Thermoregulation in hotter climates does cause an increase in heart rate, as blood flow to the skin and outer parts of the body is increased, facilitating loss of heat to the environment, and sweating occurs. However, any increase in breathing is negligible; heat does not make you "breathe more".
In relation to the thread though, increased temperatures can have a dramatic effect the physiological as well as the psychological.
