The Summer Hormone Shift: What Women Need to Know About Seasonal Changes and Mood
Let me ask you something — have you ever felt like your mood or energy just isn’t quite the same when summer hits? Maybe your appetite shifts too? You’re definitely not imagining things.
I’ve noticed this myself and hear it a lot from the women I work with: our hormones really do dance to the rhythm of the seasons. For women, those changes can sometimes feel especially clear — even if they’re subtle.
So, what’s actually shifting inside?
Cortisol — your stress hormone — gets a little help from the sun
Cortisol is kind of like your body’s built-in alarm clock, helping you manage energy and stress. In summer, the extra sunlight can nudge your cortisol levels up earlier in the day — which can mean waking up feeling sharper and more alert.
But here’s the catch: too much heat or stress can flip the script, making you feel drained or anxious instead. That’s why balancing your activity with some good rest is so important.
Melatonin — the sleep hormone — takes a backseat
Longer days mean less darkness, and less darkness tells your brain to slow down melatonin production. That’s why falling asleep or getting deep rest can feel trickier in summer.
Good sleep is key for keeping all your hormones in harmony, plus it affects your mood and energy too. I’ve found that creating a calming evening routine and keeping my bedroom cool and dark really helps me get better rest during these bright months.
Serotonin — the “feel-good” neurotransmitter — thrives in sunshine
Sunlight is like a natural boost for serotonin — the brain chemical that lifts your mood, helps regulate appetite, and keeps sleep on track.
That’s probably why so many of us feel happier when we spend time outside in summer. But if you’re stuck indoors or skipping outdoor time, you might miss out on this natural mood lift.
Estrogen and progesterone — your key female hormones — respond too
Seasonal shifts can also influence these hormones, which affect your menstrual cycle, mood, and even your skin.
Some women notice their cycles shift a bit with the seasons or feel changes in energy and emotional sensitivity. Staying tuned in to these subtle shifts helps you work with your body instead of against it.
So, how can you support your hormones as summer rolls in?
Get outside — but pick your moments. Morning or evening sunshine can boost serotonin without overheating you (trust me, your body will thank you).
Prioritize sleep. I swear by blackout curtains and sometimes an eye mask to keep the room dark and cozy, helping melatonin do its job.
Keep stress in check with gentle moves like yoga, meditation, or just some mindful breathing.
Eat in a way that supports your hormones — colorful veggies, healthy fats, and plenty of water.
And most importantly: listen to your body. Notice what feels different and adjust your routine a bit.
Summer is a season of growth, light, and new energy — your hormones are just helping you tune in and thrive. With a little care and attention, you can ride this wave feeling balanced and joyful all season long.
