I've had my Spathiphyllum wallisii for about four months now and I'm still figuring out the watering thing

I've had my Spathiphyllum wallisii for about four months now and I'm still figuring out the watering thing. Everyone says they're forgiving, but mine got pretty droopy last week and I panicked—turns out it was thirsty, not overwatered like I assumed. Now I'm wondering if the dryness in my apartment (cold climate, heating on constantly) is making it need water more often than typical? Has anyone else noticed their peace lilies behaving differently in winter?
