Sleep
Sleep and the working week
Most sleep loss in adults is scheduled rather than pathological, and the fixes are structural rather than medical.
Sleep
Insomnia, timing, shift work and what actually helps.
Sleep
Getting to sleep when your mind will not stop
The techniques that work operate by occupying cognitive resources rather than by relaxing you, which is a useful distinction.
Sleep
Waking at three in the morning
Middle-of-the-night waking has specific causes and a specific set of unhelpful responses, most of which people do automatically.
Sleep
What sleep trackers can and cannot tell you
They are reasonably good at one thing, unreliable at another, and capable of causing a specific problem of their own.
Sleep
Sleep across a lifetime
Requirements and architecture change with age in predictable ways, and much of what is treated as decline is normal.
Sleep
Dreams, nightmares and things that happen in the night
Sleepwalking, night terrors and vivid nightmares have distinct mechanisms, and one of them is a warning sign.
Sleep
Snoring and sleep apnoea
Most snoring is harmless and some of it is a sign of a condition that is common, serious and substantially undiagnosed.
Sleep
The bedroom itself
Temperature, light and noise have measurable effects on sleep architecture, and most bedrooms get at least one badly wrong.
Sleep
Sleep and alcohol
It is the most widely used sleep aid in the world and one of the least effective, for reasons that are well characterised.
Sleep
Napping, properly
Length and timing determine whether a nap restores you or wrecks the night, and the difference is well characterised.
Sleep
Body clocks, light and why you wake at the wrong time
Chronotype is largely biological, and the mismatch between it and working hours has a name and consequences.
Sleep
Insomnia, and why sleep hygiene rarely fixes it
The standard advice is not wrong, it is simply not a treatment — and there is a treatment.
