Effectiveness of Autogenic Training and deep breathing exercises in college-going girls with Premenstrual syndrome

Premenstrual syndrome (PMS) is the term used to describe a collection of recurring symptoms that start in the late luteal phase of the menstrual cycle (5-7 days prior to menstruation) and end in the follicular phase (2-4 days following menstruation) .Autogenic training is a strategy that allows one to calm their mind and body, which lowers their heart rate, slows their breathing, makes it easier for blood to circulate through their body, and boosts immune system activity . AT is a self-help technique intended to inhibit the body's stressed fight-or-flight reaction.AT promotes balance between the functions of the brain's two hemispheres, as well as the sympathetic and parasympathetic branches of the autonomic nervous system. AT balances the dominant and non-dominant portions of the brain .The AT relaxation technique's mechanism of action is in the relaxation response, as opposed to the stress response, which includes a complex interaction of the endocrine, immunological, neurological, and psychological systems经前期综合征（Premenstrual syndrome, PMS）是用于描述一系列复发性症状的术语，该类症状始发于月经周期的黄体晚期（月经前5~7天），并于卵泡期（月经后2~4天）结束。自主训练（Autogenic training, AT）是一种可平复身心的干预策略，能够降低心率、放缓呼吸、促进全身血液循环并增强免疫系统活性。自主训练作为一种自助技术，旨在抑制机体的应激战斗-逃跑反应，可促进大脑两半球的功能平衡，同时调节自主神经系统交感与副交感分支的功能，平衡大脑优势与非优势区域的活动。自主训练放松技术的作用机制在于触发放松反应，而非应激反应；后者涉及内分泌、免疫、神经及心理系统的复杂交互作用。
