In case you haven’t noticed: it’s officially summer. 

‘Tis the season for scorching hot temperatures, boob sweat, and day party fun—and it’s also the time of the year where your hormones may start to ricochet. That’s right: whether you’re menstruating or menopausal, your endocrine system can be affected by the seasons—and in summer time, your hormones are likely to be having a time. 

Shocked at this brand new info? Fully aware and desperate for solutions? Either way, you’ve come to the right place: we’ve got the run down and a few must-know tips that’ll make the season of sun a bit more bearable.


How can heat affect my hormones? And why? 

Recent studies have found that just like the weather itself, your hormone levels can fluctuate cyclically throughout the year. Some specific hormones have a more pronounced reaction to the summer season: ahem, cortisol. 

Cortisol, the hormone in charge of the body’s stress responses, was found in a 2019 salivary analysis to hit peak levels during June, July, and August. The reason? Excessive heat creates stress in the body! Blood flow is rapidly redirected to the skin to keep you cool, your body loses water and salt rapidly because you’re sweating more, and dehydration is an increasing threat. Folks also tend to be out and about more during the summer, and if that level of activity isn’t typical for you, that can be physically stressful—even if you’re having fun! 

Other hormones that peak in the summer season include those hosted in the pituitary gland, which rein over your reproductive functions, lactation, and metabolism


How do I know if my hormones are being affected by the weather? 

“When you know, you know” probably isn’t the most satisfying response here, but your body will truly give you the answers you’re looking for. Here are some symptoms you might notice if you’re experiencing a hormonal imbalance and/or prolonged spike in cortisol levels: 

  • Bloating, particularly around the face
  • Rapid weight gain
  • Mood swings or irritability 
  • Increased thirst 
  • Increased frequency of urination
  • High blood pressure
  • Muscle weakness 

If you’re experiencing any of these during the summer time, it’s likely a sign that your endocrine system is reacting to the hotter weather. It might be time to call in the calvary—and by that, we mean your primary care physician or endocrine specialist. 


I’m PMSing. What should I do? 

Experiencing premenstrual syndrome during the summertime is no joke—but we’ve got some keys to lowering your cortisol, and keeping your hormones in check: 

Stay Hydrated

We know! You’ve heard it before—but we’re very serious. During the last week of your luteal phase (when PMS occurs), your body fluid regulation varies. And in the summer months, you’re already sweating more. Remember how your body works in overdrive in hotter temps to stay cool? Give it a hand by hitting your water intake goal every single day. 

Get that Lemon (Balm) Aid

There are many natural ingredients that fight cortisol production, but lemon balm is a scientifically-proven anti-stress superhero. The herb’s uses for anxiousness and mood regulation date back over 2000 years—and you can find it in our PMS relief vitamins.  


Embrace Vitamin D

Vitamin D has been found to block the enzymes that create cortisol in the body. And while it might now seem counterproductive to sunbathe to decrease stress—but there’s plenty of other ways to get Vitamin D. Lucky enough to have a sunroom or large window? Spend some time there and soak in the sun’s rays while staying out of the heat (don’t forget your SPF!). While you’re at it, consider taking a supplement or adding these Vitamin D-rich foods to your summer diet. Salmon’s on the list—all nigiri welcome!

I’m experiencing menopause. What should I do?

If you’re going through menopause, you’re no stranger to hormonal fluctuations. But going through those changes, and the symptoms that come with them, in the summer heat? Not exactly a walk in the park. Hot flashes in 90 degree weather is the stuff of our nightmares. Here are some pointers: 


Keep Cool

Hot environments can trigger hot flashes, which are an already common occurrence for 75% of perimenopausal women. So, let’s chill this summer — literally. Crank your central air, keep multiple fans running, grab a cooling blanket, have ice packs ready, and tote around a handy portable fan, if it helps. Don’t assume one source of cool air is enough! If you’re going to the beach or the park, bring an umbrella to create your own shade. And know when to head back inside. Shoo any twinge of embarrassment away, if it comes up — you’re doing what you need to regulate your body. 

Add in Low Impact Exercise

If you want to decrease your cortisol, stay active, and enjoy the summer weather, make sure any exercise that you engage in is low-impact. And no, that’s not just yoga! You can take a reformer Pilates class, go for a moderate incline walk with a friend, or even swim a few laps. 

Consider Medication or Supplement Support

Menopause symptoms can be debilitating enough without the additional heat. So, in the summer season, you might want to consider intervention through medication subscribed by your PCP. If you’re looking for a more natural, hormone-free option, try MENO Menopause Relief



This celebrated season of fun can turn into the opposite when you’re dealing with fluctuating hormones. But you don’t have to suffer in silence! Reach out to your medical team, listen to your body’s signals, and do your best to stay cool as we head into the hottest months of the year.
