Waking up with numbness in the back of the head may be related to physiological factors, or it may be caused by cervical spondylosis and insufficient blood supply to the brain.
1. Physiological factors: If you sleep for too long and lie down all the time, resulting in prolonged pressure on the back of the head, which affects the local blood circulation, it may cause numbness in the back of the head when you wake up.
2. Cervical spondylosis: commonly found in people with a history of cervical spondylosis, due to sleeping for a long time in an improper posture, or pillow height is not appropriate, which can easily lead to stiffness and tension of the neck muscles, the formation of local vascular compression, resulting in insufficient supply of blood to the vertebral basilar artery, which may cause numbness in the back of the head after waking up.
3. Insufficient blood supply to the brain: commonly found in patients with cerebral arteriosclerosis, due to the narrowing of the local blood vessel lumen, thickening of the blood vessel wall, resulting in slow blood flow, resulting in insufficient blood supply to the brain, oxygen supply. And sleep blood flow slowed down significantly, will aggravate the insufficient blood supply to the brain, may cause sleep woke up feeling numbness behind the brain.
After waking up with numbness in the back of the head, excluding physiological factors, you should seek medical advice as soon as possible to clarify the cause of the targeted treatment.
