  Studies have also found a pattern: people who "eat out" more are, on average, sicker and live shorter lives. In 2021, a study in the United States counted 35,084 adults. Among them, those who ate takeout two or more meals a day had the highest risk of death during the study period (1999 to 2014). They had 1.49 times the all-cause mortality, 1.18 times the cardiovascular mortality and 1.67 times the cancer mortality compared to those who ate out less than 1 meal per week Eating out all the time is unhealthy, which is probably in line with many people's intuition. But what is so mysterious about restaurant and take-out food that it can be so much less healthy than at home? The obvious answer is that take-out food is made with more oil, salt, calories, and possibly hidden harmful substances such as gutter oil. This is true. But high oil and salt, high calories, are not the only hazards of "eating out", even if you choose healthy dishes as much as possible, you c...

  How about if you just do not exercise all the time? Those who do not exercise for a long time, what happened to them? When we have just stopped exercising: Stealing lazy, really comfortable It's true that when you don't exercise for a while, you feel better. I just stopped exercising for a period of time, but my body feels better, and the whole person is still fresh. As soon as you stop exercising , a series of changes in your body that are not easily noticeable from the outside come into play. Caloric demand decreases, and mitochondria, a part of the body's "energy station" that converts energy, begin to shut down. There are also changes in the metabolism of fat, which is the fuel. Even if you don't exercise for just two days, your body's low-density lipoprotein cholesterol (LDL-C) levels may rise by 10%, and high LDL-C levels carry the risk of cardiovascular disease. LDL-C concentration over time in the non-exercise group (top line) in the study Aft...

Wake up early and don't get enough sleep I don't like who I see Adequate sleep can cure a day, while lack of sleep, with a day may not be able to cure. Studies show that when sleep deprived, the brain is more inclined to interpret other people's expressions negatively. Simply put: it's not good to look at anyone. It is clear that there is no emotional "neutral expression face", people who have not slept enough will mostly interpret it as "threatening". In other words, when you go to bed late and wake up early resulting in sleep deprivation, you will feel that other people are more threatening, less trustworthy and more likely to be hostile to others. Just not enough sleep Grumpy When you don't get enough sleep, you are more likely to get into conflict with others. It's like a powder keg, a little goes a long way. This is related to the activity of the amygdala and prefrontal cortex . The amygdala and prefrontal lobes are two structures in...

  It is human nature to refuse sweets, and modern people are really afraid of gaining weight, and eating too much sugar can bring many health problems. So sugar substitutes have become the perfect choice for many people: they are "sweet free" and low in calories, which is a two-for-one choice for many people. But although sugar substitutes are good, you can't be greedy. For example, erythritol is a widely used sugar substitute in many sugar-free drinks and foods. Recent studies have found that although it is low in calories, it can increase the risk of cardiovascular disease to some extent. Sugar substitute, not a perfect substitute for sugar A recent paper published in the journal Nature Medicine confirms that there may be a causal link between the intake of polyol sweeteners, particularly erythritol, and increased cardiovascular risk. In separate studies conducted in the United States and Europe, covering 2982 individuals at high cardiovascular risk, erythritol intake...

  At the beginning of exercise: muscle soreness Many people assume that the soreness after exercise is due to lactic acid buildup. But this soreness has a specialized medical name: delayed onset muscle soreness ( DOMS ). Researchers have found that lactic acid returns to its previous level soon after exercise, and that soreness is more likely to come from microtrauma to the muscle fibers and secondary inflammation. It tends to hit 12 to 48 hours after strenuous exercise and then disappears after 2 to 10 days. Micro-trauma of muscle fibers is a sure way for muscles to get stronger. As the saying goes, you can't get stronger without breaking down, and this is true in the body. As your body gradually adjusts to the intensity and duration of the exercise, the soreness decreases and the sweetness that comes after the pain begins to appear. First is the increase in resting metabolic rate. That is, the rate at which calories are burned when used only to be to maintain basic physiological ...

