The harm of sleeping on the table for a long time
1, inducing ulnar nerve disease in elbow.
Sleeping on the table requires the elbow to bend outward greatly, which is easy to make the ulnar nerve between the skin and bones of the elbow injured due to long-term compression, forming ulnar neuropathy or nerve adhesion, resulting in pain and numbness of the little finger and ring finger.
2, damage to the eyes
Sleeping on a table usually involves resting your head on your arm, which may cause eye compression, and even lead to high myopia and glaucoma in severe cases.
