The Five Minute Workday can be corrected with time pressure in the form of quest timers and/or wandering monsters.
Heck, in my group, we normally get a wandering monster check (from a D4 to a D10 check) any time we stop to do a 10-minute ritual spell. Sucks for us - over half of our encounters are normally random encounter monsters.
Also, in one campaign, we get a level of exhaustion if we sleep in medium-heavy armor; therefore we have to take off armor to sleep. Nothing better than being a fighter with AC 11 or 12 and expected to hold the center of the line. I've had more encounters where I've almost died coming out of a slumber to fight than staged encounters.
IF I can find a master armorer, there is a rumor we (I) could get fitted plate armor which means you can sleep in it and the wearing encumbrance weight would be reduced in half. Honestly that would be better for my character than +2 plate. Sigh....
