Why do girls feel weak in the legs?
Girls' psychological excitement, excitement, tension and other factors during kissing make their bodies hot and their heads dizzy. Then they have difficulty breathing and their faces turn red.
So at this time, the brain will send signals to the adrenal glands, which in turn release hormones such as adrenaline and norepinephrine. These hormones pass through the blood and make your heart beat faster and deliver more blood to the brain. The heart supplies all the blood upward, resulting in temporary lack of blood and oxygen supply to the lower body, which is an important reason for the soreness and weakness of the legs.
Especially the long French kiss, girls said: "This kind of kiss is going to suffocate me!" For this physiological reaction, girls must learn to breathe, we are not in a hurry!! Gay men must also learn to adjust their girlfriends' breathing. Look at your abyss mouth that completely covers your girlfriend's cherry mouth. How uncomfortable your girlfriend is.
Most people feel their heartbeats accelerate when kissing. When a man kisses, his pulse rate can suddenly rise to 110-120 beats per minute in a short period of time. For women, their heart rate can rise to 180 beats per minute. When kissing, the frequency of breathing can be instantly increased, the heartbeat speeds up, the heart rate rises, the muscle tension increases, and our breathing rate speeds up.
These are equivalent to you going to the gym to do a high-intensity training. Therefore, when you kiss your lover (to be exact, it should be a hot kiss), you can feel the body sore and the whole body is hot. It is the feeling of being loved.
When people kiss, the body produces a lot of dopamine. Dopamine is a neurotransmitter, a chemical used to help cells transmit pulses. This brain endocrine is mainly responsible for the brain's lust, and the feeling of transmitting excitement and happiness is also related to addiction. Love is actually the result of the production of a large amount of dopamine in the brain due to related people and things.
Therefore, when you kiss, dopamine will prompt you to want more and stimulate the body's sexual desire. The physical manifestation is that as the kissing goes deeper, the body parts gradually become hotter from insensitive to sensitive.
Especially the sensitive parts of girls react the most strongly, they will heat up, contract unconsciously, and tighten their legs. Gradually, a liquid is secreted, causing women's legs to tremble involuntarily.
