🧠 Did you know?
37°C
Normal body temperature — though 36.1–37.2°C is the healthy range. "37 exactly" is a myth.
8hrs
Adults need 7–9 hours sleep. Chronic sleep deprivation raises the risk of heart disease, diabetes, and obesity.
2L
Recommended daily water intake for adults. More in heat, exercise, illness, or pregnancy.
120/80
Normal blood pressure target. Above 140/90 consistently is hypertension and increases stroke risk.
150min
Weekly moderate exercise recommended by NHS/WHO — equivalent to 30 minutes a day, 5 days a week.
6g
Maximum recommended daily salt. Most people eat double this, raising blood pressure without realising.

About & Safety

Built with safety
at its core

Prescriba is a health information assistant, not a diagnostic tool. Here is exactly what it does, how it works, and where its hard limits are.

What Prescriba is

It draws from a curated knowledge base of trusted, peer-reviewed medical sources including the NHS, Mayo Clinic, NICE guidelines, and the British National Formulary.

It is designed for the moments when you're unsure, worried, or simply want to understand your health better.
