Do we need sunscreen indoors?

It's actually funny, we usually apply cream well on the beach or in a café. But at home we are suddenly more careless. We seem to forget that it's really the same sun that shines in the garden or on the playground. How well you should apply sunscreen outside depends on the UV index. What was that again? These pictures prove that sometimes, even indoors or in the car, it's better to apply a layer of sunscreen ...

Sunshine? 

Sun protection is particularly important from April onwards. This is when the sun is higher in the sky again, which increases its intensity. This means that more UVA and UVB rays reach the earth. The UV index shows exactly how strong the sun is. The higher it is, the more radiation there is (and the better you need to protect yourself from the sun). From index 3, the general recommendation is to apply sun cream. In most countries, this can be the case from April to September. But if you want to delay the aging process, it is better to apply sunscreen every day: even in winter and fall, when the sun is less intense. Because a sun protection product is the perfect anti-wrinkle cream.

Different SPF in spring

When choosing the right SPF, it is also advisable to consider the UV index (and therefore the time of year). From October to March, a factor of 30 is often sufficient, but when the sun starts shining in April, a minimum of SPF 30 is recommended. However, I apply an SPF 50 on my face and hands always. If you have fair skin or pigmentation spots, it is better to use factor 30 in the fall and winter too. If you go outside, reapply every two hours. And also apply an extra layer if you have been swimming or sweating a lot.

Sun also penetrates through glass

Also apply cream in the car

So you should also apply sunscreen when you are sitting in the car. This is because the glass used for the side windows of cars often still lets a lot of UVA radiation through. Fortunately, car windscreens nowadays are usually made of laminated safety glass (glass with a plastic layer in between). This glass stops all radiation.

 

Does the window glass provide security at home?

Unfortunately, the glass in house windows is usually not laminated safety glass, but normal glass. And if a window is made of this glass, you can assume that it lets UVA radiation through. So if you like to eat breakfast by the window or are lucky enough to be able to look outside while you work, you should also protect yourself indoors with sunscreen.

Do you apply cream differently indoors than outdoors?

But how often do you need to apply cream when you're indoors? Even every two hours? There was a study was conducted to exactly exam this.  The result: after just one application, you remain fairly well protected from the sun during the day, but then you should not touch your face too often and apply enough cream. You can therefore apply in the morning and then go outside during your lunch break without having to reapply. Of course, if you stay outside, reapply every two hours.
