Articles on heart health, blood pressure, cholesterol, and the quiet signs of cardiovascular ageing , written for curious readers who want to understand what's going on inside.
A 2026 NHANES analysis of 14,012 adults found finishing the last meal before 9pm was linked to slower biological ageing in heart, liver, and body. Strongest after 40.
A 3.8-million-person meta-analysis shows exercise intensity predicts mortality more reliably than total duration. Here's what the data means for how you train.
Tennis added 9.7 years of life expectancy in the Copenhagen City Heart Study. Jogging added 3.2. Here's what the data shows, and what probably explains the gap.
Men using a sauna four to seven times a week had a 77% lower risk of dying from cardiovascular disease. The data, the mechanism, and who should be cautious.
Eleven extra minutes of sleep, four and a half more minutes of activity, a small diet improvement. New UK Biobank data shows how much that shift cuts cardiovascular risk.
The evidence that light drinking is protective has mostly fallen apart. Two large 2022 and 2023 analyses show measurable harm at levels most people consider moderate.
The news doesn't end. Your stress system doesn't know the threat isn't in the room. The line from continuous anxiety to heart and brain damage is direct.
Chronic loneliness measurably lowers vagal tone, weakens vaccine response, and raises stroke and heart attack risk. It's a cardiovascular problem.
The problem with cortisol usually isn't the level. It's the rhythm. A flat daily curve nearly doubles cardiovascular mortality risk in large-cohort data.
Adding load to walking produces a predictable jump in metabolic cost, stimulates bone formation, and loads the heart harder. Without the joint impact of running.
BMI is a crude tool. Where your fat sits matters more than the total. A 300,000-person meta-analysis shows waist-to-height ratio outperforms BMI for cardiometabolic risk.
Visceral fat is metabolically dangerous and resistant to calorie restriction. The interventions that move it most: muscle, post-meal walks, and protein adequacy.
Cardiorespiratory fitness predicts mortality more reliably than smoking, diabetes, or hypertension. The data, and how much you can actually move it.
