Safe to drink cooling water during pregnancy?

You mean cooling water like 3 leg water? If its that, it's not advisable. According to TMC, When we are pregnant, we are suppose to keep our womb and body warm. That's why some pregnant ladies will choose to drink Red date longan tea, ginger tea etc. (Warm doesn't mean heaty, heaty like fried food, feverish feeling) Cooling water like the 3 leg brand is consider "cold" to our womb. So the best way to stay cool, is to flush lots of normal water to chase the heatiness away, eat fruits, stay indoor more often as the weather is really very hot recently.
