June 30th marks the end of Men's Health Month, but your health shouldn't be a once-a-year focus. As we head into the hottest months of the year, one of the most important—and often overlooked—healthy habits is protecting yourself from excessive sun and UV exposure.

Many people associate sunshine with good health, and for good reason. Spending time outdoors can improve mood, encourage physical activity, support healthy sleep by regulating your body's circadian rhythm, and stimulate the production of vitamin D (National Institutes of Health [NIH], 2022). Time outside is an important part of a healthy lifestyle—but moderation is key.

The important distinction is this: some sunlight is beneficial, but too much UV exposure can have lasting health consequences.

The Benefits of Moderate Sun Exposure

Sunlight provides several health benefits when enjoyed responsibly:

• Supports vitamin D production. UVB rays trigger vitamin D synthesis in the skin, an essential nutrient for bone health, muscle function, and immune support (NIH Office of Dietary Supplements, 2022).
• Promotes mental well-being. Natural daylight helps regulate circadian rhythms and can positively influence mood and sleep quality (National Institute of General Medical Sciences, 2023).
• Encourages physical activity. Warm weather often motivates people to walk, bike, hike, golf, garden, or participate in other outdoor activities that support cardiovascular and metabolic health.

While sunlight contributes to vitamin D production, the American Academy of Dermatology recommends obtaining vitamin D through food and supplements rather than intentional unprotected sun exposure because UV radiation is a known cause of skin cancer (American Academy of Dermatology, n.d.).

Too Much Sun Can Be Dangerous

Ultraviolet radiation damages skin cells over time. Even if a sunburn heals within days, the DNA damage caused by UV exposure can accumulate throughout life.

Excessive UV exposure increases the risk of:

• Sunburn
• Premature skin aging, including wrinkles and age spots
• Cataracts and other eye damage
• Immune system suppression
• Skin cancers, including melanoma (U.S. Environmental Protection Agency [EPA], n.d.)

According to the EPA, exposure to UV radiation is the most preventable risk factor for skin cancer (EPA, n.d.). The American Academy of Dermatology also reports that one in five Americans will develop skin cancer during their lifetime, highlighting the importance of prevention (American Academy of Dermatology, n.d.).

Why Men Should Pay Particular Attention

Men are generally less likely than women to use sunscreen regularly or seek preventive healthcare. They may also spend more time outdoors for work, recreation, or sports, increasing cumulative UV exposure.

Research shows that men—particularly older men—have higher mortality rates from melanoma than women, making prevention and early detection especially important (American Cancer Society, 2025).

Smart Sun Habits This Summer

You don't have to avoid the outdoors to protect yourself. Instead, practice smart sun safety:

• Use a broad-spectrum sunscreen with SPF 30 or higher every day you expect prolonged outdoor exposure.
• Reapply sunscreen every two hours and after swimming or heavy sweating.
• Wear protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
• Seek shade whenever possible, especially between 10 a.m. and 4 p.m., when UV rays are strongest (Centers for Disease Control and Prevention [CDC], 2024).
• Check your local UV Index before spending extended time outdoors.
• Remember that water, sand, pavement, and snow can reflect UV rays, increasing exposure.
• Don't rely on cloudy skies for protection—up to 80% of UV rays can penetrate clouds (EPA, n.d.).

The Bottom Line

Men's Health Month may be over, but protecting your health continues every day. Summer offers countless opportunities to enjoy the outdoors, stay active, and spend time with family and friends. By taking simple precautions against excessive UV exposure, you can enjoy the benefits of sunshine while reducing your risk of skin cancer, premature aging, and other sun-related health problems.

This summer, make sunscreen, protective clothing, and shade part of your daily routine. Your skin—and your future self—will thank you.
