Summary
Beach lifeguards face significant sun exposure risks, with many experiencing sunburn. This study quantifies their ultraviolet radiation exposure, highlighting the need for interventions to prevent skin cancer and promote early diagnosis.
Area of Science:
- Dermatology and Occupational Health
Background:
- Sunburn is a primary preventable cause of skin cancer.
- Beach lifeguards have prolonged occupational exposure to intense solar radiation.
- Quantifying sun exposure risk for lifeguards is crucial for public health.
Purpose of the Study:
- To quantify the sun exposure risk for beach lifeguards.
- To assess the relationship between occupational sun exposure and sunburn incidence.
Main Methods:
- A descriptive cross-sectional study was conducted in Southern Spain.
- 109 lifeguards completed questionnaires on sun exposure habits and knowledge.
- Personal dosimeters monitored ultraviolet exposure for a subset of participants.
Main Results:
- 77.1% of lifeguards reported at least one painful sunburn in the prior summer.
- Mean daily personal ultraviolet exposure was 634.7 J/m².
- Lifeguards frequently had skin phototypes III or IV, indicating moderate to high sun sensitivity.
Conclusions:
- Beach lifeguards experience high solar radiation doses and sunburn rates.
- Intervention strategies are needed to modify sun exposure behaviors.
- Reducing skin cancer risk and promoting early diagnosis in lifeguards is essential.

01:23Role of Skin in Vitamin D Synthesis
6.7K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

01:28Survey Safety
237
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

01:19Pigmentation
3.5K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:
