Finnish Meteorological Institute experts conducted a survey about the thermal perception of children during their participation in a summer camp week in 2018. The study showed that children could express themselves in thermal comfort surveys.

Thermal sensation studies with children are scarce due to difficulties to interview children and find suitable thermal conditions to carry out the survey (Rupp et al., 2015). As a part of the Horizon 2020 iSCAPE project (Improving the Smart Control of Air Pollution in Europe) (iSCAPE–project, 2018) living lab activities were embedded into summer activities aimed for children within the Science Camp of the Finnish Science Centre Heureka (HEUREKA, 2018).

A total of about 700 children taking part in the Camp were organized to groups based on their age; from 7 to 13 and from 14 to 16 years, respectively. For the younger children, there was every day of the week up to four different activities related to various fields of science, including also meteorology and climate. The FMI iSCAPE team assisted in designing this activity.

Furthermore, for the children at the age from 13 to 16 years, a unique program was organized in three weeks during the Camp.

During the summer camp, there was a period (31.7.–2.8.2018) with high daily air temperature, fair wind and clear sky conditions. This period was suitable to survey the children’s thermal sensations on consecutive days to find out if there are changes in thermal sensation between the hot days.

The structure of the survey was simple; only one question was asked: How did you experience the outdoor air temperature this morning on your way to the Camp? The answer was given by touching on a poll pad to a 5-step scale from 1 (red smiley = really uncomfortable) to 5 (green smiley = very comfortable). Up to 99 children participated in the survey. The percentage of collected answers lay between 85 and 90%. The results are presented in Fig. 1.

FIG 1: Results of the 3-day Heureka summer camp survey on thermal
sensation, 31.7.–2.8.2018.

The share of uncomfortable thermal sensation increased during the study period together with increasing temperature. The change from day one to day three was statistically significant with p-value = 0.04 (Chi-squared-test).
