La importancia de dormir y soñar

For centuries, it was believed that the most important things in our lives happen while we are awake and that sleep is exclusively a period intended to recover energy so that we can carry on the next day. However, this is not the case: sleep is an essential function for our existence, as important as eating, breathing, or drinking water. In the 24-hour cycle that constitutes a day, an adult sleeps an average of eight hours; this means that we spend 30% of our lives sleeping. The duration of sleep varies from person to person, and just as some “short sleepers” manage to recover their energy with 5 to 6 hours of sleep, “long sleepers” require 8 to 10 hours of sleep to recover completely, and both circumstances are normal. The ideal is to sleep 8 hours a day.
