Positional Headaches
On this article you will find

Positional Headache is a type of headache that is associated with changes in head position.

This means that the headache occurs or worsens when you change your head position, such as standing up, bending over, or lying down.

The pain is typically felt in the back of the head and neck.

Positional headaches often occur due to changes in cerebrospinal fluid (CSF) pressure.

Cerebrospinal fluid is a clear, colorless fluid that surrounds and cushions the brain and spinal cord.

It provides buoyancy and support to the central nervous system.

When there is a decrease in CSF pressure, it can lead to a positional headache.

A mystery?

Positional headaches can be considered mysterious or challenging for several reasons:

Varied Causes

Positional headaches can result from various underlying causes, making it challenging to pinpoint a specific reason in each case.

The primary cause is often related to changes in cerebrospinal fluid (CSF) pressure, but the source of the pressure change can vary.

Spontaneous Occurrence

In some cases, positional headaches can occur spontaneously without an apparent cause or trigger.

This makes it difficult to predict when and why these headaches may develop.

Subtle CSF Leaks

Cerebrospinal fluid leaks, which are a common cause of positional headaches, can be subtle and challenging to detect.

Locating the exact site of the leak may require specialized imaging techniques or procedures.

Overlap with Other Headache Types

Positional headaches can share symptoms with other types of headaches, such as migraines or tension-type headaches.

This overlap can complicate the diagnosis and contribute to the mystery surrounding the condition.

Individual Variability

People may experience positional headaches differently, and the factors contributing to these headaches can vary widely among individuals.

This variability makes it challenging to establish a one-size-fits-all explanation.

Limited Understanding

Despite advances in medical knowledge, there is still much to learn about the intricacies of CSF dynamics, especially in relation to headaches.

Ongoing research aims to improve our understanding of the underlying mechanisms and potential contributing factors.


Positional headaches are often associated with changes in cerebrospinal fluid (CSF) pressure, and the underlying causes can vary.

Here are some common causes of positional headaches:

CSF Leak

A leak in the cerebrospinal fluid (CSF) is one of the most frequent causes of positional headaches.

CSF leakage can occur spontaneously or as a result of medical procedures like lumbar punctures, spinal surgeries, or epidural anesthesia.

When there is a loss of CSF, the pressure around the brain and spinal cord decreases.

Changes in head position, such as standing up or bending over, can further affect CSF dynamics and lead to a headache.

Diagnosis may involve imaging studies (MRI or CT myelogram) to identify the location of the leak.

Spontaneous Intracranial Hypotension (SIH)

SIH is a condition characterized by low CSF pressure within the skull without an obvious cause.

It often leads to positional headaches.

The cause of SIH is not always clear, but it is thought to involve spontaneous CSF leaks.

When the pressure is reduced, the brain sags within the skull, causing headaches, especially when changing positions.


Inadequate fluid intake can lead to dehydration, and dehydration is a potential cause of headaches.

Dehydration can reduce the volume of CSF, impacting its ability to cushion and support the brain. Changes in head position may exacerbate this effect.


Migraines are a type of headache characterized by severe pain, often accompanied by other symptoms like nausea and sensitivity to light and sound.

While migraines are not exclusively positional, changes in head position can trigger or worsen migraines in some individuals.

Diagnosis is based on the characteristic symptoms, medical history, and exclusion of other potential causes.

Tension-type Headaches

Tension-type headaches are a common type of headache characterized by mild to moderate pain and pressure.

These headaches may be exacerbated by changes in head position, possibly due to muscle tension in the neck and shoulders.

Diagnosis is based on the nature and pattern of headaches, medical history, and exclusion of other causes.

Orthostatic Hypotension

Orthostatic hypotension refers to a sudden drop in blood pressure upon standing.

Changes in blood pressure can affect cerebral perfusion, leading to headaches, especially when standing up.


Positional headaches themselves are not typically associated with serious complications.

However, the underlying causes of positional headaches may lead to complications if left untreated.

Here are potential complications related to some of the common causes of positional headaches:

Complications of CSF Leak

Infection: If a CSF leak is present, there is a risk of infection entering the central nervous system, leading to conditions such as meningitis.

Complications of Spontaneous Intracranial Hypotension (SIH)

Subdural Hematoma: In some cases, SIH can lead to the development of subdural hematomas (accumulation of blood between the layers of the protective covering of the brain), especially if the condition is not promptly diagnosed and treated.

Complications of Dehydration

Electrolyte Imbalances: Severe dehydration can lead to electrolyte imbalances, affecting the normal functioning of cells and organs in the body.

Complications of Migraines
Chronic Migraine: Frequent or severe migraines can lead to the development of chronic migraine, a condition characterized by headaches on 15 or more days per month.

Complications of Tension-type Headaches

Decreased Quality of Life: Chronic tension-type headaches can significantly impact a person’s quality of life, affecting daily activities and overall well-being.

Complications of Orthostatic Hypotension

Falls and Injuries: Sudden drops in blood pressure, especially when standing up, can increase the risk of falls and injuries.

5 Powerful Solutions

Although Positional Headache could cause discomfort, it can be managed.

Here are 5 powerful solutions:


Maintaining proper hydration is crucial in preventing and alleviating positional headaches.

Dehydration can reduce the volume of cerebrospinal fluid (CSF), impacting its ability to cushion and support the brain.

