What are tanning beds and how do they work?
MERICAN Introduction to Tanning Beds
Tanning beds emit ultraviolet (UV) radiation to darken the skin artificially, simulating the effects of natural sunlight. They are commonly found in tanning salons, gyms and spas, and some people buy them for home use.
MERICAN How do tanning beds work?
Tanning beds use fluorescent lamps that emit controlled amounts of UVA and UVB rays, which stimulate melanin production in the skin, resulting in a tan.
1.The Science Behind Tanning
☑ When UV rays penetrate the skin, they trigger melanocytes (pigment-producing cells) to produce melanin, the substance responsible for skin colour.
☑ UVA rays (320–400 nm) penetrate deeper into the skin, oxidising existing melanin to create a quick but temporary tan.
☑ UVB rays (290–320 nm) affect the outer layers of the skin, stimulating the production of new melanin for a longer-lasting tan, but also increasing the risk of sunburn.
2. Types of Tanning Beds
Tanning beds vary in strength and design.
☑ A. Low-pressure tanning beds
These use fluorescent bulbs that emit 95–99% UVA and 1–5% UVB.
They provide a gradual tan and carry a lower risk of burning.
They are common in most tanning salons.
☑ B. High-pressure tanning beds
These use quartz bulbs that emit mostly UVA with minimal UVB.
They produce a deeper, longer-lasting tan in shorter sessions.
They are often found in premium salons.
☑ C. Stand-up Tanning Booths:
These allow for more even coverage (no pressure points from lying down).
They are typically stronger than horizontal beds.
3. The tanning process
☑ Preparation: Exfoliate and moisturise your skin before tanning (do not use sunscreen, as this blocks UV rays).
☑ Session duration: Typically 5–20 minutes, depending on skin type and bed strength.
☑ Post-tan care: Moisturise to maintain the tan and prevent peeling.
MERICAN Conclusion
Tanning beds work by emitting UVA and UVB rays, which stimulate melanin production and result in darker skin. While they provide a quick tan, they carry significant health risks, including skin cancer and premature ageing. Safer alternatives, such as self-tanning products or spray tans, are recommended.
