[Bokeyuan - Science Popularization (If you have any questions or related questions, please leave a message in the comment area, "Bokeyuan" will select questions to give replies and answers)] Since the 14th century, the questions of the mind have confused mankind, and the sonnets and the whole book are dedicated to the meaning of love. Now scientists have discovered that the blood pump in the chest cavity is equally complex. You can't survive or love without it. Discovering more about the heart, including sex and laughter, is indeed beneficial.

TOP1, the logo of love

10oz Muscles that are full of blood are called the heart, and the heart has generally become a symbol of love. The Greeks believed that the heart was the place of the spiritual world, the Chinese linked it to happiness, and the Egyptians believed that emotions and wisdom came from the heart. Yet no one knows exactly the exact origin of the connection between love and the heart. One idea is that the heart has obtained its "love mark" in the ancient Greek city of Cyrene, and now in the modern Libyan ; the compass with heart-shaped pods are known to many people in this gathering place; the compass has medicinal value and can be used for contraception.
TOP2, Broken Heart

A broken heart can make people faint. Research shows that news of breaking up with a lover or death of a family can indeed cause the heart to "break", thereby increasing the risk of heart attacks. Such trauma will also prompt the release of stress hormones into the blood, which temporarily makes the heart "dildew". The resulting symptoms are similar to those of a heart attack—chest pain and shortness of breath, but these pains can be recovered during some TLC and rest.
TOP3, powerful pump
In less than a minute, the heart will deliver blood to every cell in the body. In a day, the heart beats about 100,000 times, transporting 2,000 gallons of oxygen-rich blood through 60,000 miles of branched blood vessels to cells in our organs and parts of our body. It's a tough job for a muscle the size of a fist.
TOP4, Drink your heart

A glass of molle red wine can directly enter the heart. Recent studies have shown that white varieties can also achieve the same effect. Scientists attribute the benefits of red wine to the heart to certain antioxidants in grape skin . Since making Chardono requires peeling off the grape skin, many scientists believe that white wine may not be of any benefit to the heart. However, an experiment on mice showed that grapes hide a heart-protecting compound hidden in the flesh, which is comparable to the substances found in red wine.
TOP5. Laughing is good for you

Laughing from the heart - especially the kind that makes you shed tears - not only warms your soul. Studies have shown that laughter can cause the inner walls of blood vessels to relax and increase blood flow within 45 minutes after laughing. Damage to the endothelium can cause narrowing of blood vessels, which ultimately leads to cardiovascular disease . This is not a joke.
TOP6, Big Heart

Some people’s hearts are indeed bigger than others. An enlarged heart is not a manifestation of emotions, but a potential heart disease. The most common type is called dilated cardiomyopathy, which occurs when the heart's ventricles stretch and expand; swollen muscles can weaken the heart's pumping force, causing the human organs to lose enough blood. If not treated in time, a large heart can lead to heart failure.
TOP7, Heart and Heart

When you see Fido or a kitten hiding from the bushes, their shy look will make you wonder if you can communicate with them. A recent study added horse friends to the list of emotionally responsive animals. A scientist discovered that the horse's heart rate reflects the tester's touch speed. Horse’s mood detectors could one day replace the program used to measure patients’ stress hormones. Next, the researchers will study service dogs in order to better match humans.
TOP8, Heart Repair
A heartbroken heart will make you feel pain, making you hope you can get a new heart, or at least have a heart repair tool. The latter option may one day become a reality. Scientists are studying erythema salamanders to help people develop cell therapies for injured hearts. This amphibian is able to transform its cells in time to build new myocardium. In another study, scientists cultivated a beating heart from embryonic stem cells in the laboratory.
TOP9, Female Heart

Girls have their own ideas on some issues, but when it comes to research on cardiovascular diseases, they will become the focus of research. Heart disease and heart attacks have been considered a male disease for decades. But this is not the case. Every year, 500,000 American women die from heart disease, and the death toll exceeds 50,000 men. Another gender difference: Women don’t experience Hollywood’s standard heart attacks—a pain in the chest makes you roll around. On the contrary, women have a feeling of tension, pain or stress, and other symptoms such as nausea, back and jaw pain.
TOP10, sex

If you can't go to the gym, try to wander around, so your heart may thank you. A study of 2,500 men aged 49 to 54 found that at least three orgasms per week reduced the mortality rate of coronary heart disease in half. In addition to potential health problems and the possibility of STD infection, sex can give you a chance to exercise. It is estimated that intense sex doubles a person's heart rate and burns about 200 calories, equivalent to the energy consumed by 15 minutes of jogging. So lying in bed may be the doctor's order.
