Protect all three parts of the body from ultraviolet rays
Living in a tropical country where the sun is almost all year has its own advantages. However, exposure to ultraviolet light can cause health problems.
There are three types of ultraviolet radiation based on short wavelengths of light and their effect on the skin. The first type, the shortest is UVC, is fully absorbed by the atmosphere and will not reach the surface of the earth. Whereas UVB is a medium-sized beam which only gives a limited effect on the surface of the skin. While UVA is the longest wave of ultraviolet light, it accounts for 95% of the ultraviolet light reaching the surface of the earth. UVA exposure can penetrate the surface layer of the skin.
Parts of the body to protect from UV rays
Because ultraviolet light can reach the surface of the skin deeper, you need to be aware of the dangers of ultraviolet radiation for health, especially in certain body parts:
Eye
The blinking eyelid reflex is the body's attempt to protect the eyes from various causes of interference, including exposure to light or bright light. Exposure to ultraviolet light in the eye can cause burning, out and vision loss.
In the long run, exposure to UV radiation can cause eye diseases, such as:
skin
Ultraviolet light damages the skin's elastin fibers and prevents facial skin tension from returning to normal. This causes sagging skin. Ultraviolet light can also penetrate deeply into the layers of the skin where blood and connective tissue are located. Premature aging is thought to be due to the fact that UVA rays increase oxidative stress in cells.
Meanwhile, UVB stimulates melanin production and thicker epidermal cell production. Therefore, UVBs actually help the body fight the damage caused by ultraviolet light. However, excessive UVB exposure can also cause sunburn which can lead to the development of cancer cells.
Here are some skin problems that can be caused by exposure to ultraviolet light:
Sunbathing and drinking enough mineral water can provide comfort and replace lost body fluids. To help you recover, you can apply a cream containing moisturizer and aloe vera to the burned skin.
Consult a dermatologist immediately if you have a burn due to excessive exposure to ultraviolet light, especially if the symptoms are accompanied by high fever, dehydration, and severe pain that lasts more than two days.
With regard to skin cancer, possible treatments include surgery, chemotherapy and radiation therapy.
Immune system
It is believed that UV light is absorbed by skin molecules which can affect the cellular response and immune system to certain diseases.
Avoid the risk of UV rays
If you frequently do outdoor activities, you cannot avoid exposure to the sun's UV rays. However, there are simple ways to minimize the effects of UV rays, including:
In Indonesia, the sun shines almost all day. To minimize the negative effects of ultraviolet light, it is recommended to limit outdoor activities in hot weather between 11: 00-15: 00. If you have certain skin conditions, you should consult a doctor for the best advice.

In the long run, exposure to UV radiation can cause eye diseases, such as:
- Photokeratitis or inflammation of the cornea, as well as visiting photitis or inflammation of the conjunctiva (layers in the eyelids and orbit). Although it can be very painful, both eye diseases can be cured and usually do not cause long-term vision problems.
- Cataracts can occur due to protein breakdown in the lens, producing a buildup of pigments which, over time, cause blindness. As we get older, cataracts can get worse due to UVB exposure. The good news, cataracts can be treated by cataract surgery and implantation of an artificial lens.
- Eye cancer. This study found that several types of eye cancer can be associated with long-term sun exposure, including one type of dangerous eye cancer, melanoma.
- Pterygium, which is a fibrovascular tissue that develops from the inner corner of the eye to the middle of the eye. This tissue growth is associated with UV exposure. Over time, this tissue can close the pupil's hole and block vision. Pterygium can be treated surgically, but it can grow back.

Here are some skin problems that can be caused by exposure to ultraviolet light:
- Sunbathing or sunburn. Basking in the sun causes deadly ultraviolet rays and damages cells on the surface of the skin. Burned skin can become red. Although it can disappear within a few days, this disease can cause blisters and peeling skin. New skin that appears after that is more susceptible to UV.
- Wrinkle skin. Those who do not protect their skin from the beginning of this ray can experience premature aging.
- Skin cancer (melanoma) and precancerous (actinic keratosis).
- Skin injury due to decreased immune function.
- Benign tumor.
- Skin color changes, resulting in freckle pigmentation.
- Skin color becomes yellow.
- Telangiectasia (dilation of small blood vessels under the skin).
- Elastosis (destruction of collagen elastic tissue). The skin easily collapses, wrinkles, and scratches.Some people's skin is more sensitive to UV. This condition is called photosensitivity, where even a small amount of UV can cause a reaction on the skin, such as a rash or severe sunburn. This condition is often associated with the use of certain drugs, such as nonsteroidal anti-inflammatory drugs, antibiotics and antidepressants.

Avoid the risk of UV rays
If you frequently do outdoor activities, you cannot avoid exposure to the sun's UV rays. However, there are simple ways to minimize the effects of UV rays, including:
- Use sunscreen with an SPF of at least 15, about 20 minutes before being exposed to ultraviolet light. Keep in mind that sunscreen performance is also influenced by sweat, humidity, wind and the right application.
- Sunscreens aged 1 to 2 years have lost their benefits, so they should no longer be used. Sunscreen must be applied again every 2 hours or when you sweat a lot. Likewise when you swim.
- After applying sunscreen on your feet and hands, don't forget to rub your neck, back of your hands, lips, and ears.
- Avoid applying sunscreen with other ingredients, such as mosquito lotions and lotions, because it cannot protect the skin.
- Contrary to popular belief, wearing dark and tight clothing is more effective at protecting skin from UV rays than loose, brightly colored clothing.
- Use a hat and sunglasses that protect the eyes from UV rays.
In Indonesia, the sun shines almost all day. To minimize the negative effects of ultraviolet light, it is recommended to limit outdoor activities in hot weather between 11: 00-15: 00. If you have certain skin conditions, you should consult a doctor for the best advice.
