Understanding Hearing and Hearing Loss
Hearing is a vital sensory system that connects us to the world and plays a key role in communication. Hearing loss may occur at birth or be acquired later in life. Early identification by an Audiologist, Neonatologist, Otolaryngologist, Parents, and Nurses enables timely management, reduces the functional impact of hearing loss, and supports the development or preservation of communication skills.
Hearing loss in adults and older individuals may or may not be accompanied by tinnitus, balance difficulties, and challenges with auditory processing. Individuals with hearing loss may have associated issues such as anxiety, stress, increased listening effort, and various psychosocial concerns.
Hearing Loss and Its Causes
- Hearing is essential for communication and social interaction. According to the WHO, over 360 million people worldwide live with disabling hearing loss, most of whom are adults.
- Common contributors include genetic, noise exposure, ototoxic medications, chemical exposure, and age-related changes such as presbycusis. These factors can be exacerbated by lifestyle factors such as stress and inadequate health management.
- Hearing loss typically presents as conductive, sensorineural, or mixed types. Central auditory processing disorders are also being identified more frequently in recent years.
- Additional contributing causative factors include circulatory problems, metabolic disorders, and other systemic health conditions.
Management of Hearing Loss
- Audiologists perform comprehensive evaluations, often in collaboration with medical professionals, to determine the degree and type of hearing loss.
- Conditions affecting the outer or middle ear are commonly treated through medical or surgical intervention.
- Disorders involving the inner ear, auditory nerve, or central auditory pathways are usually managed through hearing aids, cochlear implants, implantable devices, assistive listening technologies, and various compensatory strategies.
A Holistic Approach to Hearing Wellness
- When hearing, vestibular, and associated psychosocial disorders cannot be fully resolved through hearing amplification devices, medical or surgical means, a holistic, multifactorial approach is recommended. This may include lifestyle modifications, dietary improvements, and supportive practices such as yoga.
- The Gharanda Samhita and Hathayoga Pradipika texts describe the development of asana (postures) and pranayama (breath control) to create a strong and healthy body.
- Ancient texts also describe the practice of focusing on the breath (pranayama) to calm the mind and reduce stress.
- Yoga was seen as a way to enhance mental health, physical strength, prosperity, promote well-being, and help prevent disease. It is viewed as a way to achieve unity between the mind and body, a holistic approach to health and well-being.
Yoga Practices that can support hearing health
- Specific yoga asanas and breathing techniques are proposed to support hearing health:
- Greeva Chalan: Neck exercises to enhance blood supply to the brain and inner ear.
- Skandh Chalan: Shoulder rotations to improve circulation and relieve tension.
- Bhramari Pranayama: A breathing exercise that produces a humming sound, stimulating the inner ear and potentially aiding in tinnitus relief.
- Kumbhak: A breath-holding technique that increases carbon dioxide levels, promoting vasodilation and improved blood flow to the cochlea.
Additional Techniques and Practices
- Shankha Naad: Blowing a conch shell is suggested to stimulate the inner ear and improve respiratory function.
- Mudras: Specific hand gestures like Shunya Mudra and Gyan Mudra are recommended for enhancing hearing acuity and cognitive function.
- Dietary Recommendations: Emphasis on foods rich in omega-3 fatty acids, antioxidants, and vitamins to support hearing health and prevent age-related decline.
Conclusion
- A comprehensive approach combining medical, surgical, yoga, lifestyle changes, dietary adjustments, and awareness of environmental factors is a holistic approach for preventing and managing hearing and vestibular disorders.
- With the aging population, proactive measures are crucial to mitigate the impending increase in hearing impairment and risk of falls globally.
