The ovulation period refers to the stage in a woman’s menstrual cycle when her body temperature rises, her appetite increases, and she is energetic. Although this process only takes about a few days, it is very important for women. Because ovulation represents changes in hormone levels in a woman's body, these changes can affect a woman's fertility and health.

During ovulation, a woman's body temperature will rise by about 0.5 to 1 degree Celsius. This process lasts for about a few days and is known as the "ovulation period." During ovulation, women's appetite increases and they may feel hungrier and have more energy.

A woman's ovulation period has an important impact on fertility and health. If women can accurately measure their basal body temperature and engage in appropriate exercise and diet during this period, they can better protect their fertility and health.

A woman's ovulation period is not fixed and is affected by many factors, including climate, diet, exercise, etc. Therefore, women should frequently measure their basal body temperature and adjust their diet and exercise habits according to their body changes.
