Is it better to sleep when you are sad?

  Just sleep well, forget all your troubles, and wake up the next day is a brand new day. This is a phrase that many people often use to comfort others, but does sleep really have such an effect?
  From a psychological point of view, the effect of doing so is just the opposite. Because if people go to sleep with pain and troubles, then during deep sleep, the brain will directly convert these painful memories from short-term memory to long-term memory. That is to say, this matter will accompany you for a longer time, and it will be difficult to forget. Falling asleep with emotions is also prone to nightmares and insomnia, which not only easily leads to lack of sleep, but also causes a certain degree of mental stimulation.
  Sleeping with emotions may aggravate bad emotions, such as emotional irritability, leading to increased psychological pressure. Over time, it may cause some mental illnesses including anxiety, depression, and schizophrenia. Failure to adjust emotions in time may also stimulate the central nervous system of the brain and have a certain impact on the organs in the body.

  ”Snow White”, “White Enchantress”, “Light Snow”… Now there are many different varieties of white strawberries on the market. They are all white, completely subverting people’s perception of strawberries. There are rumors that “white strawberry is a genetically modified fruit”, which makes some people shy away from it. So what is the truth?
  In fact, the reason why the appearance of strawberries is red is because strawberry cells contain a lot of anthocyanins. However, strawberry is a berry plant that is prone to genetic variation. When strawberry cells are cultured to a certain extent, the content of anthocyanins decreases, and natural variation occurs. strawberry.
  All over the world, hybrid breeding has always been the main means of strawberry variety breeding. There are many reasons for the variation in the appearance of strawberries, both external and internal. White strawberries are the result of genetic mutations during cultivation, and have nothing to do with artificial genetic modification.

  The earliest recorded human nose-picking behavior appeared in 4000 BC. On the murals of ancient Egypt, you can see the picture of picking the nose. Why from ancient times to the present, some people have a soft spot for the seemingly indecent thing of picking their noses?
  Physiologically speaking, on the one hand, the nasal cavity serves as a breathing pathway. When there is a foreign body in the nasal cavity, normal breathing will be affected to a certain extent, and a sense of insecurity will also arise psychologically, and removing the foreign body can make people feel smooth breathing. On the other hand, there are very rich blood vessels and nerves distributed under the nasal mucosa. Picking the nostrils is similar to tickling the nasal cavity, which will make people feel comfortable. So this seemingly indecent behavior can indeed make the body and mind feel happy and satisfied.
  It is worth noting that if you often involuntarily pick your nose, it is likely to be a compulsive behavior in an anxious state. When the perpetrator is unable to cope with current or future events, he may adopt this method to escape the status quo and ease his emotions. If such unconscious compulsive behavior occurs, self-adjustment should be made in time, and the help of a psychologist can be sought if necessary.

  If you like to drink tea, you should have noticed that after cooling the brewed tea, a thin tea film sometimes forms on the surface of the tea. When the film is touched with a spoon, it breaks apart like an ice floe and takes on a rainbow of colors when illuminated. So what exactly is this “tea film”?
  In 1994, two chemists in the Chemistry Department of Imperial College of Technology noticed the “tea film phenomenon”. Through the analysis of sophisticated instruments such as scanning electron microscope and mass spectrometer, they found that the tea film is not a simple “oil film”, but formed by the interaction of air, tea polyphenols and calcium carbonate ions on the surface of tea water – insoluble carbon Tiny particles of acid salts and hydroxides attach to the surface of organic matter, thus forming this film.
  Calcium ions and bicarbonate ions in water are the key factors to induce the formation of tea film, and the tea film will only appear when both exist at the same time.
