Palmar sweating differs from sweating in other areas. While other parts sweat due to heat, palmar sweating is often linked to overall health. So what exactly causes palmar sweating? Below we explain the reasons behind it, noting that causes may vary depending on individual constitution.
What Causes Palmar Sweating?
Palmar sweating, also known as hyperhidrosis of the palms, is a relatively common condition. However, its exact cause remains unknown, classified as a functional localized hyperhidrosis. Due to racial specificity, young people living in subtropical regions are generally more prone to this condition.
Sweat gland secretion is regulated by the sympathetic nervous system. Palmar hyperhidrosis occurs when this system becomes abnormally overactive for unknown reasons—such as anxiety, excitement, stress, or exposure to high summer temperatures—leading to excessive sweating in the palms.
Studies indicate that palmar hyperhidrosis affects approximately 0.3% of individuals aged 10 to 30, occurring equally in both genders. Notably, the prevalence rises to 13% among those with a family history, suggesting a significant genetic component. Early intervention offers benefits for future generations.
Most individuals develop palmar hyperhidrosis during childhood, with symptoms often worsening during adolescence.Individuals with palmar hyperhidrosis are otherwise healthy. Most also experience plantar (foot) or axillary (underarm) sweating, while a minority may have accompanying bromhidrosis (body odor).
We know that sweating in the hands differs slightly from sweating in other body parts. Generally, sweating elsewhere is primarily caused by heat—the hotter the body feels, the more sweat is produced.However, sweaty palms often make our bodies feel cold.
Sweaty palms indicate a cold constitution. If you also feel chilly easily and have cold hands and feet in winter, this is likely the case. Eating warming foods to regulate your body and increasing exercise to boost blood circulation and metabolism should yield good results.
Sweaty palms are related to physical constitution, endocrine function, and other factors.Healthy individuals may sweat profusely elsewhere but retain dry palms. Conversely, those prone to sweaty palms often experience no body perspiration while their palms remain drenched in cold sweat, feeling icy. Some individuals sweat more intensely on their palms during winter. The above outlines the causes of sweaty palms, which vary by constitution. We trust this provides clarity. Wishing you good health.
