Most people think about sun protection on beach holidays and forget it the rest of the year. Yet ultraviolet (UV) radiation reaches us on the walk to work, while gardening, during a lunchtime stroll and even on bright cloudy days. Over time, UV exposure contributes to sunburn, premature skin ageing and a higher risk of skin cancer.
The aim is not to avoid the outdoors. Time outside is good for body and mind. It is about building a few simple sun protection habits into everyday life so they happen without much thought.
This article is general information, not medical advice. If you have questions about your own skin, a skin condition, or medicines that can make skin more sensitive to sunlight, see a dermatologist or another qualified health professional.
Understand UV and the UV Index
Sunlight contains two types of UV that matter for skin. UVB is the main cause of sunburn. UVA penetrates deeper into the skin, contributes to skin ageing and can pass through clouds and window glass. Both play a part in skin damage.
The UV index, shown in many weather apps and forecasts, measures how strong UV radiation is on a given day. The higher the number, the stronger the UV and the faster skin can be damaged. Health organisations generally recommend sun protection when the index reaches 3 or above. Checking the UV index each morning, just as you would check for rain, is an easy habit to build.
Sunscreen Basics
Choose broad-spectrum protection
“Broad-spectrum” on a label means the sunscreen is designed to protect against both UVA and UVB. Many dermatology organisations recommend a broad-spectrum sunscreen with an SPF of 30 or higher for everyday use. Water-resistant formulas are useful if you will be swimming or sweating.
Apply enough
Most people apply less sunscreen than they need, which reduces protection. Be generous and cover all exposed skin evenly. Areas that are easy to miss include the ears, the back of the neck, the tops of the feet, the hairline and the backs of the hands.
Reapply
Sunscreen wears off. A common guideline is to reapply about every two hours when you are outdoors, and straight after swimming, heavy sweating or towel-drying. Keeping a small bottle in a bag, car or desk drawer makes this easier.
Check the date
Sunscreen can lose effectiveness over time, so check the expiry date and replace bottles that are out of date or have been stored somewhere very hot for long periods.
Sunscreen Is Only One Layer
Sunscreen works best as part of a wider approach. Combine it with the following habits:
- Seek shade, especially in the middle of the day, when UV is often strongest. A handy check is your shadow: if it is shorter than you are, UV levels are likely to be high.
- Cover up with clothing such as long sleeves and trousers in tightly woven fabrics. Some clothing is labelled with an ultraviolet protection factor (UPF).
- Wear a wide-brimmed hat that shades the face, ears and neck. Baseball caps leave the ears and neck exposed.
- Protect your eyes with sunglasses that state they block UV, ideally a close-fitting or wraparound style.
- Avoid sunbeds, which expose skin to concentrated UV radiation.
Situations People Often Overlook
Cloudy days. A large share of UV can pass through light cloud, so skin can burn on days that do not feel especially sunny.
Reflective surfaces. Snow, water and sand reflect UV, increasing exposure. Skiers, sailors and beach-goers often burn more than expected.
Altitude. UV is stronger at higher altitudes, which matters for hikers and mountain holidays.
Driving and window seats. Window glass blocks much of the UVB but some UVA can still pass through, so long daily drives can add up.
Short, repeated exposures. The daily school run, outdoor lunch breaks and weekend gardening add up over a year.
Protecting Children
Children’s skin is delicate, and sunburn in childhood is something to avoid. Hats, shade, sun-protective clothing and sunscreen for exposed skin all help. Babies are particularly sensitive, and health services generally advise keeping young babies out of direct sunlight. Ask a doctor, pharmacist or health visitor for guidance on sun protection for infants.
Check Your Skin
Get to know your skin, including moles and freckles, so you notice changes. See a doctor promptly if a mole changes in size, shape or colour, if a spot bleeds or itches, or if a sore does not heal. Early checks matter.
Making It a Habit
The easiest way to stay protected is to tie sun habits to things you already do: apply sunscreen after brushing your teeth, keep a hat by the door, and glance at the UV index when you check the weather. Small, repeated actions protect your skin far more than an occasional big effort.

Frequently Asked Questions
Do I need sunscreen on cloudy days?
Often, yes. A large part of UV radiation can pass through light cloud, so skin can still be damaged on overcast days. Checking the UV index in a weather app is a simple way to decide whether protection is needed.
How often should I reapply sunscreen?
A common guideline is to reapply about every two hours while you are outdoors, and immediately after swimming, sweating heavily or drying off with a towel, even if the product is labelled water-resistant.
What does SPF mean?
SPF stands for sun protection factor. It mainly describes how well a sunscreen protects against UVB, the type of UV that causes sunburn. For protection against UVA as well, look for a product labelled broad-spectrum.
Is a darker skin tone protected from the sun?
Darker skin has more natural protection against burning, but it can still be damaged by UV. People of all skin tones benefit from shade, protective clothing and sunscreen, and should check their skin for changes.
