What are the harms of sleeping on a hard bed for a long time?

The potential harms of long-term sleeping on a hard board bed may include affecting sleep quality, increasing pressure on spinal joints, causing skin abrasions, affecting blood circulation, and emotional problems. A detailed analysis is as follows:

1. Impact on sleep quality: Hard board beds are firm in texture, concentrating body pressure on several prominent contact points, which can restrict local blood circulation and easily affect sleep quality.

2. Increased pressure on spinal joints: When sleeping on a hard board bed, pressure between spinal joints becomes concentrated on a few points, causing excessive wear on joint cartilage. This may easily lead to joint degeneration, bone spurs, and other issues.

3. Skin abrasions: The surface of a hard board bed is relatively coarse, creating significant friction against the skin. Frequent body movements during sleep can cause skin abrasions due to contact with the bed surface.

4. Impaired blood circulation: Long-term sleeping on a hard board bed may cause poor blood circulation in the buttocks, leading to symptoms such as numbness and coldness in the buttock skin, and could even affect blood circulation in the lower limbs.

5. Emotional problems: Long-term sleeping on a hard board bed may lead to insufficient sleep, causing emotional instability and easily triggering negative emotions such as anxiety, depression, and irritability, which can adversely affect mental health.

It is recommended to choose a mattress of appropriate firmness based on individual physical condition and sleeping habits. If discomfort occurs, timely medical consultation is advised.
