Curious phenomenon: these external influences make us hungry!

Would you have guessed it? Our feeling of hunger can be manipulated by external influences. Why and how do such curious things as the waiter's figure, music by Hugo Strasser or swimming suddenly make us want to eat? You can read the exciting answers here.

Mmmh, that's delicious! And followed by dessert. Restaurant guests should not be seduced by the waiter's curves or soft jazz music.

The waiter tempts us to feast

When we go to a restaurant, we mainly pay attention to the food. We pay little attention to the waiter's figure. And that's a big mistake. Especially if we are watching our figure. Because fat waiters tempt us to consume more. This was discovered by researchers from Jena. The reason: we then have no guilty conscience and even enjoy the high-calorie dessert that we would otherwise have denied ourselves.

We also become more indulgent with alcohol

We need to be particularly careful when pleasant jazz sounds are playing in the background, such as Hugo Strasser or Max Greger. This can also stimulate the appetite. This is because it makes us feel good. And that puts us in a gourmand mood. US scientists have come to this astonishing conclusion. Classical music, on the other hand, is said to have no influence on our desire to eat. The experts suspect that we have become accustomed to the sounds because we hear them everywhere, for example in advertising and films. So they don't affect our appetite.

Anyone enjoying a night out with friends should also be careful. If the waitress has extra pounds on her hips, we also tend to drink more alcohol.

Hormones get mixed up in the water

Have you ever wondered why you always feel so hungry after swimming? It's not just the increased energy consumption that's to blame. When we jump into cold water, our hormone balance is briefly disrupted. The body then produces more ghrelin and we feel hungry. At the same time, there is less leptin in the body. This is a satiating hormone. If we swim in warm water, on the other hand, our hormones remain reasonably balanced and we don't get the hunger pangs.

If you prefer the latter, you should go to the swimming pool on a warm swimming day, which is offered once a week in many cities. The temperature is then around 30 degrees.

Watch out, blue light!

US experts are on the trail of another previously underestimated fattening agent: blue light. This is emitted by PC monitors, for example. If we take it in just before or during dinner, our appetite even increases - and lasts for up to two hours! A study reveals this. Apparently, light activates the appetite center in the brain. We can protect ourselves by simply switching off our electrical devices.
