The menstrual cycle duration varies between women, but the average is 28 days. Though a slight change in this average is considered normal, if one experiences an irregular menstrual cycle for several months, it might signify an underlying health condition that must be diagnosed and promptly treated. In such scenarios, it is advised to seek the help of an ob-gyn and watch out for some unhealthy lifestyle habits that must be changed. Sudden rigorous exercise routine Regular and moderate exercise can improve heart health, mood regulation, and a steady sleep cycle. Moreover, changing your exercise routine and trying a new regime won’t impact your menstrual cycle much. However, problems will arise when one suddenly switches to an extreme exercise/training routine, which can affect one’s menstrual cycle. It is commonly observed in women who start training for marathons or triathlons. Excessive stress Dealing with excessive stress levels for longer periods is another aspect that can impact one’s menstrual cycle. It is because stress leads to the higher production of cortisol, which can interfere with many crucial bodily functions. As a result, there is lower production of estrogen and progesterone. All these factors combined will hamper one’s menstrual cycle. Unhealthy sleeping habits Not maintaining a healthy sleep cycle is a major lifestyle mistake many people commit.
