Objective:

The objectives of this study are 1) to quantify the relationship between indoor and outdoor temperature and humidity and the built environment; 2) find actionable thresholds linking indoor temperature, humidity, and the built environment to extreme heat (summer) and influenza like illness (winter) distress calls; and 3) project future health risk related to climatic, demographic, and built environment changes.

Progress Summary:

There is limited evidence directly linking indoor heat exposure to health outcomes. By partnering with Emergency Medical Services, our first publication (Uejio, et al., 2016) observed indoor conditions of people receiving emergency care. The results suggest people may suffer from hot indoor environments even during “moderate” summer periods.

The second publication (Tamerius, et al., 2017) is the first study to estimate temperature and humidity conditions during tropical influenza transmission in a real-world environment. We showed evidence of influenza transmission in extreme temperature and humidity conditions. For example, during one transmission period, temperatures exceeded 39ºC, and specific and relative humidity reached 22 g/kg and 85%, respectively.

The third publication (Jung and Uejio, 2017) studies how people use social media to discuss extreme heat and air conditioning. In Los Angeles, New York, and Atlanta, people talked about extreme heat and air conditioning more during hotter compared to cooler than normal periods.

The fourth study (Uejio, et al., 2018) investigated the heat exposure of workers who work outdoors or indoor locations without air conditioning. The study found that everyday heat exposures continuously challenge the health of outdoor worker. Many participants experienced hotter and more humid conditions than the local weather station.

Future Activities:

We will include analyses of the relationship between the indoor data and outdoor weather data as well as the relationship between the indoor conditions and emergency calls. We will also statistically relate patient demographics to data from the Census ACS. We will continue data analysis and manuscript writing into Fall/Winter 2018 and 2019
