General information only
Everything written on this site is published for general information. It does not take account of your circumstances, health, equipment or ingredients, and it is no substitute for advice from a qualified professional who knows your situation. Liability for relying on it is limited as set out in the terms and conditions.
Health, fitness and exercise
Pages covering HIIT, Tabata, interval training, rest between sets, yoga, breathing and sleep describe widely used protocols and cite published research. They are not medical advice and not a training programme prescribed for you.
High-intensity exercise carries real risk. Before starting or significantly changing an exercise routine — particularly if you are new to hard exercise, pregnant, recovering from injury or illness, over 40, or living with a heart, lung, joint or blood-pressure condition — speak to a doctor or a qualified instructor.
Stop immediately if you feel chest pain, dizziness, faintness or unusual shortness of breath. Breathing exercises should never be forced; if you feel light-headed, return to normal breathing.
Sleep
Nap lengths quoted here come from published research on alertness. They describe averages across studied groups, not what will happen to you. Persistent tiredness, insomnia or daytime sleepiness are worth raising with a doctor rather than managing with a timer.
Cooking and food safety
Cooking times on this site are conventional guides. Actual results depend on your hob or oven, altitude, pan, quantity and the size and starting temperature of the food. Ovens commonly run well off their dial.
Timing alone does not make food safe. Judge doneness by the signs described and, for meat, poultry, fish and eggs, follow the food safety guidance of your national food authority — including internal temperatures. If you are pregnant, elderly, very young or immunocompromised, follow the stricter advice that applies to you, particularly regarding soft-boiled eggs.
Examinations and formal timing
The exam and classroom timers are practice and teaching aids. For a formal, graded or accredited examination, use the timing method your examination board or institution requires. Do not use a browser tab as the official clock for an assessment that matters.
Timer accuracy
The countdown is measured against your device's own clock and is accurate to a fraction of a second in normal use. However, browser behaviour, background-tab throttling, battery-saving modes, muted tabs, silent switches and operating-system restrictions can all affect whether an alarm is heard, or whether the page keeps running.
Do not use this site for safety-critical timing, medication schedules, medical procedures, laboratory or industrial processes.
Research and sources
Where a figure comes from a published study, that study is cited at the foot of the page with journal, volume and page numbers so you can check it. Citing research is not a claim that its findings apply to you, and a single study is not settled science. Where a widely repeated figure comes with an important caveat, we state the caveat alongside it.
External links
Links to other sites are provided so you can verify sources. We are not responsible for their content or accuracy, and a link is not an endorsement.
