Headache

Headaches are one of the most common health complaints, ranging from mild and occasional to severe and disabling. Most are harmless and treatable, but certain warning signs mean a headache needs prompt medical attention.

Common types of headache

Most headaches fall into a few categories. Tension-type headaches are the most common, felt as a dull, tight band of pressure around the head, often linked to stress, poor posture or tiredness. Migraines are intense, often throbbing headaches, usually on one side, that can come with nausea, vomiting and sensitivity to light and sound. Cluster headaches are rarer but extremely painful, occurring in bouts around one eye.

These are known as primary headaches, meaning the headache itself is the problem rather than a sign of another illness. Secondary headaches are caused by an underlying condition, ranging from minor (a cold or sinus infection) to, rarely, something serious.

What causes headaches?

Everyday headaches have many common triggers, and identifying yours can help you avoid them. Frequent causes and triggers include:

  • Stress and anxiety
  • Dehydration
  • Lack of sleep or changes in sleep pattern
  • Skipping meals
  • Eye strain or screen use
  • Poor posture
  • Caffeine — too much, or withdrawal
  • Alcohol
  • Certain foods, in people prone to migraine
  • Hormonal changes, such as around periods

How to relieve a headache

Most headaches respond to simple measures. Resting in a quiet, dark room, drinking water, eating something if you have skipped a meal, and over-the-counter painkillers such as paracetamol or ibuprofen are often enough. A cool cloth on the forehead or gentle neck and shoulder stretches can ease tension headaches.

Be cautious with painkillers: taking them too often — more than two or three days a week regularly — can actually cause medication-overuse headaches, creating a cycle of daily pain. If you are reaching for painkillers frequently, see your doctor rather than taking more.

Preventing frequent headaches

If you get headaches often, prevention focuses on your triggers and overall habits. Staying well hydrated, keeping a regular sleep schedule, eating regular meals, managing stress, taking screen breaks and maintaining good posture all help. Keeping a headache diary — noting when headaches occur and what preceded them — can reveal patterns and triggers you can then address.

For migraines and other frequent or severe headaches, a doctor can offer specific treatments, including preventive medications, that go well beyond general self-care.

Types of headache explained

Understanding which type of headache you have helps you treat and prevent it more effectively, since different types respond to different approaches. The vast majority of headaches fall into a handful of recognisable patterns.

Tension-type headaches, the most common, feel like a dull, tight band of pressure around the head, usually on both sides, and are often linked to stress, poor posture or tiredness. Migraines are more intense, frequently throbbing and one-sided, and commonly come with nausea and sensitivity to light and sound. Cluster headaches are rarer but severe, striking in bouts around one eye. Sinus headaches cause pain and pressure around the cheeks, forehead and eyes, usually alongside other sinus symptoms.

Medication-overuse headaches are an important and often overlooked type: taking painkillers too frequently for headaches, more than two or three days a week regularly, can paradoxically cause a constant, daily headache. Recognising this pattern is important, because the treatment is to reduce painkiller use, ideally with medical guidance, rather than take more.

When a headache needs investigation

The overwhelming majority of headaches are primary headaches, meaning they are not caused by an underlying disease and, while unpleasant, are not dangerous. However, a small proportion are secondary headaches, caused by another condition, and certain features should prompt medical assessment to rule these out.

Headaches that are new and severe, especially the sudden 'thunderclap' headache that peaks within seconds, warrant emergency attention. So do headaches accompanied by fever and a stiff neck, by neurological symptoms such as weakness, numbness, confusion, vision loss or difficulty speaking, or those that follow a head injury. A headache that is new or different after age 50, steadily worsening over days or weeks, or waking you from sleep also deserves prompt assessment.

These warning signs are uncommon, and most headaches need only simple self-care. But knowing them means you can act quickly in the rare situation where a headache signals something more serious, while reassuring yourself about the everyday headaches that do not.

Lifestyle approaches and natural relief

Beyond treating individual headaches, many people can reduce how often they occur by addressing everyday factors. Because dehydration, hunger, poor sleep and stress are such common triggers, simple consistency helps: drinking enough water through the day, eating regular meals, keeping a steady sleep schedule, and building in ways to manage stress can all noticeably cut headache frequency.

Screen use and posture are increasingly common contributors. Taking regular breaks from screens, positioning them at eye level, and being mindful of neck and shoulder tension during long periods of desk work can ease tension-type headaches. Gentle stretching, relaxation techniques and regular physical activity also help many people, both by reducing tension and by improving sleep and mood.

For relief during a headache, resting in a quiet, dimly lit room, applying a cool cloth to the forehead or a warm compress to tense neck muscles, and staying hydrated are all simple, drug-free measures that complement painkillers. If lifestyle changes are not enough and headaches remain frequent, a doctor can help identify the type and suggest targeted treatment or prevention.

Tension Headache vs Migraine

Two of the most common headache types and how they typically differ.

Tension

Migraine

Dull, tight, band-like pressure
Intense, often throbbing pain
Both sides of the head
Often one side
No nausea
Often nausea or vomiting
Light/sound usually fine
Sensitivity to light and sound

When to see a doctor

  • A sudden, severe headache that peaks within seconds or minutes (a 'thunderclap' headache) — seek emergency care immediately
  • A headache with fever, a stiff neck, a rash, confusion, seizures, or sensitivity to light
  • A headache with weakness, numbness, difficulty speaking, or vision loss — these can signal a stroke; call emergency services
  • A headache after a head injury, or one that is steadily worsening over days or weeks
  • A new or different headache if you are over 50, pregnant, or have a weakened immune system or a history of cancer
  • Frequent headaches that disrupt your life or require painkillers several days a week

Frequently Asked Questions

Seek urgent care for a sudden severe headache, or one with fever and stiff neck, confusion, weakness, numbness, difficulty speaking, vision loss, or following a head injury. Also see a doctor for headaches that steadily worsen, are new after age 50, or frequently disrupt your life.
