Investigating the Causes of Drowsiness Triggered by Car Rides.

Drowsiness Induced by Vehicle Vibrations

The phenomenon of feeling drowsy during the operation of a vehicle, such as a subway or bus, is associated with the vibrations produced by the vehicle. The subtle up-and-down movements generated as the vehicle moves forward impact the body. These vibrations follow a predictable pattern, and the brain tends to categorize them as "unessential information," leading to relaxation to minimize energy consumption. This process often results in the onset of drowsiness.

 

Drowsiness during car rides or other modes of transportation can be influenced by lifestyle patterns or environmental changes.

 

Impact of Elevated Carbon Dioxide Levels in Enclosed Vehicles

Modes of transportation like subways and buses involve relatively enclosed spaces. Consequently, the concentration of carbon dioxide inside the vehicle can rise. Increased carbon dioxide levels lead to a reduction in the amount of oxygen inhaled with each breath, depriving the brain of sufficient oxygen supply. Insufficient oxygen supply can induce a lethargic feeling and drowsiness. The presence of many people in a confined space, such as inside a vehicle, can further elevate carbon dioxide levels, making it easier for drowsiness to set in.

 

Drowsiness Caused by Motion Sickness

Motion sickness during driving can induce drowsiness. Motion sickness arises from conflicting sensory inputs in the visual, vestibular, and proprioceptive systems, causing disturbances in the brain. These disruptions can result in symptoms such as headaches, nausea, and abdominal discomfort. The brain, in response to motion sickness, attempts to relax the body and ignore sensory information, making it easier for drowsiness to take over.

 

Dealing with Drowsiness

Move your body while sitting: In a vehicle, making slight movements, such as tapping your feet or gently rocking your body, can improve blood circulation and reduce drowsiness.

 

Maintain air circulation: Adequate air circulation inside the vehicle is crucial. Open windows to let in fresh air or use the vehicle's ventilation system to supply fresh air.

 

Take breaks when drowsy: If you feel drowsy, avoid driving or engaging in critical tasks. Instead, take a short break in a safe location. A few minutes of rest can help alleviate drowsiness.

 

Drowsiness during car rides or other modes of transportation can be influenced by lifestyle patterns or environmental changes. To ensure safe driving or participation in events, sufficient rest and safety precautions are essential. If drowsiness persists, seeking advice from professionals may be necessary.
