Wellbeing tools, not medical care

Everything on this site is general information and self-guided practice for everyday wellbeing. It is not medical, psychological or professional advice. It doesn't diagnose, treat, cure or prevent any condition. Where we explain why a tool might help, we link to the research or organisation behind the claim, and we say so when the evidence is thin. Research findings are averages: they may not apply to you.

If you're worried about gaming, sleep, mood, attention, behaviour or development, for yourself or for a child, please talk to a doctor or another qualified professional.

Breathing exercises

• Breathe gently. Stop if you feel dizzy, light-headed, short of breath, or unwell, and go back to breathing normally.
• Skip the breath holds, and check with a doctor first, if you're pregnant or have a heart, lung or blood-pressure condition, a history of fainting, or a panic disorder.
• Never practise breathing exercises while driving, swimming, or anywhere a moment of dizziness could be dangerous.

Flashing and fast screens

The reaction test changes the screen colour suddenly, and the focus grid is fast and timed. A small number of people have seizures triggered by flashing lights or strong patterns, including in video games (Epilepsy Action (opens in a new tab)). If you have photosensitive epilepsy, or a history of seizures, avoid these tools or talk to your doctor first. Stop straight away if you feel unwell. Low-stimulation mode (in the Display menu at the top of each page) softens colours and removes decorative motion across the site.

Timers and alerts

Timers, warnings, sounds, vibration and notifications depend on your device and browser. Phones can mute sounds, dim the screen, or slow down pages running in the background. Treat them as helpful nudges, not as alarms. Don't use them for anything safety-critical, like timing medication.

Children

Some tools are designed to help children with routines and big feelings. They work best with an adult involved, and they don't replace a parent's or carer's judgement, or advice from a child's doctor, therapist or school. Every child is different: if a tool makes things harder, stop using it.
