When you wake up in the morning, your hands feel weak, your fingers feel like they are being pricked by needles, and your hands feel numb all the time. Although some people ignore it thinking it is just normal fatigue, it is actually due to problems with the nerves or blood flow to your hands. Here are the 5 main scientific reasons behind numbness and tingling in your hands:
Carpal Tunnel Syndrome (CTS): This is the most important scientific reason for numbness in your hands, especially in the thumb, index finger, and middle finger. The median nerve is an important nerve that passes through our wrist. This nerve is put under severe pressure when you use a computer mouse for a long time, do repetitive tasks like sewing, and drive a car. This is what causes severe numbness and tingling in the fingers.
Cervical Spondylosis and Disc Problems: The nerves to our hands originate from the spine in the neck. When the bones in the neck wear out (cervical spondylosis) or the disc between the bones pushes out (slipped disc), it presses hard on the nerves going to the hands. As a result, severe numbness starts from the neck and goes through the shoulders to the hands, and numbness and tingling in the fingers.
Diabetic Neuropathy: In people with chronically high blood sugar levels in the blood (Diabetes), it slowly starts to destroy the peripheral nerves in the hands and feet. This is called diabetic neuropathy. The main symptoms of this are numbness in the hands and feet, like wearing gloves and socks, and chronic tingling and numbness.
Vitamin B12 Deficiency: Vitamin B12 is an essential nutrient for the healthy functioning of nerves and the formation of the protective layer called the ‘Myelin Sheath’ around them. When its amount in the diet decreases, the nerves weaken and the extremities of the body begin to experience chronic numbness and tingling.
Poor Blood Circulation: When the hands are tucked under the body for a long time while sleeping, or when wearing tight underwear or jewelry, the blood vessels to the hands can constrict. When the cells do not receive enough oxygen-rich blood, the hands suddenly feel numb and numb (this will go away on its own after a while after resting the hand).
