What are the benefits of sleeping on a mat? Still have many shortcomings?

There are many places to pay attention to when sleeping on a mat. The advantage is that it is cool and easy to fall asleep. But I think there are many disadvantages. Summer sleeping mat is not suitable for everyone. When the human body is cold, it is not suitable for sleeping on a mat, such as skin chills, joint pain, abdominal cold pain, etc. People with cold back, frequent urination and cough are not suitable for sleeping on a summer mat, nor are diabetics, because summer mats are easy to scratch their skin, while diabetics are prone to infection after skin injury due to high blood sugar, and the wound is difficult to heal. The room temperature of the sleeping mat should not be too low. Adding cold is not good for health, especially for the frail elderly and those who have suffered from spinal diseases and scapulohumeral periarthritis, which will lead to the recurrence of old diseases. When the human body is cold, the muscles are tight and the joints are sore, which is not suitable for sleeping on a mat. Patients with scapulohumeral periarthritis should not sleep on a mat.
