Protect it the way you'd protect a meeting
Unstructured time dies in households because it looks available. If you're the person everyone addresses questions to, say the thing out loud: "I'm having half an hour, I'll be back at four." Not "I'm just going to lie down for a bit," which invites negotiation. Partners and older children adapt faster than you'd expect when the boundary is specific rather than apologetic.
And resist the urge to make it productive retroactively. If the half hour produces nothing but a slightly clearer head, it worked. If you find that no amount of rest touches the exhaustion — that you're flat for weeks rather than tired for days — that's worth raising with a doctor rather than solving with a better routine.
Why do I feel guilty when I rest?
Usually because rest has been bundled with worth: we learned that being useful is how you earn your place, so idleness feels like a debt accruing. Noticing the guilt without obeying it is the whole skill — you can feel the twinge and stay in the chair anyway, and the twinge gets quieter each time it isn't rewarded with activity.
How long before doing nothing stops feeling restless?
Most people report that the physical fidget settles within the first session, but the mental itch — the sense that you should be achieving something — takes a few weeks of regular small doses to fade. Keep the sessions short and frequent rather than long and heroic; twenty minutes four times a week rebuilds the capacity far better than one abandoned spa afternoon.
