Can tracking your menstrual cycle help boost productivity?
An expert Q&A with Clue's Science Team
Many people notice changes in their energy, focus, mood, and motivation throughout their menstrual cycle. These shifts have helped fuel interest in “cycle syncing”—the practice of aligning habits, workouts, work schedules, or self-care routines with hormonal changes across the cycle.
While hormones like estrogen and progesterone can influence how some people feel, there’s no universal “best” phase of the cycle for productivity. Experiences vary widely, and factors like sleep, stress, workload, and overall health also play an important role.
We spoke with Eve Lepage, MSN, RN, to find out more about cycle tracking, productivity, and how to approach cycle awareness without falling into the trap of over-optimization.
Key takeaways:
Cycle syncing is the practice of aligning daily activities with hormonal changes throughout the menstrual cycle
Some people notice shifts in energy, mood, focus, or motivation across different menstrual cycle phases
There’s no universal “most productive” phase of the menstrual cycle
Cycle tracking can support body awareness and help identify personal patterns over time
Cycle awareness should support flexibility and self-understanding—not pressure or perfection
1. Should everyone who menstruates track their cycle?
“I believe cycle tracking can be beneficial for most people who menstruate because it helps build body awareness,” says Eve
The menstrual cycle is often considered a “vital sign” because it reflects how different systems in the body are functioning together. Understanding your personal baseline—like your typical cycle length, bleeding patterns, symptoms, and timing—can make it easier to notice changes or identify potential health concerns early.
“This matters more than people often realize,” Eve explains. “Conditions like endometriosis or polycystic ovary syndrome (PCOS)/PMOS can take years to diagnose. Tracking can help people recognize patterns like painful periods, missed cycles, or unusual bleeding and seek care sooner.”
Tracking can also support more productive conversations with healthcare providers by helping people describe symptoms and changes over time.
There are also practical day-to-day benefits of cycle tracking, including:
Preparing for your period or period-related symptoms
Understanding changes in mood, energy, or sleep
Identifying ovulation timing when trying to conceive
Building awareness of fertile windows
However, Eve notes that cycle tracking alone is not a reliable form of contraception unless it’s used as part of a validated fertility awareness-based method.
2. When is cycle tracking most helpful?
Tracking can be especially useful during times of change or uncertainty, including:
Coming off hormonal birth control
Trying to conceive
Navigating new or worsening symptoms
Experiencing perimenopause
“It’s also helpful for people who are simply curious about patterns,” says Eve. “Tracking can help make recurring changes in mood, focus, sleep, or physical symptoms more visible over time.”
3. How can different menstrual cycle phases affect energy and productivity?
Experiences vary widely, but research suggests there may be some common patterns across the different phases of the menstrual cycle.
Menstrual phase
During the menstrual phase (when bleeding occurs), estrogen and progesterone are at their lowest levels.
“Some people feel lower energy or more inward-focused during this time,” says Eve.
Fatigue, cramps, or disrupted sleep may also make rest feel more necessary for some people.
Follicular phase
During the follicular phase, estrogen begins to rise.
“People often report feeling more motivated, curious, or open to new ideas during this phase,” Eve explains.
As ovulation approaches, some people also notice increased libido or energy.
Ovulatory phase
Around ovulation, estrogen peaks.
“Some people report feeling more confident, social, or communicative during this time,” says Eve, though she emphasizes that these experiences are not universal.
Luteal phase
After ovulation, progesterone rises.
“Progesterone can have a calming or sedative effect for some people, but it can also affect sleep because it increases body temperature,” she explains.
As estrogen and progesterone begin to decline later in the luteal phase, some people experience premenstrual symptoms (PMS), including:
Mood changes
Irritability
Anxiety
Fatigue
Sleep disturbances
For some people, symptoms may be more severe, such as with premenstrual dysphoric disorder (PMDD).
4. Which phase of the menstrual cycle is the most productive?
“There isn’t one universal ‘productivity phase’ that applies to everyone,” says Eve.
Some people feel most energized and mentally sharp during the late follicular or ovulatory phases, while others may prefer quieter or more detail-oriented tasks during the luteal phase.
“It’s important to remember that productivity is influenced by far more than hormones,” she explains. “Sleep, stress, workload, and overall health all play major roles.”
Rather than trying to follow a rigid cycle-syncing framework, she recommends using tracking as a way to better understand your own patterns and needs.
5. How can you adapt your habits to match changing energy levels?
Instead of creating strict rules around cycle syncing, Eve recommends a flexible approach.
That may include:
Prioritizing rest or gentle movement during lower-energy days
Scheduling demanding or collaborative tasks during higher-energy periods
Maintaining consistent sleep, hydration, and nutrition habits
Checking in regularly with your body and symptoms
“Tracking should support awareness, not become another source of pressure,” she says.
6. When is the best time to rest during your cycle?
“Many people feel the need for more rest during the menstrual phase and late luteal phase,” says Eve.
This can be related to cramps, fatigue, PMS symptoms, or changes in sleep quality.
“But the best time to rest is whenever your body signals that you need it,” she adds. “Cycle tracking can simply help people anticipate those moments with more intention.”
7. Can cycle syncing become harmful?
“Yes,” says Eve. “It’s worth being cautious about the idea that we should constantly optimize our productivity around our cycles.”
While cycle awareness can feel empowering, pressure to “sync perfectly” can become another form of self-monitoring or self-judgment.
Lepage also points to broader cultural concerns around menstrual cycle conversations and workplace productivity.
“Framing productivity too closely around the menstrual cycle can unintentionally reinforce stereotypes that people who menstruate are less stable or less capable professionally,” she says. “That’s not supported by science.”
At its best, cycle tracking can help people feel more informed, compassionate, and connected to their bodies—not more restricted by them.
