Sun Exposure Public Health Directives

Noise exposure and public health.

Exposure to noise constitutes a health risk. There is sufficient scientific evidence that noise exposure can induce hearing impairment, hypertension and ischemic heart disease, annoyance, sleep disturbance, and decreased school performance. For other effects such as changes in the immune system and birth defects, the evidence is limited. Most public health impacts of noise were already identifi...

Workshop on Mercury Exposure and Public Health

Exposure, effects, and public health challenges

EMBO reports (ER): The mission of the National Institute of Environmental Health Services is investigating the health risks of environmental chemicals and pollutants. There’s a whole zoo of compounds such as DDT, lead, tobacco smoke and many other pollutants that have eventually been banned or regulated after research demonstrated their health hazards. What do you think is now the most importan...

Sun Exposure and Psychotic Experiences

OBJECTIVE Sun exposure is considered the single most important source of vitamin D. Vitamin D deficiency has been suggested to play a role in the etiology of psychotic disorders. The aim of the present study was to evaluate the association between sun exposure and psychotic experiences (PEs) in a general population sample of Swedish women. METHODS The study population included participants fr...

Sun exposure measurements in populations.

Measuring ultraviolet (UV) exposure in human populations is a complex task. The dominant source of ultraviolet radiation for humans is sunlight, which is always a mix of both ultraviolet A (UVA, usually 320– 400 nm) and ultraviolet B (UVB, 320–280 nm). Ultraviolet C ( 280 nm) is filtered by the atmosphere and does not reach the earth’s surface. Researchers cannot separate the individual effects...
