Reassessing Our Fear of Sun Exposure

Since the 1980s, there’s been a growing aversion to sun exposure. Dermatologists warn that healthy tanning is a myth, while influencers and celebrities tell us to use high SPF products every time we step outside. Organizations like the CDC now consider sunscreen as essential as seatbelts and flu shots.

But is this deep-seated fear truly justified?

Dr. Paul Saladino, a double board certified MD and host of the Fundamental Health podcast, has a different perspective. He believes we should actually be more critical of the sunscreens we apply. In a recent episode of “Back to the People,” Dr. Saladino discussed this view.

While sunscreen proponents often highlight cancer risks associated with sun exposure, Dr. Saladino points out that many mainstream sunscreens contain harmful substances. Ingredients like benzene, oxybenzone, octocrylene, and avobenzone are known carcinogens and endocrine disruptors.

Moreover, he argues that shunning the sun doesn’t align with our evolutionary, historical, or anthropological development. He notes that most creatures instinctively know when they’ve had too much sun exposure, something that seems to be part of life on Earth.

“Without sunlight, you can’t naturally produce vitamin D, and melatonin production also decreases,” adds Nicole, who hosts the same show.

Dr. Saladino concurs, mentioning that while it’s possible to supplement these nutrients, they’re not necessarily equivalent to natural sunlight exposure. Sunlight is also vital for regulating our circadian rhythm—the internal clock that manages our sleep-wake cycles, hormonal balance, and body temperature.

Arguably, the most crucial aspect is the psychological benefit sunlight provides. Sun exposure can help stave off depression, as it stimulates endorphins—chemicals that make us feel good. Dr. Saladino believes there’s an innate mechanism that encourages humans to seek out moderate sun exposure.

Additionally, sunlight aids in producing nitric oxide in the skin, which helps dilate blood vessels and lower blood pressure. Dr. Saladino mentions ongoing studies that suggest cardiovascular benefits from sun exposure.

Despite the mounting evidence highlighting sunlight’s importance, the medical community still seems to vilify it, suggesting we need to shield ourselves from potential toxins found in sunscreens that block sun exposure.

So, what can we do? How do we harness the benefits of sunlight while minimizing the risks of overexposure?

Dr. Saladino offers several tips:

• If you feel the need for protection, consider covering up or opting for mineral sunscreens, preferably those with non-nano zinc oxide. These types work on the skin’s surface, blocking UV rays without being absorbed.
• As for how much sun exposure is safe, it varies based on individual factors like skin tone, geography, and season. He recommends a free app called D-Minder, which helps calculate the optimal sun exposure for vitamin D production while reducing the risk of burns.
• For those with fair skin, morning sunlight is advisable since UV rays are less intense at that time.
• Finally, trust your instincts. “Many of us have an inherent sense of when we need sunlight,” he observes. So, if the sun invites you outside, your body might just be asking for it.
