Environmental temperature can affect respiration. For example, in hot weather, your body may breathe faster to help cool you down. Excitement or anxiety increases the respiratory rate as well. This is part of the body’s response to stress, where it prepares for increased activity. Generally, larger individuals may have a slower respiratory rate because they have a larger lung capacity.
