In particular , there ’s grounds that woman who experience hyperthermia in the first six to eight weeks of gestation are at in high spirits risk of having babies with defect of the brain or spinal electric cord ( known as nervous metro defects ) , such asspina bifida , Aftab said .
Women may develop hyperthermia from a fever , exposure to excessively hot temperature outdoors or even a cutpurse in a hot tub . Indeed , theMayo Clinic adviseswomen to spend no more than 10 minutes in a hot tub due to the risk of hyperthermia .

However , Aftab note that the jeopardy of nascency defects tied to hyperthermy is mostly limited to the first eight weeks of pregnancy . In other words , a spike in body temperature that occur after eight weeks of maternity is unlikely to increase the risk of infection of birthing defects .
And even if a cleaning lady does know hyperthermia in other maternity , the risk of neural tube defects is still downcast , Aftab said . ( There are about 1,500 babies born with spina bifida in the United States each year — a charge per unit of about 3 cases per 10,000 nascence , according to theCenters for Disease Control and Prevention . )
Dehydration risks
Women ’s soundbox undergo a quite a little ofchanges in gestation , including change in the way their bodies handle fluids and assure their temperature . As a solvent , they may become dehydrated a little more easily , or may be more likely to show symptoms of desiccation , than they would be if they were n’t pregnant , Aftab enjoin .
Symptoms of evaporation can admit vertigo or dizziness , which can be hazardous for significant women if these symptoms have them to fall , Aftab said . ( Falls during the late 2d and early third trimester can be harmful to both the mother and the baby , leading to complication such as a red ink of amniotic fluid , harmonize to theMayo Clinic . )
In addition , dehydration have the mentality to bring out a hormone call Pitressin ( also call antidiuretic hormone ) , which triggers thirst . But this hormone is similar tooxytocin , the hormone involved in energize uterine contraction , Aftab said . As a result , dehydration in the third trimester may trigger intermittent uterine contractions , because vasopressin act likewise to oxytocin , Aftab said .
These contraction , which are not " honest " labor , can often be treated with rehydration , according to theUniversity of Texas Southwestern Medical Center . But there ’s a possibility that the contractions can triggerpreterm labor , Aftab said . Dehydration that continues into working class is also hazardous , because it can run to complications such as low blood press and low blood volume , she said .

For all of these reasons , it ’s important that pregnant women stay hydrous . " We sleep together that not a lot of good thing will take place if a mother is dehydrated " in gestation , Aftab said .
Some inquiry has even linked warm weather condition in sure part to an increase jeopardy of preterm birth , stillbirth andlow - nascency - weightbabies in a population . For example , in a study published last month in theAmerican Journal of Epidemiology , researchers looked at whether exposure to sure temperatures in pregnancy was tied to the risk of low birthing weight ( less than 2,500 g , or 5.5 lbs . ) , using a population of more than 2 million babies born in California from 1999 to 2013 . They encounter that every 10 - arcdegree increase in temperature above 60 degrees Fahrenheit ( 15.5 grade Celsius ) was linked with a 16 - per centum increase in the risk of low-down giving birth weight .
The cogitation found only an association , not a definite cause - and - upshot family relationship , and did not take into chronicle whether a mother had way of reducing her picture to warm temperatures , such as through airwave conditioning . As such , more studies are needed to confirm the findings .
However , the report " adds to the grow soundbox of lit that suggests that pregnant women and their foetus are vulnerable universe following ambient estrus pic , " the researcher wrote . " During heat advisory warning , pregnant woman should be included as a vulnerable subgroup for extra caution , " the discipline concluded .
Aftab said that , on raging days , meaning womanhood should essay not to bide in the Sunday too long and should debar exposure to lineal sun by staying in the ghost . To stay hydrated , the Cleveland Clinicrecommendsthat significant woman drink in 10 to 12 spectacles of fluids per day .
