Identify your headache
Before looking for the cause, it is important to identify the symptoms. The most common forms are:
- Tension headache: Often feels like a tight band pressing around the forehead or the back of the head. It is usually linked to stress, muscle tension, or lack of sleep.
- Migraine: An intense, throbbing pain that often sits on one side of the head. It is frequently accompanied by sensitivity to light, sensitivity to sound, and nausea. These attacks occur as distinct episodes lasting between 4 - 72 hours.
- Cluster headache: A rarer but extremely painful form where the pain is concentrated around one eye. It is sometimes called "suicide headache" due to its intensity.
Important to remember: Many people worry about serious illnesses like brain tumor when their head aches. However, it is important to know that this is a very rare cause of headaches. Most often, the explanation lies in lifestyle or biological imbalances.
What is your body saying? Underlying biological causes
When headaches become recurring, it is wise to look beneath the surface. Through blood analysis, patterns can often be identified that explain the pain:
Fluid and electrolyte balance
The body needs a precise balance of salts for the nervous system to function optimally. A deficiency in magnesium can lead to muscles and vessels contracting, while an imbalance in sodium affects the fluid pressure in the brain.
Anemia
If you often feel dizzy and tired in addition to your headache, iron deficiency may be the culprit. When the blood cannot transport enough oxygen to the brain, the body often responds with a dull, aching pain.
Hormonal fluctuations
Hormones such as estrogen and progesterone have a major impact on the body's pain threshold. Many women experience "hormonal headaches" in connection with menstruation or menopause. Thyroid hormones (TSH, T4, T3) can also cause chronic fatigue and pain when imbalanced.
Blood sugar
Significant fluctuations in blood sugar, so-called "sugar crashes," are a common trigger. If the body struggles to keep sugar levels stable, it can result in a persistent headache that often arises a few hours after a meal.
Lifestyle – the invisible trigger
In addition to purely biological factors, everyday life plays a major role:
- Stress and cortisol: Long-term stress keeps cortisol levels high, which causes shoulders and the neck to pull upwards – a direct ticket to tension headaches.
- "Tech neck" and screen time: Static strain in front of the computer and blue light strain both the eyes and neck musculature.
- Diet and caffeine: Skipping coffee one morning can cause severe withdrawal headaches, while certain foods can trigger migraines in sensitive individuals.
When is it time to act?
Most cases of headaches are harmless, but your body is an expert at signaling when something is not right. You should consider getting tested or seeking medical care if:
- The pain suddenly changes character or becomes significantly stronger than before.
- The headache is combined with extreme fatigue, dizziness, or heart palpitations.
- You need to take over-the-counter painkillers several times a week.
