There's nothing like a sunny day to boost your mood, but spending time in the sun can be risky if you don't take the proper precautions. While small amounts of sunlight are good for your health, too much sun exposure can lead to serious long-term consequences, including skin cancer and damage to your eyes.
Find out more about the sun's effects on your body, and learn the simple steps you can take to help protect yourself from its more damaging effects.

Sun safety tips for home and on holiday
There are many ways you can reduce your exposure to the sun and protect your skin from UV rays. Here are your sun protection basics:
- Use a broad-spectrum sunscreen (one that protects from both UVA and UVB rays) with an SPF (sun protection factor) of at least 30 on all areas of exposed skin every day, even if it's cloudy or you're mostly indoors. Remember that UV rays can penetrate clouds and windows.
- Use a higher SPF if you're going to be outdoors for longer periods of time. Apply generously, and remember to reapply frequently (at least every two hours), especially if you've been swimming or sweating.
- Go indoors or seek out shade between 11am and 3pm, when the sun's rays are strongest. A good rule of thumb is to watch your shadow: when it’s shorter than your height, get out of the sun.
- Wear a hat with a broad brim to help protect your face, neck and ears, and cover your arms and legs with a long-sleeved top, trousers or a long skirt. Remember that fabric with a tighter weave offers more protection than a looser weave. You can tell how much sun is getting through by holding the fabric up to the light.
- Protect your eyes with sunglasses that offer full UV protection. In the UK, this means they should display a UV 400 label; the British Standard or CE mark (BS EN 1836: 2005); or a label that says they provide 100 percent UV protection.
- Babies and children have very sensitive skin, so it's important to make sure they're well covered. Use a sunscreen with a high SPF and make sure they're protected with a hat, sunglasses and the appropriate clothing.
- Remember that a tan (from the sun or a sunbed) does not protect your skin from the sun; in fact, it’s a sign that damage has already occurred. If you prefer to have darker skin, a fake tan is a safer option, but remember that it does not provide sun protection either.
