Sleep & Rest
Overview
Sleep refills a colonist’s energy. Unlike Food & Eating, this need can always be met — a tired colonist who can’t find a bed will lie down on the ground rather than stay awake forever. So sleep never deadlocks your colony; it just gets slower and less pleasant the worse your accommodation is.
That’s the real decision here: not whether people sleep, but how much of their day it costs you.
How it works
A tired colonist looks for somewhere to rest in order:
- Their own assigned bed, if they have one.
- Any free unowned bed.
- A roofed room — they sleep on the floor, but sheltered.
- Wherever they’re standing.
A bed restores energy substantially faster than bare ground, which is the entire argument for building them. A colonist who beds down properly also sleeps through to genuinely rested rather than waking the moment they cross the “not tired” line — so they don’t need another nap an hour later.
Like hunger, low energy stops a colonist taking new work until they’ve dealt with it.
Playing with it
- One bed per colonist, as early as you can manage it. This is one of the highest-value early builds: it converts a slow floor-nap into a short proper rest, and gives you the day back.
- Roof the sleeping area. A roofed room is the fallback tier above bare ground, and it’s what makes an unassigned colonist’s night tolerable.
- Assign beds if you want specific colonists to always use the same one — otherwise they take whatever is free.
- If someone is sleeping on the floor next to a bed, the bed is occupied. That’s working as intended, not a pathing bug — beds hold one sleeper.
Good to know
- A tired colonist always sleeps eventually. There is no state where exhaustion has no resolution.
- Sleeping rough works, but poorly. Ground rest is deliberately slower than a bed so that furniture is worth building.
- A broken or unreachable bed downgrades gracefully — a colonist who isn’t actually recovering will give up and take the floor rather than lie there all night.
- Energy costs mood as it falls, and steeply at the bottom end. An exhausted colony is a miserable one even if it’s well fed — see Mood & Morale.
