1. Avoid or limit your exposure to the sun during peak hours
The sun's UV rays are at their strongest between 10am and 4pm, even on cloudy days and, particularly, at higher altitudes.
Some UV rays, especially longer wavelength UVA rays, can penetrate clouds and also, glass.
If you have to be in the sun during this period, use an umbrella or wear a hat. Protective clothing, such as long-sleeved shirts,long pants and sunglasses, will help to reduce UV exposure.
2. Apply sunscreen generously
Studies show that most people do not apply enough sunscreen and do not cover exposed sites evenly.
During a long day at the beach, a person should use around one half to one quarter of a 226g bottle. Reapply a generous amount every two hours.
Sunscreen should be reapplied immediately after swimming, towelling off or a lot of sweating.
But do not use sunscreen on infants below six months of age as they should stay out of the sun.
3. Avoid tanning parlours.
If you are looking for a healthy tan and think that tanning beds are better than being out in the hot sun, you are wrong.
Tanning beds expose your body to more UV rays and will increase your risk of skin cancer. There is no such thing as a healthy tan. A tan and sunburn are signs of skin damage.
