Blog twenty three: Autumn, your cycle, and why you feel tired right now.

Your body knows it's Autumn. Are you listening?

As the season changes here in New Zealand, your body is already adjusting. None of this needs to be consciously adopted. Biology has it covered, quietly running in the background the way it has for every human body long before anyone tried to sell us a morning routine.

Somewhere along the way, many of us stopped trusting it and push through the fatigue, override the pull to rest, and feel vaguely guilty for wanting to slow down. We call it laziness or a lack of discipline when really it's the body doing exactly what it was built to do.

Autumn is an invitation to go inward. There's a lot more behind that than it might sound.

What's actually happening in your body

With shorter days and less sunlight, your circadian rhythm (the internal clock that governs almost everything) naturally shifts. Melatonin production begins earlier in the evening, which is why you feel sleepier sooner. Serotonin can dip when daylight exposure drops, and low vitamin D levels through the cooler months can influence mood and energy, particularly for women who aren't getting outside as often.

So if you feel heavier, less motivated, or more emotional as autumn settles in, there's a real physiological reason for it. Your body is responding to its environment, doing what it's designed to do.

From a nervous system perspective, colder temperatures and lower light are environmental cues. Your nervous system reads those signals and responds by pulling you toward conservation, warmth, and rest. Pushing hard against that usually backfires. You get more dysregulation, slower recovery, and the season still wins in the end.

If you have a menstrual cycle, you'll feel this even more

This is where it gets interesting, and it's something I don't see talked about enough. If you have a cycle, autumn will likely mirror something you already experience every month: the luteal phase. The luteal phase is the second half of your cycle, the week or two before your period arrives. It's a time when your body naturally pulls inward. Energy drops. Tolerance for noise and overstimulation lowers. The need for nourishment, warmth, and rest increases.

Autumn does the same thing, just on a seasonal scale. Both are driven by hormonal and neurological shifts that signal the body to slow, restore, and prepare. If you've ever noticed that autumn feels like a kind of relief, a permission to finally stop performing at full capacity, that's your biology recognising something familiar. Working with it rather than against it changes things. Socially we go inward, we are less inclined to want to go out in the evenings, etc.

What actually helps

None of this requires an overhaul. Small, consistent adjustments across autumn make a genuine difference to how you feel across the whole season.

Nourishment is the obvious place to start. Your body naturally gravitates toward warming, grounding foods at this time of year, and that's worth trusting. Think soups, roasted vegetables, eggs with greens, porridge, and seasonal produce like kūmara, pumpkin, silverbeet, and carrots. Warming herbs like ginger, cinnamon, garlic, and rosemary support digestion and circulation as temperatures drop. Healthy fats from olive oil, seeds, and avocado continue to support hormonal health through the seasonal transition.

Movement matters too, though the approach shifts. Cold mornings lower motivation, and that's completely normal. This isn't the season to push for personal bests. Getting outside early, even briefly, helps anchor your circadian rhythm and keeps serotonin supported. Consistency over intensity, and movement that feels genuinely good rather than punishing, is what your nervous system needs right now.

For your nervous system more broadly, autumn is a good time to wind down earlier, reduce screen exposure before bed so melatonin can do its work, and prioritise connection. Shared meals. A walk with someone you enjoy. Conversations that don't happen over a screen. Your nervous system recovers through safety and real connection, and both matter more when the days are shorter and the world feels a little quieter.

A note on mindset, because it's often where we trip ourselves up. Slowing down is part of the design. Adjusting your pace across autumn means working alongside your body instead of dragging it behind you through the season.

A question worth sitting with

When did you last actually listen to what your body was asking for, rather than what your schedule demanded of it?

Autumn has a way of making that question harder to ignore. The light changes, the pace of nature changes, and something in us recognises it even when we're trying to push through.

You don't have to do a complete life overhaul. You just have to be willing to notice. Start there.

If you're ready to build habits that actually work with your body and your life, rather than against them, I'd love to support you.
