Staying in the shade is an effective way to reduce sun exposure, e.g. you can use trees or an umbrella - what is most important is that it casts a dark shadow. 

Though being in the shade it is still recommended that you use other protection - such as clothing, hats, sunglasses and sunscreen.

These guidelines are not exhaustive and you should always seek advice and guidance from professional if you have any doubts.

What you need to know about sunscreen

• Apply water resistant SPF 30+ (or higher) – SPF 30 blocks 97% of UVB rays.
• The ideal time is 20 minutes before you go outdoors and every two hours afterwards.
• Most people dont apply enough sunscreen - apply at least a teaspoon for each limb, front and back of the body and half a teaspoon for the face, neck and ears.

What does SPF and water resistant mean?

• SPF means sun protenction factor and is a measure of how well it protects the skin from sunburn. A 30 SPF sunscreen would provide 30 times the protection of no sunscreen. 
• Water resistant means that it does not come off the skin during swimming or exercise, provided it is not wiped off. The FDA defines water resistant sunscreen as meaning that the SPF level stays effective after 40 minutes in the water. While a label may state a sunscreen is '4 hours water resistant', sunscreen still needs to be applied every two hours to maintain the same level of protection and if you are taking a dip regularly you also need to reapply.

What to think about when choosing your new hat?

• A 3 to 6 centimetres brim all around is ideal because it protects areas the ears, eyes, forehead, nose, and scalp.
• A dark underside to the brim can also help lower the amount of UV rays reaching the face from reflective surfaces such as water.
• Choose a hat made with closely woven fabric – if you can see through it, UV radiation will get through. 
• If you don’t have a good hat available, you can wear a large handkerchief or bandana.
• Sunscreen is still recommended. 

Tips about sunglasses

UV-blocking sunglasses are important for protecting the delicate skin around the eyes, as well as the eyes themselves. Here are a few tips before buying new ones.

• There will most likely be a label on the glasses stating they protect against UV rays – if in doubt ask an optician.*
• Darker glasses are not necessarily better because UV protection comes from an invisible chemical in or applied to the lenses, not from the color or darkness of the lenses. 
• Sunglasses should be worn outside during daylight hours.
• Sunglasses are as important for children as they are for adults. 

*The standards may differentiate from country to country why you should check up on local recommendations before you go.
