What is cycle syncing?
Cycle syncing means noticing how your body and mind change across the month and adjusting food, movement, work and rest to suit. It is a way of planning with your natural rhythm instead of pushing against it.
Hormone changes across the cycle are well established. Whether matching your habits to each phase improves results is still being studied, so this site presents ideas as gentle experiments you can test on yourself.

Frequently asked questions
Do all cycles last 28 days?
No. Many cycles fall between 21 and 35 days. The 28-day cycle is a common textbook example, and your own length may be shorter or longer.
Can my phases change from month to month?
Yes. Stress, illness, travel, sleep and life stage can shift your cycle, so treat the dates as estimates.
Where should I start?
Start with the Tracker and the guide for your current phase, then try one small change for a few cycles.
