Unveiling the Nighttime Agony- Why Carpal Tunnel Syndrome Feels Worse at Evening Hours

Why is Carpal Tunnel Syndrome Worse at Night?

Carpal tunnel syndrome (CTS) is a common condition that affects the wrist and hand, causing pain, numbness, and tingling. For many individuals with CTS, the symptoms tend to worsen at night, making it difficult to fall asleep or find relief. This article aims to explore why carpal tunnel syndrome is often more pronounced during the nighttime hours.

Increased Pressure on the Median Nerve

One of the primary reasons why carpal tunnel syndrome is worse at night is the increased pressure on the median nerve. During the day, when we are active and moving our hands, the carpal tunnel, a narrow passageway in the wrist, allows for some degree of movement and flexibility. However, when we sleep, our hands are often in a fixed position, leading to a higher compression of the median nerve within the carpal tunnel. This compression can exacerbate the symptoms of carpal tunnel syndrome, making them more noticeable and uncomfortable at night.

Changes in Body Position

Another factor that contributes to the worsening of carpal tunnel syndrome at night is the changes in body position. As we sleep, our hands and wrists may bend into unnatural positions, such as flexion or extension. These positions can further compress the median nerve and irritate the surrounding tissues, leading to increased pain and discomfort. Additionally, the pressure from the mattress and pillows can also contribute to the compression of the nerve, making symptoms more pronounced during sleep.

Decreased Blood Flow

Poor blood flow is another reason why carpal tunnel syndrome can be more severe at night. When we sleep, our body’s metabolism slows down, and blood flow to various parts of the body, including the hands and wrists, may decrease. This reduced blood flow can lead to a lack of oxygen and nutrients reaching the affected tissues, causing pain and swelling to worsen. As a result, individuals with carpal tunnel syndrome may experience increased symptoms during the nighttime hours when blood flow is at its lowest.

Increased Sensitivity to Pain

Lastly, the body’s sensitivity to pain can also contribute to the worsening of carpal tunnel syndrome at night. During sleep, our brain is more susceptible to pain signals, making us more aware of the discomfort caused by carpal tunnel syndrome. This heightened sensitivity can amplify the symptoms, making them feel more intense and disruptive to sleep.

In conclusion, carpal tunnel syndrome is often worse at night due to increased pressure on the median nerve, changes in body position, decreased blood flow, and increased sensitivity to pain. Understanding these factors can help individuals with CTS manage their symptoms more effectively and seek appropriate treatment to alleviate nighttime discomfort.
