Have you ever found yourself crying over a cute puppy video, or feeling sudden, blazing anger because someone chewed too loudly? You’re not alone; it happens to most of us!
Nearly 90% of women experience some form of PMS (Premenstrual Syndrome), with mood fluctuations being one of the top complaints. It isn't "all in your head," and it certainly isn't a sign of weakness. It is a sign that your body is going through a massive chemical shift.
Let’s talk about why these emotional changes during periods happen and, more importantly, how you can handle them without feeling like you’re losing control.
Why Do I Experience Emotional Breakdown During Period?
Mood swings during periods are driven by the natural rise and fall of hormones that regulate your mood.
Estrogen-Serotonin Levels: During the initial stage of your menstrual cycle, Estrogen levels are at their peak. This hormone supports the production of Serotonin, a neurotransmitter in the brain responsible for maintaining emotional stability and a sense of well-being.
Pre-Menstrual Shift: In the days leading up to your period, if pregnancy has not occurred, your Estrogen and Progesterone levels decrease significantly.
Neurochemical Impact: As Estrogen levels decline, Serotonin levels often follow. This reduction can make you more sensitive to external stressors, leading to symptoms of irritability, anxiety, or low mood.
Role of Cortisol: Simultaneously, fluctuations in these reproductive hormones can lead to a slight increase in Cortisol, the body’s primary stress hormone. The combination of reduced Serotonin and increased Cortisol is the physiological trigger for the emotional vulnerability experienced during this phase.
While mild emotional breakdown during period days is common, they should not interfere with your daily life or mental health. If you find these emotional shifts difficult to manage, it is important to discuss with a gynaecologist. Personalised care can help you manage your cycle in a healthy way.
PMS vs. PMDD: When to Seek Help
It is common to feel more sensitive while menstruating, but there is a clear medical line between "common" symptoms and a "debilitating" condition.
PMS (Premenstrual Syndrome): This is a group of physical and emotional symptoms that occur in the 1–2 weeks before your period. While it can be uncomfortable, it generally does not stop you from carrying out your daily responsibilities.
PMDD (Premenstrual Dysphoric Disorder): This is a severe, chronic medical condition that is much more intense than typical PMS. It involves extreme mood shifts that can significantly disrupt your work, social life, and relationships.
Feature | Premenstrual Syndrome (PMS) | Premenstrual Dysphoric Disorder (PMDD) |
Intensity | Mild to Moderate | Severe and Debilitating |
Impact | You can usually manage your daily tasks. | It interferes with work, school, or relationships. |
Emotional State | Irritable or slightly teary. | Feelings of hopelessness, panic, or intense rage. |
Timing | Relieves shortly after bleeding starts. | Symptoms are severe enough to require clinical intervention. |
If you feel like the column on the right describes you, please speak to a gynaecologist. You don't have to suffer with this; PMDD is highly treatable with expert guidance.
Can Emotional Stress Cause Period Delays?
Yes, indeed! Stress is one of the reasons for delayed periods. See, your brain and your reproductive system are in constant communication via the Hypothalamic-Pituitary-Ovarian (HPO) axis.
When you are under high emotional stress, your body prioritises survival over reproduction. High levels of Cortisol can signal the brain to pause the hormones required for ovulation. If ovulation is delayed or doesn't happen, your period will be late or may skip a month entirely.
It is medically normal for a cycle to fluctuate by a few days occasionally. However, if your period is delayed by more than 7 to 10 days beyond your expected date, it is time to consult a gynaecologist. This helps us rule out other factors like pregnancy, thyroid imbalances, or PCOD and ensures your reproductive health is on track.
How Can I Stop Mood Swings Naturally: Mood Swings Remedies
You don't just have to sit there and suffer. There are science-backed ways to cushion the fall of those hormones.
1. Nutritional Support
Since your happy chemicals are low, eat foods that boost them.
Complex Carbs: Foods like oats and whole grains help stabilise blood sugar and support Serotonin production.
Dark Chocolate: A small piece (70% cocoa) can actually lift your mood.
Magnesium& Vitamin B6: Found in spinach, almonds, and bananas, these are clinically shown to reduce premenstrual anxiety and muscle tension.
2. Move, Even if You Don't Want To
Especially around periods, the couch looks the comfiest place. But light exercise is whatreally helps. You can go on a walk or do some stretches to relax your body. Doing low-impact movements releases Endorphins, which act as natural mood elevators and painkillers.
3. Prioritise Sleep
Fatigue lowers your threshold for emotional regulation. Get 8 hours of sleep, especially in the "Luteal Phase" (the week before your period).
4. Clinical Supplements
In some cases, taking Calcium or Vitamin D3 supplements helps, as they can reduce the severity of PMS symptoms.
However, please don’t self-medicate. Ask your gynaecologist before taking supplements to ensure you aren’t unknowingly harming your body.
Conclusion: Be Kind to Your Mind
If you find yourself crying in the bathroom or snapping at a loved one, take a deep breath. There’s nothing “wrong” with you. You are simply responding to biology.
However, you shouldn't have to suffer in silence. If your emotional changes during periods are hurting you and your relationships or work, it’s time to build your support team. A simple discussion with a gynaecologist can open doors to supplements or treatments that make that time of the month feel just like any other week.
Frequently Asked Questions (FAQs)
Q: Why do I feel depressed immediately before my period?
This is primarily due to the sudden drop in estrogen and serotonin levels. Since serotonin regulates mood, a drop can trigger temporary feelings of sadness or depression.
Q: Can emotional stress cause period delays?
Yes. Mental stress raises cortisol levels, which can suppress the hormones needed for ovulation. This can lead to a late period or a missed cycle.
Q: Is it normal to have an emotional breakdown during my period?
Occasional crying is normal. However, if you feel hopeless, out of control, or unable to function, it may be a sign of PMDD. Please consult a doctor if this happens regularly.
4. Do periods get worse with age?
They can. As women approach their late 30s and 40s (perimenopause), hormone fluctuations can become more erratic, which can sometimes make mood swings more intense.
5. Can exercise really help with emotional stress during periods?
Absolutely. Low-impact exercise like yoga or swimming boosts endorphins and reduces cortisol, acting as a natural stress-buster.
