Health – The burning question

It is strange to think that a volcanic eruption in Tonga in January could make my face burn on Labour Day, but researchers have speculated that the explosion temporarily damaged our ozone layer in New Zealand, allowing our sun to burn us quicker this summer. Your choice of sunscreen this year has never been more important. So what do you need to know to choose the right sunscreen for you and your family?

• Chemical versus physical? 

There are two main types of sunscreen. A chemical sunscreen absorbs UV rays, converts them into energy and releases it from the body. Whereas physical sunscreens simply deflect the rays, without the need for this chemical reaction. Both come with benefits and drawbacks. For instance, physical sunscreens are less likely to irritate the skin and chemical ones are easier to rub in.

• Spray or lotion? 

While sprays seem more convenient, to ensure a uniform covering over your body, you will still need to rub sunscreen in. Using a lotion means you don’t have to suck in all the aerosol while doing so!

• Water resistant or not? 

If you’re planning on swimming (or for that matter simply sweating) then water resistance should be a factor in choosing your sunscreen. Always remember to reapply after drying off and every two hours.

• What SPF is best? 

The reality is that we are not the best at applying our sunscreens, so it is best to have a higher safety margin and use at least SPF 50.

• Face or body? 

Since the skin on the face and body differ, it is worth considering separate sunscreens for each. Face sunscreens with tint can provide your face with that healthy glow. And don’t forget your lips – they are very sensitive and don’t respond well to sunburn!

• Environmentally friendly? 

The term ‘reef safe’ means the sunscreen is free of chemical ingredients and small particles known to damage and potentially kill coral reefs, which may be a factor in choosing a sunscreen, especially if you’re headed overseas.

• Correct use

If you think the sunscreen didn’t work, consider user error. The ‘sunscreen teaspoon rule’ states that for an adult, the recommended application is one teaspoonful (5ml) for each arm leg, body front, body back and face (including neck and ears) which means you should use seven teaspoons for each application. Also remember if you are using a chemical sunscreen you’ll need to wait 20 minutes for the chemical reaction with your skin to take place before you go outside.
