If Your Hands & Feet Are Always Falling Asleep, You Might Have 1 Of These 6 Health Issues

There probably isn't a human being alive who isn't familiar with odd sensation of a hand or foot or limb falling asleep. That tingly, slightly numb feeling is annoying, to be sure, and can definitely derail you for a minute or two, but it's usually just the result of something completely innocent. In some cases, though, frequent pins and needles can be a sign of something more serious. In fact, if your hands and feet are always falling asleep, you might have one of several health issues.

"The most common reason for temporary numbness of the feet is postural habits that put pressure on the nerves and reduce blood flow to the lower extremities," Dr. Miguel Cunha, Founder of Gotham Footcare and a leading podiatrist in Manhattan, tells Romper.

"Certain habits can cause temporary sensation of pins and needles in the feet because of positions that may include crossing the legs for too long, or sitting or kneeling for long periods of time, such as sitting on the toilet for too long," Dr. Cunha continues, adding that wearing tight shoes or clothes can also cause temporary numbness. However, that uncomfortable sensation isn't always something you can shrug off.

"There also underlying diseases that can contribute to more long-term or more frequent episodes of numbness and tingling sensations," Dr. Cunha adds, "ranging from conditions such as sciatica pain from a herniated disc, Morton’s neuroma, or diabetic peripheral neuropathy."

As WebMD explained, peripheral neuropathy has a wide range of causes, from traumatic or repetitive stress injuries to infections to systemic diseases and even exposure to toxins. That's why it's important to get yourself checked out by a doctor if you find your hands and feet falling asleep on a regular basis. As WebMD put it, "The earlier the underlying cause of your tingling is identified and brought under control, the less likely you are to suffer potentially lifelong consequences." Hopefully it's NBD, but if there is something troubling going on (like one of the conditions below), you'll want to start treating and managing it sooner rather than later.

Ranging from pins and needles in the feet and legs to problems with the digestive system, urinary tract, blood vessels, and heart, diabetic neuropathy is a type of nerve damage that can occur if you have diabetes, according to the Mayo Clinic.

That's because "high blood sugar (glucose) can injure nerves throughout your body," though the condition's progress can be slowed through blood sugar control and a healthy lifestyle. Peripheral neuropathy starting in the feet and legs (followed by the hands and arms) is the most common type of diabetic neuropathy, and symptoms include numbness, tingling, burning, and a reduced ability to feel pain or temperature changes (or, conversely, an increased sensitivity to pain).


Vitamin Deficiency

Not only is vitamin B12 deficiency common in the U.S., but a "clear link has been established between a lack of vitamin B12 and peripheral neuropathy," as the Foundation for Peripheral Neuropathy explained on its website:

"A lack of B12 damages the myelin sheath that surrounds and protect nerves. Without this protection, nerves cease to function properly and conditions such as peripheral neuropathy occur." Even relatively mild B12 deficiency can adversely affect the nervous system and the proper functioning of the brain, and this nerve damage can become "permanently debilitating" if the underlying condition is not recognized and treated.


Autoimmune Diseases


Autoimmune diseases such as Sjogren’s syndrome, lupus, and rheumatoid arthritis cause the immune system to attack the body’s own tissues, which can in turn lead to nerve damage, according to the National Institute of Neurological Disorders and Stroke:

"When the tissue surrounding nerves becomes inflamed, the inflammation can spread directly into nerve fibers. Over time, these chronic autoimmune conditions can destroy joints, organs, and connective tissues, making nerve fibers more vulnerable to compression injuries and entrapment."


Cancer Being Treated With Chemo

Neuropathy is a common side effect of some medications, according to the Foundation for Peripheral Neuropathy, particularly drugs used to treat cancer (known as chemo-induced PN):

"In some people, these medications may cause nerve damage that results in a loss of sensation or movement in part of the body." The good news is, peripheral neuropathy will usually go away if these drugs are changed or discontinued, or if the dose is reduced (though it can take anywhere from a few weeks to a few months for symptoms to subside.



A variety of both viral and bacterial infections and infectious diseases can also lead to nerve damage. The Mayo Clinic listed the following as potential causes of neuropathy: Lyme disease, shingles, Epstein-Barr virus, hepatitis C, leprosy, diphtheria, and HIV (medicines used to treat HIV can also lead to temporary nerve damage, like chemo).


Hereditary Diseases


Sometimes, a hereditary condition is the cause for ongoing pins and needles, according to the Center for Peripheral Neuropathy. Charcot-Marie Tooth Disease, for example, is a progressive degeneration of the muscles in the foot, lower leg, hand, and forearm, while Hereditary Neuropathy with Liability to Pressure Palsies is a "hereditary disorder in which a fairly mild pressure or trauma to a single nerve" can result in episodes or periods of weakness and numbness. Also known to cause peripheral neuropathy is Ehlers-Danlos Syndrome, a rare genetic disorder of the connective tissue which has multiple neurological manifestations, and Multiple Sclerosis, a disease of the brain and spinal cord thought to be caused by a combination of genetic and environmental factors.

Remember, chances are you don't have anything to worry about, except that maybe you have a tendency to stay in the same position for too long. But if your extremities seem extremely sleepy on a regular basis, it can't hurt to get it checked out just in case.
