How to have eco-friendly fun in the sun…
TRADITIONAL (generally big brand) sunscreens often contain chemicals, including Oxybenzone and Octinoxate, that can harm or kill coral and marine life when they enter our rivers and oceans.
And of course, many come in bottles, often made from virgin plastic, and include hard to recycle spray mechanisms.
Every time we bath or shower, wash our hands or swim outdoors having applied sunscreen, we risk introducing potentially toxic and harmful chemicals into the water system.
Coral reefs are vitally important ecosystems and often referred to as the “rainforests of the oceans”.
They help to store Carbon, to protect against costal erosion and to provide essential habitats for thousands of species. Their future existence is threatened by factors including climate change, overfishing and other forms of pollution.
The Marine Conservation
Society (MCS) recommends using marine-safe sunscreen and has said: “Unfortunately sunscreens have been shown to have an impact on the marine environment – not just coral reefs but also other marine organisms. Oxybenzone and Ethylhexyl Methoxycinnamate (Octinoxate) are particularly harmful and the MCS recommends avoiding sunscreens with these ingredients.”
When choosing a sunscreen, aim for one that is both organic and cruelty free where possible.
Applied and used correctly, sunscreen can help to reduce the risk of sunburn, skin damage, ageing and skin cancer. It is important to remember though that our bodies need sunlight and Vitamin D to remain healthy. Indeed, various studies have suggested that Vitamin D can help to reduce our risk of being as severely affected by communicable viruses and certain illnesses.
Sunscreens generally contain an emulsion (a cream, lotion, milk, oil, gel or foam), which works to carry an active ingredient (that either absorbs or reflects UV rays) designed to protect your skin.
SPF simply stands for ‘sun protection factor’ and is a measure of the ultraviolet B radiation (UVB) protection provided. SPFs are rated on a scale of between two and 50+, with the latter offering the greatest protection.
Sunscreens should also feature a star rating that indicates the level of ultraviolet A radiation (UVA) protection that is provided. In the UK, sunscreens are rated up to a maximum of five stars, with this offering the highest level of protection.
We have been taught to aim for a high level of SPF protection when buying sunscreen, but many people do not realise that the difference between different factors is relatively small. For example, a sunscreen labelled SPF30 will protect your skin against 96.7% of the harmful UV rays it may be exposed to during hot and sunny weather. While an SPF50 sunscreen will protect against around 98% of the UV rays.
As a simple rule of thumb, if you multiply a sunscreen’s SPF factor by 10, this will indicate approximately how long the sunscreen may provide your skin with protection for.
For example, a SPF30 sunscreen will at least partially safeguard your skin against sunburn for up to 300 minutes, or up to five hours, compared to just 10-15 minutes if no sunscreen at all is applied. That said, it is recommended to reapply all sunscreens every two hours or so to top up your protection.
In the UK, the NHS says: “Do not rely on sunscreen alone to protect yourself from the sun. Wear suitable clothing and spend time in the shade when the sun is at its hottest. When buying sunscreen, the label should have a sun protection factor (SPF) of at least 30 to protect against UVB and at least 4-star UVA protection. Make sure the sunscreen is not past its expiry date. Most sunscreens have a shelf life of two to three years.”
Ocean/reef safe, Vegan and cruelty free sunscreens that we would recommend include Green People (SPF 30), Badger (SPF 30), Child’s Farm (SPF 50), Neal’s Yard (SPF
30) and Lucy Bee (SPF 30). Shade is also a solid option but note that it is SPF25. The company writes: “As SPF25 protects you from 96% of the sun’s harmful UVB rays which cause burning, we believe that users will not be as complacent as they would be about using a high SPF. Also, very high SPF is only achievable with chemical active ingredients, something we’re trying to avoid.”
Please note that in some cases different versions are available for adults and children but otherwise don’t let any branding deter you – they are fine for children and adults alike.
