How often has it occurred that you experienced numbness in your hands immediately after waking up? One of the most common reasons for this is sleeping on one arm for too long. However, if the numbness is repeated continuously every day, there may be an underlying cause or a chronic condition behind it.
Common reasons for waking up with numb hands
1. Diabetes
If your blood sugar levels are high, there are chances of a possible damage to the blood vessels that circulate blood to peripheral parts of the body. Shortage of oxygen in the blood can also lead to nerve damage that causes numbness. But this numbness is first experienced on the feet and then on the hands.
2. Sleeping in a bad posture
When you sleep in a bad posture or sleep resting on one arm for too long, it creates excess pressure on the arm. This pressure compresses the nerves in that area and causes numbness.
3. Toxins and Medications
Medical treatment like chemotherapy or medicines used to treat conditions like heart ailments or blood pressure can result in peripheral neuropathy. Being exposed to toxins in insecticides or other toxins such as mercury, arsenic and lead can damage nerve cells.
4. Deficiency of Vitamin B12
Vitamin B12 performs the function of nerve signal transmission in the body. People who are deficient in Vitamin B12 and Vitamin B6 will often experience numbness in arms and legs.
5. Injury or an insect bite
An injured nerve around the neck area can make you feel numbness in hands. Also, toxins in seafood, animal or insect bites can contribute to numbness in hands.
6. Alcohol abuse
Consuming alcohol in excessive amounts can cause numbness in hands. Alcohol adversely impacts the nervous system. Alcohol abuse for a long period of time can cause permanent damage to nerve cells.
7. Other diseases
7. Other diseases
Other health conditions like rheumatoid arthritis, HIV/AIDS, syphilis, stroke, multiple sclerosis and lupus can cause peripheral neuropathy.
