Why do we choose to help one another? There are many reasons. You may be a

selfless person or lending a hand may be a cultural expectation.
Now, researchers are raising the possibility that good sleep may be a wonderful
ingredient that promotes the alacrity to offer help between human beings. Indeed the
better sleep you have, the more willing you will be to lend a hand. And a surprising
new set of research studies have found that sleep loss may affect our generosity at
different levels.
Researchers at University of California, Berkley, led three small studies to
explore generosity. In one study, they exposed a group of healthy adults to a night of 8
hours of sleep and a night with no sleep. Researchers scanned the participants’ brains
after each night. After a sleepless night, areas of the brain involved in empathy and
helping behavior were less active. In fact, when the study participants were sleepless
at night, 78% of them demonstrated a reduction in the desire to help others.
In the next study, researchers tracked 136 people through online questionnaires
and sleep diaries for a few days. They wanted to see if nightly variations in sleep
affected their desire to help others. They found that, when sleep quality worsened
from one night to the next, there was a major decrease in ‘helping choices’ and vice

versa (反之亦然).

The third study looked at how sleep loss affected generosity on a larger scale.
The researchers analyzed data from over 3 million charitable donations made in the
U.S. They focused on donations during the transition to Daylight Saving Time (DST)
in spring each year During the spring time change we lose an hour of sleep
Interestingly, researchers found a 10% drop in donations in regions that change
their clocks. This drop wasn’t seen in regions that didn’t observe the time change. It
showed that insufficient sleep triggered by the time change impacted donation
behavior.
All these results suggest that insufficient sleep makes us less compassionate and
helpful. Throughout the world more than half of adults don’t get enough sleep during
the workweek, but we should all star valuing adequate sleep rather than treating it like
something optional or unproductive. If so, it will enable us to be more helpful and to
be the best versions of ourselves.
