If you have a daughter or teenage girl who seems more emotional, anxious, irritable or overwhelmed at certain times of the month, you might find yourself wondering:
“Is this just hormones?”
Or perhaps:
“Is something actually wrong?”
The answer isn't always one or the other.
For some girls, hormonal changes throughout puberty and the menstrual cycle can interact with stress, anxiety, sleep, relationships and everyday demands. What you see on the outside might be tears, irritability, withdrawal, arguments or seemingly big reactions to small things. Rather than dismissing these changes as “just hormones”, it can be helpful to become curious about what is happening underneath.
Hormones can influence how we feel
Puberty involves significant hormonal and developmental changes. As girls move through puberty and begin menstruating, fluctuations in hormones can influence mood, energy, sleep and how intensely emotions are experienced. This doesn't mean hormones cause every emotional difficulty.
But for some girls, hormonal changes may make existing vulnerabilities more noticeable. A girl who already experiences anxiety, for example, may notice that her anxiety becomes more intense at particular points in her cycle. She may become more sensitive to social worries, more easily overwhelmed at school or less able to cope with everyday frustrations. This is where parents can sometimes miss the connection.
Look for patterns, not isolated moments
One of the most useful things you can do is start noticing patterns. If your daughter regularly experiences increased anxiety, irritability, tearfulness or emotional overwhelm around a similar time in her menstrual cycle, it may be worth tracking.
You might notice:
Increased anxiety or worrying
More frequent crying
Irritability or anger
Feeling overwhelmed by everyday demands
Increased sensitivity to criticism or conflict
Changes in sleep or energy
Wanting more time alone
Difficulty concentrating
Increased physical complaints
Feeling like small problems are suddenly much bigger
This doesn't mean every difficult day is hormonal. Tracking gathers information, and patterns give us something to work with.
When anxiety and hormones interact
Imagine your daughter has an upcoming assessment at school. Normally, she might feel nervous but manage to complete it.
At another point in her cycle, however, she may already be experiencing changes in sleep, energy and emotional sensitivity. The same assessment suddenly feels enormous. She becomes distressed, snappy, unmotivated and defeated.
You may respond, “You're overreacting. It's just a test.” Leading to more upset and frustration, and suddenly you're both caught in an escalation.
The behaviour might look like the problem, but there may be several things happening at once: anxiety, hormonal changes, stress and an already overloaded nervous system. Understanding that doesn't mean removing expectations, it means changing how we approach the moment.
Respond to the emotion before the behaviour
When your daughter is already highly activated, trying to reason her out of the feeling may not be particularly effective. Instead, start with connection.
Try:
“I can see this feels really overwhelming right now.”
“You seem much more sensitive today. I wonder if your body is needing a bit more support.”
“Let's slow things down before we work out what needs to happen.”
Once she feels understood and has had an opportunity to regulate, you can return to the problem. This is not about letting behaviour slide, it's about recognising that regulation often needs to come before problem-solving.
Don't use hormones to dismiss her experience
There is an important difference between acknowledging hormones and blaming hormones.
Saying: “You're just hormonal” can feel incredibly invalidating, particularly for a teenager who is genuinely struggling.
Instead, try:
“Your body is going through a lot of changes, and I wonder whether that could be making things feel harder at the moment.”
This keeps the conversation open, and it also teaches girls that their physical and emotional experiences are connected, without telling them that their emotions aren't real or important.
Help her become curious about her own cycle
As girls get older, we can gradually shift from parents noticing everything to helping young people understand their own bodies.
Encourage your daughter to notice:
What am I feeling?
What is happening in my body?
Where am I in my cycle?
How have I been sleeping?
What has been happening at school or socially?
What helps me feel more regulated?
This isn't about making her monitor herself constantly; it's about developing body awareness and self-understanding.
For some young women, simply recognising “I tend to feel more emotionally sensitive around this time” can help them respond to themselves with more compassion rather than thinking:
“What's wrong with me?”
When should parents seek support?
Hormonal changes are a normal part of development, but significant or persistent emotional difficulties shouldn't simply be dismissed as hormones. If your daughter is experiencing anxiety, low mood, emotional distress or changes in functioning that are affecting school, friendships, family life or her ability to participate in everyday activities, it's worth seeking professional support.
It can also be helpful to speak with your GP about significant symptoms associated with the menstrual cycle, particularly if they are severe, predictable or consistently interfering with daily life. Psychological and medical support can work alongside each other. Understanding both the emotional and physical picture can provide a much clearer understanding of what your daughter is experiencing.
The goal isn't to fix every emotion
Our girls don't need to learn that difficult emotions are something to fear or eliminate. They need opportunities to understand their bodies, recognise their emotional patterns and develop strategies for coping with change.
So the next time your daughter seems unusually anxious, irritable or overwhelmed, instead of immediately asking:
“What's wrong with her?”
try asking:
“What might her body and nervous system be telling us?”
Sometimes behaviour is the signal. When we become curious about these signals, rather than simply trying to stop the behaviour, we can help girls develop a much stronger understanding of themselves.
