2.
When you should apply sun screen?
Correct Answer
D. All of the above
Explanation
Applying sunscreen every 2 hours is important because sunscreen can wear off over time due to sweating, wiping with a towel, or other activities. Sweating can also dilute the sunscreen, reducing its effectiveness. Towel drying can remove the sunscreen from the skin, leaving it exposed to the sun's harmful rays. Therefore, to ensure maximum protection against sunburn and skin damage, it is recommended to apply sunscreen every 2 hours, after sweating, and after towel drying.
3.
How long does a bottle of sun screen usually work?
Correct Answer
A. 1 year
Explanation
Sunscreen typically has an expiration date of one year. This is because the active ingredients in sunscreen can degrade over time, reducing its effectiveness in protecting the skin from harmful UV rays. Using expired sunscreen may not provide the desired level of protection and could potentially lead to sunburn or other skin damage. It is important to check the expiration date on sunscreen bottles and replace them as needed to ensure proper sun protection.
4.
What are the most common sunscreen mistakes people make?
Correct Answer
A. Choosing SPF below 30
Explanation
Choosing an SPF below 30 is a common sunscreen mistake because SPF 30 or higher is recommended for adequate protection against harmful UV rays. Lower SPF levels may not provide sufficient protection, especially for prolonged sun exposure.
5.
Which of these clothing choices offers the best protection and comfort from UV rays?
Correct Answer
D. Long pants and full sleeves shirts
Explanation
Long pants and full sleeves shirts offer the best protection and comfort from UV rays because they cover more skin, reducing the exposure to harmful rays. The fabric of these clothing choices also provides a physical barrier between the skin and the sun, further minimizing the risk of sunburn and skin damage. Wearing long pants and full sleeves shirts is recommended by dermatologists and experts in sun protection to prevent sunburn and reduce the risk of skin cancer caused by UV radiation.
6.
Most dangerous UV rays are?
Correct Answer
C. UV C
Explanation
UV C rays are the most dangerous among all UV rays. UV C rays have the shortest wavelength and highest energy, making them the most harmful to human health. However, it is important to note that UV C rays are mostly absorbed by the Earth's atmosphere and do not reach the surface. UV A and UV B rays are also dangerous and can cause skin damage and increase the risk of skin cancer, but they have slightly longer wavelengths and lower energy compared to UV C rays.
7.
What does SPF stand for?
Correct Answer
B. Sun Protection Factor
Explanation
SPF stands for Sun Protection Factor. It is a measure of how well a sunscreen protects the skin from the harmful effects of the sun's ultraviolet (UV) rays. The higher the SPF number, the greater the level of protection it provides against UVB rays, which are the main cause of sunburn and skin cancer. SPF is an important factor to consider when choosing a sunscreen to ensure adequate protection from the sun's damaging rays.
8.
How much sunscreen to apply?
Correct Answer
C. Two fingers of sunscreen
Explanation
The correct answer is "two fingers of sunscreen" because this amount is generally recommended by dermatologists for adequate sun protection. Applying two fingers of sunscreen ensures that an adequate amount of product is applied to cover all exposed areas of the skin. It is important to apply enough sunscreen to achieve the desired level of SPF and to reapply every two hours or after swimming or sweating to maintain effectiveness.
9.
What are the peak hours for UV exposure?
Correct Answer
B. 10:00am – 4:00pm
Explanation
The peak hours for UV exposure are from 10:00am to 4:00pm. During this time, the sun is at its highest point in the sky, resulting in more direct and intense UV radiation. It is important to take precautions such as wearing sunscreen, protective clothing, and seeking shade during these hours to minimize the risk of sunburn and skin damage.
10.
Which of the following will protect you from UV exposure?
Correct Answer
E. All the above
Explanation
Long pants, a wide-brimmed hat, applying sunscreen, and wearing sunglasses can all protect you from UV exposure. Long pants provide coverage for your legs, reducing direct exposure to the sun. A wide-brimmed hat shades your face, neck, and ears, protecting them from direct sunlight. Applying sunscreen creates a protective barrier on your skin, blocking harmful UV rays. Sunglasses with UV protection shield your eyes from UV radiation. By utilizing all of these measures, you can effectively minimize your UV exposure.
