Question 7890
To try to avoid drowsiness while driving, it is advisable to sleep...
- fewer hours than needed, to keep your level of alertness high.
- between 5 and 7 hours a day.
- enough hours to be rested, which for most people is between 7 and 9 hours.
Show answer and explanation
Correct answer: enough hours to be rested, which for most people is between 7 and 9 hours.
Sleep needs vary from person to person, but most people need between 7 and 9 hours a day to function well. With 5 or 6 hours, most people don't get enough sleep, and that sleep deficit builds up night after night. Cutting back on sleep to stay more alert does the opposite.
