Effective ways to block UV rays.


     Many people think that it is necessary to avoid ultraviolet rays (or UV rays) outdoors, but in reality, even indoors, your body is still at risk of UV damage by sunlight reflecting through windows. Windows are just as harmful to skin and eyes as outdoor UV rays. Don’t worry, here are some simple ways to protect yourself against UV rays indoors.

* Ways to avoid UV rays from outside.

1. Stick a protective film on the window.

Some types of glasses can block short-wavelength UVB rays, but with long-wavelength UVA rays, they only block 50% or less while this is the most common cause of darkening and skin cancer. At this point, one of the simplest ways to block UV rays is to add a protective film to the window. Note, do the same with all windows that get sunlight in, including car windows! The protective film can block 99.9% of UV rays.

2. Adjust your sitting position relative to the windows.

Those who often sit for a long time near an open window or do not have a protective layer of UV protection, their facial skin is very susceptible to aging. If you prefer to leave the windows open, choose a seat further away or change your seat from time to time as the sun shines through the window in different positions.

3. Use sunscreen when you are in a sunny area of the house.

This is not superfluous if you know that exposure to the sun from indoors is just as harmful as it is outdoors. Note that always use a sunscreen with an SPF of 15 or higher. A cream with a high SPF will better block both types of harmful UV rays. Alternatively, you can also use a moisturizer with UV protection, as long as it has a high or low SPF of 15.

* Ways to limit artificial sources of UV rays.

1. Apply sunscreen to your hands when going for a manicure.

You may not expect it, but in fact, the bulbs used at nail salons to dry your nails use UV rays. Although the amount of radiation and the risk of harm is low, to be on the safe side, you should apply sunscreen with an SPF of at least 15 on the back of your hands before getting your nails done.

2. Don’t sit too close to the fluorescent light.

Fluorescent light bulbs, commonly used in homes, emit small amounts of UV radiation. Although this radiation poses no significant risk, it is important not to be near the bulb (less than 30cm) for more than an hour to avoid any harm.

3. Use protective equipment when doing work exposed to UV rays.

Certain industrial and commercial occupations require workers to be exposed to direct UV rays. Typically, a welder who is regularly exposed to electric rays can cause damage to the skin and eyes. Therefore, if you work in an environment with UV rays or equipment that emits UV rays, always follow occupational safety rules such as wearing a mask and suitable clothing to prevent injury and protect yourself. skin and eyes.

* How to protect eyes against ultraviolet rays.

1. Wear glasses that help block ultraviolet rays.

If you wear glasses, always choose lenses with UV protection. Keep in mind that while they’re helpful, they don’t mean your eyes will be 100% UV protected. So, limit looking at the sky or windows that reflect sunlight as much as possible.

2. Wear sunglasses often.

Whenever you’re exposed to the sun, even indoors, wear sunglasses. Quality sunglasses must meet at least 99% UV blocking. They are usually labeled as UV absorbers up to 400mm. Note that the darkness of a sunglasses does not correspond to its UV protection. So don’t think that the darker the glasses, the better. The sun protection index on the glasses is much more important!
