Doctors say pregnant women need to be cautious during the hot summer weather. Heat exhaustion and heat stroke are especially dangerous for women who are pregnant.
Pregnancy makes body temperature rise, meaning women can be extra uncomfortable when the thermometer rises as well.
When the combination of heat and humidity is in the 90s, staying hydrated is crucial.
Sean Daneshmand, who specializes in treating high-risk pregnancies at the San Diego Perinatal Center, said it's good to know some of the warning signs of heat exhaustion.
"Headache, dizziness, nausea and vomiting, that's one of the big signs," the specialist explained. "You're feeling very tired, you're thirsty, that's time to seek attention."
Daneshmand said when the heat rises, pregnant women should drink eight ounces of water an hour. He advises them also to travel with a cold pack.
