What is a tan? A tan is a darkening of the skin caused by exposure to ultraviolet (UV) rays from the sun or artificial sources like tanning beds. It occurs when UV radiation causes melanin production to increase, resulting in a change of skin color.
How do you get a tan? You can get a tan by spending time in the sun without sunscreen, allowing UV rays to darken your skin. Tanning can also occur in a tanning bed, which emits UV radiation to produce a tan. Applying self-tanning or bronzing products to the skin, which react with amino acids to stain the skin darker, can also give the look of a tan without UV exposure.
What is considered a light tan? A light tan is a subtle darkening of the skin that gives it a sun-kissed glow without much visible change in skin tone. It can be achieved through limited sun exposure or lower-dose tanning sessions. Light tans produce a healthy appearance without highly noticeable color change.
Skin Tone and Tanning
The way tanning presents on your skin depends on your natural skin tone. People with very fair or pale skin that rarely tans will show a high contrast before and after tanning. Medium skin tones will exhibit a more moderate difference, while those with darker complexions may only show subtle signs of tanning.
Tanning intensity also varies by ethnicity. Those with higher concentrations of melanin naturally in their skin will tan more easily. African-Americans generally tan better than Caucasians, who may burn more readily before slowly tanning. Skin type can also influence tanning ability. Type I (pale white skin) shows the least tanning response, while Type VI (dark brown or black skin) shows the most intense tanning.
Depth of Tan
When you tan, melanin pigment produces different shades depending on how deep in the skin it is deposited. A light tan occurs from melanin higher up in the epidermis, imparting just a hint of color. A medium tan comes from pigment deposited slightly deeper. The deepest, darkest tans happen when UV rays penetrate to the lowest basal layer of the epidermis, where the most melanin is generated.
This is why exfoliating before tanning helps produce deeper, darker results. Removing the surface layer of dead skin cells allows UV rays to travel further into the skin rather than being absorbed superficially. The depth of color also explains why tans fade as skin regenerates; new epidermal skin cells have less underlying melanin pigment.
UV Rays for Tanning
There are two types of ultraviolet (UV) rays that interact with skin – UVA and UVB. UVB rays, which have shorter wavelengths, affect the outermost layers of skin and are responsible for sunburn. UVA rays, with longer wavelengths, penetrate to the deepest layers and are what stimulates melanin production and tanning.
Most tanning beds emit mainly UVA rays, in concentrations many times higher than what comes from the sun. This enables fast tanning, but also carries increased skin cancer risks from overexposure due to deeper skin penetration. Smart tanning involves gradual UV exposure to optimize melanin darkening while minimizing burn risks.
Indoor Tanning vs. Outdoor Tanning
Both indoor tanning in beds and outdoor tanning in the sun involve exposure to UV rays that trigger melanin production and skin darkening. However, there are some key differences:
UV composition – Outdoor sun exposure contains a mix of UVA and UVB rays, while indoor beds deliver concentrated UVA.
Exposure control – Tanning beds allow controlled timing and dosage, while outdoor tanning depends on variable conditions like time of day, location and weather.
Effects – Outdoor tanning can burn the skin if overdone, while tanning beds rarely cause burns due to the dominance of UVA rays. Both can potentially lead to skin cancer with excessive use.
Convenience – Tanning beds offer scheduling convenience and availability regardless of weather or season. Outdoor tanning depends on cooperative weather and daylight access.
Cost – Tanning salons charge by the session, while outdoor tanning in the sun is free. However, travel costs may be involved to reach optimal outdoor tanning locations.
Gradual Tanning
Health experts emphasize the importance of gradually building up a tan rather than intensely tanning all at once. Going for a dark tan too quickly can cause painful sunburns and increase skin cancer risks down the road.
With new exposure, the skin needs time to ramp up melanin production and natural protection against UV damage. Starting with short, infrequent sessions and increasing duration over several weeks enables adaptation without shocking the skin. This approach maximizes the aesthetic tanning results while providing a healthy balance of UV exposure.
When is Tanning Season?
While indoor tanning can happen year-round, most people associate tanning with the spring and summer seasons. In the northern hemisphere, the optimal outdoor tanning period is from April through September. Peak solar intensity occurs from June to August, making these mid-summer months the most efficient for tanning, though also the highest risk for overexposure if not careful.
Late spring and early fall offer milder UV conditions suitable for gradual tanning. Cooler months with less direct sunlight make tanning much slower and more difficult. For winter outdoor tanning, tropical destinations provide the best opportunity thanks to high UV indexes year-round near the equator.
Tanning Safety Tips
To tan responsibly, experts recommend:
– Gradually build up exposure time to avoid burning
– Apply broad spectrum sunscreen to face and sensitive areas
– Avoid peak midday sun when UV rays are strongest
– Wear protective lip balm and UV-filtering sunglasses
– Hydrate skin before and after tanning sessions
– Choose reputable salons and sanitize tanning beds
– Limit sessions to 10-15 minutes at first
– Listen to your skin and stop if burning occurs
– Allow 48 hours between sessions for skin to recover
– Consult a dermatologist if concerned about skin changes
Who Should Avoid Tanning?
