How might managing one's own physical health affect the stability of social systems beyond the individual's life?

Physical health seems likely to lead to two effects.

1. More cognitive resources available for decision-making. When you get healthier, you first gain some room to breathe. Of course, if exercise has overactivated the sympathetic nervous system, one could say cognitive resources are reduced in that state, but if health improves overall, that should be positive for managing chronic stress and create more spare resources. The more personal resources increase, the higher the probability of rational decision-making, and the stability of society as a whole will also increase.
2. Restoration of self-efficacy. There was an earlier post that raised concern about 'successfully carrying out tasks that are achievable,' but I think the positive effect is greater for people whose self-efficacy is weak and who experience strong anxiety and depression. This is because the anxiety felt right now must be relieved before there is room for a rational approach to Embrace. Therefore, through these two main pathways, managing health will raise the stability of society itself.
