The Hidden UV Trap: Why Glass Doesn't Protect Padel Players

Yes, you absolutely need sunscreen for padel. UV radiation reaches your skin throughout every match, regardless of court type. A typical padel session of 60 to 90 minutes is more than enough time to cause measurable skin damage (Skin Cancer Foundation, 2025).

Padel is one of the fastest growing racquet sports in the world, with an estimated 35 million players globally as of 2025. Yet most players step onto the court without applying sunscreen. According to dermatologists, this puts them at unnecessary risk for sunburn, premature aging, and skin cancer.

Why Padel Courts Are a UV Trap

Padel courts create a unique UV environment that most players underestimate. The enclosed design, with tempered glass back walls and metallic mesh side panels, actually intensifies UV exposure rather than blocking it.

Glass Transmits UVA

Standard padel courts use 10 to 12 mm tempered glass panels for back walls and partial side walls (Portico Sport, 2024). While glass blocks most UVB rays (the ones that cause sunburn), it transmits a significant portion of UVA radiation. UVA penetrates deeper into the skin and is the primary driver of premature aging and melanoma risk (Skin Cancer Foundation).

Glass walls are for ball containment, not sun protection. Treat every padel session as full sun exposure.

Reflective Surfaces Hit You from Every Angle

Court surfaces, glass walls, and surrounding concrete all reflect UV rays back toward players. The Skin Cancer Foundation notes that reflective surfaces can bounce back up to 80% of UV rays (Skin Cancer Foundation, 2025). While court surfaces reflect less than snow, the enclosed nature of a padel court means UV hits you from above, below, and both sides simultaneously.

Match Duration Pushes the Limit

A typical match lasts 60 to 90 minutes, and tournament play can keep you on court for several hours (All for Padel). The American Academy of Dermatology recommends reapplying sunscreen every two hours. Even a single match pushes you close to that threshold (AAD).

What Dermatologists Actually Recommend

Skin cancer is the most common cancer worldwide, and UV radiation is its primary cause. The World Health Organization classifies UV radiation as a proven human carcinogen and notes that outdoor athletes face increased risk (WHO, 2022).

Dr. Henry W. Lim, MD, FAAD, former president of the American Academy of Dermatology, has stated: "To reduce the risk of skin cancer, dermatologists recommend generously applying a water resistant, broad spectrum sunscreen that protects against both types of ultraviolet radiation (UVA and UVB) with an SPF 30 or higher" (Practical Dermatology).

For padel specifically, dermatologists recommend:

• Broad spectrum SPF 30 or higher to protect against both UVA and UVB

• Reapply every two hours, or sooner if sweating heavily (Skin Cancer Foundation)

• Cover commonly missed areas: ears, back of neck, tops of hands, and lips (BloqUV, 2025)

• Apply 15 minutes before stepping on court so the sunscreen has time to bind to skin

The Athlete Sunscreen Gap

Despite knowing the risks, outdoor athletes consistently under protect themselves. A 2023 narrative review in the journal Cancers found that sunburn rates among outdoor athletes reached 45.6%, and many athletes "almost never" use sunscreen during training or competition (Borkowski et al., 2023, PMC). Sweating compounds the problem by increasing skin photosensitivity and washing away applied sunscreen.

The Long Term Cost of Skipping Sunscreen on Court

Sunburn fades in a few days, but UV damage is cumulative. Every unprotected padel session adds to a running total that your skin does not forget.

Photoaging Hits Athletes Earlier

Dermatologists use the term "photoaging" to describe skin damage caused specifically by UV exposure rather than normal aging. The visible signs include wrinkles, dark spots, uneven texture, and loss of elasticity. A landmark study published in Clinical, Cosmetic and Investigational Dermatology found that chronic UV exposure is responsible for up to 80% of visible facial aging (Flament et al., 2013). For outdoor athletes who train multiple times per week, this accumulation happens faster than it does for people with mostly indoor lifestyles.

Padel players are particularly affected because the sport demands year round outdoor play in many regions. A player who trains three times per week for 90 minutes without sunscreen accumulates roughly 234 hours of unprotected UV exposure per year. Over five years, that is more than 1,100 hours of direct and reflected UV hitting exposed skin.

Skin Cancer Risk Is Real, Not Theoretical

The Skin Cancer Foundation reports that one in five Americans will develop skin cancer by age 70 (Skin Cancer Foundation, 2025). Having five or more sunburns doubles the risk of melanoma, the most dangerous form of skin cancer. For outdoor athletes who experience repeated low level burns (the kind that turn pink but not red), the risk builds silently over years.

Regular sunscreen use reduces melanoma risk by 50%, according to a study published in the Journal of Clinical Oncology (Green et al., 2011). That single statistic makes sunscreen one of the most effective health interventions available to any athlete.

The Compound Effect of Consistent Protection

The good news is that consistent sunscreen use does not just prevent future damage. Research shows it can also allow existing damage to partially repair. A 2013 study in Annals of Internal Medicine found that daily sunscreen users showed 24% less skin aging than intermittent users over a four year period (Hughes et al., 2013). This means that starting a consistent sunscreen habit today, even if you have been playing without protection for years, still delivers measurable benefits.

For padel players, the math is simple: protect your skin during every session, and you preserve both your health and your appearance over thousands of hours of court time.

How to Pick a Sunscreen for Padel

When selecting a sunscreen for court sports, these four factors matter most:

1. SPF 50 broad spectrum: Higher protection gives you more margin during extended play. The AAD recommends SPF 30 as a minimum; SPF 50 is ideal for prolonged outdoor activity (AAD).

