Some days the plunge feels like bliss. Other days you can barely last 30 seconds. It’s not in your head, it’s in your cycle.
Oestrogen and progesterone shift your core temperature, your stress response and your cold tolerance across the month. Follicular phase (first half)? You’ll likely feel strong, recover fast, want to stay in longer. Luteal phase (second half, especially the week before your period)? Core temp runs higher, nervous system is already working harder, and the cold hits twice as hard.
Track it. Honour it. Shorter plunges in your luteal week aren’t quitting, they’re smart.
