Hormone panels generate some of the most confusing lab reports people encounter. The values are often unfamiliar, the reference ranges are wide, and the relationship between individual hormones and symptoms is rarely straightforward. A testosterone of 320 ng/dL – is that low? It depends on the lab’s reference range, the clinical context, the time of […]
Nutrition is one of the most studied and simultaneously most confused fields in science. The combination of genuinely complex research, financial interests shaping public messaging, and the internet’s ability to amplify confident misinformation has produced a landscape where myths travel faster than corrections – and often sound more convincing. Some nutrition myths are harmless. Others […]
The fitness industry is one of the most myth-saturated spaces in popular health culture. Some of these myths are harmless but waste time and effort. Others actively work against the goals of the people following them – steering people toward ineffective training, unnecessary suffering, or outright injury. Here are seven of the most persistent exercise […]
“Don’t eat after 7pm” has the status of received nutritional wisdom. It shows up in diet programs, fitness advice, and general health conversations with the confidence of an established fact. The idea seems intuitive – you eat late, you sleep, you don’t burn it off, it turns to fat. The reality is more nuanced than […]
Sleep advice is everywhere – and much of it is wrong. The myths about sleep are particularly persistent because they often feel intuitive, have been repeated for decades, and are reinforced by the same culture of productivity and performance that treats sleep deprivation as a badge of efficiency. Here are ten of the most common […]
“Immune-boosting” is one of the most commercially successful phrases in wellness marketing. It appears on supplements, teas, gummies, juices, foods, and lifestyle products. It’s also, as a concept, almost entirely meaningless – and understanding why reveals something important about how the immune system actually works and what genuinely supports it. The Problem With “Boosting” Immunity […]
When a doctor tells you your cholesterol is “fine” or recommends starting a statin, or says your blood pressure is “something to watch,” they’re making judgments based on more than a single number. They’re thinking about cardiovascular risk – the probability that you’ll have a heart attack or stroke within a defined time window, given […]
Sleep is the one health behavior that people most readily sacrifice – to work more, scroll longer, fit in one more episode, or simply because life demands it. It’s also the one health behavior with consequences that are most consistently underestimated. The research on sleep deprivation is blunt. Sleeping less than 7 hours per night […]
BMI – body mass index – is the most widely used measure of body size in medicine and public health. It’s on your medical records, it’s used to classify obesity and health risk in clinical guidelines, and it’s the basis of most large-scale epidemiological research on body weight and health. It’s also one of the […]
Most people interact with the healthcare system reactively – when something hurts, when a symptom appears, when a crisis develops. Preventive screening turns that model around. It looks for problems before symptoms develop, at a stage when intervention is most effective and damage is most reversible. The evidence for screening is not uniform across all […]
