A regular menstrual cycle is extremely important and a vital sign of good health and overall well-being. Nevertheless, women, girls and individuals who menstruate, often contend with debilitating symptoms associated with menstruation, such as fatigue, menstrual cramps, mood fluctuations, disrupted sleep, and headaches. Managing these symptoms pose a significant barrier to the participation in physical activities within schools and can negatively impact on the performance of elite athletes. In this episode, Dr Natalie Brown  in conversation with Dr Sam Blaxland discusses the perceptions and experiences of the menstrual cycle in elite sport and across schools in the UK, and how activity and good nutrition can manage menstrual-related symptoms.
