Awesomedlviewer health: sleep, eyes and back at the screen

An independent reference on healthy screen habits. It is not medical advice and is not connected with the former site on this domain; we do not distribute videos.

Sources and limitations

This page explains where the specific information in this reference comes from, why there is not much of it and why a lot is described in general terms. We deliberately rely on a small set of recognised sources and don't fill the gaps with guesswork.

We can't see how you sleep, how well you see or what hurts. So we talk about habits, and leave your health to you and your doctor.

— Editor's note

How we choose sources

The specific figures in this reference come from World Health Organization guidelines: those on children under 5 from the 2019 document, and those on physical activity and time spent sitting from the 2020 document. The 20-20-20 rule is given as described in guidance from ophthalmology associations.

If there is no reliable source on a question, we do not invent figures or retell individual studies. Instead, we describe a general habit and suggest discussing the details with a doctor.

Main sources

  • World Health Organization: 2019 guidelines on physical activity, sedentary behaviour and sleep for children under 5 years of age
  • World Health Organization: 2020 guidelines on physical activity and sedentary behaviour
  • Ophthalmology associations: guidance on eye strain when using screens

Limitations of this reference

Awesomedl is neither a medical organisation nor a streaming service. We do not diagnose; we do not recommend medicines, eye-care products, supplements or glasses; and we do not advertise clinics, devices or services.

The advice here is intended for healthy adults and children and describes habits, not treatment. If you have an eye condition, sleep problems, back pain or questions about your child's development, your doctor is your main point of reference.

We also do not name programmes, series, services or devices: this is a reference about viewing habits, not about what to watch or where. If you notice an inaccuracy or outdated advice, check it against the original source and with your doctor; they are what really counts.
