I have always assumed (I know, I know, assumptions are dangerous) that there would be a positive correlation between healthiness and general effectiveness.
The truth is that I very much want to believe this to justify the time and energy I invest in staying healthy. I start every day with a brisk 50 minute walk (the dog takes me); I do Pilates exercises for core strength and balance; I swim often; I eat plenty of vegetables and fruit; I stay within the recommended number of alcohol units; I don’t smoke; I check that my BMI does not exceed 25; and, naturally, I believe everything, yes everything, I read in the newspapers about the advantages of a healthy lifestyle.
But is it worth it? Am I kidding myself? Does being healthy mean that I am more effective at work?
I have just lapped up an article by Longenecker and Yonker that says lots of the things I want to hear (that’s why I lapped it up). They claim to have conducted research that shows that a healthier manager is a more effective manager and produces better results. Here are just some of the benefits claimed by their sample of high-performance managers:
- increased energy and drive;
- greater physical stamina and endurance;
- lower levels of stress;
- increased cognitive and thinking abilities;
- improved overall productivity and performance;
- easier to maintain a positive attitude; and
- improved confidence and self-esteem.
The list goes on, with me feeling an increasingly warm glow of self-satisfaction. Please don’t spoil it by asking tedious questions such as what the sample size was, or whether they had a comparator group of unhealthy managers, or what their definition of healthy was, or whether they found high-performing managers who weren’t healthy. You see, I don’t want to know any of these things. They might destroy my cosy consonance and create dissonance – and that wouldn’t be healthy.
