The air we breathe in our homes and offices can have a major impact on our overall health.
What Can Happen: Materials like fiberboard, foam insulation, carpets, paint, and other construction items can emit dangerous fumes called volatile organic compounds (VOCs). These can include chemicals like formaldehyde, which is known to cause respiratory issues and even cancer. They can also emit tiny particulate matter and liquid droplets that further inflame the lungs. Other particulates can be created by heating, cooking, and smoking, and can remain trapped indoors.
Why It Matters: There’s a lot of research on how climate change may affect public health, but its effects on indoor environments isn’t as well studied. As our climate changes, buildings that were designed to operate under the “old” climate conditions may not function well under “new” conditions—causing health problems for those who live, work, study, or play in them.
Climate Connection: Rising temperatures from climate change affects outdoor pollutants, creating excess smog and ozone that can find its way indoors. When combined with pollutants generated by construction and cleaning supplies, people living and working inside can experience worse air quality than people just outside their doors. Even some green buildings designed to fight climate change can also have a negative impact on indoor air because they’re built to be airtight and efficient, effectively sealing in indoor pollutants.

Home is Where the Pipeline Ends
Our study is the first to test for health-damaging air pollutants in unburned natural gas where it is used: in our homes.
New tool helps businesses, schools, evaluate indoor ventilation
The Healthy Buildings Program at Harvard T.H. Chan School of Public Health released a new online calculator to help people who are using carbon dioxide (CO2) monitors understand ventilation rates in indoor spaces and determine a maximum safe level.

Rethinking building design for the health of people and the planet
Adele Houghton, DrPH ’23, is creating new tools to help real estate teams become more responsive to the health needs of their buildings’ occupants and the surrounding communities.

Negative impacts of burning natural gas and biomass have surpassed coal generation in many states
A new inventory of air pollution impacts from stationary sources over the past decade shows this trend may continue.

COVID-19 Vaccine Acceptance Among Pregnant Women and Mothers of Young Children
As multiple effective vaccines are developed, their distribution and overall acceptance by the public is crucial to stop the spread of COVID-19. Research conducted by Principal Investigator of the Human Immunomics Initiative, Dr. Julia Wu, in collaboration with Pregistry focused on a crucial population- mothers and their children. Estimates of global vaccine acceptance among pregnant women and…
Poor indoor air quality may dull cognitive abilities
Gases such as carbon dioxide and substances released from office furniture, carpets, and desks may be dulling our minds at work, according to experts. A May 6, 2019 New York Times article catalogued recent evidence suggesting that carbon dioxide, a main ingredient in our exhalations, and volatile organic compounds (VOCs)—all commonly found in office buildings—may…

Harnessing Big Data
Medicine and public health are constantly evolving as research and technology open the doors to new ways to treat or prevent diseases. Randomized trials are the best way to assess what works. But when that’s not possible, people like Miguel Hernán, Kolokotrones Professor of Biostatistics and Epidemiology, try to replicate those trials using vast amounts…

Understanding Chronic Metabolic Diseases
The increased global incidence of chronic metabolic diseases—including obesity, diabetes, and cardiovascular and liver diseases—has become one of the greatest global health threats of the 21st century. To tackle this crisis, Murat Ülker, a leading entrepreneur in Istanbul, contributed $24 million to the Harvard Chan School in 2014 on behalf of the Ülker family to…