When changing head positions, especially from lying down to standing up, dehydration can exacerbate the drop in CSF pressure, leading to headaches.

Individuals should ensure an adequate intake of fluids throughout the day, particularly in situations where dehydration may be more likely, such as during physical activity or in hot weather.

Monitoring urine color and frequency can be useful indicators of hydration status.

Bed Rest and Postural Changes

For those experiencing headaches associated with changes in head position, especially in the context of cerebrospinal fluid leaks or spontaneous intracranial hypotension, bed rest and specific postural changes may be recommended.

Maintaining a horizontal position can help reduce the gravitational effects on CSF pressure, potentially alleviating positional headaches.

However, these measures should be implemented under the guidance of a healthcare professional, as excessive bed rest can have its own set of complications.

Caffeine Consumption

Caffeine, found in coffee, tea, and some over-the-counter medications, can have vasoconstrictive effects and may help alleviate headaches.

In some cases, moderate caffeine intake can be considered as part of a headache management strategy.

However, it’s important not to overconsume caffeine, as excessive intake can lead to rebound headaches and other side effects.

Individuals should discuss caffeine use with their healthcare provider, taking into account individual health conditions and sensitivities.

Physical Therapy and Neck Exercises

Tension-type headaches, which may be exacerbated by changes in head position, can benefit from physical therapy and specific neck exercises.

Physical therapists can provide guidance on stretching and strengthening exercises to reduce muscle tension in the neck and shoulders.

Improved muscle flexibility and strength can contribute to better posture and decreased likelihood of headaches triggered by certain head positions.

Individuals should consult with a healthcare professional before starting any exercise program to ensure it is safe and tailored to their specific needs.


Depending on the underlying cause of positional headaches, medications may be prescribed to manage symptoms.

Pain relievers, such as nonsteroidal anti-inflammatory drugs (NSAIDs), may help alleviate headache pain.

For individuals with spontaneous intracranial hypotension or other specific conditions, medications such as caffeine, theophylline, or epidural blood patches may be recommended.

It’s essential to follow the healthcare provider’s guidance regarding the appropriate use of medications, as overuse or misuse can lead to complications.

Individuals experiencing positional headaches should seek prompt medical attention for a thorough evaluation and diagnosis.

The choice of treatment will depend on the specific cause identified by healthcare professionals, and a tailored approach is essential for effective headache management.

Additionally, individuals with persistent positional headaches should be cautious about certain activities that may exacerbate their symptoms, such as sudden changes in head position.

Adjustments to daily activities and postures may be recommended to minimize discomfort and reduce the risk of complications.


Preventing positional headaches often involves addressing underlying causes and making lifestyle adjustments.

Here are some precautions that can help prevent positional headaches:

Stay Hydrated

Ensure adequate fluid intake to prevent dehydration, as dehydration can contribute to changes in cerebrospinal fluid (CSF) volume and pressure.

Drink water regularly throughout the day, especially in situations that can lead to increased fluid loss, such as hot weather or physical activity.

Maintain Proper Posture

Practice good posture to reduce strain on the neck and shoulders, which can contribute to tension-type headaches.

When sitting or standing, keep the spine aligned, and avoid prolonged periods of bending over or looking down.

Ergonomic adjustments in workstations can also help maintain proper posture.

Gradual Changes in Position

When transitioning from lying down to standing up, or vice versa, do so gradually.

Sudden changes in position, especially from a horizontal to a vertical posture, can affect blood pressure and cerebrospinal fluid dynamics, potentially triggering headaches.

Take a moment to sit upright before standing.

Cautious Use of Caffeine

If caffeine is part of your routine, use it judiciously. Moderate caffeine intake may have vasoconstrictive effects that can help alleviate headaches.

However, excessive caffeine consumption can lead to rebound headaches and other side effects.

Discuss caffeine use with your healthcare provider, and be mindful of its potential impact on your headaches.

Regular Exercise and Neck Stretches

Engage in regular physical activity to promote overall health and well-being.

Include exercises that focus on neck strength and flexibility to reduce muscle tension.

Physical therapy and specific neck stretches can be beneficial, especially for tension-type headaches.

Proper Sleep Position

Ensure that your sleeping environment and position support good sleep hygiene.

Use a comfortable mattress and pillow that provide adequate support for the head and neck.

Experiment with different sleeping positions to find the one that minimizes strain on your neck and head.

Manage Stress

Stress can contribute to tension-type headaches.

Implement stress management techniques such as deep breathing, meditation, yoga, or other relaxation exercises.

Identify and address sources of stress in your life, and seek support when needed.

Regular Health Checkups

Attend regular health checkups and communicate any recurring headaches or changes in headache patterns to your healthcare provider.

Early detection and intervention can help prevent complications associated with certain underlying causes of positional headaches.

Avoid Excessive Bed Rest

While bed rest may be recommended in specific cases, excessive and prolonged bed rest can have negative consequences, such as muscle atrophy and joint stiffness.

Follow healthcare provider recommendations regarding rest and activity levels.

Seek Prompt Medical Attention

If you experience persistent or severe positional headaches, seek prompt medical attention.

A healthcare professional can conduct a thorough evaluation, including imaging studies, if necessary, to identify the underlying cause and recommend appropriate treatment.
