A new way of thinking about ice packs for sore muscles
By Roberta Attanasio We all know ice packs—many of us reach for them soon after an injury to reduce pain or inflammation. Think of strained muscles, sprained ankles, and so on. But is this the right approach to accelerate healing? A 2019 article from The Washington Post states: “Today, ice packs have become as ubiquitous as aspirin—they’re a fixture in every athletic training facility and sold in drugstores throughout the country. Cold baths and ice tubs have also become one of sport’s most popular recovery aids. Nearly every high school, college and pro trainer’s room has at least one ice tub, and over the last 10 or 15 years they’ve…

Spending time in nature may improve emotional wellbeing during the COVID-19 pandemic
By Roberta Attanasio The toll that the COVID-19 pandemic is taking on mental health, for both children and adults, is unequivocal. An article published in The New York Times in February 2021 highlights a dire situation: “Since the first coronavirus case was confirmed in the United States more than a year ago, the number of people in need of mental health services has surged. But many say that they are languishing on waiting lists, making call after call only to be turned away, with affordable options tough to find. Providers, who have long been in short supply, are stretched thin.” According to an article published at about the same time in…

Children exposed to air pollution are more likely to develop disease later in life
By Roberta Attanasio We have known for quite some time that the first years of life represent a unique “window of vulnerability”—exposures to environmental chemicals at this time influence cellular programming in ways that shape health and disease in later years. For example, recent research shows that there is a significant association between multiple prenatal and early life exposures to indoor pollutants and the degree of allergic sensitivity in 2-year old children. In other words, babies exposed to air pollution during prenatal life and for the first several moths after birth, up to 2 years of age, are at higher risk of developing allergic sensitivity. Now, results from a study published…

Is women’s menstrual cycle linked to that of the Moon? A new study may provide answers
By Roberta Attanasio In the rush of modern life, we often fail to notice the link between our biological rhythms and those of the natural world. In many animal species, the reproductive cycle is synchronized with different Moon phases—most likely because reproductive success is facilitated when different individuals within a species behave in the same way at the same time. The moon phases act like a guide to synchronize courtship, mating, and other reproductive behaviors. But what about women? To some people, a connection between the menstrual cycle and the Moon cycle is apparent because their length is very similar—about 29 days. Others argue that there is no connection, as the…

Wildfires and fireworks may pollute the air inside your home
By Roberta Attanasio 4o years ago an article published in The New York Times highlighted the threat of indoor air pollution: “The air you breathe in your home or office may be hazardous to your health – more dangerous, in fact, than the outdoor air in the most polluted of cities. This is especially so during the cold months, when windows and doors are kept tightly shut and homes, schools and office buildings are made as airtight as possible to conserve energy.” While at the time awareness of the problem was still limited, we now know—on the basis of scientific evidence— that the air within homes and other buildings can be…

Measles outbreak in Samoa: potential effects on COVID-19
By Roberta Attanasio Measles—one of the world’s most contagious diseases—induces immune amnesia, an anomaly of the immune system that results in increased susceptibility to infections by other pathogens. Not surprisingly, there are concerns globally about populations that have recently experienced measles outbreaks. These populations could be at elevated risk of developing more severe COVID-19 illness, resulting in increased mortality. The emergence of the current COVID-19 pandemic in the first months of 2020 occurred closely after a global resurgence of measles. According to the World Health Organization (WHO), by November 2019, measles case numbers had tripled compared with the same period in the previous year. Measles spreads easily when an infected…

The unborn baby: Healthy pregnant mothers exposed to air pollution from road traffic inhale toxic particles that may end up in the placenta
By Roberta Attanasio According to a recently published study, carbon and metal particles from road traffic, once inhaled, reach one of the many places where we would rather not find them—the unborn baby’s life support system, best known as placenta. Lead author Jonathan Grigg said: “Our study for the first time shows that inhaled carbon particulate matter in air pollution, travels in the blood stream, and is taken up by important cells in the placenta.” For the study, researchers analyzed placentas from 15 healthy non-smoking women, donated after the birth of their children. All women delivered healthy babies. However, they lived in an environment that exposed them to high levels…

Allergies in Young Children: Effects of Exposure to Multiple Air Pollutants During Prenatal and Early Life
By Roberta Attanasio The frequency of allergies in children keeps rising rapidly worldwide, but it’s not clear why. However, it is acknowledged that developing even one type of allergy early in life is almost like turning on a switch—it can start children on a path to more. “The progression of skin allergies to asthma and allergic rhinitis is called the allergic or atopic march. Atopic dermatitis is an itchy, inflammatory skin allergy that, before 1960, affected fewer than 3% of children; by the 2000s it had increased to around 20%. A child with atopic dermatitis is more likely to develop other allergic conditions or symptoms. For example, about 70% of…

As coal mining declines, community mental health problems linger
By Roberta Attanasio The U.S. coal industry is in rapid decline, a shift marked not only by the bankruptcy of many mine operators in coal-rich Appalachia but also by a legacy of potential environmental and social disasters. As mines close, states, the federal government and taxpayers are left wondering about the costs of cleaning up the abandoned land, especially at mountaintop removal sites, the most destructive type of mining. As coal companies go bankrupt, this has left states concerned taxpayers may have to pick up the environmental cleanup costs. But there are also societal costs related to mountaintop removal mining’s impact on health and mental health. As an immunologist, I…

Pharmaceuticals in Drinking Water?
By Roberta Attanasio The problem of contaminated tap water in the U.S. goes well beyond Flint—and also beyond lead. There are many more toxic chemicals in our drinking water that we like to believe. Communities in New York, New Hampshire and Vermont recently found elevated levels of PFOA, a suspected carcinogen, in their water supplies. PFOA, or perfluorooctanoic acid, is a synthetic perfluoroalkyl chemical used to manufacture nonstick pan coatings and water-resistant clothing. And, even more recent is the finding that water discharged from Burlington’s wastewater treatment plant into Lake Champlain—the source of drinking water for tens of thousands of people in the Burlington area—contains concentrations of pharmaceuticals high enough to reflect…
