Summary
Young adults used a UV monitoring system, reducing sunburn incidence. However, further optimization is needed, particularly for preventing sunburn during outdoor exercise.
Area of Science:
- Dermatology
- Public Health
- Mobile Health Technology
Background:
- Melanoma risk is linked to sunburn and UV exposure.
- Reducing sunburn in young adults may decrease melanoma incidence.
- Technological advancements enable real-time UV exposure monitoring and health interventions.
Purpose of the Study:
- To assess the feasibility of young adults using a UV monitoring system daily.
- To evaluate daily UV-B dose tracking, text message interventions, and web-based surveys.
- To examine self-reported sunburn and sun protection behaviors in young adults.
Main Methods:
- Recruited 42 young adults (18-39 years) via social media.
- Utilized the UV Guard system (UV dosimeter and smartphone app) for 28 days.
- Implemented a 3-period intervention with increasing intensity: UV-B dose, behavioral texts, and goal setting.
Main Results:
- Fewer sunburns occurred during the study (n=18) compared to the prior 28 days (n=30).
- Participants adjusted sun protection (38%) and outdoor timing (48%) based on UV-B data.
- Sunburns were most common during exercise and relaxation activities.
Conclusions:
- Young adults can use UV monitoring technology, but system optimization is required.
- While some behaviors changed, sunburn was not entirely prevented, especially during outdoor exercise.
- A significant majority (79%) were willing to continue using the system post-study.

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.

5.1K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

2.1K
The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell.

2.5K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

3.6K
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...

01:23Role of Skin in Vitamin D Synthesis
6.8K
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...
