In the ever-changing world of health and wellness, it can be challenging to discern what’s truly beneficial, especially during the summer months.
Products once hailed for their virtues can come under scrutiny when new research emerges.
So, how do you strike the right balance?
In this guide, we’ll delve into the science behind sunscreen and vitamin D to help you make informed decisions about their use.
Explore the sunscreen-Vitamin D debate and learn how to safely enjoy the sun. Get tips for balanced sun protection and vitamin D production.
The sunscreen-vitamin D debate
Recent studies have sparked a debate about the effectiveness of sunscreen and its potential impact on vitamin D production.
Let’s examine the facts to determine whether sun protection is a friend or foe.
Understanding study biases
Prominent dermatologist Richard Weller and researcher Pelle Lindqvist have questioned the necessity and safety of sunscreens.
However, it’s worth noting that Weller is also affiliated with Relaxsol, a company promoting sun protection that claims to allow safe tanning without hindering vitamin D production.
Sun exposure and longevity
A study conducted by Lindqvist in 2016 analyzed the sun exposure habits of 29,518 Swedish women over two decades.
The results suggested that women who frequently exposed themselves to the sun had a lower rate of heart disease.
However, the study’s methodology and key factors like protective measures during tanning were not thoroughly addressed.
Sun and blood pressure
Richard Weller’s research involving 300,000 US citizens hinted at a potential link between sunny climates and lower blood pressure.
While this study remains unvalidated and unpublished, it aligns with previous research suggesting a connection between sun exposure and better blood pressure control.
Sunscreen’s SPF rating
Ask someone who has gotten a strong sunburn despite being screened and you will understand the obvious bias of this research.
The effectiveness of sunscreen is measured in SPF (Sun Protection Factor), which is a measurement scale of UVA UVB blocking.
The higher the index, the more UVB rays are blocked.
| SFP | UVB % |
| 15 | -93 |
| 30 | -97 |
| 50 | -98 |
For best results, apply 2mg / cm2 every two hours.
But most people do not follow these recommendations and do not respect the renewal of the skin application.
Proper sunscreen application
For optimal protection, it’s essential to apply sunscreen at a rate of 2mg/cm2 every two hours.
Unfortunately, many people neglect these recommendations, leading to inadequate protection.
Misuse of sunscreen
Even with regular application, a significant amount of solar radiation reaches the skin.
Studies suggest that despite sunscreen use, sufficient vitamin D production occurs due to sunscreen imperfections and user errors.
However, UVB rays responsible for vitamin D synthesis can also contribute to skin damage and carcinogenesis.
Tips for safe sun exposure
To achieve a balance, consider these guidelines:
1 – Skin color
Individuals with lower skin pigment should use UV protection to prevent sunburn and skin cancer.
Those with darker skin should also use sunscreen to avoid epidermal disorders.
2 – Daily protection
Wear protective clothing and a hat in addition to sunscreen to minimize sunburn and tanning booth risks.
3 – Substances to avoid
Opt for sunscreens containing zinc oxide and titanium dioxide while avoiding products with oxybenzone and parabens.
