Cycle, Heat, and What to Wear in Each Phase
July 2, 2026 · Alo Editorial · 3 MIN READ
Your body temperature changes by roughly half a degree across the menstrual cycle, and this interacts with fabric choices in ways that are worth knowing.
Resting core temperature shifts by about half a degree across a menstrual cycle. That is small, but it sits exactly on the boundary between feeling comfortable and feeling too warm in a given fabric. Below: what to look for, what to skip, and the checks that catch a bad fit early.
Menstrual phase: heat production peaks
Core temperature is highest during menstruation, and many people feel warmer during this phase. A mid-weight knit that is comfortable in week two can feel warm in week one.
- Prefer lightweight, unbrushed knits in this phase
- Expect more perspiration than usual at the same effort level
- Increase the rotation rather than fighting the heat with a lighter fabric
Follicular phase: the easiest phase to practise
Core temperature is lowest here and many people report higher energy and better recovery. This is when most people can handle the most demanding practice, and it is a reasonable time to introduce something new.
Ovulatory phase: a common energy peak
Many people experience a short peak in energy and confidence here. It is worth not overloading the calendar with your hardest sessions if the week after is lower.
Luteal phase: heat tolerance drops
Core temperature rises through this phase and many people feel colder, particularly on the limbs. This is where a heavier or brushed fabric stops being excessive and becomes correct.
- Add a mid layer for practice if you feel cold in the second half
- Long sleeves and full-length legs help more than a heavier base layer
- Expect lower energy; reduce intensity rather than fighting it
- Warm feet and hands are the most common complaint
The same garment can be right in one week and wrong in the next. That is the fabric behaving correctly and your body doing what it does.
Practical adjustments
- 01Keep both a lightweight and a mid-weight legging rather than one compromise
- 02Use layers you can add and remove rather than choosing one heavier garment
- 03Adjust hydration; fluid needs vary across the cycle
- 04Reduce intensity in the lower-energy phases rather than dropping practice entirely
What to check before you buy for understanding your cycle and
Two pieces can look identical on the hanger and behave differently in understanding your cycle and. The checks below are the ones that catch it early. Black Supernatural Sweater Tank is the piece we would test them against first.
- Reach overhead: the armhole should not pull the hem up with it.
- Side bend in a mirror — a low cut gaps, a high cut restricts the shoulder.
- The hem should stay put in a forward fold without constant tugging.
What does not change
Consistency does not require identical conditions. The practice that survives a difficult week is the one you shorten, not the one you skip. A twenty-minute session in the low-energy phase maintains the habit better than a cancelled intention to practise fully next week.
