What are the chemicals in our brain

Chemistry: what triggers feelings in our body

For a long time, researchers have been trying to find out which processes in the organism are responsible for our moods. In doing so, they encountered complex mechanisms that are characterized by the interaction of various chemical messenger substances


This neurotransmitter is released just before a goal is achieved: for motivation. A permanently low level can have a negative effect on drive and ability to concentrate, while too much often leads to hyperactive behavior.


Endorphins are pain-relieving and euphoric substances that are mainly produced in the pituitary gland and the hypothalamus. The body releases them during physical exertion, but also when laughing and singing. They can make you feel very elated.


This neurotransmitter ensures calmness after being released in the brain; it influences the feeling of satiety and the perception of pain. A common scientific hypothesis is that low levels are linked to depression. A lot of serotonin leads to an increased perception of positive (but also negative)
Experiences, in extreme cases it can lead to headaches, confusion, tremors and nausea.


Cortisol increases blood sugar levels and inhibits inflammatory reactions; however, if the values ​​are high, it also slows down wound healing and bone growth.
The body releases larger amounts of this messenger substance, especially in the morning, which are then gradually broken down over the course of the day; in chronic stress, however, this natural daily rhythm is disturbed. In many of those suffering from depression, certain cortisol levels are significantly increased.


In the event of challenges, stress or danger, this substance is increasingly released. Norepinephrine makes you present-minded, focuses attention and has a positive effect on motivation. An excess can lead to restlessness, anxiety and fear.


The so-called "cuddle hormone" sets the course for interpersonal trust in the brain and is released in large quantities during orgasm, but also during childbirth - and initially during breastfeeding. It enters the body via the bloodstream, has an analgesic effect and presumably accelerates wound healing. A high mirror means that cooperation among people close to you improves - but apparently also
to the fact that one encounters strangers with increased distrust.
