What happens when you smell your favourite meal?

When you smell your favourite meal, the molecules of the food's aroma enter your nose and bind to receptors in the olfactory bulb. These receptors then send signals to the brain, which interprets them as smells.

The brain also releases dopamine, a neurotransmitter that is associated with pleasure and reward. This is why people often feel happy and relaxed when they smell their favourite foods.

Smelling your favourite meal can also trigger memories of past experiences, such as family dinners or meals that you enjoyed on vacation. This is because the brain associates certain smells with memories and emotions.

In addition, the smell of food can also affect your appetite. If you smell a food that you like, you may feel more hungry and be more likely to eat it.
