Figure S1. Picture of mounted iButton as carried and worn by study participants.
Figure S2. Comparison of IETs during daytime hours of the heat wave period.
Figure S3. Comparison of IETs during nighttime hours of the heat wave period.
Figure S4. Comparison of IETs between the heat wave and reference period for daytime hours
only.
Figure S5. Comparison of IETs between the heat wave and reference period for nighttime hours
only.
Figure S1. Photograph of an iButton mounted in a plastic key fob attached to a key ring
carabineer, as worn or carried by the study participants. An American penny is shown at right as
a point of comparison.
Figure S2. As shown in Figure 3 of the main text, A comparison of Individually Experienced
Temperatures (IET) and Outdoor Ambient Temperatures (OAT) in Boston’s South End during a
heat wave period, July 17-20, 2013, but for daytime hours only (12:00 to 7:00 Local Daylight
Time). Each box represents a single study participant (IET) or fixed-point monitor (OAT). The
boxes show the median (central line) and 25th and 75th percentile (edge of boxes) temperatures
and the whiskers extend to values 1.5 times the interquartile range above or below the 25th or
75th percentile. Outliers are marked with a plus sign. Fixed-point measurement abbreviations:
BSE, Boston South End; KBOS, Boston Logan International Airport. Triangles are printed above
study participant numbers where mean IETs were significant greater than (upwards-facing
triangle) or less than (downwards-facing triangle) OAT as measured in BSE.
Figure S3. As shown in Figure 3 of the main text, A comparison of Individually Experienced
Temperatures (IET) and Outdoor Ambient Temperatures (OAT) in Boston’s South End during a
heat wave period, July 17-20, 2013, but for nighttime hours only (23:00 to 6:00 Local Daylight
Time). Each box represents a single study participant (IET) or fixed-point monitor (OAT). The
boxes show the median (central line) and 25th and 75th percentile (edge of boxes) temperatures
and the whiskers extend to values 1.5 times the interquartile range above or below the 25th or
75th percentile. Outliers are marked with a plus sign. Fixed-point measurement abbreviations:

triangle) or less than (downwards-facing triangle) OAT as measured in BSE.
Figure S4. As shown in Figure 4 of the main text, the difference in mean Individually
Experienced Temperatures (IET) for each of 23 subjects in Boston’s South End (BSE) between a
heat wave period (July 17-20, 2013) and reference period (July 20-24), but for daytime hours
only (12:00 to 7:00 Local Daylight Time). Values are positive if IETs were higher during the
heat wave period and bars are shaded black if IETs between the two periods were statistically
significantly different.
Figure S5. As shown in Figure 4 of the main text, the difference in mean Individually
Experienced Temperatures (IET) for each of 23 subjects in Boston’s South End (BSE) between a
heat wave period (July 17-20, 2013) and reference period (July 20-24), but for nighttime hours
only (23:00 to 6:00 Local Daylight Time). Values are positive if IETs were higher during the
