Types of Headaches: What the Primary and Secondary Split Means for Diagnosis
The types of headaches doctors recognize fall into two groups: primary, where the headache is the disorder, and secondary, where it signals something else.
Health and fitness you can act on — nutrition, exercise, conditions and wellbeing, explained clearly and grounded in what the evidence supports.
Health information has a trust problem, and it earned it. Between the miracle headlines, the supplement marketing and the advice that reverses every few years, a reasonable person could conclude that nobody knows anything. The truth is quieter: a great deal is known, it changes more slowly than the headlines suggest, and most of it points toward unglamorous fundamentals. This section is built on that quieter truth.
The coverage spans nutrition, exercise, sleep, stress and the conditions that touch most lives. Nutrition articles explain what foods and nutrients actually do, where the evidence is strong, where it is thin, and why the boring advice about vegetables and protein keeps surviving every diet trend that promised to replace it. Fitness guides cover strength, cardio, mobility and recovery for real schedules and real starting points, on the principle that the routine you keep beats the routine you quit.
Condition explainers describe symptoms, causes and standard treatments in plain language, so a diagnosis, your own or a family member's, stops being a wall of jargon. Articles on everyday complaints, sleep trouble, back pain, colds and their remedies, focus on what genuinely helps versus what merely sells. Mental wellbeing is treated as health, full stop, with the same evidence-first approach.
One boundary is held everywhere: this section informs decisions and never replaces the person qualified to make them with you. Anything touching diagnosis, medication or treatment ends at the same door, talk to your doctor, because a writer who has never met you should not be finishing that sentence. What the articles can do is send you into that conversation with better questions.
The featured guides above gather our most complete coverage of a topic in one place, and the grid below runs newest first. Start where your actual life is, sleep, food, movement, or the condition you just heard named, and build from there.
