Many people, especially representatives of the older age groups, are familiar with the sensation of tingling, "creeping", awkwardness, numbness in the hands, especially at night. However, the symptom can occur at any age. The main and most common reason why hands go numb at night is cervical osteochondrosis or salt deposition in the cervical spine. This disease occurs in 70% of the population over the age of 50, but the process begins after overcoming the 30-year milestone. Now more and more often you can find osteochondrosis in adolescents.
Among other causes of discomfort in the hands, there are diseases of the heart and circulatory system, atherosclerosis, atherothrombosis of blood vessels, diabetes mellitus, hypertension, polyarthritis of small joints, inflammation in the nerves themselves, a lack of B vitamins.In the absence of any pathology, numbness in the hands may occur with an incorrectly selected pillow or an unphysiological position of the body and, above all, of the hands, during sleep. Many have a habit of sleeping with their arms thrown up or under their heads, which impedes blood circulation in the upper extremities.
How hands go numb at night
Unpleasant sensations can be very diverse in their localization. It is very rare to see numbness of the entire arm. More often, some part of it becomes numb, which depends entirely on the cause of the disease:
1. Cervical osteochondrosis, spondylosis, hernia or protrusion of the intervertebral discs of the cervical spine, especially when the pathological process is localized in the lower cervical segments (C5-C7). It is from this part of the spinal cord that the nerves go to the hands. Moreover, depending on the affected nerve root, numbness can be localized:
along the inner surface of the hand, from the shoulder to the tips of the 5th and half of the 4 fingers of the hand (C7);
on the back of the shoulder and forearm, back of the 2 and 3 fingers (C6);
along the side of the hand to the thumb and forefinger (C5).
With a common pathological process of the lower cervical region, the location of the numbness may be different. Headache with cervical osteochondrosis is also not uncommon.
2. Carpal tunnel syndrome - compression of the nerves going to the hand in a narrow canal formed by the bones of the wrist. It occurs during prolonged activity associated with the same type of load on the hands by the type of flexion-extension movements (working at the computer, playing musical instruments, assembling parts, conveyor belt). In this case, numbness of the entire hand or its parts is observed strictly below the wrist, sometimes numbness of the fingers is observed. The overlying parts of the hand are not involved in the pathological process.
3. Polyarthritis of small joints of the hand. It is characterized by the presence of manifestations only in the fingers.
4. In case of pathology of the shoulder or elbow joints, symptoms will occur in the lower parts of the upper limb.
5. Diabetes mellitus and other metabolic disorders (liver disease, kidney disease, endocrine pathology). This also includes the abuse of alcohol and nicotine, since the mechanism of development of pathology is very similar. Numbness in this case has an "ascending" character, begins with more distant sections and gradually, over time, "rises" up. This happens as the larger vessels are involved. Two hands are usually affected at once, the sensations are symmetrical.
6. In case of hypertension, muteness of the hands at night appears only with an increased level of blood pressure.
7. Hand numbness in heart disease is of particular importance. Here you should pay attention to which hand is going numb. If unpleasant sensations occur in the right hand, this can be attributed with a high percentage of probability to cervical osteochondrosis. But numbness in the left arm can be a sign of serious heart problems, such as angina pectoris or heart attack. If the numbness of the left hand occurs suddenly, especially at night, and does not go away within an hour, it is imperative to see a doctor.
What to do if hands go numb in a dream
1. Try to eliminate all possible factors:
replace the pillow;
choose a more comfortable sleeping position, often changing position in order to prevent the vessels from being pinched;
exclude the use of alcohol and nicotine, especially at night;
do not engage in work before going to bed that involves stress on the hands.
2. Exercises for numbness of the hands at night:
without getting out of bed, lie on your back and stretch your arms up, bend and unbend your fingers 50 times, then put your hands along the body and repeat the exercise;
rotational movements in the wrists;
stand up and close your hands behind your back in the lock, try to raise them as high as possible;
in mild cases, just shake your hands.
3. You can relax tense cervical muscles with light self-massage before going to bed and during the day. It is enough just to rub your neck with your palms, while you can use anti-inflammatory ointments (nise, fastum gel).
4. In the absence of contraindications and depending on the reason, physiotherapeutic procedures can be used:
phonophoresis, darsonvalization of hands;
paraffin wax on the hands, forearms;
electrophoresis with lidase on the area of the carpal canal.
5. Folk remedies:
honey compress: spread honey on the numb areas of the hands with a thin layer, wrap and leave overnight, a course of 7-10 procedures;
Marsh rosemary: 5 tbsp Pour 1 cup of apple cider vinegar with crushed raw materials, insist for a week and use for rubbing numb areas;
a glass of hot water every morning on an empty stomach will help strengthen the walls of blood vessels.
