How to choose sunscreen? Advice to vacationers.
All products that are designed to protect our skin from exposure to ultraviolet rays A (UVA) and B (UVD) differ in the degree of protection. SPF (Sun Protective Factor) is an abbreviation that stands for the degree of protection. This ratio ranges from 2 to 30 SPF. The higher its value, the longer you can enjoy the sun and sunbathe without harm to your health. To calculate the recommended sun exposure time, you need to multiply the sun protection factor by 15 to 20 minutes, so you get the time you need.

However, the means that protect from the sun (lotions, creams, ointments, etc.) is still necessary; The most important thing is to choose the right product for this.
Choosing sunscreen
The choice of sunscreen should be based on how dark your skin is, namely:
products with SPF from 2 to 4 - suitable for people who have naturally dark skin or for those who have had time to tan well.
products with SPF from 5 to 10 - suitable for those people who quickly tan and do not get burns. Suitable for sunbathers for several days.
products with SPF from 11 to 30 - (highest protection) - suitable for people with very pale skin, it is also recommended for children.
The best way to protect you from harmful sun rays is a sun filter cream. Look for the abbreviations UVA and UVB on the tube: this means that this cream will provide you with protection from two types of rays at once.
How to use sunscreen correctly
If your vacation takes place in hot countries, then for the first 4 days protect it with a cream, which has a factor of 20. As you are in the sun, the protection can be weakened to 7. Unfortunately, you cannot save on "factors": for example, by applying three layers with a factor of 10, you don't get 30! So be careful.
use sunscreenIf the Caribbean is still just a dream for you, and you are eating somewhere in the middle lane in the south of Russia for vacation, you can do with the most common domestic cream - a protection factor from 2 to 6. Remember that the protection will not start working immediately and therefore To avoid burns, apply the cream about 20 to 30 minutes before heading to the beach.
Read the instructions of the cream: if it says that it is waterproof, this does not mean applying one layer for the whole day. Refresh skin protection after 2-3 baths. It should be noted that wiping with a towel and grains of sand will gradually erase the protective layer of the cream, and as for the usual cream, it will generally be washed off when you first immerse yourself in water.

How to sunbathe not to harm your body
Overheating in the sun will increase sweating and your body will lose a lot of water and salt. It is not recommended to overheat for thin women. If the loss of water is more than normal, it will be harmful to health. As for people with weakened health, for them it is a risk of exacerbation of chronic diseases, as well as other disease processes that have gone unnoticed until that moment.
For those who have problem skin (pimples, acne) tanning is useful. The UV rays will cleanse the sebaceous glands and cause slight flaking on the skin. Along with peeling, dead cells and scales that clogged the mouth of the sebaceous gland will leave the surface of the skin; thanks to this, its functions will be restored.
Women with psoriasis can also benefit from soaking up the sun. It is forbidden to sunbathe for pregnant women, women who have chronic diseases, as well as the elderly. For people with heart problems, prolonged exposure to the sun can lead to swelling and a feeling of heaviness in the legs. If you have liver dysfunction or are hypersensitive to the sun's rays, tanning is contraindicated for you.
Sunbathe properly and have a good rest!