Certain people are advised to avoid intentional tanning activities altogether:
– Minors under 18 years old
– Those with very fair skin that always burns easily
– Individuals with a history of skin cancer
– People taking medications that increase sun sensitivity
– Those with medical conditions aggravated by heat or sunlight
– Pregnant women
– Those with recent tattoos or piercings
– People with widespread moles or atypical moles
– Those with a family history of melanoma
– Anyone with sun allergies or autoimmune disorders
– Recent surgery patients
– Anyone with open sores or wounds
These individuals are at increased risk of negative reactions to UV light and would benefit most from practicing safe sun habits and using alternative bronzing methods like spray tans and self-tanners.
Signs of Too Much Tanning
It’s important to tan carefully to avoid overdoing it. Signs you’ve had too much UV exposure and need to cut back include:
– Burning, stinging or tightness on the skin
– Blistering, peeling, flaking or shedding skin
– Severe redness and/or swelling
– Headache, dizziness or feeling faint
– Nausea or vomiting
– Fatigue, lethargy or weakness
– Dehydration
– Fever or chills
– Skin rash or hives
These symptoms indicate you should get out of the sun and seek medical treatment if they are severe.
How Long Does a Tan Last?
A tan can last anywhere from a few days to a few weeks, depending on factors like your skin tone, depth of tan and how diligently you keep it up. Fair skin shows tanning effects for the shortest duration, just 4-7 days in many cases. Medium skin tones can retain a tan for 2-3 weeks, while olive and dark complexions may stay noticeably tan for 3-4 weeks.
Ongoing exposure is needed about every 2 weeks for lighter skin and 3-4 weeks for darker skin to maintain color. Use of moisturizers and self-tanners can also prolong the appearance between UV tanning sessions. A tan will inevitably fade though as new skin layers form and melanin diminishes closer to the surface.
| Skin Type | Tan Duration |
|---|---|
| Fair/Pale | 4-7 days |
| Medium | 2-3 weeks |
| Olive/Dark | 3-4 weeks |
Best Time of Day to Tan Outdoors
While the sun’s rays are needed for tanning, the timing of exposure makes a difference. The best time of day to tan outside is usually mid-morning to early afternoon, around 10am to 2pm.
UV intensity peaks around the solar midday, so closer to noon maximizes tanning efficiency while morning and afternoon provide gentler exposure better for gradual building. Avoiding the strongest midday sun will help prevent burning as well. Late afternoon sun also works, though the angles make tanning occur more slowly.
Also consider the time of year, as the sun sits at higher angles during the summer. Adjust timing accordingly – earlier in the day during winter and later in the day during summer. Know your skin’s limits and don’t overdo the length of exposure at peak hours. The optimal tanning time balances efficient UV absorption with lower burning risk.
Best Practices for Avoiding Sunburn While Tanning
Trying to tan while avoiding sunburn can be tricky, but these tips can help:
– Gradually build up tan time – don’t go for maximum exposure at first
– Avoid midday peak sun when UV rays are most intense
– Check the UV index for that day’s burn risk level
– Apply sunscreen of at least SPF 30 to face and sensitive spots
– Wear protective clothing like hats, sunglasses and coverups
– Seek shade during the most intense sunlight hours
– Hydrate skin before and after sun exposure
– Use moisturizing products to soothe skin before tanning
– Refresh sunscreen frequently during extended time outdoors
– Watch for early redness or burning sensations and get out of the sun
– Allow skin to cool and recover between successive tanning sessions
The key is increasing exposure time slowly from session to session based on your skin’s tolerance and using other precautions to moderate sun intensity. Be diligent about sunscreen and hydration, and pay attention to how your skin responds.
Is It Better to Tan Naturally or in a Tanning Bed?
There are pros and cons to both natural and artificial tanning. Some key factors to consider:
– Natural sunlight provides a broader spectrum of UV rays, leading to better vitamin D production in the skin. Indoor tanning beds emit mostly UVA rays.
– Outdoor tanning depends on weather, season and time constraints, while tanning salons offer year-round availability and scheduling control.
– There is ongoing debate over which type leads to longer-lasting color. Both can fade within weeks for lighter skin tones.
– Tanning outdoors raises the risk of uneven burns, tan lines and exposure to insects and allergens. Indoor tanning avoids these issues.
– Overexposure is more likely outdoors due to variable conditions. Tanning beds allow precise timing and dosing to prevent burns.
– While excessive use of either method carries risks, some research suggests indoor tanning may be linked to higher incidence of skin cancers.
There are reasonable arguments on both sides. In the end it comes down to personal preference, lifestyle factors and convenience. Moderation and proper precautions are advised with both natural sunlight and artificial UV sources to maximize tanning benefits while minimizing health risks.
