Hydration during Pregnancy

Hydration is extremely important during pregnancy — even more than usual — because your body is:

🔄 Working overtime:

  • Producing extra blood and amniotic fluid

  • Supporting fetal circulation, nutrient delivery, and waste removal

  • Regulating your body temperature (especially important in summer!)

  • Keeping digestion, kidney function, and skin elasticity in balance


💧Dehydration can cause:

Condition Effect
Constipation & hemorrhoids Dehydration slows digestion.
Low amniotic fluid Especially dangerous in later pregnancy.
Urinary tract infections (UTIs) More common when fluid intake is low.
Fatigue, headache, dizziness Even mild dehydration worsens these.
Braxton Hicks contractions Can be triggered or worsened by dehydration.

✅ How much should you drink?

There’s no perfect number for everyone, but a good ballpark is:

約1.5〜2L of fluid per day (including soup, fruit, porridge, and drinks)

If it’s hot, or you’re sweating, or not eating much, aim higher (around 2.5L). Don’t force yourself in one go — sipping throughout the day is more effective and gentler on your stomach.


💡Pro tips for low-appetite or nausea days:

  • Add a little honey or fruit juice to warm water (as you already do!)

  • Try ミルク寒天, cold soups, or orange jelly — hydrating and gentle

  • Fruit with high water content: watermelon, oranges, melon

  • Use a pretty cup or thermos — sounds silly, but it can help mood and habit!


If you’re ever unsure you’re hydrated enough, a simple check is:

💦 Pee should be pale yellow — darker color = drink more!

You’re already doing a lot right (warm honey water, small portions, hydration-focused snacks).
