Insomnia during ovulation is mainly due to the fact that most women, during ovulation, suffer from poor health and loss of appetite. During ovulation women’s instincts make them more inclined to express themselves and be more sexually active, as these are the days when they are likely to get pregnant and their bodies are less resistant. Body temperature changes are more pronounced around the time of ovulation in girls, and the safe period can be measured more accurately to determine ovulation based on changes in body temperature. Generally speaking, young girls ovulate under normal circumstances, with lower body temperatures in the early days and higher temperatures after ovulation. Since the menstrual cycle is influenced and controlled by estrogen secreted by the ovaries, it has nothing to do with ovulation. In addition, the phenomenon of increased leukorrhea during ovulation is normal. Insomnia is caused by confusion or anxiety due to emotional tension and other reasons during ovulation, which is mainly manifested as lack of deep sleep and inability to eliminate fatigue and restore physical strength and energy in time, leading to difficulty in falling asleep and forming insomnia.
