The skin gives us information about temperatures via receptors. As a rule, the heat in the sauna makes our blood pressure go down. The subsequent sensation of cold on the skin does not just stimulate the peripheral blood circulation. A reflex reaction via the autonomic nervous system causes our blood pressure to rise to the normal level again as well.

Information and ideas:
Use picture to introduce topic with the question "What can we feel with our skin?", e.g. cold, heat, wind etc.
