What Is a Tension Headache?
A tension headache is a headache that produces a mild to moderate, steady ache rather than a throbbing pain. People often describe it as a band of pressure squeezing the forehead, temples, or the back of the neck. Unlike migraine, a tension headache is generally not accompanied by vomiting or severe light sensitivity, and ordinary physical activity does not usually make it much worse.
Clinicians commonly divide tension headache into two broad patterns:
- Episodic tension headache — occurs fewer than fifteen days per month. Single episodes may last from thirty minutes to several days.
- Chronic tension headache — occurs on fifteen or more days per month for at least three months. The pain may be continuous through the day.
Symptoms
The typical features of a tension headache include:
- A constant, pressing or tightening pain on both sides of the head
- Pain that feels like a tight band or cap around the skull
- Tenderness in the scalp, jaw, neck, or shoulder muscles
- Mild to moderate intensity that does not stop normal activity
- A sensation of pressure behind the eyes
Red flags that suggest something other than a simple tension headache include a sudden severe headache, headache after a head injury, fever with neck stiffness, weakness or numbness, confusion, or a headache that steadily worsens over weeks. These situations call for prompt medical assessment.
What Causes and Triggers Tension Headache?
The exact mechanism is not fully understood, but sustained contraction of muscles in the neck, scalp, and jaw, together with altered pain processing in the nervous system, is thought to play a role. Common triggers include:
- Emotional stress, anxiety, and low mood
- Poor posture, especially long hours at a desk or looking down at a screen
- Neck and shoulder strain or previous neck injury
- Eye strain and uncorrected vision problems
- Irregular sleep, fatigue, and skipped meals
- Caffeine excess or caffeine withdrawal
- Dehydration
- Overuse of pain relief medicines, which can itself cause a rebound headache
Diagnosis
There is no laboratory test or scan that confirms a tension headache. A clinician usually makes the diagnosis from the history and a physical examination, including checking the neck, jaw, and nervous system. Imaging is reserved for situations where the history or examination raises concern about another cause.
Treatment
Treatment for tension headache is usually divided into two parts: relieving an attack that is already present, and preventing future attacks. Many people need both.
Treating an Acute Episode
- Simple pain relievers such as paracetamol (acetaminophen) or non-steroidal anti-inflammatory drugs, for example ibuprofen or aspirin, taken at the recommended dose.
- Rest, hydration, and a quiet break from the activity that triggered the pain.
- Limited use — pain relief should generally be used on fewer than two days per week to avoid medication-overuse headache.
Preventive Treatment
When headaches are frequent or disabling, preventive treatment aims to reduce how often they occur:
- Medication — low doses of certain antidepressants, antiepileptic drugs, or muscle relaxants may be prescribed. These are used under medical supervision and often at doses lower than those used for other conditions.
- Relaxation training and biofeedback — structured techniques that teach a person to release muscle tension and reduce the stress response.
- Cognitive behavioural therapy — helps identify and change thought and behaviour patterns that contribute to stress and pain.
- Physical therapy — targeted exercise and manual therapy for the neck and shoulders, plus advice on posture and workstation setup.
- Regular aerobic exercise — walking, cycling, or swimming on most days of the week.
- Sleep and routine — consistent bed and wake times, regular meals, and moderating caffeine and alcohol.
Self-Care Steps That Support Treatment
- Take short, frequent breaks from screens and desk work.
- Adjust your chair, monitor, and keyboard so the neck stays neutral.
- Apply a warm compress or take a warm shower to ease tight muscles.
- Keep a headache diary recording timing, duration, triggers, and medicines used.
- Discuss any new medicine, supplement, or herbal product with a clinician before starting it.
When to Seek Medical Help
Speak with a healthcare professional if headaches are becoming more frequent, if they wake you from sleep, if they no longer respond to ordinary pain relief, or if you are taking pain medicine regularly. Seek urgent care for a sudden, severe headache, headache with fever and neck stiffness, headache after a head injury, or headache with weakness, numbness, speech difficulty, or confusion.
General information about headache disorders is available from the World Health Organization, and consumer health information is available from MedlinePlus.
Summary
A tension headache is common, often linked to stress, posture, and muscle strain, and usually responds well to simple pain relief plus lifestyle measures. When tension headache becomes frequent or chronic, preventive treatment combining medication with relaxation, behavioural, and physical approaches offers the best chance of lasting relief.
