Sunburn, presents as redness of the skin and swelling and can be associated with blistering, chills and fever.
The two types of UV light causing skin damage are UVA and UVB. UVB is more intense at causing a burn than UVA. The fairer your skin, the more chances you have of getting a sunburn. UV rays are also more intense between the hours of 10am and 2pm with about 65% of radiation reaching the earth between these hours. Areas of high altitude and reflective surfaces such as snow, ice and water will also intensify UV radiation.
To avoid your chances of a sunburn, limit your exposure between 10am and 2pm and apply SPF 50+ every few hours. Seek shade where possible between these hours and wear protective clothing.
If you have developed a sunburn then treat it immediately with cool baths, aloe vera lotions and drink plenty of water. However if you have suffered a deeper burn then you should seek medical advice.
Always seek professional advice to better suit your skin needs.
