A large part of stress is caused by social factors. You feel rushed, because you know, that a job should be completed by a certain point in time, or because an acquaintance, who was asked for a favor, has less time, than you take.
Stress isn't always just psychological, but also a social phenomenon, which one can counteract by strengthening one's social skills.
Don't just change the way, how they deal with stress, but they also influence future situations, that could cause them stress! With strong social skills, they will feel less stress, so to speak, and have more energy at their disposal - this method is the "secret weapon" of many seemingly sovereign people, who cope with their everyday life with flying colours.
A first step to strengthen your social skills (especially in personal terms) is to examine the circumstances, that cause them stress. tasks, requirements and situations, which seem to grow over their heads, do not necessarily have to be in their area of responsibility. Maybe they simply let themselves be charged with too many jobs because they are too bad at saying “no”..
Check your everyday life and the last few weeks and months carefully. When did you get angry about it?, that someone has given them a task, which actually wasn't hers at all, and which they then did with care?
Surely you can think of one or two examples, about which they actually think, that they should have declined the task.
In that case, strive for it, to increase their assertiveness and make them clear, that you can't burden them with every task, which just seems practical. Assertiveness not only ensures greater sovereignty, but also for satisfaction. It's a fact, that mostly people, which can be placed far down in the social order, are under a lot of stress.
It is best to start your change in this respect in less explosive situations and keep reminding yourself, was sie erreichen wollen. If they succeed, they will gradually find a better and more considerate way of dealing with themselves and their environment.
So they the social factors, that cause them stress, but can fight effectively, they have to deal with conflicts differently. Unfortunately, many people today suffer from a pronounced aversion to conflict, mostly caused by certain behaviors in their parental home, who don't have a "culture of argument" to take with them.
However, that is no reason, that this deficiency, which is often also felt, has to accompany a person throughout life – one can learn to deal with conflicts, and when you do this, At the same time, you usually make an important contribution to a positive change in your own stress balance.
The first and most important step in this relationship is determination, resolve conflicts in the future. Be sure to, that they openly address problems and that they insist on doing so, that a solution will be found. Often just the people, that cause them stress, are not very cooperative in this regard, because it seems easier for them, unloading your own stress on them through their behavior in one way or another - don't allow it anymore, even if the conflict is difficult for them!
Sometimes it's enough, that they are ready, to take countermeasures, to prevent further inappropriate behavior towards them - humans are socially very sensitive beings, which are guided by unspoken feelings more than one might think. In any case, hold on to your conviction – if you become “soft” again, the old patterns return quickly, and they suffer again from foreign-induced stress.
