Jacki, I still have the handout of notes on Energy Conservation from the OT in rehab. They're so sensible & easy to follow in everyday life.
But it totally tips upside down the usual belief that we keep running on the energy we have available & then collapse in a heap of fatigue when it runs out. Rather, it says think of energy as money in the bank .... which you store up and keep.
Like you plan your activities for the day with plenty of rest periods which you take BEFORE feeling tired. They don't have to be long.... just stop & do absolutely nothing, go blank in body and mind. In those times you're actually storing up your energy as if you're putting it for safe keeping in the bank. It even suggests you do things like splitting activities into two parts... with a brief blank rest period in the middle. So doing half the dishwasher, then coming back later to finish is spot on. But, BEFORE, you feel fatigued. Even maybe taking a break between showering & dressing. Each person gauges their own program according to their own fatigue level.
Believe me it works.... & it's an approach which can be applied in anyone's everyday life. ... but not on the detailed & intense scale which would follow major medical treatment. Interestingly, quite a few of my friends, who have no serious medical treatment issues to rehabiltate from .... have grabbed the notes on Energy Conservation to do just that.
To be frank, I'm puzzlied why rehab is considered a normal part of post-medical treatment in heart surgery & conditions, but, with breast cancer women seem to be largely left to deal with issues on the grounds they're inevitable...so just suck it up. I have a theory, it's because there's a higher proportion of men who are treated in the cardiac world.... but it's mainly women in the breast cancer world.
