Are desk jobs dangerous for your Heart? Sedentary work and risk.

New blog post on www.DrBart.co.uk.

https://drbart.co.uk/are-desk-jobs-dangerous-for-your-heart-sedentary-work-risk/

Why this matters: the modern desk and the modern heart

Over the last 50 years, many economies moved from physically active jobs (manufacturing, agriculture) to more sedentary ones (office work, driving, computer-based work). The result: a growing portion of adults now spend much of their waking day sitting — commuting, working at desks, and relaxing in front of screens. Public-health authorities now treat prolonged sitting and low overall activity as measurable risk factors heart disease.

Sedentary lifestyle heart disease — this phrase captures the broad observational link between time spent sitting and higher incidence of coronary heart disease, stroke, heart failure, and cardiovascular death. Most prospective studies on screen time and sitting time have found that higher levels of sedentary behaviour are linked to an increased risk of both fatal and non-fatal cardiovascular disease.

Desk job cardiovascular risk — Engaging in high levels of moderate-intensity physical activity (around 60–75 minutes per day) appears to offset the increased risk of mortality linked to prolonged sitting. However, while this level of activity reduces the risks associated with extended TV viewing, it does not completely eliminate them. These findings reinforce the substantial health benefits of regular physical activity, especially in modern societies where many people spend long hours seated for work, and they may help guide future public health recommendations.

How Microplastics Might Be Silently Damaging Your Heart?

Microplastics heart disease, Microplastics and blood vessels

In recent years, micro- and nanoplastics have emerged as a growing focus of scientific and public health attention. In addition to this, in the last couple of years, multiple human studies have found plastic particles inside arterial plaque, within the walls of major blood vessels, and even in heart tissue itself. One landmark clinical study reported that people whose carotid-artery plaques contained micro/nanoplastics had a significantly higher risk of heart attack, stroke, or death over ~3 years than people whose plaque showed no plastics. That’s the first prospective signal in humans that the plastic problem may reach all the way to our cardiovascular risk.

Below, we describe what microplastics are, how they get into the body, what the best human evidence shows so far, the most plausible biological mechanisms, and what you can realistically do about exposure.

What exactly are microplastics and nanoplastics?

Microplastics are plastic fragments typically

FIVE Books 📚 that I 'read' 🎧, while Running/at the Gym in August - September 2025:

📸 Manchester, UK.

*** would recommend it
** worth reading
*you can skip it

*** 'Supercommunicators - how to unlock the secret language of connection' Charles Duhigg - fundamental principles of communication, explained through simple yet detailed rules that deepen one’s understanding of human connection.

** 'The beginning of infinity - explanations that transform the world' David Deutsch - the history of science, innovation and human evolution.

** 'The adweek copywright handbook' Jospeh Sugarman - principles of advertising and writing stories.

** 'The prince' Niccollo Machiavelli - a timeless exploration of power, deception, warfare, and manipulation, which have been shaping societies across the centuries.

* 'What we value - the neuroscience of choice and change' Emily Falk - I only wish it were more scientific, with a deeper exploration of the underlying biochemistry and physiology.

Looking for good RECOMMENDATIONs - Non Fiction please. 🙏🏻



PS. I support Arsenal, 🟥 🤙🏻.

Smart Salt? Exploring Sodium Alternatives For Better Heart Health 🫀

New blog post on www.drbart.co.uk

Take home messages:

✅ Replacing ordinary salt (sodium chloride) with potassium-enriched salt substitutes lowers blood pressure and — in large randomized trials — reduced stroke, major cardiovascular events and all-cause mortality.
https://www.nejm.org/doi/full/10.1056/NEJMoa2105675?utm

✅ A major cluster randomized trial (the SSaSS study) in China found a salt substitute (≈25% potassium chloride) reduced cardiovascular events.
https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.123.22410

✅ Much of the effect appears driven by increased potassium intake rather than sodium reduction alone. That is, potassium salt benefits extend beyond simply cutting sodium.
https://www.nature.com/articles/s41371-024-00896-4?utm_

✅ Patients with advanced kidney disease, those taking potassium-sparing medicines, or those on high-dose potassium supplements need caution — potassium excess (hyperkalemia) is the major safety concern.
https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.119.13241

✅ Global health organisations (including WHO) now support replacing regular table salt with lower-sodium, potassium-enriched alternatives as a population strategy — but implementation should include warnings for at-risk groups.
