What is the definition of a sunshade that won't burn?
If you're looking for a parasol, you want to choose one that won't burn you. However, even if you're simply told it's a "parasol that won't burn you," you might not know what criteria to use to choose one.
When choosing a parasol, you want to make sure you understand how much protection it will provide. Each parasol has a set "light blocking rate" and "heat blocking rate," so it's best to check these numbers before purchasing.
So, in the next section, we will explain the light blocking rate and heat blocking rate.
"Light blocking rate" and "heat blocking rate" that you may be too embarrassed to ask about now
Light blocking rate, heat blocking rate... Many people have heard of these terms, but don't really understand what they actually mean.
First of all, as the name suggests, the shading rate is a numerical value that indicates how much direct sunlight can be blocked. Products with a shading rate of 99.99% or higher can effectively block light, so damage is reduced.
The heat-blocking rate is a numerical value that indicates the ability to block heat. In the summer, when you use an umbrella, heat tends to build up inside, but if you choose one with a high heat-blocking rate, heat will not build up as easily, making it more comfortable to use.
How to Choose a Parasol ① Umbrellas with Black Interiors
When choosing a parasol, you can expect better results if you choose one with a black interior. You need to be careful not only of UV rays pouring down from above, but also of the glare that falls on the ground. Some parasols are coated with silver or other colors on the inside, but if you choose one of these, you will inevitably be more susceptible to damage from the reflected glare.
Black has the effect of absorbing ultraviolet rays, so by choosing an umbrella with a black interior, you can absorb the reflected ultraviolet rays and reduce their impact on your face, etc. This is why most parasols are generally black.
How to Choose a Parasol ② Umbrellas with a White Outer Surface
Umbrellas with a black interior are excellent parasols, but you also need to pay attention to the color of the exterior. Black is good for the interior, but it's best to choose an umbrella with a white exterior. As mentioned earlier, black absorbs ultraviolet rays and heat, so an umbrella with a black exterior will actually trap heat and make it more likely to get trapped inside. White is better for absorbing less heat, so it's best to choose an umbrella with a white exterior.
Taking all these points into consideration, you can see that choosing an umbrella with a white exterior and black interior will make you more comfortable under UV rays.
How to Choose a Parasol ③ A Parasol that Can Be Used in Both Sun and Rain
We mentioned that it's important to choose a parasol based on color, but you might feel that using it just as a parasol is a bit of a waste. It can be a bit of a hassle to have to prepare a separate umbrella. So, there are many parasols that can be used not only as a parasol but also as a rain umbrella, so it might be a good idea to choose one of those.
Parasols also come in long and folding types, so it's best to choose the one that's easiest for you to use. Long umbrellas have a larger surface area and can cover a wider area, while folding umbrellas are convenient because they can be stored in a bag. When choosing a parasol, design is important, but functionality should also be a priority.
summary
This time we have introduced the terminology behind parasols and how to choose one.
The key to choosing a parasol is functionality, so be sure to pay attention to the points introduced here.
Parasols play a very important role when going out on hot days, so you'll want to choose one that's easy to use. However, there are times when a parasol alone isn't enough protection. To protect yourself from UV rays more effectively, be sure to use sunscreen in addition to your parasol.
Taking proper precautions by using a parasol and sunscreen will help protect your skin and hair, which will also be very helpful in maintaining your health.
