When you're in a cool room, you produce more saliva than when you're in a warm room.
Scientific Claim
Salivary flow rate increases during cool air exposure (20°C) compared to normothermic conditions (28°C) in healthy young males, with mean salivary flow rates of 723 ± 256 µL/min in cool conditions versus 592 ± 196 µL/min in normothermic conditions.
Original Statement
“Compared with PL-Norm (592 ± 196 µL·min−1), mean SFR was higher in BR-Norm (697 ± 246 µL·min−1; P = 0.02, dz = 0.54), PL-Cool (723 ± 256 µL·min−1; P = 0.02, dz = 0.67), and BR-Cool (758 ± 261 µL·min−1; P = 0.01, dz = 0.85)”
