Notice that on some days your eyes dry out faster? You sweat more profusely? Your nose is more congested? You can reach higher notes when you sing? Your breath is a bit odorous? Or that you’re lubricating more easily during physical intimacy?
One key reason for these changes is your body’s changing level of hormones throughout your menstrual cycle. As hormones rise and fall, they can impact how moist or dry certain areas get.
Here’s a Hormonology Cheat Sheet that gives you a quick rundown of what kind of moisture level you can expect in your body–and why:
Your EYES are drier in your Week 2:
High estrogen reduces tear production
Your MOUTH is drier in your Week 1 & Week 4:
Low estrogen reduces saliva production, which can lead to bad breath
Your NOSE is more congested in your Week 2:
High estrogen increases mucus production in nasal passages
Your VOCAL CORDS are moister in your Week 2:
High estrogen increases lubrication of vocal cord tissue, which helps you reach higher notes when singing
You SWEAT more in your Week 3 and Week 4:
Higher progesterone increases your core body temperature slightly, which triggers greater perspiration
You have more VAGINAL lubrication in your Week 2:
High estrogen increases vaginal fluids during arousal, making physical intimacy more comfortable
