今天没出汗，可以不洗澡吗？答案出乎意料

With the heat of summer right around the corner, stepping outside for a quick errand at noon can leave you drenched in sweat. While showering after sweating is an obvious solution to stay fresh, a less clear question arises: "Do you still need to shower on days when you don't visibly sweat?"

The answer, according to experts, is yes. Even without noticeable sweating, daily showers are recommended during summer months.

Human skin is densely covered with sweat glands. For instance, our palms and soles contain 250 to 550 sweat glands per square centimeter, which is roughly the size of an adult's fingernail.

While sweating due to exercise, overheating or stress is obvious, the body continuously releases moisture through a process called insensible perspiration, sweating that is too subtle to feel.

Areas with apocrine glands, such as armpits, produce thicker, oilier sweat that is rich in proteins, sugars and ammonia. When broken down by bacteria, this mixture can lead to body odor or conditions like bromhidrosis, or excessive body odor, and axillary osmidrosis, or severe underarm odor.

Beyond sweat, skin accumulates environmental pollutants, dust, natural oils, dead cells and bacteria. Regular cleansing helps prevent these deposits from compromising hygiene.

Researchers suggest showering with warm water can improve relaxation and relieve stress, and even spark creativity.
