Why can’t I hear when I first wake up?

Waking up in the morning is typically associated with a sense of rejuvenation and alertness. However, for some individuals, the experience is quite the opposite. Upon waking up, they may notice a sudden hearing loss or difficulty in hearing. This phenomenon, known as sudden sensorineural hearing loss (SSHL), can be alarming and raise numerous questions. In this article, we will explore the reasons behind why you may experience hearing loss when you first wake up and delve into the possible causes, mechanisms, and management of this condition.

Understanding Sudden Hearing Loss

Sudden sensorineural hearing loss refers to the rapid onset of hearing loss that typically affects only one ear. It occurs due to a malfunction in the sensory organs of the inner ear, which are responsible for detecting sound and transmitting signals to the brain. While the exact cause of SSHL is not always known, certain triggers and underlying conditions have been associated with its onset.

Causes of Sudden Hearing Loss

The malfunction of the sensory organs within the inner ear is the primary cause of sudden hearing loss. However, there can be various triggers or underlying conditions that may contribute to its occurrence. Some possible causes include:

1. Inner ear sensory organ malfunction: Dysfunction of the delicate structure of the inner ear, such as the hair cells or cochlea, can disrupt the normal hearing process and result in sudden hearing loss.

2. Potential triggers or underlying conditions: Several factors, such as viral infections, autoimmune disorders, certain medications, and circulatory issues, have been linked to sudden sensorineural hearing loss.

Mechanisms of Hearing Loss upon Waking Up

Many individuals notice their hearing loss specifically upon waking up in the morning. Several mechanisms can contribute to this phenomenon:

1. Impact of changes in inner ear pressure during sleep: Throughout the night, the pressure within the inner ear can fluctuate due to changes in body position and the relaxation of muscles. These pressure changes can potentially affect the function of the sensory organs and lead to temporary hearing impairment.

2. Role of reduced blood flow to the ear during sleep: During sleep, blood flow to various parts of the body, including the ears, can decrease. Insufficient blood supply to the inner ear can compromise its function and result in hearing loss upon waking up.

Other Factors Contributing to Temporary Hearing Loss upon Waking Up

In addition to the mechanisms mentioned above, there are other factors that can contribute to temporary hearing loss when you first wake up:

1. Accumulation of earwax during sleep: Earwax, or cerumen, naturally accumulates in the ear canal as a protective mechanism. However, excessive earwax buildup can block the passage of sound waves and lead to temporary hearing impairment.

2. Temporary fluid buildup in the ear: Fluid accumulation in the middle ear, such as from congestion due to allergies or a cold, can cause hearing difficulties. This buildup is often more noticeable in the morning when gravity has been working to drain the fluid throughout the night.

Symptoms and Characteristics of Sudden Hearing Loss upon Waking Up

Sudden sensorineural hearing loss upon waking up often presents with specific symptoms and characteristics:

1. Unilateral hearing loss: The most common presentation of SSHL is hearing loss in only one ear. This unilateral nature distinguishes it from other forms of hearing impairment.

2. Difficulty in using the affected ear, such as on the phone: Individuals with sudden hearing loss may notice difficulty using the affected ear, especially during activities such as phone conversations. This is due to the impaired transmission of sound signals to the brain.

Diagnosis and Treatment Options

If you experience sudden hearing loss upon waking up, it is important to seek medical evaluation and examination. An ear, nose, and throat specialist, also known as an otolaryngologist, can help determine the underlying cause and provide appropriate treatment options. The diagnostic process may involve:

1. Medical evaluation and examination: The healthcare provider will assess your medical history, perform a physical examination, and ask about your symptoms to understand the potential causes of your sudden hearing loss.

2. Potential tests and imaging techniques: Further tests, such as audiometry (hearing tests), tympanometry (middle ear evaluation), and imaging techniques like MRI or CT scans, may be conducted to assess the severity and identify any structural abnormalities or underlying conditions.

3. Treatment options: The treatment approach for sudden hearing loss can vary depending on the underlying cause and individual circumstances. It may include corticosteroids to reduce inflammation and improve hearing, antiviral medications if a viral infection is suspected, or other therapies such as hyperbaric oxygen therapy or hearing aids.

Prevention and Management of Sudden Hearing Loss upon Waking Up

While sudden hearing loss cannot always be prevented, there are steps you can take to potentially minimize the risk or manage the condition:

1. Regular ear hygiene and cleaning: Maintain proper ear hygiene by gently cleaning the outer ear with a cloth. Avoid using cotton swabs or other objects that can push earwax deeper into the ear canal.

2. Regular check-ups: Schedule regular check-ups with an otolaryngologist to monitor your ear health and identify any early signs of hearing loss.

3. Adopting good sleep habits: Establish a consistent sleep routine and ensure a comfortable sleep environment to minimize sleep-related triggers that may contribute to sudden hearing loss.


Experiencing sudden hearing loss when you first wake up can be unsettling and raise concerns about your overall ear health. While the exact cause may vary from person to person, sudden sensorineural hearing loss often occurs due to a malfunction in the inner ear’s sensory organs. Understanding the mechanisms, symptoms, and treatment options can help you navigate through this condition and seek appropriate medical care. By adopting good ear hygiene practices and regular check-ups, you can take preventive measures and potentially mitigate the risk of sudden hearing loss upon waking up.
