The Viaggi Memory Foam Travel Neck Pillow is a versatile product that offers comfortable support for the neck during travel. While it is not designed to treat specific diseases or disorders, it can be beneficial for individuals with certain conditions:

1. Neck pain: The memory foam in the pillow conforms to the shape of the neck, providing much-needed relief to those experiencing neck pain or discomfort.

2. Cervical spondylosis: People with cervical spondylosis, a degenerative condition affecting the cervical spine, may find the pillow's ergonomic design helpful in maintaining proper neck alignment.

3. Herniated disc: For individuals with a herniated disc, the pillow's memory foam can alleviate pressure on the affected area, reducing pain and promoting better sleep.

4. Whiplash: The pillow's supportive structure can aid in stabilizing the neck and minimizing strain for those recovering from whiplash injuries.

5. Insomnia: While not a treatment for insomnia, the comfortable support provided by the pillow can improve sleep quality for some individuals, making it easier to rest during travel.

It is essential to remember that this pillow is primarily designed for travel comfort and should not be considered a substitute for medical treatment for specific diseases or disorders. Always consult a healthcare professional for individualized advice.
