Night shifts don’t have to wreck your hormones — here’s how to support your cycle while working around the clock.
In our previous blog, we explored how night shifts can disrupt your circadian rhythm and ripple out to impact your hormonal and menstrual health. But now it’s time to shift gears — because while you may not be able to avoid night shifts, there are practical steps you can take to support your body.

From protecting your melatonin production to nourishing your nervous system and tracking your cycle, even small, consistent habits can make a meaningful difference. Whether you’re working nights regularly or just occasionally, these tips are designed to help you restore balance, protect your hormones, and stay connected to your cycle — no matter what your schedule looks like.

Night shifts might keep the world running — but they can throw your hormones off track.
Whether you’re a nurse, midwife, paramedic, police officer, or working in hospitality, night shifts are often part of the job. What rarely gets talked about, though, is how working against your body’s natural circadian rhythm can impact everything from metabolism to menstrual health and fertility.

Your body is designed to be awake during the day and asleep at night — with key hormones like cortisol and melatonin regulating that rhythm. Flip this pattern (hello, night shift), and you can disrupt hormone production, ovulation timing, and even egg quality over time.

If you’re a shift worker and noticing changes in your cycle, you’re not imagining things. In this blog, we break down exactly how night shifts affect reproductive health — and what you can do to support your hormones while still doing the work you love.

Your gut does so much more than digest food — and taking care of it is essential for hormone and reproductive health.
In our last blog, we explored the deep connection between gut health and your menstrual cycle. Now, we’re diving into how you can actually support your gut. From the food you eat and the way you manage stress, to your daily movement and environment — each of these plays a powerful role in shaping your microbiome and supporting digestive function.

The gut is a living, breathing ecosystem that responds to every part of how we live. The good news? Small, intentional changes can have a huge ripple effect. Let’s explore the foundations of gut health and how to build a routine that supports your hormones from the inside out.

Want balanced hormones? Start with your gut.
While gut health has become a hot topic in wellness circles, what often gets overlooked is just how deeply it connects to your hormonal and menstrual health. From nutrient absorption and hormone elimination to inflammation and microbiome balance — your gut plays a starring role in keeping your cycle running smoothly.

Whether you're struggling with PMS, period pain, PCOS, or fertility challenges, supporting your gut could be the missing piece. Because when your gut isn’t functioning optimally, your hormones feel it. So if you're working on your hormonal health, don’t forget to show your gut some love — it’s all connected.

Wondering where your period went? You’re not alone.
When your menstrual cycle suddenly disappears, it can feel confusing — even alarming. This is called amenorrhoea, the medical term for absent periods, and it can happen for many reasons. From stress and undereating to thyroid issues, PCOS, or coming off hormonal birth control, your body may be sending a signal that something’s off balance.

Understanding why your cycle has gone missing is key to supporting your health, fertility, and well-being. In this blog, we’ll break down the most common causes of secondary amenorrhoea (when periods stop after previously being regular), how your hormones and lifestyle can affect ovulation, and what steps to take if your cycle hasn’t returned. Because your period is more than just a monthly event — it’s a vital sign of your overall health.

Think BBT predicts ovulation? Think again.
One of the biggest myths about Basal Body Temperature (BBT) tracking is that it can predict ovulation — but in reality, it confirms that ovulation has already occurred. Once your body releases an egg, the hormone progesterone kicks in, warming your body and causing that post-ovulation temperature rise.

So why track BBT if it's all hindsight? Because hindsight is powerful. Whether you're trying to conceive, avoid pregnancy, or simply understand your body better, BBT gives you clear insight into when your fertile window has closed, when your next period is coming, and even offers clues about your hormonal and overall health. At Kyri Cycles, we believe body literacy is life-changing — and BBT is one of the most valuable tools you can use.
