KLAFS ABC of well-being
Following a cold stimulus, your body interacts with your nervous system and releases neurotransmitters such as norepinephrine, adrenalin and the stress hormone cortisol. These neurotransmitters make your blood pressure rise and your heart beat faster, and stimulate your entire metabolism. A heat stimulus triggers the release of endorphins. These not only have an analgesic effect, but also make us feel happy.
