection against sunburn and solar UVR-induced DNA damage.
• Human laboratory tests have shown this protection is equivalent to a sunscreen with an SPF of only about 3!
• Sunbed users can be exposed to higher UVR doses than anticipated, as many devices emit UVR above safety limits.

Immediate Cosmetic Benefits Myth

• The immediate skin pigment darkening after sunbed UVR exposure may temporarily hide minor imperfections like small wrinkles or spider veins
• This immediate darkening soon fades, and imperfections become visible again, potentially motivating repeated sunbed use, which raises the risk of premature aging and skin cancers.

Good for Seasonal Affective Disorder (SAD) Myth

• While sunbed users may genuinely experience a sense of well-being, this is often linked to feeling more attractive or “healthy looking”. Endogenous brain opioids may be created during tanning, leading to a sense of well-being and the possibility of tanning addiction.
• Visible light exposure, not UV, is a common and recommended therapy for SAD.

Tanning Not Sunburning Myth

• A tan is a sign that the skin has been damaged by UVR and is not a sign of good health.
• Tanning without a sunburn can still cause premature skin aging and increase the risk of skin cancer through irreparable DNA damage.
• Each time skin is exposed to UVR from the sun or a sunbed, the risk of developing skin cancer increases.^[3]

Vitamin D and Tanning Beds — What’s the Truth?

Indoor tanning beds and lamps should be avoided for vitamin D acquisition due to the inherent risk of skin cancer from UV radiation exposure.

It is a misconception that indoor tanning is an excellent source of vitamin D. Tanning beds primarily emit UVA rays, whereas UVB rays are responsible for the skin’s conversion of a protein into vitamin D. Most individuals acquire sufficient vitamin D from incidental sun exposure through brief daily periods outdoors.

For those with vitamin D deficiency, the medical community recommends obtaining vitamin D through a healthy diet that includes naturally rich foods and/or vitamin D supplements. Tanning beds are not a recommended or safe method for managing vitamin D deficiency.^[3]

Who Is Most at Risk from Tanning Beds?

While all sunbed users face a risk of adverse health effects, certain individuals are at a significantly increased risk of harm from UV radiation exposure.

• Young age of exposure
• Women younger than 30 ( six times more likely to develop melanoma if they tan indoors)
• Individuals who tend to freckle or have skin that burns easily.
• Those with a history of childhood sunburn.
• Individuals with a large number of moles (naevi).
• People taking photosensitizing medication.
• Individuals wearing cosmetics.
• Those with a weakened immune system.
• Individuals with a family history of skin cancer.
• People who have ever been treated for actinic keratosis or skin cancer.
• Individuals with pre-malignant or malignant skin lesions.
• Those who have had sun or sunbed exposure within the past 48 hours.
• Indoor tanning-seeking behaviors.

Misconceptions, such as believing a pre-vacation tan safeguards the skin, that sunbeds can treat acne or increase vitamin D, or that tanning is a healthy habit, also contribute to usage.^[4],[5]

Safer Alternatives to Tanning Beds

Individuals seeking a tanned appearance without the harmful effects of UV radiation have several safer alternatives to consider:

Topical Tanning Products

• Spray Tan Booths: try out a tanned appearance without UV exposure. Users should ensure eye and lip protection and avoid inhaling or ingesting the spray. This is an option for individuals who prefer professional application over self-application.
• Temporary Tanning Lotions and Sunscreens: Provide temporary color that lasts up to a day and washes off. Many are available integrated with sunscreens, offering both a tinted appearance and UV protection.

Controlled UV Exposure with Protection

• Brief sun exposure combined with the application of broad-spectrum sunscreen with an SPF of 30 or higher can allow for minimal UV exposure while providing protection.

FAQs – Tanning and Your Skin Health

• Is indoor tanning safer than tanning outdoors?
  No, indoor tanning is not safer than outdoor tanning; in fact, it can be more dangerous.1 Indoor tanning devices can emit UV radiation that is 10 to 15 times stronger than the midday summer sun. Unlike natural sunlight, which varies in intensity, indoor tanning involves continuous and intense UV exposure.

• Can tanning beds cause melanoma?
  Yes, tanning beds can cause melanoma. UV tanning equipment is classified as Group 1 carcinogens by the International Agency for Research on Cancer (IARC), a division of the World Health Organization (WHO), placing them in the same category as substances like plutonium and cigarettes. Extensive research directly links indoor tanning to an increased risk of melanoma, basal cell carcinoma (BCC), and squamous cell carcinoma (SCC).

• How much tanning bed use is dangerous?
  Any use of tanning beds is considered dangerous, as the risk of skin cancer increases with each use, especially when started at a younger age. For instance, individuals using tanning beds before age 35 increase their risk for malignant melanoma by 75%. Research indicates that even people who do not burn after indoor tanning are at an increased risk of melanoma if they tan indoors.

• Can you get vitamin D from tanning beds?
  It is a misconception that indoor tanning is an excellent source of vitamin D. Tanning beds primarily emit UVA rays, while UVB rays are responsible for the skin’s conversion of a protein into vitamin D. Most individuals acquire sufficient vitamin D from brief, incidental sun exposure. For those with vitamin D deficiency, the medical community recommends obtaining vitamin D through a healthy diet, naturally rich foods, and/or vitamin D supplements, as tanning beds are not a safe or recommended method.

• What’s the safest way to look tanned?
  The safest ways to achieve a tanned appearance without harmful UV exposure include using topical tanning products such as spray tan booths, temporary tanning lotions, and DHA-based fake tans.Some temporary tanning products are also incorporated into sunscreens, offering both a tinted appearance and UV protection.
