Nonlethal damage.

[Lord Pendragon]

Unless things have changed in 3.5, nonlethal damage stacks with lethal damage when determining when a character falls unconscious. Also, whenever a PC is healed 1 point of lethal damage through magical healing, he's also healed 1 point of nonlethal damage.

My question is: does nonlethal damage heal naturally, during a day filled with strenuous activity, i.e. adventuring? And if so, at what rate?

 

[Starglim]

You heal nonlethal damage at the rate of 1 hit point per hour per character level.

(PHB p. 146) Makes no reference to strenuous activity, nor to rest. It would probably be sensible that you don't heal nonlethal damage if you did something for the whole hour that caused you further nonlethal damage, such as forced marching or swimming.

Thanks Starglim.
