When humans sweat in hot weather, will plants "sweat"?

On rainy nights or early mornings in spring and summer, you can see some plants such as wheat, corn, cabbage, tomato, Yuexi, etc., and sparkling water drops are hung on the tips or edges of leaves. Because dew is on leaves, it is often mistaken for dew. Actually dew is not dew. So, where do these small water droplets come from? It turned out to be the liquid oozing from the inside of the leaves. This phenomenon is called "spitting". Plants that can spit water have water holes at the top or edge of leaves. In hot and humid nights and mornings, or in plastic greenhouses, the transpiration of plants will be weakened, but the roots will continue to absorb water and transport it to the leaves, and excess water will seep from the hands, just like plants sweating. In the same environment, the more water plants spit, the more developed the roots and the better the growth momentum.

We all know that our bodies should keep a relatively stable temperature. Once the temperature rises, the brain will send out instructions to sweat quickly. At this time, all the glands begin to work, and sweat will be ejected from the pores. Trees sweat, usually from the pores of leaves, but trees sweat not to lower their body temperature, but to transport nutrients. We all know that the roots of plants can absorb nutrients and water, but have you ever thought about how plants transport these substances to the top of trees above 10 meter or even 100 meter? Please think about it. If you live on the 10 floor and the pump just breaks down, how hard will it take you to send the small bucket of water home?

It is believed that this tree carries water through Moses' actions. Moses' function is simple, that is, to "climb up" along a very thin tube. We can experience it in thinner glass tubes at home. The thinner the glass tube, the higher it climbs. However, through calculation, it is found that the Moses effect caused by the size of the big tree conveying pipe (blood vessel mass) can not send water to a place tens of meters high. There is a personal difference in how much you sweat. Generally speaking, sweat glands have sweat, sweat and sweat. Fat people sweat more, while thin people sweat less. Infants with vigorous qi and blood sweat more, while elderly people with declining physique sweat less. Exercise sweats more, exercise sweats less. When the weather is hot, you sweat less when it is cold.

The stress is too great, and the autonomic nerve function is easily disordered, leading to anxiety, depression and sweating. American studies have found that when people are under great pressure, glands will produce sweat. Glands are distributed in axilla, areola, anus and other specific parts, which are more prone to "stress sweat". This kind of sweat contains fat and protein, which is easy to produce sweat odor when mixed with bacteria on the skin. Experts pointed out that in order to reduce "stress sweat", we must learn to relieve stress. When the "stress sweat" comes out, deep breathing, drinking water, eating fruit and drinking milk can all relieve the pressure.
