Women often experience increased sensitivity and emotional upheaval during their premenstrual syndrome (PMS).

Understanding the underlying reasons for these emotional changes can provide insights into the complexity of women’s health and mood fluctuations during this period.

Understanding PMS

Premenstrual syndrome (PMS) refers to a range of physical and emotional symptoms that many women experience in the days leading up to their menstruation.

Common symptoms include irritability, mood swings, and increased emotional sensitivity. But what causes these changes?

Hormonal Changes

One of the primary factors contributing to emotional fluctuations during PMS is hormonal changes. After ovulation, the levels of estrogen and progesterone decrease significantly.

Impact of Estrogen and Progesterone

Estrogen and progesterone are pivotal hormones that play a crucial role in regulating mood and emotional stability. The rapid decline of these hormones can impact neurotransmitter activity in the brain, leading to increased sensitivity and mood swings in women. This hormonal shift is the backbone of many symptoms associated with PMS.

Factors Affecting Mood in PMS

While hormonal changes set the stage for emotional upheaval, several additional factors can exacerbate mood swings during PMS.

Reduced Serotonin Levels

Serotonin, often referred to as the "feel-good" chemical in the body, is instrumental in regulating mood, appetite, and sleep cycles.

The Connection Between Low Serotonin and Mood

When serotonin levels dip, it can lead to feelings of sadness and irritability, even without any external triggers. In women experiencing PMS, the hormonal fluctuations can lead to decreased serotonin production, contributing to increased emotional instability.

Poor Sleep Quality

Sleep quality is another critical factor influencing mood. An insufficient amount of sleep or disrupted sleep patterns can worsen emotional sensitivity.

How Sleep Affects Mood

Lower serotonin levels can make it difficult to achieve restful sleep. Consequently, a cycle is established where fatigue becomes a contributor to irritability and emotional strain. Women may find themselves feeling exhausted and mentally drained during PMS, which can manifest as frustration or heightened emotional sensitivity.

Changes in Appetite

Hormonal changes can also lead to a shift in appetite, often resulting in cravings for sugar or high-carbohydrate foods.

The Effects of Dietary Choices

While these foods may provide a temporary boost in serotonin levels, they often lead to a crash afterward, resulting in deeper feelings of sadness or depression. Research suggests that indulging in sugary snacks might offer momentary comfort but can worsen overall mood once their effects wane. This fleeting happiness followed by a slump can contribute to emotional turbulence.

Lack of Physical Activity

Many PMS symptoms, such as bloating and pain, can discourage women from engaging in physical activity.

The Role of Exercise in Mood Regulation

When women experience discomfort, they may opt to rest instead of participating in physical activity like exercising or going for a walk. This lack of movement can decrease endorphin levels—natural mood lifters—possibly leading to a lower mood and increased feelings of sadness or depression during PMS.


Understanding why women experience heightened emotions and sensitivity during PMS involves recognizing the interplay of hormonal shifts, serotonin levels, sleep quality, dietary habits, and physical activity.

While the complexity of PMS can be overwhelming, acknowledging these factors can lead to more effective coping strategies and greater empathy for those experiencing these emotional challenges.
