Time frolicking outdoors in the sun is as an integral part of summer. However, sunlight contains ultraviolet (UV) rays that promote skin damage and aging, and increase the risk of skin cancer. The Skin Cancer Foundation warns that sunscreen is critical during time outdoors, regardless of skin type. While new FDA sunscreen regulations promise to provide consumers with more accurate information about the degree of protection their sunscreen is providing, the CDC warns that sunscreen is only one part of the protective equation, and recommends protective clothing and judicious use of shade during intense sunlight hours.
Android App for Those Concerned about Cell Phone Radiation
While the link between cell phone use and brain tumors has not been scientifically established — in fact, a recent U.K. Health Protection Agency group review of the scientific literature concluded that there’s no convincing evidence that cell phones cause cancer — concerns about overexposure of brain cells to radiofrequency waves (RF) from cell phone antennae continue to circulate. While there may not be a well-established link between cell phone use and cancer or tumors, there’s nevertheless evidence that cell phone use alters brain cell metabolism (the rate at which brain cells burn sugar for energy) [1]. The significance of this finding is currently unknown, which makes some cell users nervous.
A company called Tawkon (pronounced “talk on”) has developed an app for the Android phone that can predict — not detect, since phones don’t have the ability to detect radiation — when a phone is most likely to be emitting high levels of RF on the basis of internal measurements, such as how strong the cell signal is.
No Convincing Evidence that Cell Phones Cause Cancer
A new report by the U.K. Health Protection Agency’s independent Advisory Group on Non-ionising Radiation (AGNIR) has concluded that there is no convincing evidence that mobile phone technologies cause adverse effects on human health. The report updates AGNIR’s previous review in 2003 that considers the scientific evidence on exposure to radiofrequency (RF) electromagnetic fields, which are produced by mobile phone technologies and other wireless devices, such as Wi-Fi, as well as television and radio transmitters.
Berries May Help Prevent Age-Related Decline of Brain Function
With humans living longer than ever before, diseases associated with aging are becoming a major focus of medical research. Neurodegenerative diseases, such as Alzheimer’s disease, are a major source of concern to aging adults. This is because such diseases not only lead to death, they do so through a particularly frightening route that includes loss of independence, memory, function, and personality. All adults experience a decline in certain aspects of brain function as they age. Memory, speed of cognition, and reasoning are among the functions most affected [1]. The effects of aging on cognition appear to be due to atrophy of brain tissue in particular regions, especially the prefrontal cortex and parietal cortex [2], as well as decreased neurotransmitter levels.
Health Hazards of Mobile Devices
The age of mobile devices reached a milestone last month. According to the latest research from the Pew Internet and American Life project, as of February, just over half of all U.S. adults own a smartphone [1]. In fact, some readers are viewing this on a mobile device right now. If you’re reading this on your iPad or smartphone: how is your neck positioned? How close are you holding your device to your face? Staring down and squinting at a small, bright screen for several hours a day clearly isn’t healthy, and as a reminder the infographic below “Are Mobile Devices Destroying Your Body?” illustrates some of the health risks of mobile devices and provides some prevention tips.
