The common clinical causes of sweaty feet under the covers in winter include high ambient temperatures and restrictive hyperhidrosis.
1. High ambient temperature: when the ambient temperature rises, the body usually sweats to maintain normal body temperature, so the winter quilt may cause feet sweating, which is a normal physiological phenomenon.
2. Restricted hyperhidrosis: this condition is mostly seen in young adults with large emotional fluctuations, and is usually associated with sympathetic over-excitement caused by a variety of reasons, such as nervousness, anxiety, over-excitement and other abnormal emotions, which may cause an abnormal increase in sweating in the palms of the hands, feet and other parts of the body.
If the symptoms persist after adjusting the ambient temperature, it is usually considered to be a disease factor, and it is recommended to go to the hospital for treatment.
