10 taboos that are not based on science but pregnant mothers "believe in them"

Pregnancy is a time of many emotions for every woman. It is the time when women are most concerned about their health and taboos. Therefore, there are many mistakes or rumors related to this stage.

For example, many people believe that a pregnant woman should eat for two, but this is completely false. You only need 300 calories a day for your baby to grow healthily; eating more can be counterproductive, leading to health problems and weight gain.

According toBright SideBelow are 10 common pregnancy taboos that mothers pass on to each other but are not based on science.

1. Pregnant women should not dye their hair.

Research from the College of Family Physicians of Canada says that women can dye their hair during pregnancy. The amount of chemicals in hair products that our skin absorbs is very limited, and it will not cause any harm to the fetus. However, pregnant mothers still need to note:

- Wait until the second trimester to dye your hair.

- Make sure the hair dyeing room is well ventilated.

- Do not leave the dye on your hair for too long.

- Always wear gloves if you dye your hair yourself.

- Limit hair dyeing to 3-4 times during pregnancy

2. Pregnant women should not fly.

Studies have shown that air travel does not cause any negative effects on pregnant women and their fetuses. The amount of radiation a person receives during a round-trip flight is below the upper limit of safe levels.

The only risk is if your pregnancy is unstable, it is best not to be above 9,000 km above the ground, so check with your doctor if you want to fly.

In addition, you should also avoid flying in the following cases:

- At 36 weeks of pregnancy or more

- Have respiratory problems, heart disease

3. Pregnant women should not take hot baths.

A recent study by the University of Exeter suggests that pregnant women can relax by taking a hot bath. However, there are some things to keep in mind. First, you should not take a bath for more than 20 minutes because this can increase the risk of infection. Second, the water temperature should not exceed 36.6 degrees Celsius to avoid reducing blood flow to the baby - this causes stress for the baby.

4. Pregnant women should not eat instant meat.

The main concern with eating these foods is bacteria and the risk of infection is higher for pregnant women. That's why pregnant women often avoid cold cuts, soft cheeses, unpasteurized milk, etc. However, that doesn't mean you can't eat hot dogs or sandwiches. Just make sure you heat the food to a temperature above 70 degrees Celsius.

5. Pregnant women should not sleep on their backs.

There is no clear scientific evidence that sleeping on your back causes health problems or has a negative effect on your baby. However, some studies recommend avoiding this position in late pregnancy because it may carry some risks. During the first and second trimesters, sleeping on your back is safe unless your doctor has advised otherwise.

6. Pregnant women should not drink alcohol

A study from the University of Bristol has shown that there is little or no harm in drinking one to two glasses of wine a week for pregnant women. However, you should not drink too much, just sip a little when socializing or to control morning sickness.

7. Pregnant women should not drink coffee

Coffee itself is not dangerous for pregnant women, but caffeine - which is also found in tea, cola, chocolate... can have negative effects on the fetus. Studies have not found any evidence that drinking tea or coffee (as long as it does not exceed 300 mg of caffeine per day) causes health problems for mother or baby.

So, in case you "crave" coffee, you can have one cup at a time, but stick to decaf coffee (which has at least 97% of its caffeine removed).

8. Pregnant women should not exercise

This has been a popular belief for a long time, but it is completely untrue unless you have serious pregnancy health problems. Studies have even shown that exercising during pregnancy has positive effects on both mother and baby.

Safe forms of exercise for pregnant women include aerobics, stretching exercises, yoga... Professional athletes can continue their exercise regimen during pregnancy but should reduce the intensity.

9. Pregnant women should not eat sweets.

Eating too much sugar isn't good for anyone, but it's especially bad for pregnant women. The best choice is a balanced diet that limits sugar (especially processed sugar). However, that doesn't mean you have to say "no" to cookies or a few pieces of cake if you really crave them.

10. Pregnant women should not eat seafood

Eating fish during pregnancy is safe. It is rich in vitamins and minerals, as well as omega-3 fatty acids. The main rule is to avoid shark, swordfish, and fish high in mercury. You should also limit certain types of fish such as tuna, salmon, herring, and sardines.
