Being hungry!
Your body needs energy to be able to run, play, study, read a book or simply watch TV! How does it get energy? From food. Everything we eat is transformed into nutrients that can be used as fuel by our cells. Let’s follow the food in its journey through the digestive system, which is the system responsible for this transformation, called digestion.

Nothing contributes to our wellness more than a good sleep! During our sleep, though, our body doesn’t simply pause. It does a general check-up of all its vital systems!
When we sleep, are we completely still?
When we are awake, our brain is always alert and receives stimuli all the time. What does it do when we sleep?
What are dreams?
Because sleep is a fundamental phase for our body, we need to dedicate the right time to it: how many hours should we sleep every night?
