Will your breasts get smaller if you drink coffee a lot? Is it suitable for coffee before having sex? Do you feel sleepy after drinking coffee?

We all know that drinking coffee is good for the human body. We all know that drinking coffee is good for the human body. As a drink, it is of course important whether it tastes good or not, but obviously, it is not enough. There are often some strange coffee problems about the efficacy of coffee. Today, let's take a look at popular science:

For example, some scientists go to study the relationship between women's breast size and coffee intake, so some people will ask:

When women drink coffee, their breasts get smaller?

Some researchers found that the 269 healthy women who participated in the survey had two different genes, one with the CYP1A2*1F C-allele gene, which we call gene A, and the other with the CYP1A2*1F A hand A gene, which we call gene B. Women with gene A had smaller breasts than girls with less coffee if they drank a lot of coffee every day, while women with gene B had little to do with breast size.

It can't be proved that drinking coffee leads to small breasts. At present, there is no other evidence that drinking too much coffee will make the breasts smaller, and if you don't drink them, you don't see big breasts.

Often drink coffee, bosom is big bosom is small oneself in the heart does not order B number? Don't believe all the rumors.

Netizen @ sherry: no, I have one or two cups a day. I don't remember how many years. C is all right.

Netizen @ I am Miss Zhao: my boyfriend said, I'm not afraid, drink, anyway, it can't be any smaller. I'll go.

Netizen @ Chen Xiaoqi: what about my little girl with coffee breasts? [collapse]! Add another cup of milk every day, is it "flat"? as a dead star if you don't drink coffee, or give up the treatment, tell me what breasts will get bigger, I'll try!

For example, some people want to study whether Pu'er tea can improve the relationship between husband and wife.

Is it suitable for coffee before having sex?

The study found that coffee has a refreshing effect because it contains caffeine. Of course, it is not just coffee that contains caffeine. Green tea, black tea and so on also contain caffeine. So, what effect does this kind of caffeine have on sex? Before answering this question, we must first explain what is meant by the refreshing effect.

For example, when people feel dizzy, drink a cup of coffee or black tea, the mood is immediately refreshed, this is because the caffeine in its ingredients stimulates the sympathetic nerve. To put it simply, it is the sympathetic nerve that is in charge of all the activities during the day. As long as you stimulate it, you can regain your energy and everything becomes more active.

From another point of view, this matter is tantamount to the suppression of the parasympathetic nerve. Because the sympathetic nerve and parasympathetic nerve belong to the relationship between exterior and interior, when the sympathetic nerve is active, the parasympathetic nerve, which is weaker than the sympathetic nerve, is suppressed. In the physiologically related part of the parasympathetic function at night, excessive caffeine intake can have a negative effect on sex.

Experts say, usually emotional ups and downs, sympathetic nerve easily excited people, especially before sex, it is best not to drink some caffeinated coffee and other drinks, so as not to suppress the parasympathetic nerve and reduce desire.

To this profound question, an enthusiastic barista gave a textbook answer: first of all, you have to have a girlfriend!

Why do I still feel sleepy after drinking coffee?

I went to a doctor today and asked: I get sleepy as soon as I go to work.

After feeling the pulse, the doctor advised me to exercise more, drink more boiled water, ride a bike or walk more, don't eat out, try to be vegetarian, and eat less meat and seafood!

I nodded and asked him:

"what's wrong with me? "

The old Chinese medicine doctor said, "the income is too low!" Too much pressure, sleepy as soon as I go to work! As soon as you spend money, you get angry! "

Divine doctor!

Then one of the people in the group will always say, "I don't know why. People say it's refreshing, but as soon as I drink it, I get sleepy." "or" No, I'll fall asleep as soon as I drink it. "

Drinking coffee is not refreshing, but people who want to sleep more and more are probably not. After careful analysis, there may be the following reasons why drinking coffee does not lift one's spirits:

Physical factors. You have a lot of powerful caffeine antibodies in your body, which resist the refreshing effect of caffeine.

There are substances that convert or resist caffeine in the food or drink you eat at the same time. You are so sleepy that even coffee can't compete with your drowsiness.

Age difference: with age, there are fewer and fewer receptors in the brain that can dock with caffeine. Obviously, the 27-year-old post-90s barista has entered middle age!

The effects of caffeine range from two to three hours to as long as four or five hours, depending on everyone's sensitivity and metabolic rate to coffee. Researchers at the University of Barcelona report that it takes only 10 minutes for coffee to work; it takes 45 minutes for caffeine to reach its maximum in the bloodstream, but it takes only a few minutes to reach half of it.

Finally, there is the habit factor: if you drink a lot of coffee over a long period of time, the brain will release fewer and fewer receptors-coffee will have less and less effect because of habit.

At the beginning of the editor, drinking coffee is also refreshing, basically the kind that can stay up until dawn in a cup. Now even if you drink four pure espresso at night, you can fall asleep immediately.

It's not sleepy after drinking coffee, it's really sleepy!

Sleepy in winter, sleepy in summer, sleepy in spring, sleepy in autumn

Sleepy at work! Sleepy at school! Sleepy to eat! Sleepy 365 days a year!

Ha, it doesn't seem to be about drinking coffee.

Can pregnant women have coffee?

Only excessive caffeine intake increases the risk of miscarriage, and the safe daily caffeine intake during pregnancy is 200mg.

A cup of (240ml) instant coffee contains roughly 90-200mg caffeine, while a single cup of coffee has less caffeine, so one cup of coffee a day is safe (in fact, domestic doctors recommend not drinking coffee, and few Chinese pregnant women drink coffee every day, so let's follow the doctor's advice).

Coffee is loved by white-collar workers, but coffee also has inappropriate people, not a "national" drink.

For example, people with high blood pressure, coronary heart disease, arteriosclerosis and other diseases who drink coffee for a long time or in large quantities will increase the content of cholesterol in the body; patients with stomach problems can easily stimulate their intestines and stomach by drinking strong coffee; and children have poor detoxification ability due to the incomplete development of liver and kidney.
