Caffeine leaves the body gradually rather than all at once. This tool estimates how much of what you drink today may still be active at bedtime, and suggests a window for finishing your last caffeinated drink. It is a planning estimate, not medical advice, and it cannot tell you how you personally respond.

A fifteen-minute wind-down sequence in three five-minute parts: close the day, lower stimulation, prepare for rest. Includes a shorter version for evenings that end too late.

A ten-minute audit of the room you sleep in — light, noise, temperature and comfort — to find the one thing worth fixing first. Most of what it finds costs nothing.

Why the fix for a bad night often belongs in the morning. A simple daylight-and-wake-time routine, including the smallest version that still works on a dark, rushed morning.

The shortest useful starting point. How sleep works in plain terms, the four things that shape it, and one change you can make in the next hour — free, no purchase needed.

Sleep does not begin at bedtime. A practical guide to caffeine, meals, movement and the daytime habits that decide how the night goes — what to move, when, and why.

A seven-day plan to find out what is actually affecting your sleep. One change per day across timing, daylight, your bedroom and your evenings — then a written plan built from whichever ones worked for you.

A practical guide to the room you sleep in: light, noise, temperature, mattress, pillows and bedding — including what is genuinely worth buying and what is not.

A 21-day plan for making sleep changes stick: stabilise what already works, adapt it to real life, then handle the weekends, stress and disruptions that normally undo it.

A practical guide to ending the day properly. Mental unloading, lowering stimulation, and a wind-down sequence built around your actual evenings rather than an ideal one.

A guided 30-day journal for noticing your own sleep patterns: what helps, what gets in the way, and what is worth trying next. Observation rather than another programme to follow.

A practical guide to your body clock: wake time, morning light, finding your sleep window, and holding a schedule together through weekends, shift changes and travel.
