It seems that running from task to task only makes us feel more productive.
Not long ago, the New York Times featured a fascinating article
by Tony Swartz titled “Relax! You’ll Be More
Productive”. I often feel like I have
more to do than my time and energy allow, so I was drawn to the idea. There is mounting evidence in studies done at
prestigious institutions that our habit of working at all hours, skipping lunch
and not using vacation days is making us less, not more productive. Here are
some main points from the article.
1.
To accomplish work we use time and energy. While
both assets are finite, only energy is renewable. If we’re careful to
consistently renew our energy, we’re able to accomplish more in the same amount
of time. A study done in the 1950’s established that we sleep in cycles of
roughly 90 minutes, shifting between light and deep sleep cycles. A decade
later, one of the authors, Professor Nathaniel Kleitman found that our waking
lives work the same way. We move from alertness progressively into
physiological fatigue every 90 minutes.

Professor K. Anders Ericsson and colleagues at
the University of Florida followed performers in the fields of music,
athletics, acting and chess. In all these fields the best performers practice
in sessions of no more than 90 minutes. The most efficient and effective
performers start in the morning, rest between work sessions and rarely work for
more than 4 of these 90 minute intervals each day. Dr. Ericcson notes, “To
maximize gains from long-term practice individuals must avoid exhaustion and
must limit practice to an amount from which they can completely recover on a
daily or weekly basis.
3.
One of
the most damaging results of our penchant for working as many hours of the day
as we can is a lack of sufficient sleep.
A recent study found that sleeping too little, defined as less than six
hours per night was one of the best predictors of job burnout. A Harvard study
estimated the cost to US companies of lost productivity because of insufficient
sleep could be as much as $63.2 billion a year.
This sounds counter intuitive but it’s worth exploring. Using more hours for work doesn’t mean we’re
accomplishing more. Our bodies are not meant to go full steam until we fall
exhausted into bed. The quality and
quantity of our production will increase if we allow ourselves time, even in
the middle of a work day, to renew our physical, mental and emotional selves. But
how do we use this information while fitting into our office/corporate
environment? What do you think? How do you manage your time and energy stores?
