Chronic headaches that begin as a dull ache behind the eyes and escalate into relentless pain may signal underlying health issues. Addressing these causes effectively can provide lasting relief, according to Harley Street GP Dr Kaywaan Khan, who warns against simply attributing headaches to stress.
Dr Khan, founder of Hannah London, identifies six common but often overlooked headache triggers beyond stress and dehydration, explaining how to recognize them and take steps toward relief.
- Poor Sleep Quality
Disrupted sleep is a major contributor to headache development. If you wake with headaches accompanied by loud snoring, dry mouth, or daytime fatigue, your sleep patterns may be problematic. Adults need seven to nine hours of uninterrupted rest for optimal brain function. To improve sleep quality and reduce headaches, maintain consistent bedtimes, avoid caffeine late in the day, and limit evening alcohol consumption.

Digital Eye Strain
Extended screen time can cause ‘digital headaches’ characterized by dry, sore eyes and blurred vision. These headaches usually worsen as the day progresses and feel like tightness around the temples and forehead. Dr Khan recommends the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds to relax eye muscles. Using a warm towel over closed eyes during breaks can also reduce eye strain. Adjust screen brightness to suit ambient light and consult an optometrist if symptoms persist.
-
Medication Overuse
Paradoxically, frequent use of headache medications—including common painkillers and prescription triptans—can trigger rebound headaches. This cycle occurs when pain relief wears off, prompting increased medication intake and worsening headaches. Keeping a headache diary can help track medication use and facilitate meaningful discussions with your GP.
-
Sinus and Nasal Issues
Chronic sinus inflammation, infections, allergies, or structural abnormalities like polyps and deviated septa can cause persistent headaches. Symptoms often include congestion, reduced sense of smell, and postnasal drip. These issues can also disrupt sleep, intensifying headaches. Treatment options include saline nasal rinses, allergy management, and staying hydrated. Persistent or severe cases should be evaluated by a GP or ENT specialist.
-
Migraines
Migraines are a neurological disorder frequently mistaken for stress-induced headaches. They may cause sensations of sinus pressure, ongoing discomfort, and episodic intense flare-ups, sometimes preceded by visual or sensory auras. Common triggers include hormonal changes, blood pressure fluctuations, and smoking. Affecting about one in seven people in the UK, migraines can be managed through lifestyle changes, preventive medications, and acute treatments. Botox injections have also emerged as a promising option for reducing migraine frequency and severity. Early and proper management is crucial to prevent migraines from becoming more frequent and disabling.
-
Allergies
Histamine release during allergic reactions can provoke headaches and migraines. Nasal congestion linked to allergies may also reduce appetite and hydration, worsening headache symptoms. Testing for allergies and receiving appropriate treatment can significantly alleviate these headaches.
By recognizing these often overlooked causes, individuals can take targeted steps toward effective and long-lasting headache relief. Consulting with healthcare professionals remains essential for accurate diagnosis and tailored treatment strategies.
