SUNCREAM: HOW DO I CHOOSE THE BEST ONE?
BBC Science Focus
|Summer 2022
A report from Which? found that several 'mineral' suncreams don't provide adequate protection
Summer is here, and much of the UK is feeling the heat. As temperatures rise, more and more of us head outside for barbecues, picnics and sunbathing. However, anyone who's turned lobster-red after a few hours outdoors will know that suncream is essential, even in the UK.
But which suncream should you choose? Lotion, spray-on or roll-on? Chemical or mineral? And can you get away with a moisturiser with SPF?
WHAT SHOULD I LOOK FOR ON THE BOTTLE?
The first thing to look for is the Sun Protection Factor, or SPF. This measures how much the suncream will protect you against UVB, the higher-energy, shorter wavelengths of the Sun's UV light.
"SPFS are rated on a scale of 2 to 50+," says Prof Brian Diffey of the British Association of Dermatologists. "We recommend an SPF of 30 or more as a satisfactory form of sun protection." In addition to SPF, make sure the suncream also displays a star rating. This is a measure of its protection against UVA, which is the lowerenergy, longer-wavelength type of UV light. However, a high star rating isn't enough: this only measures how much UVA the suncream blocks in comparison to UVB, so a high star rating and low SPF is still low protection overall.
"A sunscreen with an SPF of 30 and a UVA rating of four or five stars is generally considered as a good standard of sun protection, in addition to shade and clothing," says Diffey.
IS THERE ANY DIFFERENCE BETWEEN SPRAY, LOTION, CREAM, STICK OR ROLL-ON SUNCREAMS?

HOW DIFFICULT WOULD IT BE TO FLY THROUGH THE ASTEROID BELT?
In the 1980 film Star Wars: The Empire Strikes Back, Han Solo and friends try to escape pursuing imperial forces by flying through an asteroid field. Droid C-3PO remarks, \"the odds of successfully navigating an asteroid field is approximately 3,720 to 1\". The scene depicts a chaotic, dense field of rocks swirling and spinning through space. This scenario has been played out many times in the cinema.

HOW CAN I BE MORE PERSUASIVE?
Most of us like to think we're rational people. If someone shows us evidence that we're wrong, we'll change our minds, right? Well, not necessarily, because it's not always that simple. Being wrong feels uncomfortable and sometimes threatening. That's why changing someone's mind is often much harder than it seems.
