In order to better understand the state of constant overload that many people are exposed to nowadays, a little biology is necessary, as this feeling is related to the unconscious dwelling in the sympathetic nervous system.
The sympathetic nervous system is a part of the autonomic nervous system that is responsible for increasing performance and is activated in stress and emergency situations. When we were attacked by a dangerous animal in the Stone Age, the sympathetic nervous system was activated immediately: our heart rate increased, our breathing became faster, our muscles became tense and our blood supply increased. This was so that we could flee or fight quickly. It was therefore a helpful preparation of our ingenious body for what was to come.

When the danger was over, the body calmed down again and switched to relaxation, to the parasympathetic nervous system. By the way, animals also react in the same way: if a gazelle is attacked by a panther, it runs or fights and when it survived, it shakes itself properly and continues to graze peacefully.
This wave movement of ups and downs is very important for a healthy, regulated nervous system.

Constantly dwelling on arousal, the sympathetic nervous system, has long-term negative consequences on many levels.

Nowadays, however, many people find themselves chronically overstressed and can no longer find peace and quiet from the excitement.They are even unconsciously constantly looking for reasons to stay in an excited state, they really need the constant excitement.

The first three years of life are the most important for learning to regulate the nervous system.Babies and toddlers cannot regulate themselves, but are dependent on the regulatory ability of their caregivers. If, for example, they are not comforted as quickly and as well as they need to be, or if they are not allowed to express their feelings without being judged, or worse if they experience violence, they remain more and more in a state of agitation.

This is why many adults today are chronically overwhelmed, regardless of what is happening on the outside. The key to regulation is not the outside, as this cannot be influenced or can only be influenced to a limited extent.

The key is internal, namely training your own ability to regulate, and fortunately this is also possible in adult life.
