黄体期のセルフケアのヒント
Magnesium
Take 200–400 mg/day to ease cramps, mood swings, and sleep issues. Dark chocolate counts too.
Reduce salt
Cut back on sodium to minimize bloating and water retention. Avoid processed foods in the last week.
Exercise
Moderate activity like walking, yoga, or swimming can reduce PMS severity by up to 30%.
Sleep
Aim for 8+ hours. Progesterone makes you sleepier — lean into it instead of fighting fatigue.

よくある質問
Why does PMS happen?
PMS is caused by hormonal changes during the luteal phase — the time between ovulation and your period. After ovulation, progesterone rises sharply and then drops before menstruation. This hormonal shift, along with changes in serotonin levels, can trigger mood swings, bloating, fatigue, breast tenderness, and cravings.
What are the worst PMS symptoms?
The most commonly reported severe symptoms include mood swings, irritability, anxiety, bloating, breast tenderness, fatigue, headaches, and food cravings. About 3–8% of women experience PMDD (Premenstrual Dysphoric Disorder), a severe form that significantly impacts daily life and may require medical treatment.
What supplements help with PMS?
Research supports magnesium (200–400 mg/day) for cramps and mood, calcium (1,000–1,200 mg/day) for mood and bloating, vitamin B6 (50–100 mg/day) for mood and irritability, and omega-3 fatty acids for inflammation. Chasteberry (Vitex) may also help regulate hormonal balance. Always consult your doctor before starting supplements.
When should I see a doctor about PMS?
See a doctor if PMS symptoms significantly interfere with your daily life, work, or relationships; if symptoms are getting progressively worse; if you experience severe depression or anxiety before your period; or if over-the-counter remedies and lifestyle changes aren't helping. You may have PMDD, which is treatable.
