What will happen to the animals when they drink coffee?Spider: I won't be woven by my net

Coffee is one of the most popular drinks in the world. Many people choose to drink coffee, not only because of its unique flavor, but also the caffeine that can "renew" in coffee.

It is generally believed that when we drink coffee, our central nervous system will be excited, which will increase alertness, make people's thinking clearer, and increase attention.

However, this is just the role of coffee on people. For some other animals and plants, coffee may have a more magical or dangerous effect.

It is more troublesome to examine the impact of caffeine on animals. To observe their behavior, measure physiological characteristics, etc., this is especially true for small non -vertebrates. However, there is a unique advantage in the eyes of scientists. It is a spider.

After watching the condition of the spider after drinking coffee, scientists have proposed that they can directly look at the pattern of the spider web!

In 1948, Pharmacist Peter Witt allowed the spider to drink 10 μg caffeine, and found that the net out of the spider became smaller and the radius became uneven. When the spider drinks 100 μg caffeine, the shape of the net has changed a lot, and it looks very irregular.

This shows that caffeine has an impact on spiders. The greater the dose, the more significant the resulting results may be. The use of spider web patterns as statistical tools have also become a simple drug detection method.

For vertebrates like spiders, the effect of coffee on the nervous system may be fatal. When a scientist allows a common moth larvae (tobacco moth larvae) to drink a higher concentration of tea or coffee, the larvae will be killed within 24 hours.

When mosquito larvae drink coffee, their movements will become less coordinated, and they are finally drowned because they cannot swim to the water.

However, this may be a good thing for plants? Some plants have caffeine itself, which can be used as "natural pesticides" to kill some insects. Moreover, caffeine also inhibits the growth of other plants and strives to survive.

In addition, plants can really drink coffee. The appropriate amount of coffee or coffee residue is the nitrogen source of the plant (about 2%of the nitrogen content), and it can also provide trace elements such as calcium and magnesium.

However, don't forget to pour the flowers after diluting coffee, otherwise your flowers will be like the figure below. After all, high concentrations of coffee can't stand it whether it is animal plants or people!

Pets may know that for dogs and cats, coffee will significantly change heart rate and breathing frequency, and life -threatening is endangered; the parrot will damage the digestive system; coffee will also cause frog heart disease, suppressing food for snails ... It seems that although coffee means more sober to humans, for animals, caffeine is difficult to metabolize and easily live life.

Coffee can only be a human drink? This view is quickly proven to be one -sided, because some animals also enjoy the positive effect of coffee.

The study found that when the horse drank coffee, the heart rate increased significantly, showing extraordinary endurance, jumping ability and speed. Moreover, like people, the fatigue after drinking coffee is also small.

But because of this, caffeine has also become a "stimulant" in the horse racing. Because it can change the performance of horse racing, it is set up as a banned drug by the authorities. The same situation also appeared in the pigeon competition.

The bee also tasted the buff given by caffeine. Some scientists have found that the bees tasted citrus (such as citrus flowers) with caffeine, which seems to improve memory.

After 24 hours, the bees who drank the "coffee honey" reminded the smell of flowers by 3 times. This means that bees can find pollination routes, and those flowers can multiply their offspring more successfully!

However, the impact of coffee is often not so simple. Further studies at the University of Sussex found that the bees who drink coffee will also swing in the hive and tell other bees where to find food, so that everyone can eat caffeine nectar. Looks like the taste of coffee like humans? And this is still controversial whether the bee is positive or negative.

Today, scientists have not really figured out the effects of caffeine on various animals, plants and even the human body.

In the Stone Age, people found that chewing some unique bark or leaves can refresh their brains. In the development of thousands of years, coffee has also undergone various changes from medicines, goods and drinks. At present, the chemical response of caffeine in the human body is still very complicated.

The role of coffee varies from person to person. | Giphy

Even if it helps relieve fatigue, it is only a temporary role. And everyone's body shape is different from caffeine tolerance, and the performance of coffee varies from person to person.

Although coffee is a delicious drink for some people, about one -tenth of the world will have a series of bad reactions of physical and psychological -related reactions after drinking coffee.

So what is the meaning of coffee to you?Also remind: For most adults, the normal coffee dose is 400mg per day.Although coffee is good, don't be greedy
