Research: Black women at higher risk for preterm births during heat waves than white women

Dr. Tracy Prosen is a maternal fetal medicine specialist at Hennepin Healthcare. She said there is a good reason for why preterm births can increase during warmer weather.

“We know that when women are dehydrated, they tend to have more contractions,” said Prosen. “And so, in the summer months, people need to be drinking more water and aren’t always drinking more water, to help keep themselves hydrated.”
