CHAPTER III

The Effect of Humidity upon Comfort, Pulse and
Temperature

As was explained in Chapter II the subjects in our experiment
were twice a day required to write their opinion of the air con¬
dition under the headings of comfort, temperature and moisture.
The results of these comfort votes are shown in Table I.

The first column to the left of the table indicates the average rela¬
tive humidity that actually prevailed; the eight columns to the
right indicate by their approximation to 5 a condition of "just-as-
usual" comfort. Although the differences are small, they tend to
show that under moderate humidity conditions, the subjects felt
more comfortable in the drier than in the wetter condition. With
greater humidity contrast the subjects (except Squad G) felt more
comfortable under the wetter condition.

The results of the temperature votes appear in Table II.
