The dangers of driving after restricted sleep and moderate alcohol intake

In a recent study, combining moderate alcohol consumption (within legal limits for driving) and moderate sleep restriction led to greater drowsiness and increased deficits in attention, compared with either sleep restriction or alcohol intake alone.

The synergistic effects lasted between 2 and 3 hours. Also, peak impairment occurred not at peak alcohol levels but 30 to 60 minutes after, despite receiving rest intervals in between testing.

Wearable sensor helps people keep tabs on drinking

Electrical engineers are creating a wearable sensor to help people manage their alcohol intake.

Activity trackers monitor your steps; this innovative sensor measures your blood alcohol level. Worn like a watch, this sensor picks up vapors from the skin and sends the data to a server. If the alcohol reading is high, via an app, a designated loved one gets an alert to check in on the user. This easy-to-wear gadget will help address issues with social drinking and addiction.

“We wanted to create an unobtrusive sensor that would be easy to wear, and help people struggling with alcohol,” said the inventor, Shekhar Bhansali, an Alcatel Lucent professor and chair of the Department of Electrical and Computer Engineering. “This is one step toward active intervention that only requires the user wear the sensor.”
