Physical differences between men and women

There is an old saying: "Two rabbits walk side by side, how can you tell which is male and which is female?" This mainly means that there is no difference between males and females. In fact, it is easy to tell the difference between girls. Although in today's society, there are many boys who look delicate like girls and girls who look handsome like boys. However, no matter how similar men and women are in appearance, there are always big differences in their bodies.

Date affects pain

If you get a prick on your finger during your menstrual period, it will feel more painful than at other times of the month. Researchers at the University of Michigan have found that estrogen levels in the human body play a key role in the brain's ability to inhibit pain, and estrogen levels are higher during menstruation.

Women wake up from anesthesia faster

Experiments have shown that it takes an average of 11 minutes for men to wake up after anesthesia, while it only takes 7 minutes for women. This may be because women are more sensitive to anesthetics than men. Therefore, if women need to trim their eyebrows, remove hair, or have their teeth filled, and are afraid of pain, it is recommended to do it before ovulation.

Quitting smoking is more beneficial to women

Compared with male smokers, female smokers have a higher risk of heart disease and are more likely to suffer from chronic obstructive pulmonary disease, the most common of which is emphysema. For women, smoking causes more deaths than breast cancer. Smoking increases the risk of at least 10 types of cancer, and female smokers are more likely to get lung cancer.

1 in 4 women lack iron

A recent nutritional survey found that many women do not get enough iron. Iron is a trace element in the human body and is an important component of hemoglobin, which transports oxygen in the blood. Red meat (such as pork, beef, etc.) is the best source of iron. Green leafy vegetables, beans, dried fruits, bread and cereals also contain iron. For the human body, the iron in vegetarian food is not as easy to absorb as the iron in meat, but vegetables and fruits rich in vitamin C are also necessary - vitamin C can promote the body to better absorb iron. When eating, remember not to drink coffee or tea at the same time, as they will affect the absorption of iron.

Periodontal disease can lead to premature birth

Studies have shown that once pregnant, women with severe periodontal disease are twice as likely to have premature babies as healthy women. Researchers at Alabama State University found that bacteria produced by periodontal disease can increase the level of hormones in the body that speed up childbirth. If pregnant women receive regular dental treatment, their chances of having premature babies can be reduced by more than 84%.

Heart disease symptoms vary widely

For some women, the symptoms of heart disease are the same as for men. However, for many people, heart disease symptoms are unique to women, such as indigestion-like pain around the breastbone, shortness of breath, extreme fatigue, and general malaise, rather than the typical chest-pressure pain.

High heels really hurt your feet

Wearing high heels too often can cause swelling of the big toe, calluses and corns on the feet. These symptoms not only affect your feet, but also affect your standing posture, which puts more pressure on the spine, leading to a series of back diseases. Wearing high heels for a long time can also cause the calf muscles to atrophy, leading to a series of problems in the back, hips and knees.

Women should pay more attention to bone protection

80% of osteoporosis patients are women. Estrogen in women can protect bones from loss, but after menopause, estrogen levels begin to decline. 5-7 years after menopause, women will lose 20% of their bones. But don't worry, osteoporosis can actually be prevented. Do more weight training, quit smoking, and supplement with the right amount of calcium and vitamin D to help you stay away from osteoporosis. As long as you pay attention to getting more sun, your body can also synthesize vitamin D. New research shows that vitamin B group, vitamin K and trace element zinc are all important for taking good care of your bones.
