Servers running React, Next.js, or using tools like Datadog are vulnerable to a new Denial of Service attack (patched on January 13th). If you're processing user data, like we are, then your server could be at risk. Thankfully HDA isn't using server side rendering, and is not affected. Do check if you are.. What's the risk? Someone can force your server to crash by making it process malicious data. How is it triggered? Someone sends your server a JSON object with e.g. 50k la

Here's what to look for when choosing a health data app.

There’s a structural limitation most users (and many developers) misunderstand: LLMs don’t reliably “read everything” you give them, especially when the input is long, messy, or spread across multiple files.

Why does longevity tracking only work when you can track your health trends and baselines over time? Biohackers and longevity-focused users generate more health data than almost anyone else: Wearables track sleep, HRV, activity, and recovery Continuous glucose monitors measure metabolic responses Blood tests reveal inflammation, hormones, lipids, and micronutrients Notes, protocols, supplements, and experiments live somewhere else entirely Yet most people trying to optimise h

This week’s React Server Components vulnerability (a critical pre-auth RCE) turned a lot of internet-facing apps into soft targets overnight. We saw malicious activity hit an analytics-facing entry point, so we did what you hope you never need to do:

The structural limitation of EHRs is that they are designed to document what happens within a health service, not around or beyond it. The most important evolution of care would mean stitching together the full, textured picture of a person’s health journey: clinical events, yes, but also the patterns, behaviours, and experiences that influence risk, compliance, resilience and recovery. This requires a shift in both mindset and infrastructure.

At HDA, we are convinced: having a clear stance on user data from A to Z is non‑negotiable. Security has to be built into every layer.

Health Data Avatar guarantees security and privacy of your health and personal data, How does HDA actually achieve that? We'll try to explain you our data privacy & security in metaphors.

Why managing labs, clinics, wearables and apps in one place is the future of healthcare Centralising all your health data isn’t a luxury; it’s a necessity. Today , your health data lives everywhere and belongs to anyone but you, its rightful owner. Blood test results sit in lab portals, discharge summaries live in hospital systems, GP letters hide in PDFs or physical letters, wearables track sleep, heart rate and activity, but there's not much you can do with this data. Diff

Health data fragmentation is costing people time, clarity, care and lives. Interoperability alone won’t solve it. Why health data fragmentation is the real problem, and why patients must be at the centre to centralise health data. Health data is broken, and the cost for both patients and governments is huge Health data is supposed to support care. Instead, it's one of the biggest barriers that costs patients and public healthcare money, time, clarity, continuity, nerves, trus
