Cats sleeping upside down will not have brain blood

No, the cat can sleep in various positions, and she will adjust her sleeping position if she feels uncomfortable.

No, animals are just like people, it's just a habit, if it feels uncomfortable, it will change its sleeping position, you don't have to worry about this.

Bats are pterocods, and pterocods are the second largest group after rodents. Bats are mammals that are truly capable of flying, but bats generally sleep upside down, and their heads are not congested, mainly for the following reasons. <>

1.Structural differences in the heart

If a person is upside down for a long time, a large amount of blood will be trapped in the head and cannot return to the heart, causing the head to be congested and causing discomfort. This is mainly because we have venous valves in the veins of our limbs that only allow blood to flow from the top down, thus preventing blood from flowing backwards。The bat does not have this structure, but the muscles of its vein wall are strong and contractile, and even if it sleeps upside down, it can actively constrict blood vessels and promote blood flow back to the heart.

2.The heart is well developed

Bats need to consume a lot of oxygen to fly, so their hearts are particularly developed. In addition, the right atrium of bats is also relatively large, which can make a large amount of venous blood flow back into the heart.

3.Bats are small in size

Compared to us, bats are very small. Their gravity is not strong enough to affect the flow of blood, and their hearts are more capable of pumping and can completely resist the gravity of the blood. <>

In fact, the bat sleeps upside down because it is not able to take off directly from the ground like other birds. Its wings are a thin layer of skin, and the wings of birds are full of muscles. Therefore, most bats will choose to rest at a high place and get the starting power to fly by falling down their bodies.

Due to the bat's special claw structure, it is comfortable when it hangs upside down. Even if the bat dies while sleeping, it will hang on until an external force removes it. <>

Bats are very capable of flying, but they are also natural hosts for many zoonotic diseases. It is capable of carrying more than 10 viruses and is virtually immune to infection. So we can't eat this kind of wild animals, they don't belong to our human table, once they cause an epidemic, they will harm others and themselves.

This should be because the physiological structure of bats is different from ours, our blood vessels will only flow passively in one direction due to the limitation of valves, while the veins of bats do not have venous valves, and bats can also actively constrict blood vessels to let blood flow back to the heart, so there is no congestion.

Of course, this is due to the physiological structure of bats, they themselves sleep upside down, of course the head is not congested, if it is congested, why do they sleep upside down?

Bat blood vessels do not have valve-like structures in them, but their vein wall muscles are strong and can contract rhythmically. Most mammals, including us humans, have a passive flow of venous blood, but bats can actively constrict blood vessels and facilitate blood flow back to the heart.

Why do bats like to sleep upside down, because it allows for better predation. The ancestors of bats actually lived in trees, and bats preyed on small insects as they moved along the bark. Because it is much more difficult to chase insects in trees, bats will wait face down for their prey to climb up the trunk.

This way, if the bats see a suitable prey, they can easily run down. There is also low energy consumption. Bats grab their prey with their hands and beaks and hang down from their hind legs.

This causes their paws to adapt, allowing their tendons to lock into place when suspended. That's why bats can hang upside down without using muscles and with little to no energy. Gravity does all the work for them.

Because it consumes the least amount of energy, it is the best way for bats to sleep. So there will be no congestion problem.

Normally, there will be no problem, and the headstand is a professional action, and it is not suitable for individual people. If you want to do this kind of action, it is best to find a professional to guide you to do it.

This is called a microstand. According to the description in Mr. Guan Feng's book "Human Handstand Fitness Exercises", the action of micro-handstand can alleviate many diseases. Mr. Guan Feng has a number of successful cases.

In addition, there is a kind of bed called an inverted bed, which sleeps on the ground with head and foot, which is also based on this principle.

The same goes for inverted machines.

Of course, the same goes for handstands.

It is good for the body, reduces the burden on the heart, and helps blood circulation. Those who are in good health and those who have adhered to it for a long time can do this, and those with high blood pressure, heart disease, and the elderly should be cautious.

How can a handstand make the mind clear, and how can the head be congested to make the mind clear, there is no such saying.

It's about letting the blood flow.
