Pregnancy According to experts, women should try and keep out of the sun during pregnancy. This warning was issued by the Royal College of Obstetricians and Gynecologists, and comes at a time when the UK is expected to have a sweltering hot summer.

This advice is particularly relevant to those in early pregnancy because babies develop most rapidly in the first three months after conception.

Besides, it is also said that pregnant women are much more sensitive to higher temperatures, which can make them feel sick.

Additionally, a number of studies have suggested that babies can be affected by heat during the first 12 weeks of pregnancy.

The royal college said that women should not panic, but should take steps to protect themselves.

A spokesman for the royal college said yesterday: “Women in their first stages of pregnancy in the summer should be aware of the health risk surrounding increases in temperature.

“Pregnant women should stay out of the sun, wear loose clothing, keep well hydrated and eat healthy food little and often.”

Pregnant women should also stay in the shade between 11am and 3pm when the sun is at its hottest.

To cope with a heatwave, expectant mothers are also advised to eat more light meals, such as salads, and plenty of fruit and vegetables.

They should also avoid strenuous exercise which can raise the body temperature even further. Light to moderate exercise is okay.

Mothers-to-be should also avoid tea, coffee and alcohol, which can all increase the risk of dehydration.
