Many people ask how long it takes to tan in a tanning bed compared to tanning in the sun. While both methods rely on ultraviolet (UV) exposure, the time required and intensity differ greatly.
Understanding this comparison can help you better evaluate tanning speed, effectiveness, and potential risks.
Why Tanning Bed Time and Sun Time Are Different
Although both tanning beds and sunlight emit UV radiation, they are not equal.
-
The sun provides a mix of UVA and UVB, with intensity that changes throughout the day
-
Tanning beds emit mostly UVA (about 95–99%) at a controlled but much higher intensity
Because tanning beds deliver concentrated UV exposure, they can produce visible tanning results in less time.
General Time Comparison: Tanning Bed vs Sun
While exact equivalence depends on conditions, a commonly accepted comparison is:
10–15 minutes in a tanning bed ≈ 1–3 hours in strong midday sun
This estimate assumes:
-
Standard commercial tanning beds
-
Midday sun with high UV index
-
Fair to medium skin types
High-pressure tanning beds may deliver even more intense UVA in shorter sessions.
Typical Tanning Time in Each Setting
Tanning Bed
-
Session length: 5–15 minutes
-
Visible tan: after 2–3 sessions
-
Deeper tan: after 5–8 sessions
Sun Exposure
-
Session length: 30–120+ minutes
-
Visible tan: after several days of repeated exposure
-
Tan development depends heavily on weather and location
Factors That Affect Tanning Speed
Skin Type
Fair skin tans slower and burns faster than darker skin tones.
Time of Day (Sun)
Midday sun produces faster tanning but also higher burn risk.
Bed Type
-
Low-pressure beds: slower tanning
-
High-pressure beds: faster results, higher UVA intensity
Frequency
Overexposure does not speed up tanning safely and increases skin damage risk.
Which Is More Harmful?
Both methods damage the skin, but tanning beds often cause more concentrated UVA exposure in less time, which may accelerate:
-
Skin aging
-
Collagen breakdown
-
Hyperpigmentation
-
Skin cancer risk
Health authorities classify tanning beds as carcinogenic, similar to excessive sun exposure.
Is There a Safer Way to Get Color?
If your goal is appearance without UV risk:
-
Sunless tanning products provide instant color
-
Red light therapy supports skin quality without tanning or UV radiation
These options do not involve UV exposure.
Final Thoughts
When comparing tanning bed time vs sun time, the key takeaway is simple:
Tanning beds tan faster, but faster does not mean safer.
A short tanning bed session can equal hours in the sun in terms of UV exposure.
Minimizing UV exposure remains the best choice for long-term skin health.
FAQs
Is 10 minutes in a tanning bed the same as sunbathing all day?
Not all day, but it can equal several hours of strong midday sun.
Do tanning beds tan faster than the sun?
Yes. Tanning beds deliver more intense UV radiation in a shorter time.
Can you switch between sun tanning and tanning beds?
Mixing both increases cumulative UV exposure and skin damage risk.
