Why do your palms have a lot of tiny holes in them?

The tiny holes in your palms are sweat glands, specifically eccrine glands, which help regulate body temperature through perspiration. These glands release sweat onto the skin's surface, allowing for cooling through evaporation. The palms have a high concentration of these glands, which is why they can become sweaty during stress or heat. Additionally, the small holes can also be seen as hair follicles, though palms typically have fewer hairs than other parts of the body.