2. No white cast, no grip interference: You need clean hands and a firm grip on your padel racket. Heavy, greasy sunscreens make handles slippery and leave residue on glass walls.

3. Portable stick format: Changeovers during padel are short. A sunscreen you can apply with one hand, without washing up, is essential for consistent reapplication.

4. Skin nourishing ingredients: Extended sun exposure and sweat dehydrate skin. Ingredients like ceramides help maintain the skin barrier during and after play.

HAESKN SPF 50 Sunscreen Stick is designed with these court conditions in mind. It is FDA approved, broad spectrum SPF 50 with a transparent finish on all skin tones. The stick format allows mess free reapplication during changeovers, and ceramides, ginseng, and rice extracts support skin throughout long sessions. At $28, it sits between budget drugstore options and premium dermatologist brands.

Common Sunscreen Mistakes Padel Players Make

Even players who do wear sunscreen often make errors that reduce protection significantly. Here are the most common ones and how to fix them.

Applying on Court Instead of Before

Many players wait until they arrive at the court to apply sunscreen. By then, warmups have already started. Sunscreen needs at least 15 minutes to bind to your skin and form a stable protective layer. Applying in the car, at the locker room, or at home before leaving gives you the full benefit of your SPF rating.

Using Too Little Product

The AAD's recommended amount of one ounce for full body coverage sounds like a lot, and it is. Most people apply about half of what they should, which reduces SPF protection by roughly 50%. If you are using a stick sunscreen, the instinct is to do one quick swipe. That is almost never enough. Three to four full passes per area is the minimum for adequate coverage.

Skipping the Ears, Neck, and Hands

The face gets the most attention, but padel players frequently burn on the tops of their ears, the back of the neck, and the backs of their hands. These areas receive direct and reflected UV for the entire match. Hands are especially vulnerable because they are constantly exposed and rarely covered by clothing.

Relying on "Morning Application" for Afternoon Matches

Sunscreen applied at 8 AM does not protect you at 2 PM. The active ingredients break down under UV exposure, and sweat accelerates the process. Every session needs fresh application, regardless of what you put on earlier in the day.

Choosing Lotion Over Stick for Court Sports

Lotion sunscreens work well at the beach, but they create problems on the padel court. Greasy hands affect your grip. Lotion takes longer to absorb. And reapplication during changeovers is messy and slow. A stick format solves all three issues: it applies dry, leaves no residue, and takes seconds to use with one hand.

A Padel Player's Sunscreen Routine

Before Your Match (15 to 30 Minutes Prior)

Apply sunscreen at least 15 minutes before heading to the court. This gives active ingredients time to bind to your skin and form a protective barrier.

Amount matters. The AAD recommends about 1 ounce (a shot glass full) for your entire body. For face and exposed areas during padel:

• Face and neck: nickel sized amount (or 3 to 4 full swipes with a stick sunscreen)

• Each arm: half a teaspoon

• Back of neck and ears: dime sized amount

Most people apply only 25 to 50% of the recommended amount, which can cut SPF protection in half. With a stick sunscreen like HAESKN, make 3 to 4 full passes over each area to ensure adequate coverage.

During Your Match (Every 60 to 80 Minutes)

Plan to reapply between sets or during water breaks. In tournament play with back to back matches, reapply immediately after finishing one match and before starting the next.

Stick sunscreens are ideal for courtside reapplication. No hand washing required, no residue on your racket grip or the glass walls.

High priority reapplication zones:

• Forehead and nose (highest sun exposure)

• Tops of ears

• Back of neck

• Forearms and backs of hands

After Your Match

If you are still spending time outdoors after playing (watching other matches, socializing at the club), reapply. UV damage accumulates throughout the day, not just during active play.

Beyond Sunscreen: Complete Court Sun Protection

Sunscreen is the first line of defense, but dermatologists recommend layering protection:

• Sunglasses with UV protection: Shield your eyes from reflected glare off glass walls and court surfaces

• Hat or visor: Protect your face and scalp during outdoor play

• UV protective clothing: Long sleeve performance shirts with UPF ratings are increasingly popular among padel players (BloqUV, 2025)

• Schedule smart: When possible, book courts for early morning or late afternoon to avoid peak UV hours (10 AM to 4 PM)

• Lip balm with SPF: One of the most commonly forgotten areas of sun protection

Frequently Asked Questions

Do I need sunscreen if I play padel indoors?

If the facility is fully enclosed with a solid roof and artificial lighting, UV exposure is minimal. However, many "indoor" padel facilities use translucent roofing or open sides that still allow UV penetration. When in doubt, apply sunscreen.

How often should I reapply sunscreen during padel?

The Skin Cancer Foundation recommends reapplying every two hours, or immediately after heavy sweating (Skin Cancer Foundation). For a typical 90 minute match, apply before the match and reapply at changeovers if you are sweating heavily.

Does the glass on padel courts block UV rays?

Partially. Tempered glass blocks most UVB rays but transmits a significant amount of UVA radiation, which causes deep skin damage and increases skin cancer risk (Skin Cancer Foundation). Glass walls should not be relied upon for sun protection.

What SPF should I use for padel?

Dermatologists recommend a minimum of SPF 30 broad spectrum for any outdoor activity. SPF 50 is preferable for extended exposure like padel matches and tournaments (AAD).

Can I get sunburned on a cloudy day while playing padel?

Yes. Up to 80% of UV rays can penetrate cloud cover (WHO, 2022). Cloud cover reduces the sensation of heat but not the UV damage to your skin. Always apply sunscreen regardless of weather conditions.
