YOUR HORMONAL MAP: Estrogen, progesterone, and testosterone are being pumped out by your ovaries, following a more predictable pattern than during your teens.
WHAT IT MEANS FOR YOU: Lots of energy, a revved-up libido, killer cognitive skills, and less-severe mood swings.
WHAT YOUR PERIODS ARE LIKE: Pretty regular, which means less-intense cramps.
MAKE IT BETTER: To prevent cramps, take up to four ibuprofen daily on the three days before your period. Ibuprofen (such as Advil or Motrin) prevents the buildup of prostaglandins, hormone-like chemicals that cause cramp pain. Or try prostaglandin-blocking omega-3 fatty acids (found in fish, flaxseeds, and walnuts), or apply heat to the cramped area with a heating pad or hot-water bottle.
HEALTH ALERT: High levels of estrogen keep arteries flexible and plaque-free, but this hormone declines with age, so you become more vulnerable to heart disease. Follow these steps to stave off this deadly condition:
Continue (or start) an exercise regimen. After 20 minutes of working out, your body begins burning off triglycerides.
Check your birth-control pills. If your LDL (i.e., “bad”) cholesterol or triglycerides are high, your Pill could be to blame. Ask your doctor if you need to switch.
