Honestly I think there is. It's like the old satin "if life gives you lemons make lemonade". That's how I feel you can minimise the impact of these negative things - try really hard to see the silver lining. 9 times out of 10 there will be one, no matter how small.
Initially though let's have a think about the least healthy way to deal with these situations. That's got to be, in my opinion, to dwell on the problem. Running the scenario over and over in your head is ok for a period of time but at some point you need to rationalise it, understand it and be able to move on from it. Getting stuck in the period where you can't quite understand it will make it difficult to move on. You may have experienced this yourself or seen it in others close to you and it's not nice. It takes lots of energy and sometimes feels like you just can't win. In this situation your stress levels are going to be high, super high. They're going to be so high that they will manifest physically. You could lose sleep, lose your appetite and feel drained. Generally being like this for long periods of time will take its toll on your health and fitness.
So what can you do about it for yourself or to help others?
I find the acronym SARA works really well for me. Each letter stands for a word that describes a different stage of the process that we go through to help deal with surprises.
S - shock. Obvious meaning to this one. If you weren't expecting it you'll get a shock. This could last a few seconds or even weeks.
A - anger. Generally at this stage you're over the shock but now feel angry at the event. Why did it happen? Who's fault is it? And many other similar questions can manifest at this point.
R - rationalise. This is sometimes the hardest step to take. Once you've got through your anger you will start to calm down and try and understand why it's happened. Once you've got an understanding you can then...
A - accept. This is a very important step as it's where you can start to draw a line underneath the event.
Once you understand these 4 steps you can start to recognise them in yourself or in others that are dealing with surprises.
How does this link to health and fitness though?
Basically all you need to do is understand what stage you or that person are currently in and do what you can to help the move to the next step. Once you've got that moving the stress levels will decrease and life will start to return to normal more quickly.
Bear in mind though, some of the time it is healthy to stay a bit of time in each stage!
