There are a huge number of tips:
sit in the shade all the time
sit in the shade during "daylight hours":
- from 11 to 15
- from 10 to 16
However, no one gives clear instructions, everyone has only common words ☹ ️
Why? The intensity of the sun's ultraviolet light and the likelihood of a burn are affected by MANY factors:
✔️ geographical latitude
✔️ altitude above sea level
✔️ cloud cover
✔️ time of year
✔️ time of day
✔️ skin phototype
It is impossible to take into account everything "on a whim". That's why we hear stories like "they defended themselves, but they still burned down." This question will be answered by the service https://sunburnmap.com/
, which, in fact, the material is about.
1) The name of your locality
2) Skin type
✔️ The exact alignment of the HOURLY change of the UFI around you
✔️ The exact amount of time you can stay in the sun without protection and not burn (checked personally, not burned)
✔ ️ Understanding that the spf50 cream will give protection for several hours, however, this is not a reason to prolong your stay in the sun.A few important points
1️⃣ Take the SPF 50 cream and do not skimp on the brand. According to research SPF more than 15 is enough (fda.gov), however, the remaining 35 points will smooth out the sharp corners like:
forgot to reapply
applied a small amount
part of the cream was washed off by water
very light skin, etc.
2️⃣ Remember that the cream is only one of the ways to protect yourself. It works optimally as an addition to:
Clothing that protects the skin from the sun;
Glasses marked with € cat 2,3,4 (no one wants cataracts).
Ideally, of course, to sit in the shade with UFI 3+, but let's be honest-who is going on vacation just for this?)
3️⃣ It is possible to burn at high UFI and at cloudy skies and relatively low temperatures.
4️⃣ The resulting tan does NOT protect against burns.
5️⃣ In the mountains, snow and altitude can double the UFI. Be careful.Now is the time to save the link to your bookmarks, so as not to flap your wings before you leave!)
