After long, uncomfortable lying or unfavorable sitting - for example, with legs crossed over one another or sitting cross-legged - it can happen that people talk about a sleepy foot or a sleepy arm. Normally, all human beings respond immediately to this symptom: they shake the affected part of the body and rub the tingling body. Usually a few minutes are enough, and the normal feeling is present again. In rare cases, it can even take up to an hour.
But where does this deaf feeling come from?
The numb feeling or furry tingling in feet, arms or hands is not related to pinched blood vessels - as has often been mistakenly assumed. Instead, it is nerve bundles that are disturbed in their conduction. Stimuli that are transmitted from the affected limbs to the brain via these nerve bundles now arrive disfigured, which leads to the feeling of discomfort.
If this phenomenon rarely occurs, it helps to check your own sitting, standing and lying habits. Do not stay in one position for too long and move from time to time. If you suffer from the symptoms described more frequently and for no apparent reason, the problem could have more serious causes (spinal acid may be involved), which you should definitely consult with a doctor.
