How to use the online timer
Sleep here competes with a long evening. The outdoors is only pleasant after dark for months at a time, social life runs late, and bedtime slides without anyone deciding it should. The one thing that works in the other direction is that the clocks never move, so a routine chosen in one season still means exactly the same thing six months later.
These pages cover the parts of it a timer can genuinely help with: a half-hour wind-down between the end of the evening and lights out, a nap short enough not to leave you worse off, an evening routine for a household with children, and a lying-down session at the end of the day for anyone whose head is still running through tomorrow at eleven at night.
Consistency of timing tends to matter more than total hours, and the weekend is where most of it is lost. None of this is medical advice and none of it replaces it — persistent trouble sleeping is worth raising with a doctor rather than solving with a routine. But a fixed wind-down, kept most nights, is a reasonable place to start.
