Introduction To Massage Brunswick Heads

Solar radiations, which cause your bodies to tan, are thus classified: UV-A rays: those that penetrate deeply and are responsible for tanning and to a much lesser extent than rashes. They are also present in overcast and cloudy skies and their negative impact can occur even after years, thus necessitating Massage Brunswick Heads.

UV-B rays: they are potentially more harmful than UV-A because they are the main cause of sunburn and erythema but they also produce a stimulating action for the new synthesis of melanin and for vitamin D.

It is also good to remember that the sun is not the same in all parts of the world: near the equator and at high altitudes the intensity of radiation increases. Furthermore you have to be careful about the reflections produced by the water but also by the glaciers, because they multiply the rays making them arrive from every angle.

As everyone knows, sunscreens stand out based on their protection factor. The sun protection factor (Sun Protection Factor or SPF) measures the protective capacity of the solar product against UVB rays. It is a numerical coefficient (from 6 to 50+) calculated by comparing the amount of time needed to produce a scald on the protected skin with a filter or without a protective filter.

All this means that a cream with SPF 20 protection allows you to expose yourself to sunlight 20 times more than you could safely undergo without sunscreen. The filters contained in the creams can be of two types: physical filters: they are inert mineral substances such as titanium dioxide and zinc oxide which physically reflect sunlight. In the past it was those creams that once applied to the skin made it white; today thanks to the new more micronized formulas this effect is avoided thanks to Massage Brunswick Heads.

Chemical filters: they are substances that have the property of capturing the energy of UV rays returning them in the form of other energy, such as heat (salicylates, cinnamates, oxybenzone). The sunscreens have no expiration date, once opened, the creams come into contact with the air and can deteriorate. For all these reasons the ideal would be to replace them from year to year.

Knowing your phototype is the first step to understand which protection factor to use, or which number on sunscreen to choose. It is usually advisable to move in this way. In general it is advisable to apply sunscreen with SPF between 30 and 15 minutes before exposing yourself to the sun so as to give the skin time to absorb it and be better protected.
