What is normal blood pressure – the evidence

 
This guide is based on scientific evidence, following our policy for evidence-based guides.

It’s written by Anne Mullens with the latest major update on July 22, 2019. Additional editing and fact-checking by Dr. Andreas Eenfeldt, MD. The guide was medically reviewed by Dr. Bret Scher, MD, on July 19, 2019.

The guide contains scientific references. You can find these in the notes throughout the text, and click the links to read the peer-reviewed scientific papers. When appropriate we include a grading of the strength of the evidence, with a link to our policy on this. Our evidence-based guides are updated at least once per year to reflect and reference the latest science on the topic.

All our evidence-based health guides are written or reviewed by medical doctors who are experts on the topic. To stay unbiased we show no ads, sell no products and take no money from industry.1 We’re fully funded by the people, via an optional membership.2
