What to avoid

Why be wary

No app and no device cures chronic insomnia in a few nights. Insomnia requires graded care, with CBT-I as the validated foundation.

Try instead

Look for a structured digital CBT-I programme, and see a clinician if the problem has lasted more than three months.

Why be wary

A consumer sensor can raise a flag, but it does not make a diagnosis. Only a medical test (polygraphy or polysomnography) confirms sleep apnea.

Try instead

Use a screening tool as an alert, then talk to a doctor.

Why be wary

Supplements with unclear labelling, sold alongside an app, with no visible contraindications or dosage.

Try instead

Be wary of undisclosed dosages. Melatonin is not a harmless sleeping pill; ask a pharmacist.

Why be wary

Some apps collect sensitive sleep data without a clear hosting or sharing policy.

Try instead

Check the privacy policy. Each listing states, where known, where the data is hosted.

Why be wary

No consumer monitor prevents sudden infant death. That promise is misleading and dangerous.

Try instead

Follow safe-sleep guidance: on the back, on a firm surface, nothing in the crib. Talk to a paediatrician.
