It will answer the nagging questions you’ve had about why some days you feel happy or sad, energized or tired, talkative or quiet—without a clear reason why.
It will enable you to understand yourself, your motivations, your romantic desires and your health in a way you never could before.
It will help you make every day better.
That’s because Hormonology shows you how the ups and downs of the hormones in your monthly menstrual cycle impact your mood, health and behavior every day—and how to use this information to get the most out of hormonal benefits and overcome hormonal challenges.
Did You Know…
• On Day 8 of your monthly cycle: You’re more upbeat and energetic and sleep more soundly thanks to rising estrogen. However, you’re also more easily stressed due to the same hormone triggering higher arousal in the brain. So, it’s key to have stress-busters (such as calming chamomile tea) ready to use in case tension rises.
• On Day 20 of your monthly cycle: Rising progesterone is sapping your energy and revving your appetite. However, this same hormone also prompts up to 30% greater fat-burn during aerobic exercise—which means working out not only counters hormone-related fatigue and revs your pep (by boosting circulation and triggering the release of feel-good endorphins), it also helps you burn off excess calories.
• On Day 25 of your monthly cycle: Plunging estrogen can trigger moodiness and worsen sleep. However, this same estrogen drop also makes you faster at spotting potential dangers, such as a car veering into your path, keeping you safer.
How Hormonology Works
Hormonology uses thousands of hormone studies to show you how your hormones impact virtually every aspect of your day—including your mood, energy, memory, love life, spending habits, sleep quality, food cravings and health.
It shows you how these hormonal effects repeat the same way cycle after cycle—so you can predict what your day will be like tomorrow, next week, a month or even a year from now.
Hormonology delivers this hormone information with a suite of useful tools, including Hormone Horoscope menstrual cycle tracker apps, Hormonology Guides and videos. You pick the tools that work best for you, then use them to learn all the ways you’re being impacted your monthly hormones—and how to maximize their benefits and overcome their challenges.
The woman behind
Hormonology was created by Gabrielle Lichterman, women’s health journalist and author of 28 Days: What Your Cycle Reveals about Your Love Life, Moods and Potential.
In 1999, Gabrielle made a breakthrough discovery: She realized she could organize and connect the complicated jumble of thousands of studies describing how hormones impact women and plug them into every day of a menstrual cycle calendar.
The result was a new type of menstrual cycle calendar that enabled women to do something never before possible: Women would be able to easily predict what their moods, health and behavior would be based solely on where they were in their monthly cycle.
By arming women with this knowledge, Gabrielle was confident this would make their lives better. That’s because women could now plan their day, week and month around the predictable ebbs and flows in mood, energy, memory and more. And they could anticipate the hormonal benefits and challenges that lie ahead.
Since making her discovery, Gabrielle has pioneered the practice of applying hormone research to everyday life and spearheaded the movement for women to live in sync with their menstrual cycles. She created Hormonology as the way to do this.
Her mission is to share Hormonology with others to ensure that all future generations of girls and women have this critical hormone information from their very cycle.
