Do the restrictions[1] apply prior to washing upon awakening from a day time sleep?
No. The restrictions that apply before washing after awakening from a night sleep do not apply when one slept during the day.[2] Nevertheless some[3] are meticulous to prepare water near their bed, when they sleep for 60 breaths, even during the day.
[1] Such as walking four Amos, touching food and clothing etc.

The Reason: As according to the Arizal the spirit of impurity does not reside during the day and it is only due to respect of the Beis Yosef that we require one to wash. However there is no need to be more stringent than even the Beis Yosef himself. [Ashel Avraham ibid]
Implication from Admur: From fact that Admur only writes that it is “proper” to wash, and not that it’s an obligation, shows that certainly regarding the restrictions one may be lenient.
