Sugar and junk food rewards the brain, releases dopamine to make us feel happy. Eat it while we are working on a difficult task makes the task feel less stressful by building a reward loop.
To take advantage of dopamine release,
- Eat healthy most of the time to establish a baseline, when sugar high hits, it actually triggers the reward loop.
- Learn to distinguish difficult task. Some task are naturally more difficult, requires structuring of information, long process, or multiple hard decisions; sometimes mediocre tasks seem difficult because we feel tired.
