I love the sun, it keeps me warm and makes me smile. I long for beautiful sunny days to be outdoors enjoying nature. As South Africans we are blessed to live in one of the top 10 sunniest countries in the world according to the U.N
There are many benefits to the sun, the first of which is how it keeps us happy. A study recently published in the UK showed spending an extra hour in the sun daily leads to lower levels of depression and a longer lifespan. The reason for this lies in the hormone called serotonin, otherwise known as the happiness hormone. Sunshine helps our bodies create more serotonin, making us feel happier.
The sun also keeps illness away. When we are exposed to the sun the body starts producing vitamin D. Vitamin D is essential for reducing the risk of certain diseases and keeping our bones, muscles and teeth healthy.
It is important for us to get a good deal of sun but we also need to be aware of the dangers of how it can affect our skin.
HOW THE SUN DAMAGES OUR SKIN
The outer layer of our skin contains collagen and elastin which keeps the skin smooth and tight. When our skin is exposed to ultraviolet (UV) rays from the sun the collagen and elastin is broken down which in turn leads to fine lines, wrinkles and pigmentation.
Let’s dive deeper into how this works:
The sun emits three types of rays, UVA, UVB and UVC. UVC is the most dangerous but thankfully these are mostly blocked by the earth’s ozone layer. Both UVA and UVB rays can cause a lot of damage to our skin and we need protection from both.These rays penetrate deep into the outer and middle dermal layers of the skin. Ongoing exposure to the sun’s radiation causes the breakdown of collagen fibers which in turn increases elastin production. This imbalance leads to the sagging and wrinkling of the skin.
One of the most common effects of the sun is freckles and sun spots. We have pigment cells in our skin that become damaged when exposed to sunshine and cause blemishes to become larger.
And finally the sun can cause skin cancer. Skin cancer is caused by the UV radiation from the sun breaking down the DNA in our skin. DNA is responsible for controlling how our cells function, if these cells are damaged, over time they can begin to grow uncontrollably which leads to skin cancer.
There are three main types of skin cancer, melanoma, basal cell carcinoma and squamous cell carcinoma. Melanoma is the most deadly as it can spread rapidly throughout the body while the other two tend to spread locally. Melanoma is primarily caused by exposure to the sun while the others can be caused by other factors such as skin type.
PROTECTING OUR SKIN
These simple steps can help us enjoy the sun while protecting ourselves from the damages the sun can cause:- Apply Sunscreen - more regularly than you think you need
- Protect your head
- Choose your sun-time wisely
- Block, block, block
- Rebuild your collagen
- Invest in the right sun stoppers
These small daily routines can have a huge impact on our health and wellbeing.
We can also teach our children the same lessons and get them into the routine of applying their suncreen and putting a hat on before they start their day.
GET OUTSIDE & ENJOY THE SUN
We don't need to fear the sun. After all, it is the giver of all life on Earth. However, it should always be respected. Enjoy being outside while also taking the necessary precautions to take care of our skin. Believe me, your older self will thank your younger self.
