  This is Scientific American’s 60-Second Science. I’m Cynthia Graber. This will just take a minute.

If you’re like me, you get a jolt 1 of energy from socializing, and hanging out with large groups of friends, because we’re extroverts 2. But if we’re too social, those activities might make us more susceptible 3 to sleep deprivation 4. Seriously – that’s the finding of a study in the journal SLEEP.

Scientists from the Walter Reed Army Institute of Research recruited 48 adults, age 18 to 39. They were tested to see if they were introverts 6 or extroverts. They all got a good night’s sleep. Half then spent twelve hours in group activities, from 10 am ‘til 10 pm. The other half conducted similar activities, but did so alone.

Then both groups were subjected to 22 straight hours of sleep deprivation. They were tested hourly for either wakefulness or motor skills. During the period of forced sleep deprivation, extroverts who’d been keyed up by being social had slower reactions than extroverts who’d been alone.

The researchers say this understanding is important for shift workers and people on military assignments. And here’s a practical application for us extroverts. If you’re at a party ‘til 4 am, even if you’re sober, maybe it’s best to have an alert introvert 5 drive you home.

Thanks for the minute. For Scientific American’s 60-Second Science, I’m Cynthia Graber.
