What is a tension headache?
Tension headaches are the most common type of headache. They are usually felt as a dull, pressing ache or a sensation of tightness around the head, often described as a band squeezing the forehead or the back of the head. Unlike migraines, they do not usually cause throbbing pain, nausea or strong sensitivity to light and sound, and most people can carry on with their day, albeit uncomfortably.
What triggers them
Despite the name, tension headaches are not always caused by muscle tension alone. A range of everyday factors can play a part:
- Stress and anxiety
- Poor posture, especially at a desk or screen
- Tiredness and disrupted sleep
- Dehydration and skipping meals
- Eye strain
- Too much caffeine, or caffeine withdrawal
Often several of these combine. Keeping a short headache diary can reveal patterns and help you spot your personal triggers.
Easing a tension headache
Most tension headaches respond well to simple measures:
- Drink water, as mild dehydration is a common contributor
- Take a break from screens and rest your eyes
- Gently stretch the neck and shoulders
- Get some fresh air or a short walk
- Try relaxation techniques or slow breathing
- Ensure you are eating regularly
Over-the-counter pain relief can help occasional headaches. A pharmacist can suggest a suitable option from our pain range, taking your health into account. It is sensible to use the lowest effective amount for the shortest time.
A word on medication-overuse headache
This point matters: taking painkillers too often for headaches can sometimes lead to a cycle of more frequent headaches, known as medication-overuse headache. This can happen when pain relief is used on many days each month over a long period. If you find yourself reaching for painkillers very regularly, speak to a pharmacist or doctor rather than simply taking more.
Preventing tension headaches
If headaches are frequent, prevention is often more effective than treating each one. Helpful habits include:
- Keeping regular sleep and meal patterns
- Staying well hydrated through the day
- Taking regular breaks from screens and checking your posture
- Building in ways to manage stress, such as exercise or relaxation
- Moderating caffeine and keeping it consistent
Regular physical activity and good neck and shoulder posture can make a real difference for people who get headaches linked to desk work.
When to see a doctor
Most tension headaches are not a cause for concern, but some symptoms need medical attention. Seek advice if:
- Headaches are becoming more frequent or severe
- They are not relieved by usual measures
- They wake you from sleep or are worse in the morning
- You are relying on painkillers on many days
Seek urgent help for a sudden, severe headache unlike any before, or a headache with fever and a stiff neck, weakness, confusion, vision changes, or one that follows a head injury. These are uncommon but important to act on.
Putting it together
Tension headaches are usually manageable with a mix of self-care, sensible use of pain relief and attention to triggers. If they are interfering with your life or changing in pattern, a clinician can help look into the cause. You can browse general products in our shop all range or visit the FAQ for ordering questions.
