Stress
can increase reward pursuits: This has traditionally been seen as an
attempt to relieve negative affect through the hedonic properties of a
reward. However, reward pursuit is not always proportional to the
pleasure experienced, because reward processing involves distinct
components, including the motivation to obtain a reward (i.e., wanting)
and the hedonic pleasure during the reward consumption (i.e., liking).
[...] Results showed that compared with participants in the stress-free
condition, those in the stress condition mobilized more effort in
instrumental action when the reward-associated cue was displayed, even
though they did not report the reward as being more pleasurable.
What it means:
when you're stressed out, there's more of a desire to "get" something
that you like (i.e. shopping, food, drugs, TV shows, etc.), even if by
the time you get it, it doesn't seem any more pleasurable than usual.
Rather than admonishing yourself for this natural response, or fighting
against its mechanism, it may be helpful getting your brain to associate certain "healthy"
(or preferred) things as rewards (perhaps through repeated pairing of these things with successful completion of a task) in case you feel the need to indulge. It'd require much
less energy in the long run to use a system already in place to your
advantage.
