The query revolves around the reasons for not using sunscreen and the contrasts involved in this practice.
In the sunny months, it's essential to strike a balance between enjoying the outdoors and protecting our skin. Here's a rundown of the key facts to help you make informed decisions.
Sunscreen does not hinder the body's absorption of Vitamin D under normal circumstances. However, to fill the Vitamin D stores, only about half the time in the sun before a sunburn would occur is necessary, as suggested by Breitbart.
While the sun does not cure conditions like neurodermatitis and asthma, it can help reduce itching in eczema and neurodermatitis. However, it's important to note that UV rays do not distinguish between normal and inflamed cells, posing a risk of skin cancer decades later.
Dermatologist Fabian Kowallik recommends a balanced approach to the sun, including up to 10-30 minutes of midday sun and utilizing sun time outdoors. He also advises checking the UV index for the day, wearing clothing that blocks light, and applying sunscreen with an SPF of 30 that protects against both UVB and UVA. Avoiding midday sun and scheduling activities in the morning and afternoon is also recommended.
However, even with sunscreen, it's crucial not to expose oneself to the sun for too long. Proper sun protection includes wearing protective clothing, checking the UV index, applying sunscreen, and avoiding midday sun.
Coconut oil does not provide strong sun protection. A 2022 overview study found that coconut oil alone has a sun protection factor of only 7. Therefore, it's not a reliable sunscreen alternative.
Experts recommend using sunscreens with a sun protection factor of 30 or 50 when sunbathing. Zinc oxide, a common mineral filter in sunscreens, carries risks when mixed by consumers, with the Federal Institute for Risk Assessment considering concentrations of up to 25 percent of nano-zinc oxide safe.
There are concerns about mixing zinc oxide and coconut oil for sunscreen, as experts question the correct mixing ratio, shelf life, and toxicological data.
It's also worth noting that a 2021 Öko-Test study found benzophenone, a breakdown product of octocrylene and benzophenone-3, in several sunscreens. Both the International Agency for Research on Cancer and the European Chemicals Agency classify benzophenone as "possibly carcinogenic," based on animal studies but limited human evidence. Since December 2023, benzophenone is banned in EU cosmetic products due to this classification.
In conclusion, a balanced approach to sun exposure and sunscreen use is key to enjoying the summer months safely. Always remember to check the UV index, wear protective clothing, apply sunscreen with an SPF of 30 or higher, and avoid midday sun to minimise the risks associated with sun exposure.
