Final answer:
Before driving while drowsy, ensure you have a good night's sleep and plan your route to reduce stress. Rest adequately to avoid impaired brain and nervous system functions while driving.
Step-by-step explanation:
Before driving while drowsy, it is crucial to take action to ensure safety. Getting a good night's sleep is one of the most effective methods to avoid drowsiness behind the wheel. It is recommended to get to bed early the night before planning to drive to be well-rested.
If you find it hard to sleep, keep your bedroom at a cool temperature between 60 and 67 degrees, avoid stimulants like caffeine and nicotine, and try not to consume heavy meals or alcohol before bedtime.
Another important aspect is rest; without adequate sleep, not only does your brain and nervous system begin to function more slowly, but your reflexes also slow down, and your cognitive abilities diminish, increasing the risk while driving.
Planning out your driving route in advance can help reduce stress and the need for cognitive effort that might be taxing if you are already tired. It is essential to avoid starting a journey while drowsy to prevent potential hazards.
