Is sunscreen the new margarine? (2019)

a month ago

Vitamin D supplementation has failed in clinical trials despite initial high hopes for its benefits against various diseases.
Sunlight exposure triggers beneficial compounds like nitric oxide, which can lower blood pressure and reduce cardiovascular risks.
Avoiding sun exposure may increase overall mortality risk, with some studies comparing it to smoking in terms of life expectancy impact.
Skin cancer risks are often overstated; most skin cancers are non-fatal, and melanoma rates are lower in regular sun-exposed individuals.
Current sunscreen guidelines may not account for skin color differences, with darker-skinned people having lower melanoma risk but potential vitamin D deficiencies.
Historical parallels exist, such as the margarine and trans fat debacle, suggesting current sun-avoidance advice could be similarly flawed.
Some countries, like Australia, have updated guidelines to balance sun exposure for vitamin D production while minimizing skin cancer risks.
Experts recommend a sensible approach to sun exposure, avoiding burns and using protective clothing rather than relying solely on sunscreen.
