How are key environmental factors linked to public health and wellbeing? This blog addresses all aspects of natural and human built environments, provides latest updates and overview of key health indicators.
Food, drugs, air and everyday products like soap, cloth and grocery receipts are polluting our bodies with hundreds of toxic chemicals. New chemicals are constantly being introduced into our environment and the effects of most of them on human health are not known. About 30% of human diseases are due to environmental exposures as genetics is not the whole story. Whether rich or poor, our bodies are burdened with toxic waste. High socioeconomic status means more mercury and arsenic........ Read more »

The environment plays a significant role in our health. We are exposed to multiple physical, chemical and biological challenges, including information - like news and gossip stories related to health and wellness. How exactly is it affecting us? University of Pennsylvania researchers surveyed over two thousand US adults 40 to 70 years of age on how they scanned for information about specific health behaviors. The researchers followed up one year later to see how participants' behaviors chang........ Read more »

Asthma sufferers know that when it rains it spores - as fungi and mold get moving through the air. But many don't realize that the most dangerous month for children's asthma symptoms is dry September. A study of hospital data found the spike in admissions in two to three weeks after the return to school. It happens in the United States, the United Kingdom, Mexico, Israel, Finland, Trinidad, and Canada, where 20% to 25% of all childhood asthma exacerbations requiring hospitalization have occurred........

The jury is still out whether Angelina's choice is brave or fearful, but the fact remains: having or not having the "bad" genes is not enough to develop or avoid developing breast cancer. As a matter of fact, only 5% to 10% of breast cancer cases result directly from inherited gene defects. Check it yourself, by using this decision tool developed in Stanford. Even though for members of some families with BRCA mutations the risk may be as high as 80%, this could be because of environme........ Read more »

Nothing is certain, but blood pressure does increase in the end of winter and beginning of spring. According to Aurametrix users and google statistics. As a matter of fact, it highly correlates with tax fever - as found by Google Correlate algorithm comparing millions of web queries. But the reason for raising blood pressure is not always taxes. Seasonal variation in blood pressure was noticed and described more than 50 years ago and was connected to periods of decreasing outdoor temperature. ........ Read more »

Worst of flu season may be over. But you can still catch a chill. If you shake hands with lots of sick people, for example. Or don't keep sufficiently warm. Yes, your mother has told you, and you thought it was just an old wives' tale, but it wasn't. Scientists (Johnson and Eccles, 2005) provide evidence that cold exposure may induce cold symptoms without any contact to sick individuals. As we all carry dormant (sub-clinical) infections in our nose, genitals and other parts of the body, and thes........ Read more »

An apple doesn't fall far from the tree. So if you don't like apples, trees won't like you either. And the other way around.If your mother ate apples during pregnancy, she might have protected you from asthma. And if you like apple juice, this might help you avoid chronic wheezing issues. Research has already proven these and many similar connections. Now a new study suggests that eating apples could also help you cope with seasonal allergies - particularly with allergies to ........

Fewer people caught the flu this season compared with past years. And many more apps tracking the flu have been developed. Any relationship between these two trends?Of course, less flu could be just the result of fewer mutations in bugs, warmer weather and more vaccinations. Yet the power of good software - such as google flu trends, twitter-based trackers and numerous apps can not be underestimated. Thanks to these tools, we are now more aware (and more afraid).The flu is inher........ Read more »

Environment can significantly affect human health. And the risks are not limited to air pollution, seasonal allergies, tainted water or chemicals in food. Our life dramas are set against the backdrop of world events that contribute to environmental health too, to a lesser or greater extent.How does springing clocks forward affect our lives?Hopefully, not much financially. Despite earlier predictions that average stock market returns are likely to be lower on Mondays following time changes (........ Read more »
