What Is 15 Minutes on a Tanning Bed Equivalent To In The Sun?

What is 15 minutes on a tanning bed equivalent to in the sun

Have you ever wondered how long a 15-minute tanning bed session compares to basking under the sun? Here’s an intriguing fact: it’s roughly akin to spending about 2-3 hours in direct sunlight.

In this illuminating article, we’ll shed light on what drives this startling comparison and help you understand the impact of UV exposure from both sources.

Key Takeaways

  • Spending 15 minutes in a tanning bed is roughly equivalent to spending 2 – 3 hours in direct sunlight.
  • Different types of tanning beds vary in power and effect, with high-pressure versions delivering intense UV radiation equivalent to 2-4 minutes of sun exposure within just one minute.
  • Tanning beds emit both UVA and UVB rays, with higher levels of UVA radiation compared to natural sunlight.

Often underplayed is the intensity of UV exposure in tanning beds. Many believe that these machines provide a safer alternative to natural sunlight; however, this couldn’t be further from the truth.

A mere 15 minutes spent inside a tanning bed equates to about 2-3 hours basking under direct sunlight without protection – no small amount! This comparison holds whether you’re lounging on a beach or catching rays in your backyard.

The artificial tan achieved through sunbed use doesn’t quite mirror the effects of actual sunbathing.

High-pressure versions deliver intense UV radiation equivalent to 2-4 minutes of sun exposure within just one minute! Meanwhile, their low-pressure counterparts offer an exchange rate closer to 2-20 minutes of natural sunshine per minute spent underneath those glowing bulbs.

These differences underscore that comparing duration time between sunbeds and real suntans isn’t a straightforward task but rather depends heavily on equipment type and individual skin response.

Understanding the UV Rays in Tanning Beds

Tanning beds are designed to emit ultraviolet (UV) rays, which are responsible for the darkening of the skin. UV rays can be divided into two types: UVA and UVB. UVA rays penetrate deep into the skin, causing long-term damage like premature aging and wrinkles.

On the other hand, UVB rays primarily affect the surface of the skin and are responsible for sunburns.

When you step into a tanning bed, you expose your skin to both UVA and UVB rays in varying intensities depending on the type of bed. It’s important to note that, unlike natural sunlight, tanning beds often emit higher levels of UVA radiation.

This is why it is crucial to understand that using a tanning bed does not provide an equivalent substitute for getting natural sunlight.

Spending just 10 minutes in a tanning bed can be equivalent to about 2 hours of direct sun exposure outside. This means that even short sessions under artificial UV light can have significant effects on your skin.

It’s essential to take proper precautions such as wearing protective eyewear and limiting your overall exposure time in order to minimize potential risks associated with using tanning beds.

How Long Should I Spend In a Tanning Bed?

How Long Should I Spend In a Tanning Bed

The duration one should spend in a tanning bed largely depends on the individual’s skin type. Here are some general guidelines:

Fair skin, burns easily, rarely tans: People with this skin type are generally advised not to use tanning beds as they are at a high risk of burning and long-term skin damage.

Fair to light skin, burns easily, tans minimally: Start with short exposure times of 4-6 minutes, increasing gradually if the skin tolerates it well.

Light to medium skin, sometimes burns, tans gradually to light brown: Initial sessions could be around 6-8 minutes, slowly increasing based on tolerance.

Medium skin, burns minimally, usually tans to moderate brown: Start with sessions of about 8-10 minutes, increasing gradually.

Medium to dark skin, rarely burns, tans well: This skin type can typically start with sessions of 10-12 minutes.

However, these are just guidelines and individual reactions to UV exposure can vary. It’s crucial to always start with shorter sessions to see how your skin reacts and never to stay in a tanning bed for longer than recommended by the manufacturer.


In conclusion, comparing the UV exposure from a tanning bed to that of the sun isn’t straightforward due to various factors including the type of tanning bed, the intensity of the UV rays, and individual skin types. 

Generally speaking, 15 minutes spent on a tanning bed could be equivalent to roughly 2-3 hours under the sun, as tanning beds can emit UV rays that are much more intense than the sun’s. 

It’s crucial to remember that both tanning beds and sun exposure carry risks, including skin damage, premature aging, and an increased risk of skin risks. 


Is 15 minutes in a tanning bed the same as spending 15 minutes in the sun?

No, 15 minutes in a tanning bed is not equivalent to spending the same amount of time in direct sunlight. 

Tanning beds emit concentrated levels of UVA and UVB rays that can be stronger than natural sunlight. Therefore, 15 minutes in a tanning bed is closer to around 2-3 hours in the sun.

Is a tanning bed more harmful than sunlight?

Both tanning beds and sunlight expose the skin to harmful ultraviolet (UV) radiation, but tanning beds are often considered more harmful. This is because they primarily emit UVA radiation, which penetrates deeper into the skin causing long-term damage.
