In this section you can learn about the science behind sunscreens including:
Simple steps to stay sun safe
Seek out shade, particularly between 11am and 3pm, when the sun is usually at its most intense
Wear loose-fitting clothing and a wide-brimmed hat when in the sun and wear a good pair of sunglasses
Apply sunscreen 15-30 minutes before going out in the sun and re-apply every couple of hours throughout the day - you will need about a golf-ball-sized amount of cream for each application
Remember to re-apply when you emerge from cooling off in the water
Never use sunscreen to extend the time you would normally spend in the sun
Drink plenty of water, particularly in hot weather. Keeping your water intake up prevents dehydration and maintains a healthy bladder and kidneys; a healthy body helps to support healthy skin
Over-exposure to the sun is dangerous and can cause sunburn or heatstroke. Your skin will be hot, red, blistered, painful and swollen and you may have a severe headache or feelings of nausea. Get out of the sun, keep the skin cool, drink plenty of water and seek professional medical advice as soon as possible.
