Sun protection at the seaside: enjoy the sun without a care in the world

We generally associate the sun with positive things. This isn’t just because it provides warmth; it’s also because the brain releases serotonin, the ‘happiness hormone’, when sunlight hits our eyes. A good mood, inner peace, more energy and better sleep follow almost automatically. When the sun shines, we feel lighter, more active and happier. This effect usually sets in after just a few minutes outdoors. We already know, of course, that the sea also has numerous positive effects on our well-being. Combined – sun by the sea – this creates a real ‘happiness boost’.

The UVB rays in sunlight are also responsible for the production of vitamin D. We need it for healthy bones and teeth, a strong immune system, strong muscles and our metabolism. If we do not produce enough vitamin D, the result is tiredness, low mood and susceptibility to infections. It is also sunlight that signals to our body to stop producing melatonin – it is responsible for sleep.

In winter, we often struggle to get enough sunlight. This could also be one of the reasons why, during the darker months of the year, many people complain of low mood and seasonal mood swings, known as ‘winter blues’. In spring and summer, we find it much easier. Around 10 to 20 minutes of sunlight, ideally in the morning or late afternoon, is a good idea. Of course, we get much more sun during a holiday by the sea.

Water reflects up to 90 per cent of UV radiation, whilst light-coloured sand still reflects 25 per cent. This means that the sun’s rays are much more intense at the seaside than inland. The cooling sea breeze and fresh water also trick our senses: we don’t even notice that sunburn is already forming on our skin. It’s also important to know that UV radiation is particularly high in southern countries. Caution is therefore advised, especially between 11 am and 4 pm.

Sunlight consists of UVA and UVB rays. The former penetrate deep into the skin and can cause damage there. This can lead to premature skin ageing, increased wrinkling, and a higher risk of skin cancer. UVB rays are the ones that cause sunburn. They damage the upper layer of the skin. We now know that even just five severe sunburns in a lifetime can significantly increase the risk of skin cancer. Sunburn is not a souvenir – it is a warning sign!

Fortunately, however, we now have not only the necessary knowledge but also the ideal products to prevent sun damage. Enjoying the sun without regret or fear – it really is possible! Your most important tools are high-quality sun protection products. Here’s what you should look out for when choosing them:

• Use broad-spectrum sun protection that blocks UVA and UVB rays
• The fairer your skin, the higher the sun protection factor (SPF) should be. There is absolutely no reason not to use SPF 50 as a general rule.
• Reapply every 2 hours, especially after swimming or if you have been sweating heavily
• Radiation is at its strongest between 11 am and 4 pm. It’s best to stay in the shade during this time. Why not pop in for a coffee under a parasol during these hours?
• When snorkelling and swimming, it’s easy to lose track of time. Wear UV-protective shirts
• Make sure you also protect your head and eyes from the sun; hats and sunglasses are an absolute must-pack for your seaside holiday!
• Many sun creams contain chemical UV filters such as oxybenzone or octinoxate. These can damage coral reefs. Look for reef-friendly sun cream that is free from microplastics, nanoparticles and harmful filters
