Tingling in Hands and Fingers When Sleeping – What Is It?

Tingling in Hands and Fingers

Some people are awoken in the night by tingling in hands and fingers. In many cases, this can be attributed to a less than relaxed sleeping position, where the person is either lying on the hands or they are elevated in an awkward fashion. This can even occur if the hands happen to fall over the edge of the bed, where the hand circulation is impacted by the forces of gravity, and the blood pumped throughout is forced to face a perilous journey in an attempt to get back to the heart. For these common causes of hand circulation issues resulting from positions that a sleeping person may inadvertently find themselves in overnight, the causes of tingling in hands and fingers are evident and not concerning. But, there are other causes of the sensation that may prove to be a bit more alarming than simply position induced poor circulation. And, sufferers encountering the feelings regularly, or in conjunction with other present symptoms may need a medical evaluation to determine the source.

Conditions related to bad circulation can certainly be a cause of tingling in hands and fingers overnight. There are many conditions that can contribute to a decrease in blood flow and therefore, the sensation of tingling in hands and fingers. However, one that is very common is Raynaud’s phenomenon. This condition is characterized by the narrowing of blood vessels in response to certain stimuli or, in the case of the syndrome variant of the condition, in response to an underlying health condition like lupus. Because of the narrowing of the blood carrying, vessels, which are less able to transport oxygen rich blood throughout the body similarly to the effects observed in persons with clogged arteries, it is not uncommon for numbness and tingling to present as a result of bad circulation from the condition. In some cases, pain may be present as well along with color changes to the affected areas, with fingers and hands turning almost blue.

Another condition that can cause tingling in hands and fingers is peripheral neuropathy. This particular ailment is related to the damage of nerves that affect various functions of the body. The disease impacts the nerves that control motor function, and can result in coordination challenges. And, this same effect can also cause problems with muscle control where spasms and cramps as well as problems with the bladder and bowels as a result of the underlying nerve damage can occur. Nerves that feel sensation are impacted as well in neuropathy, and this can contribute to a loss of sensation entirely in certain areas, as well as promote the feelings of tingling and numbness too. In small fiber neuropathy sensation can be impacted so much that even gentle touch can feel painful to sufferers. And, circulation is also impacted in peripheral neuropathy where the nerves that are responsible for contracting and relaxing the blood carrying vessels are affected, leading potentially to tingling in hands and fingers as well as other extremity locations as a result of poor blood circulation.

There are more common causes of tingling in hands and fingers that may be related to the everyday activity of the nighttime sufferer. Carpal tunnel syndrome, a hazard of occupations involving repetitive actions of the hands, can lead to bouts of tingling and numbness and even pain, as the inflammation associated with the condition worsens. eHow.com explains that in persons with fibromyalgia, carpal tunnel can exacerbate the symptoms of tingling and numbness.

Unfortunately, there are both sinister and common culprits behind nighttime tingling in hands and fingers. Serious diseases such as HIV can be a factor, as well as other conditions like diabetes and syphilis. This is why it is incredibly important to monitor symptoms as they present. Medical evaluation can reveal whether or not a health concern is playing a role in the development or worsening of pain or tingling in the extremities. And, if the symptoms get worse or are accompanied by other symptoms such as confusion, a decrease in motor skill function or others, it is even more important to consult with a health care provider. While many cases of tingling in hands and feet while sleeping can be very easily explained by a less than ideal sleeping position resulting in poor circulation in hands, there are many more potential causes that should be considered if the situation is not explainable by position, is worsening or accompanied by other symptoms. And, in these cases, medical advice should be employed.
