While Vitamin D from the tropical sun is good for the health, Dr. Kwan Yuan Dong from S Aesthetics Clinic shares more on why using sunscreen is important if you are spending long hours out in direct sunlight.

[1] reduces your risk of skin cancer

Said Dr. Kwan, “On TV, in advertising, and from doctors, we have heard that UV rays age our skin and can cause skin cancers. Yet some of us find that putting on sunscreen is too much of a hassle.”

“But there is a direct association between lifetime sun and a variety of skin cancers. Using sunscreen decreases your risk of developing these cancers by between 40 to 50 per cent.”

[2] keeps you youthful 

As well, Dr. Kwan adds that ultraviolet (UV) exposure is directly linked to premature ageing. By using sunscreen, you can slow down this ageing process and delay the development of wrinkles and leathery skin.

[3] keeps your skin tone even

Said Dr. Kwan, “sunscreen also prevents the development of brown spots and skin discolouration.”

[4] depleting ozone layer

With the depletion of the ozone layer, we need additional protection from the harmful UV-B rays before they reach the ground. The function of the ozone layer is to absorb these UV-B rays before they hit the surface of the Earth.

[5] Sun damage take place over time

While you will get a sunburn if you are out in the sun for a prolonged period, Dr. Kwan adds that everyone is susceptible to skin cancer, even if your skin does not burn easily. ‘

He said, “Sunburn is only an immediate reaction of your skin to UV exposure but sun damage is accumulated over a lifetime. Skin cancer does not discriminate against any skin type as long as sun exposure builds up over time over unprotected skin.”

[6] Apply and reapply

Dr. Kwan adds that when you apply sunblock, it needs to be reapplied every two hours to keep up the SPF protection against the sun, otherwise it will wear off and you will no longer be protected. As well, he reiterates that you also need to reapply regularly every time you get out of the water or do water sports as water washes off sunblock.

[7] Protects you from heatstroke and heat exhaustion 

Sunblock, according to Dr. Kwan, can also give you some protection from heat-stroke and heat exhaustion. He adds, “Putting on sunscreen protects you to a certain extent and when in combination with precautions such as hydration, which can help you avoid these issues.”

[8] Set a good example

Said Dr. Kwan, “By setting a good example for our kids, we can ensure that they grow up understanding the importance of UV protection and avoid running into problems later in life.”

Conclusion 

In conclusion, Dr. Kwan adds that it is never too late to start integrating sun-safe habits into your life. He explained “By wearing sunscreen, you can help protect yourself from the harmful effects of UV rays.”
