You may have experienced unusual numbness and tingling of the hands, of the feet or in many other areas of the body and may have wondered what caused these conditions. Numbness and tingling may be symptoms of an underlying illness or may be a health condition on its own. A person may experience numbness of a body part when blood supply is reduced in that area. Blood supply may be depleted to the remote areas of the body due to cold temperature when blood vessels constrict, due to a clot preventing blood from moving inside the blood vessels and a high systemic blood pressure which prevents the blood from moving against an elevated pressure inside the walls of the artery. Blood may also be unable to move to a body part causing numbness when there is physical trauma, blood loss and shock. Tingling sensation on the body part may be the effect of blood loss; small nerves are reacting to oxygen depletion since blood supplies oxygen to the different tissues and organs of the body.
Acute numbness and tingling sensations can be treated right away with these measures:
Apply warm compresses on the area to facilitate blood flow.
Move the numb part vigorously by shaking or waving the part.
Numbness and tingling due to severe temperatures may be reduced by wrapping the person in warm thick blankets and taking him indoors. Let him stay near a furnace or a fireplace. You can also let his feet soak in a basin full of warm water.
Take adequate measures to improve a person’s blood pressure by medication and by elevating his head while lying down. Keep the person warm.
As the person recovers from this condition, monitor his temperature, blood pressure, respiration and pulse. If numbness and tingling of the extremities and the person’s vital signs do not improve, take him to an emergency facility right away.
Numbness and tingling of the extremities especially the hands may also be chronic in nature and may be persistent or can happen occasionally. Experts believe that lack of the B vitamins is the usual cause of this uncommon condition. If you experience chronic bouts of numbness and tingling of the hands or any part of the body, consult your doctor right away for early diagnosis and the ideal treatment.
Preventing numbness and tingling may be done by keeping to a healthy diet. Eat more high quality protein rich foods like meat, poultry, eggs, fish, sea foods and milk to improve muscle and nerve function. Eat more fruits and vegetables plus take vitamin supplements every day. Eat less fat and high cholesterol foods to keep blood pressure at a minimum. Maintain an ideal blood pressure and maintain an ideal body weight to prevent health conditions and muscle related illnesses.
Dress warmly in cold weather and take extra special care to cover hands, feet, neck and face to protect from the harsh weather. If possible avoid going outdoors, stay near a fireplace or a furnace.
