Most of you have probably heard about the study conducted by the European Hydration Institute back in 2015 that concluded that dehydration has the same effects on a person as driving under the influence of alcohol. Whether its tiredness, headaches, dizziness, and slower reactions times, these symptoms have been suggested as being evident in cases of people who are dehydrated or are under the influence. Nissan is well aware of the situation and is addressing it with Dutch design brand Droog. Their solution? A sweat-sensing material on the steering wheel and driver’s seat that informs drivers when they’re dehydrated and in need of some rehydration.
