Aims	Content	Material	Time
First session
Acquire knowledge of how sleep works	Explanation of the concepts of chronobiology, biological rhythms in humans, internal clock and synchroniser, and the importance of structures such as the hypothalamic suprachiasmatic nucleus (SCN) or the pineal gland, and the melatonin synthesised by it in these biological rhythms.	Digital anatomical table explaining the different anatomical structures of the body involved in sleep.	30 min
Acquire knowledge of the anatomical structures involved in sleep	Localisation of the structures mentioned in diagrams and anatomical models of the nervous system.	Analysis of the anatomical structure of the brain.	10 min
Acquire knowledge about sleep patterns	Addressing the concept of chronotype and the existence of three times that affect human circadian rhythms (biological, artificial and social), and how a mismatch between them leads to a state called chronodisruption.	Digital screen presentation with summary of main. concepts	20 min
Self-awareness of sleep pattern; analysis of one’s own sleep behaviour	Completion of two self-knowledge questionnaires on sleep patterns: Morning/early morning test and three-times test.
