  Have you ever wondered what would happen to your body if you didn't drink for 100 days? A British brother named Jonathan Thompson, decided to personally do a 100-day non-drinking challenge to see what would happen. The first week without alcohol More awake during the day and sleep well at night Many people have experienced this: the day after drinking, dizziness, headache, and even feeling a bout of nausea coming from the stomach ...... This is the physiological reaction brought on by alcohol and acetaldehyde, the metabolite of alcohol. The good thing is that the body can metabolize alcohol in a day or so, and the benefits of not drinking soon appear. On day 3 of sobriety, Jonathan felt better than ever in the morning: happy and clear-headed. Nice early morning. No hangover is a bonas. This is because, while drinking alcohol makes you sleepy, it also makes the quality of sleep worse. Under the influence of alcohol, we miss some important rapid eye movement (REM) sleep in the slee

  Wiping our bottoms is an essential part of the thank-you process after every poop. Although we have been practicing this skill over and over again since we were kids, the reality is that many of us have probably never wiped our bottoms! A microbiologist in the United States once found that each pair of underwear surveyed contained an average of 0.1 grams of feces. So today, let's explore how to wipe our butt clean scientifically! round 1 We decided to simulate the scenario with a Chinese steamed bun! As you can see, lifting upwards, it is actually difficult to wipe clean. This is mainly because of these grooves in the farts, a single direction of wiping is easy to miss part of the gap, and these gaps are easy to hide dirt, like this - And the solution to the gully problem is also very simple, as much as possible to let the paper towel contact the gully, on the line! By pressing, it fits more closely to the grooves of the buttocks, thus better wiping clean. See, compared to the co

  When an earthquake comes, to run or not to run? To put it simply, don't run. However, some times, there are still people will run, not only the epicenter of the run, hundreds of kilometers from the epicenter of the city also run. In fact, think about it, if the magnitude of the earthquake, intensity, the whole earth shaking up and down, horizontal shaking very violent, where you can run? Run a step on the fall to do not know where to go! On the contrary, if you can successfully run downstairs, it is certainly running for nothing! So we usually say: small earthquake do not need to run, big earthquake can not run. Again: Unless you are on the first floor, and out is the square without falling objects, otherwise, do not run! Must not deliberately hide in the bathroom Those who do not run, there are many people think of running the bathroom to hide. But in fact, now the frame structure of the building, the bathroom is not more solid than the living room, bedroom. Therefore, the last

  Imagine you walk into a room with unlit cigarette butts thrown on the floor, on the coffee table, and several people in the room with a few in their mouths. This is the all-too-common scene of us inhaling secondhand smoke. But this cloud of smoke is only on the surface. What's going on behind the scenes is something you may never have thought of - the room is slowly releasing a kind of smoke that contains more than 7,000 chemicals, more than 70 of which are known carcinogens. At the same dose, sidestream smoke may be more toxic than mainstream smoke, and 85% of the secondhand smoke we inhale is sidestream smoke. When a person smokes, the smoke produced by the tobacco enters his mouth through the mouthpiece, which is the mainstream smoke; and at the end of the tobacco, the smoke released from the burning butt is the sidestream smoke. Incomplete combustion of sidestream smoke, higher toxic gas content Just like firewood. When well ventilated, the fire burns fully and the air is cle

  Open this article everyone, where is the hand that does not hold the phone now? Bet there are a lot of people who are touching their faces! Humans all over the world can not control the habit of touching the face, and a person touches the face more times a day than you can imagine. In order to be healthy and reduce the chances of being infected by the outside world, we have various protective measures: washing hands regularly, keeping social distance ...... But there is an important detail that many people may not think of at once, it will greatly increase the risk of being infected, and that is - touch your face with your hands. The intact skin is an important barrier to protect the body from viruses, and viruses cannot enter the body from the intact skin of our hands. But for the mucous membrane covered areas, such as the eyes, nose and mouth. If unclean hands touch these areas, the virus can take advantage of the situation and greatly increase our risk of being infected. But in re

  As we get older, the lipids in our adipose tissue get older. Even if we maintain the same diet and exercise as when we were younger, we may gain weight more easily with each passing year. In other words, gaining weight in middle age may be a fundamental setting of the body. Even if you don't gain weight, your body is storing fat every day A fat cell is essentially a large oil droplet, packed with energy-storing lipids (triglycerides), and its size usually determines whether a person will gain weight or become thin. Many people may think that by ensuring a balance between daily caloric intake and consumption, no new lipids will be produced into the cell. Wrong! Whether you gain weight or lose weight, your body will synthesize new lipids as long as you eat. Fat cells are dynamic tissues where large amounts of lipids enter and exit every day, like a "job center:" Absorption: a large amount of new lipid enters the cell after a meal, waiting for an opportunity. Removal: lipi

  Recently, "scientists have developed a male contraceptive pill" topic on the hot search, male contraceptive pill is not something new, some male contraceptives have reported new developments in the past few years, why is this study so much attention from the academic community and the media? Because, it does sound quite reliable: Fast-acting, easy to use, very high contraceptive rate, no hormonal changes, no impact on fertility, no observed side effects ......

  In recent years, more and more people are saying: chocolate is actually healthy - especially dark chocolate, which is not only low in calories, can help you lose weight, but also has anti-inflammatory and antioxidant properties, and is simply a super food. Chocolate for weight loss It may be a misunderstanding Many people have heard that "black chia can help you lose weight". Indeed, some studies have found that black chocolate has some appetite suppressing effect. This effect is partly due to caffeine and partly due to the smell of cocoa. Just smelling dark chocolate, without even eating it, makes a person feel fuller; smelling milk chocolate is almost useless. In addition to suppressing appetite, the glycemic index of dark chocolate is relatively low compared to other dessert snacks. However, these tests have limitations and limited guidance. And you can't just munch on chocolate whenever you want to eat. Chocolate itself is a small calorie bomb - dark chocolate is ev

  Sleeping is important, and so is having a partner, and what if those two things happen together? There is really an unexpected benefit: people who sleep better with a partner in the same bed. And, the better the relationship partner, the better the sleep. The more time you spend together, the better you sleep Is there anything more relaxing than sleeping with your partner?

Image source: giphy.com The study found that sleeping with a regular partner really makes you sleep better.
