Why do moving vehicles make me sleepy?

Why Moving Vehicles Make You Sleepy

The rhythmic vibrations of a moving vehicle can have a calming effect on the nervous system, inducing drowsiness. This is because the low-frequency vibrations activate the parasympathetic nervous system, which is responsible for “rest and relax” functions.

When the parasympathetic nervous system is activated, the body’s heart rate and breathing slow down, and blood pressure decreases. These changes in the body’s physiology can lead to feelings of relaxation and drowsiness.

In addition, the rhythmic vibrations of a moving vehicle can also create a monotonous environment, which can further promote drowsiness. The lack of stimulation from the outside world can make it easier for the mind to drift off to sleep.

For some people, the combination of the rhythmic vibrations and the monotonous environment of a moving vehicle can be too much to resist, and they may fall asleep quickly. For others, the effect may be less pronounced, but they may still feel more tired than usual after riding in a moving vehicle for a long period of time.

Tips to Avoid Getting Sleepy While Driving
