Sunburn - it can ruin a holiday by causing you pain, not to mention put you in danger. The severity depends on your skin type and side effects include stinging, swelling, blisters, itching, headaches and even fever or chills.
You may not feel up to popping to the shop for treatments so we have some home remedies which will ease the discomfort and help soothe skin.
One of these is resting a cold, damp towel or flannel over the affected area. Leave it on for around 15 minutes to cool your skin down, and rest a separate one on your head to stop the heat from spreading all over. A cool bath will help too, or if you have a shower with light pressure you can use that (power showers may hurt the skin). Be sure to pat yourself dry rather than rub as this will only irritate more and could result in unnecessary peeling.
On the topic of water, you should drink plenty of the clear stuff every day to keep your body hydrated. The only way your skin can heel and cells can grow is by keeping hydrated, and you'll also feel cooler after drinking a pint of cold water.
Weak squash and herbal teas also count, so there are no excuses for you not to guzzle down plenty of H20.
Moisturising is also an important step as the last thing you want is your skin to go dry - it will become even sorer. Choosing a body moisturiser containing aloe vera can help soothe things too. The plant is known for its pain-relieving effects and for treating burns thanks to its slimy liquid containing vitamins, saponins (which clean and disinfect) and minerals.
Tea tree and witch hazel are other options, both are anti-inflammatory and antiseptics.
Whatever you do, don't pick skin, pop any blisters or apply products with harsh chemicals like perfume until it's fully healed. Let this be a warning to you - wear higher SPF and spend less time in the sun in order to prevent it from happening again.
