At least once in your life you must have asked yourself why do your hands go to sleep and if this is something normal or is a reflection of a situation that you must attend to.
The condition for which your hands feel numb is called paresthesia and consists of the loss of sensation and ability to move for a short period of time.
Sometimes paresthesia is accompanied by a sensation of itching, burning, or even painful stitches in the fingertips and palms of the hands.
It generally occurs because we have fallen asleep or are resting for a long time in a position in which we apply weight or pressure on the hands or forearms or any other part of the body.
This pressure limits the flow of blood to this area and causes stress on the nerves, which when we get up or change position, «wake up» generating pangs and all kinds of uncomfortable sensations.
But if this happens to you very frequently, you should look for a specialist who will tell you the reason for why do your hands go to sleepas there may be something going on with your body that needs immediate attention.
But why do your hands go to sleep?
Most of the cases of numb hands it relates to having slept in a position where you apply weight to them.
When the weight or pressure is removed, the hand initially feels numb and has little tactile sensitivity.
As blood circulation in this area normalizes, the nerves begin to «reactivate», which is accompanied by a feeling of stinging, like pinpricks, that lasts only a few minutes.
However, if it happens very regularly or the discomfort always lasts longer than 10 minutes, you should consider the possibility that you suffer from chronic paresthesia.
This is a condition that indicates the possible presence of an injury to the nerves of the hand or upper extremities or a neurological disorder.
Phases of paresthesia and the problem of numb hands
So that you better understand the why do your hands go to sleep We are going to tell you that in 1946 scientists from the University of Oxford determined the different phases of paresthesia.
The first stage is called «compression tingling» and can appear 3 to 4 minutes after you start applying pressure to the hand.
If we continue to apply pressure to the limb, after 10 minutes the second stage of paresthesia will begin, called «soft numbness», in which a loss of sensation and tingling will occur.
The third phase of paresthesia occurs when pressure is released and is called «pin prick release.»
Once the muscles and nerves receive blood flow again they «wake up» causing the sensation of receiving numerous needle sticks.
In any case, if the numbness of hands occurs very frequently you should go to a specialist to rule out that you suffer a condition called chronic paresthesia.
Migraine and neurological problems, the first cause of hand numbness
Now we are going to delve into the list of complications that can explain why your hands go to sleep.
Migraine is one of the main ones and 15% of those who suffer from this problem also complain of a feeling of numbness in the face, while 13% they complain about hands numb, arms or legs.
The pain can be so severe that the person feels unable to move the affected limb.
Other cause of adorrocking hands is the scarpal tunnel syndrome, an inflammation of the tendons that pass through the carpal canal, pressing on the nerves and causing pain, tingling and numbness in the hands.
According to many studies, a nutritional deficiency can increase the frequency of paresthesia, especially in the female sex. If this is your case, do not forget to take the 10 best vitamins for women.
This syndrome occurs in people who perform repetitive activities for many hours a day, such as writers, secretaries, and computer scientists.
Finally we have cerebrovascular accidents (CVA) or strokes, which are perhaps the most dangerous possible reason for why do your hands go to sleep.
They are often accompanied by neurological problems such as loss of speech, vision, confusion, and headaches, requiring urgent medical attention.
Artery problems and other complications
Some diseases of the circulatory system reduce blood flow to the extremities, favoring the appearance of paresthesia.
For this reason, doctors emphasize the importance of maintaining good health and avoiding habits that can hurt your heart.
If you suffer from multiple sclerosis this will explain why do your hands go to sleep or you feel constant tingling in them, as a result of progressive damage to the nerves and brain cells.
Other cause of hand numbness is diabetic neuropathy, in which the high level of glucose in the blood for a long time causes damage to the nerves.
This can lead to symptoms such as paresthesia in the hands, pain in the legs, and burning on the soles of the feet.
In fact, almost the half of diabetic patients develop some type of neuropathy.
We also have epicondylitis or tennis elbow, a condition similar to carpal tunnel syndrome in which inflammation of the tendon that joins the elbow with the forearm presses on the nerves of the hand.
Finally, another cause of why do your hands go to sleep It may be cervical osteochondrosis, a degenerative inflammation of the spine at the level of the cervical vertebrae that compresses the nerves that communicate with the superior nerves.
This in turn causes a disruption of blood flow, tingling in the hands, headache, and loss of coordination.
