Introduction
Lying flat and feeling a sensation of head fullness or congestion may be caused by physiological reasons, or by conditions such as cervical spondylosis or hypertension. Treatment—whether general management or medication—should be based on the specific underlying cause. Besides these common causes, it could also result from tension headaches, cerebral infarction, or cerebral vascular hardening. It is recommended to seek timely medical attention if discomfort occurs.

Lying flat and feeling a sensation of head fullness or congestion may be caused by physiological factors, or it could result from medical conditions such as cervical spondylosis or hypertension. Treatment—whether general management or medication—should be based on the specific underlying cause. The details are as follows:

I. Physiological Causes

If one has recently been staying up late frequently and suffering from sleep deprivation, this can easily affect the nervous system and lead to symptoms such as dizziness and a feeling of pressure or pain in the head. These symptoms usually improve with adequate rest.

II. Pathological Causes

1. Cervical Spondylosis

Cervical spondylosis is typically caused by degenerative changes in the cervical spine. Prolonged periods of working with the head bent forward can also contribute to this condition. When this disease develops, the natural curvature of the cervical spine may straighten, and local cervical protrusions can cause swelling and pain. Surgical intervention may be required for treatment.

2. Hypertension

Hypertension can cause dilation of blood vessels in the head and face. When lying down, gravity causes increased blood flow to the brain, leading to cerebral hyperemia and a sensation of fullness or headache. Medications such as nifedipine controlled-release tablets or amlodipine besylate tablets may be taken as directed by a physician.

In addition to the common causes mentioned above, similar symptoms may also arise due to cerebral arteriosclerosis, tension-type headaches, cerebral infarction, or other conditions. It is recommended that individuals experiencing discomfort seek timely medical evaluation and treatment.
