The days are short and there's little sunshine breaking through the thick layer of winter cloud. You ask yourself, do I really need sunscreen on todays hike/run/swim/surf/climb etc... ?
We don't get burnt as often in winter, why?
The UVB rays, which carry the most energy are the chief cause of skin reddening and sunburn, and tend to damage the skin's more superficial epidermal layers. They play a key role in the development of skin cancer and a contributory role in tanning and photoaging.
The intensity of UVB rays varies by season, location, and time of day and is weakest in winter, which is why we feel we can escape being sunburnt 💪🏻🔥 !
However, in high altitudes and on reflective surfaces such as snow or ice, which bounce back up to 80 percent of the rays, UVB rays can still be damaging even in winter.
So there are less UVB rays in winter. That is, if you're not enjoying an epic snow season, in which case you better Butter Up!
But not so fast. The valley and coastal people still need to be aware of UVA rays. The UVA penetrates the skin more deeply than UVB, and has long been known to play a major part in skin ageing and wrinkling (photoaging). Studies over the past two decades, show that UVA also damages skin cells called keratinocytes in the basal layer of the epidermis, where most skin cancers occur. It is now believed UVA contributes to and may even initiate the development of skin cancers (skincancer.org).
Having a winter suncare routine is important through the cold months to protect your skin from UVA rays, or both UVA/UVB rays in the snow and high altitudes, and will help reduce premature skin ageing and long-term skin damage ❄️💙🤟🏼
:: Wear SunButter sunscreen when spending time outdoors, or our long lasting surf zincs when doing water sports
:: Don’t put the hats away in the summer box unleash them ! Or don a peaked beanie for walks and hikes
:: Wear gloves to reduce sun exposure to your hands, especially when driving
:: Make sure to get a little bit of unblocked sunshine amongst it all too 🌻 ☀️ 🌻
Sunshine is very beneficial, it keeps your bones healthy! How? Your body produces vitamin D when exposed to the sun, which helps the body absorb calcium essential for bone health.
So remember, all in moderation. Think SunSmart when you're outdoors for hours, but also take some time to nourish your body with a little sunshine appetiser to keep body, mind and soul together.
Thanks for tuning in! Spread the love, #spreadthebutter
