Some books have written that the full moon night can easily cause people to have emotional fluctuations, which is not conducive to the activity of sperm and eggs. There is no scientific basis for this statement. On full-moon nights, people usually take longer to feel sleepy, and even if they finally fall asleep, their sleep is shallow. The reason has nothing to do with the moon's brilliance or gravity. Researchers believe that this phenomenon is a kind of "lunar clock" that depends on the period of the moon's cycle. Scientists speculate that sleeping less soundly on full-moon nights helped our ancestors avoid wild animals that hunted by moonlight. In fact, in a normal human body, the composition of body fluids fluctuates within a very small range. It is an important factor in maintaining a relatively stable internal environment of the human body, including water, electrolytes (mainly sodium, potassium, chloride, and bicarbonate ions), etc. Water is necessary to maintain a relatively constant body fluid volume. The amount of water excreted and consumed daily must be equal to maintain the balance of water metabolism. Water is excreted mainly through urine, exhalation from the lungs, and evaporation from the skin. If a person can eat normally and has no gastrointestinal or kidney diseases, the intake and excretion of electrolytes such as potassium, sodium, and chloride will be relatively balanced. People's emotions change cyclically every month, which is called physiological rhythm. One cycle is 28 days, divided into high and low periods. Pregnancy should be chosen during the climax period when both parties are energetic, emotionally stable and in a good mood, and also 1 to 2 days before ovulation. In this way, the egg just released is the freshest and most energetic. If it can be fertilized immediately, it can avoid various interferences from the external environment, form an excellent fertilized egg, and give birth to a healthy baby. |
