Headaches are one of the most common health issues people experience, affecting millions of individuals worldwide. Globally, headache disorders impact approximately 40% of the population, ranging from a dull, nagging discomfort to intense, debilitating pain. Understanding what causes headaches is essential, as it helps identify triggers, manage symptoms, and seek timely headache treatment when needed.
While some headaches are temporary and linked to lifestyle factors, others may signal an underlying medical problem. Pain can appear at the top of the head, the base of the skull, or even on one side, and it may come with fatigue, nausea, or pressure in the head. At our Lake Jackson emergency room, we assess sudden or severe headaches especially those accompanied by concerning symptoms and provide personalized guidance for safe, effective relief based on real-world clinical experience.
Causes of Primary Headache
Primary headaches are commonly triggered by everyday habits, lifestyle factors, and natural physiological changes. Stress, sleep irregularities, diet, and sensory stimuli can all activate the brain’s pain pathways. Identifying these triggers helps in managing symptoms and preventing recurring headache episodes.
- Stress
Emotional stress, anxiety, and mental fatigue are common triggers for tension headache causes. Persistent stress can tighten muscles around the neck and scalp, leading to pain at the top of the head or base of the skull. Managing stress through relaxation techniques and mindfulness can help prevent these headaches.
- Sleep
Irregular sleep patterns, insufficient rest, or poor-quality sleep often result in insufficient sleep headaches or morning headaches. Sleep deprivation affects the brain’s pain regulation, making headaches more frequent and severe. Prioritizing consistent, restorative sleep is essential for prevention.
- Genetics
A family history of migraines can increase susceptibility. Migraines affect over 1 billion people worldwide, and genetic factors influence how the brain processes pain signals, making some individuals more prone to chronic daily headache or splitting headache. Understanding personal risk can guide early intervention and preventive strategies.
- Sensory Stimuli
Exposure to bright lights, loud noises, strong odors, or rapidly changing environments can provoke headaches. These sensory triggers may intensify migraines or barometric pressure headaches, making avoidance or protective strategies crucial.
- Poor Posture
Prolonged sitting, slouching, or hunching over screens can strain neck and shoulder muscles, triggering tension headaches. Muscle tightness may radiate to the top of the head or headache base of the skull, emphasizing the importance of proper posture and ergonomic habits.
- Diet and Hydration
Skipping meals, dehydration, or consuming processed foods can lead to hunger headaches. Fluctuating blood sugar may intensify pressure in the head or pain at the top of the head hurts. Staying hydrated and maintaining regular meals are simple yet effective preventive measures.

Causes of Secondary Headache
Secondary headaches occur due to underlying medical conditions, injuries, or external triggers rather than arising on their own. They may indicate serious health issues such as vascular problems, infections, or neurological disorders. Identifying the root cause is essential for effective headache treatment and timely intervention, helping to prevent complications and reduce the risk of recurring or severe headaches. Below are some of the most common causes of secondary headaches.
- Stroke: A stroke can cause sudden, severe headaches often accompanied by neurological symptoms like vision changes, numbness, or weakness. Immediate medical attention is crucial to prevent permanent damage.
- Brain Aneurysm: An aneurysm in the brain may trigger sudden, intense headaches due to pressure on surrounding tissues. Early detection and treatment are essential to avoid life-threatening complications.
- Concussion / Post-Concussive Symptoms: Head injuries can lead to headaches that persist for days or weeks, sometimes becoming intractable. Monitoring symptoms after trauma is important to ensure proper recovery.
- Trigeminal Neuralgia: This nerve disorder can cause sharp, stabbing headaches, sometimes described as sudden electric-like pain. Treatment often requires medical evaluation to manage symptoms effectively.
- Sinus Infections: Inflamed or infected sinuses can create facial pressure and headaches. They are also a common cause of headache and stiff neck, making proper treatment important.
- Allergies: Allergies cause headaches by inflaming sinus passages and creating pressure or congestion-related pain. Identifying specific triggers helps prevent these headaches and provides more effective symptom relief.
- Acute Glaucoma: Eye conditions such as acute glaucoma can cause sudden headaches, often with visual disturbances or eye pain. Immediate care is necessary to prevent vision loss.
- Skipped Meals / Fluctuating Blood Sugar: Irregular meals or sudden drops in blood sugar can provoke hunger headaches and intensify head pain. Consuming too much sugar can also trigger headaches by causing rapid spikes and crashes in blood sugar levels. Maintaining balanced, regular nutrition helps prevent headaches and keeps energy levels stable.
- TMJ Disorders / Jaw Muscle Tension: Tightness or dysfunction in the jaw can radiate pain to the base of the skull or back of the head. Correcting posture and addressing jaw issues often reduces headache frequency.
