Sun exposure has been shrouded in a lot of myths that can heavily affect your day-to-day health choices. While sunlight is essential for vitamin D production, myths surrounding them often result in too much/too little exposure. Knowing these myths are critical for making smart sun safety and health related decisions.
Check out a few below and how to navigate them.
Myth 1: Sunscreen Blocks all Vitamin D Production.
A common myth is that sunscreen use completely blocks the body’s ability to produce vitamin D. In reality, although sunscreen reduces the amount of UV radiation reaching the skin, it doesn’t completely prevent vitamin D synthesis. Studies show that even with sunscreen, sufficient vitamin D levels can be maintained through regular outdoor activities and a balanced diet.
Myth 2: Tanning Beds are Safer Than Sunlight.
Some think tanning beds provide a safer option than natural sunlight since they control UV exposure. However, tanning beds deliver concentrated UVA and UVB rays, increasing the risk of skin cancer and premature aging more than natural sunlight. The WHO classifies tanning beds as carcinogenic, highlighting their potential danger.
Myth 3: Dark Skin Does Not Need Sun Protection.
Many believe that people with darker skin tones don’t need sun protection, courtesy of more melanin. While melanin provides some level of protection from UV, it doesn’t completely rule out the risk of skin damage or cancer. No matter what your skin tone, everyone should apply sunscreen with at least SPF of 30 when staying in sunlight for long.
Myth 4: Cloudy Days Mean No Sunburn Risk.
Many think that cloudy days remove the risk of sunburn, as they block direct sunlight. But did you know that up to 80% of UV rays can penetrate clouds and damage your skin, without you realising until later in the day? Apply sunscreen even in overcast days to protect from unexpected UV exposure.
Myth 5: Base Tan Prevents Future Burns.
The notion that getting a base tan prevents future burns is a myth. A base tan only offers minimal protection equal to an SPF 3 or less, which is not enough to prevent burns from extended sun exposure. Using a base tan in place of proper sun protection raises the risk of cumulative skin damage or over time.
