According to these text snippets, research suggests that the menstrual cycle may affect hydration status in women and can be a confounding factor in studies. However, a 2016 study found no significant difference in hydration levels between different phases of the menstrual cycle. Adequate water intake can potentially reduce period-related issues such as acne, cramps, blood clots, low mood, and low energy. Additionally, hydration may have a modifying role in reducing menstrual bleeding duration and pelvic pain. A 2016 study also suggests that hydration status can impact pain sensitivity in women, and immediate reversal may not occur after water intake. Overall, maintaining proper hydration levels is important for women during their menstrual cycle.
