Moisture and cold?

Hello, I have been cracking my windows slightly in the winter because I have a thyroid issue and sometimes overheat. I moved my truvada from my bedroom where the window is cracked out into the kitchen which is on the same floor. The rest of the same floor does not get cold from the window being cracked. You wouldn't really know the window is cracked outside of my room. I'm just worried there's moisture circulating on that floor or a subtle temp drop making the medication less effective. No signs of condensation or fogging in my room or in the kitchen .The main floor certainly stays at room temperature. Is this a risk of losing effectiveness? I wouldn't say it's under any extreme conditions. The pills don't look degraded or any different than usual. Just worried because I had an encounter last night Where I need them to be working! I of course take them consistently and go to all of my checkup appointments.
