I've always been interested in how closely the brain, hormones, and body are connected.

Many women notice changes in their mood before or during their period. You may feel more emotional, more sensitive to stress, or find that things that usually feel manageable become more difficult.

These changes are not simply in your head.

They can be influenced by real physiological changes happening within the body.

What is serotonin?

Serotonin is a neurotransmitter that helps regulate mood, sleep, emotional balance, and overall wellbeing.

It is often described as the brain's "feel-good" chemical because it plays an important role in helping us feel calm and balanced.

When serotonin activity is lower, we may become more sensitive to stress or find it harder to feel settled.

Serotonin and the menstrual cycle

Hormonal changes throughout the menstrual cycle can affect the way our brain regulates mood, including serotonin activity.

This is one reason emotional changes may become more noticeable before or during a period.

It reflects the close relationship between hormones, the brain, and the nervous system.

Supporting serotonin through daily habits

While we can't control every hormonal change, there are simple daily habits that can support serotonin production and help support emotional balance.

Some ways to support serotonin include:

Spending time outside in natural daylight.
Eating balanced meals with enough protein, which provides the building blocks needed for serotonin production.
Moving your body through gentle exercise, such as walking, yoga, or stretching.
Prioritising regular, restful sleep.
Taking time to relax and reduce stress.
Having someone you feel comfortable talking to when things feel difficult.
