Heatwave and early childbirth

Significant and very real risks

Indeed, according to a study conducted by D^r Nathalie Auger, women are 27% more at risk of giving birth early, but not prematurely. Here, the distinction is important: we speak of an early delivery when it occurs between the 37^e and the 38^{e week of pregnancy, whereas prematurity occurs before 37 weeks of gestation.}

Stress for the body

During pregnancy, blood volume and body temperature slightly higher than usual are factors that promote dehydration and cause stress on the body. Consequently, the irrigation of blood in the uterus is reduced, which has the effect of increasing the production of hormonesresponsible for uterine contractions.

Consequences not to be overlooked

Early delivery, even at the end of pregnancy, is not without consequence. It would seem, in fact, that babies born before term are more likely to suffer from respiratory problems. Without excluding the risk of death which is also higher in these conditions.

The key: hydration

To guard against the harmful effects of heat waves during pregnancy and minimize the risks of early delivery, certain precautions should be taken. First of all, the future mother must ensure that she is well hydrated. To do this, she must drink between 8 and 10 glasses of water a day and not wait until she is thirsty to do so.

Signs of dehydration

Knowing how to recognize the signs of dehydration is also essential in order to remedy the situation quickly or to consult a he alth specialist if the general condition of the woman were to deteriorate. Among the symptoms that can put the flea in the ear, we find dizziness when changing position, headaches, dry mouth, dark or abnormal-smelling urine, inelastic skin, tongue swollen, chapped lips, etc.

Help thermoregulation

Since at the end of pregnancy, thermoregulation is more difficult, this combined with the fact that the heat does not help the situation, the pregnant woman must imperatively stay cool. Outside, she must wear a hat, clothesadequate and look for shady spots, just as she must avoid staying too long in the sun or even making physical efforts. Of course, taking a dip in the pool is a must, as is taking cool showers.

Although in late pregnancy stomach aches, bloating and heartburn tend to suppress expectant mothers' appetites and gargantuan meals are not usually on the agenda, we will mention that it is better to avoid them. Since digestion contributes to increase the internal temperature, in periods of great heat, the taking of several small meals is recommended to the detriment of more copious plates.

That said, taking care of yourself and listening to your body and warning signs is probably the best option for reducing the risk of early childbirth.