  Consistently apply body lotion What will happen to my skin? As we all know, many parts of the body do not produce much oil compared to the skin on the face. Especially the front side of the calf, which is the hardest hit by dryness. What changes can be made in just one week? Come  hold on to your seat, we take you in 400 times the lens to watch the results of the experiment. After 7 days, the left leg, which had continuously applied body lotion, had moisturized cuticles and significantly reduced flaking. On the other hand, the right leg, which had been "cut off" for 7 days, was a patchy mess. When I touched it, I felt a little bit sad that I have a different life from my mother. Body Lotion How does it make the skin look better? Our skin is protected against external stimuli and damage by the skin barrier consisting of the stratum corneum + sebum membrane. Stratum corneum: like a 'brick wall' Sebum membrane: like a 'waterproof membrane' As we age, oil secre...

  An article published Feb. 16 in the subjournal Nature found that some women are more likely to put on a small belly, which is actually influenced by genes. New study reveals fat belly gene The research team first compared the genomes of hundreds of people to identify genes associated with obesity and high Waist-to-Hip Ratio . The  Waist-to-Hip Ratio  is a good indicator of abdominal fat, and the higher the ratio the less healthy it is. After genetic analysis, they targeted genes associated with 91 genes that help regulate fat distribution primarily in women. One gene in particular caught the researchers' attention as having the strongest association with waist-hip height in women ----SNX10 Although men also express this gene, it does not affect the waist-to-hip ratio in men. After various verifications, it is true that this gene is the biggest suspect in causing abdominal obesity in women! First, this gene has the ability to control the growth and deposition of fat cell...

  Who is best suited to write about the topic of 'female menopause '? Naturally, women who have gone through menopause , such as Susan P. Mattern, a researcher in history at the University of Georgia in the United States, who has written a book, The Slow Moon Climbs: The Science, History, and Meaning of Female Menopause . Susan Mattern wants to challenge the 'common sense' about menopause. Is menopause really a disease? Is it possible that the early loss of fertility in women is not a 'mistake', but an 'advantage'? Menopause is an evolutionary advantage Of all the animals in the world, only three are known to have menopause - orcas, short-finned pilot whales, and humans. The rest of the animals can reproduce until they die. Take our close relative, the chimpanzee, for example. Chimpanzee fertility peaks at 25 to 30 years of age and then gradually declines, reaching zero at about age 50. But 50 years is also about the limit of chimpanzee lifespan; in the ...

  Women, more than men, need more iron Usually, many women always have a lot of unanswered "difficult problems", some are minor, some are very troubling, always think that this may be "a common problem of girls", such as. Cold hands and feet Headaches, dizziness and lightheadedness Extreme fatigue and weakness Pale skin, mucous membranes of the mouth and lips, brittle nails Chest pain, rapid heartbeat and shortness of breath All of these symptoms are most likely related to one problem - iron deficiency anemia. Relatively speaking, women are indeed prone to iron deficiency, and iron is one of the few nutrients that women need much more than men. This is related to the physiological state and needs of women. Increased loss of iron due to menstruation Some studies have shown that healthy women with normal menstruation lose an average of 1mg of iron per menstrual cycle, which needs to be compensated by diet. Increased iron requirements during special periods of pregnanc...

  Many people habitually attribute this to a problem of personal self-control, but in fact, it is a "psychological disease". This irresistible, compulsive late sleep is academically called (revenge bedtime procrastination). What time you go to bed is essentially the node that determines the end of the day. Retaliatory sleeplessness, on the other hand, is a phenomenon in which people who have little control over their daytime lives refuse to go to bed early in order to regain a sense of freedom late at night. Forcing yourself to "go to bed earlier" does not solve the problem. Stay up late and become the only way to control time When work deprives people of leisure time, they have no choice but to deprive themselves of sleep. Sleep is alienated into an ATM machine, and one can decide how much time one wants to withdraw. Whether it is to relieve the pressure of life, or purely for the sake of domination, "giving up part of your sleep time" sounds like a sen...
