Complaining and the Brain
It is intuitive that a negative attitude and constant complaining are bad for us – but can it really affect our brain? It turns out that there is a growing body of evidence suggesting that negativity can alter our perception of life by changing the connection of the neurons in our brain. This would then result in increased stress levels, which is linked to chronic diseases and mental health problems.
A common perception of complaining, or “venting”, is that people feel better after getting their emotions out. Contrary to popular belief, however, studies have shown that expressing negativity can be bad for the mood of both the complainer and the listener, and here we briefly discuss a few findings on how negativity can impact our well-being.
Do negative thoughts affect the wiring of synapses in our brains?
The synapses in our brain are separated by spaces known as synaptic clefts. When we think, synapses “fire” and send signals across these clefts to other synapses. This forms a bridge by which signals and information and transferred. The exciting thing here is that upon each trigger of an electrical charge, the synapses involved are actually brought closer in proximity to each other. This increases the likelihood that the correct synapses will share the appropriate link and fire together. Consequently, it becomes easier for that particular thought to be triggered.
What all this means is that thinking about something initially makes it easier to think about it again in the future. As such, if a person is constantly unhappy, it makes it more likely that he or she will continue to have negative thoughts if nothing is done about it. On the bright side, though, this also suggests that if we make a conscious effort to think positive thoughts, the positive feedback cycle helps us to become a more optimistic personality as well.
By repeating pessimistic thought processes, synapses that represent these negative inclinations gradually grow closer. Given that the thought that is most likely to surface is the one which can form a bridge between synapses in the shortest period of time, it is unsurprising then that in this case a pessimist would be more likely to remain the way he or she was.
