Sunburn is the leading cause of skin cancer. Skin cancer is preventable, but it is often overlooked: nearly 5 million people in the United States are treated for skin cancer each year and over 9,000 people die of melanoma, the most severe type of cancer skin. The cause of skin cancer is usually due to overexposure to ultraviolet (UV) radiation, and sunburn at any age increases the risk of skin cancer and people with lighter skin tones are at greater risk. sunburn. in the United States recently conducted a study using data from 31,162 respondents from the National Health Interview Survey 2015. They investigated badociations between sunburn, sun protection, demographic characteristics and the fact of lifestyle golds. They also recorded the incidence of sunburn and the use of sunscreen. They published their results in JAMA Dermatology .
The researchers examined responses for five sunscreen behaviors:
- Staying in the Shadow
- Wearing a Broad-brimmed Hat
- Wearing a Long
- Regular Use sunscreen with sun protection factor (SPF)
Sun protection helps prevent sunburn
Researchers found that 34.3% of respondents had sunburn in 2015 This was more common in the group with younger and more active people and those more sensitive to the sun. Although the group of non-Hispanic whites suffered more sunburns, dark-skinned people still suffered from sunburn, which shows that race was not a determining factor in determining whether a sunburn was felt.
the shade (37%), using sunscreen (31%), and wearing clothes that reached the ankles (28%). These behaviors were significantly badociated with a lower prevalence of sunburn. Lifestyle factors that increased the likelihood of sunburn include sunless tanning, aerobic exercise, drinking and overweight
Sunscreen should be used with d & # 's 39, other forms of sun protection
The results of this study show that the use of sunscreen increases the probability of not having sunburn, but does not completely ensure the safety of the sun. 39, an individual against sunburn. The authors note that sunscreen should be used with other sunscreen methods, and people who use sunscreen may have a false sense of protection. Previous studies have also found that people who use sunscreen tend to stay longer in the sun.
Limitations of the study
The data obtained from the study are naturally prone to bias. Moreover, as it was a cross-sectional survey, the researchers only took into account the responses of the beginning and end of the study. The questionnaire also did not specify what types of sun protection behaviors were used in different contexts. Therefore, the cause and effect of sun protection behaviors and sunburn can be difficult to establish.
Tips for preventing sunburn
The authors make some recommendations to reduce the likelihood of sunburn.
Stay in the shade to reduce exposure to UV rays.
2. Plan long outdoor activities at a time when the sun's rays are less intense.
3. Use sunscreen in combination with other sun avoidance strategies.
The study found that those who apply sunscreen once during the day may have a false sense of protection. This explains why people who used sunscreen had a higher prevalence of sunburn.
The authors note that there is a lack of research on the most frequently used sun protection methods and their badociation with the factors causing sunburn. In addition, the authors note that the main factor of sunscreen intervention should not be based on the ethnicity of an individual.
For future studies, the authors suggest to consider sun sensitivity and lifestyles.
