The advice of grandmothers has been shaped over multiple generations, so many wonder why modern science does not pay more attention to it. We have looked at some of the most popular grandmother's tips and checked what science says about them.

1. Homemade chicken soup as a remedy for a cold

When we catch a cold, we often turn to a cup of hot chicken soup. This warm dish not only warms the body but also helps alleviate cold symptoms. Research shows that warm liquids, like chicken soup, help in releasing and expelling mucus from the respiratory passages, easing breathing and reducing nasal congestion. Moreover, chicken soup contains the amino acid cysteine, which is similar in properties to acetylcysteine found in medications for treating bronchitis and other respiratory issues. Cysteine helps in thinning mucus, making it easier to expectorate.

2. Honey as a natural remedy for cough

Honey has been valued for its medicinal properties for centuries, especially in relieving cough. A study involving 105 children aged 2 to 18 years showed that honey is more effective in reducing cough compared to some common medications. Children who consumed honey before bedtime coughed less and slept better than those who received standard medications or no treatment. Researchers believe that the viscosity of honey and its natural antioxidants help soothe irritated throat and expedite healing.

3. A teaspoon of sugar to stop hiccups

Hiccups can be annoying, but grandmother's advice says that a teaspoon of sugar helps stop them. This method is based on the theory that sugar stimulates the vagus nerve, which connects the brain to the stomach, thereby interrupting the hiccup reflex. Although scientific research in this area is not extensive, many people report the effectiveness of this method.

4. Bread crust is the most nutritious part

Children often leave the crust on their plate, but grandmothers claim that the crust is the healthiest part. During bread baking, Maillard reaction occurs, forming antioxidants. These antioxidants help fight harmful free radicals in the body, which can reduce the risk of certain diseases. So, next time you want to remove the crust, think again.

5. Avoiding cold to prevent a cold

Grandmothers often warn against exposure to cold to avoid catching a cold. Although colds are caused by viruses, research shows that exposure to cold can weaken the immune system and increase susceptibility to infections. A study from Cardiff University showed that individuals exposed to cold were more likely to catch a cold compared to those who stayed warm. Cold causes constriction of blood vessels, reducing blood flow and the supply of white blood cells, crucial for fighting infections.

In conclusion

Grandmother's tips often have solid foundations in real life and science. Although they may seem simple, many of them are based on observations and experiences, which are now also supported by scientific research. Of course, it is important to seek professional help for serious health issues, but for minor ailments, we can rely on the wisdom of our grandmothers.
