Frequent long drives can cause fatigue – do you know the scientific driving posture?

After the Spring Festival, the weather gradually warms up, and road trips become a popular choice for many people; long drives are thus inevitable. But many people feel tired and uncomfortable while driving for long distances due to an incorrect sitting posture. So what is the correct sitting posture? What considerations should be kept in mind when driving long distances? Many drivers are not aware of the correct driving posture. An uncomfortable seating position in the vehicle can lead to improper adjustment of the pedals and an unsuitable back tilt, causing the driver to lie almost like on a bed, with their feet stretched out toward the pedals while their hands and shoulders move forward toward the steering wheel, forming a \"banana\" shape. This posture forces the spine to bend in an unnatural way, which can easily lead to deformation of the back muscles and intervertebral discs, compressing the nerves and causing lower back and back pain. So, what should be the sitting position while driving? There are four criteria for the correct driving posture: 1. The distance between the top of the head and the roof of the car should be one fist’s width, to prevent the head from hitting the roof during bumps ； 2. The ears and the center of the headrest should be on the same horizontal line, to ensure that the headrest can support the head in the event of a rear-end collision ； 3. With the shoulders firmly against the seat back, extend the arms naturally so that the wrists can rest precisely on the edge of the steering wheel ； 4. When any pedal is pressed all the way down, the knees can still bend without being fully extended. Furthermore, the driver can adjust their sitting position from time to time, adjusting the seat so that it is comfortable to sit on; in particular, the back of the seat should support the lower back, thereby providing support for the muscles there. When driving for long distances, drivers should also pay attention to the following three points: 1. Do not drive continuously for more than two hours; take a break of 10–20 minutes every 1–2 hours. When resting in a service area, it is advisable to get out of the vehicle and move the waist and legs, as this helps to relax the muscles in the waist and promotes blood circulation throughout the body, thereby effectively reducing the incidence of back pain. 2. Avoid frequent hard braking. When braking suddenly while driving, inertia and forward momentum cause the driver’s body to lurch forward; at the same time, the neck and lumbar spine also bend sharply forward before snapping back to their normal position. Over time, this can lead to \"swinging injuries\". 3. Pay attention to adjusting the temperature inside the vehicle. Many people are used to closing the windows and turning on the air conditioner as soon as they get in the car. The cold air from the car’s air conditioner, when directed at the human body from close range, causes the blood vessels and muscles in areas such as the face, arms, thighs, and calves to contract, resulting in reduced blood flow and a slower pace of blood circulation in those areas.
