Office Chair and Its Risks
The association between 'office chairs' and 'hemorrhoids (referred to as 'chrysanthemum residue' in a colloquial sense)' primarily manifests in two aspects: the risk of hemorrhoids due to prolonged sitting and the explosion risk of inferior pneumatic chairs.
Risk of Hemorrhoids Due to Prolonged Sitting: People who sit for long periods are prone to varicose veins in the anal cushion due to maintaining a seated posture for extended times, increasing the risk of hemorrhoids. For example, when slumped in a chair rushing to finish a PowerPoint presentation, gravity continuously presses down on the lower body, obstructing local blood circulation in the anus and causing congestion and dilation of the venous plexus. When combined with factors such as a diet high in oil and sugar from takeout (which can easily cause constipation) and prolonged toilet time (such as extended time spent on the phone while defecating), the burden on the anal cushion may further increase, triggering hemorrhoid flare-ups. Typical symptoms of hemorrhoids include rectal bleeding, pain, and prolapse. In severe cases, friction or infection may lead to skin damage around the anus, resulting in the hidden troubles of 'chrysanthemum residue.' Therefore, it is recommended that people who sit for long periods get up and move every 1-2 hours to avoid prolonged pressure on the anal area. Additionally, maintaining a light diet and regular bowel movements can help reduce the risk of hemorrhoids.
Explosion Risk of Inferior Pneumatic Chairs: Some adjustable and rotating pneumatic office chairs pose safety hazards. Pneumatic chairs produced by non-compliant manufacturers may have issues such as insufficient purity of the inert gas (e.g., mixed with oxygen) and poor-quality materials for the pneumatic rod (e.g., using inferior steel pipes). Under high-temperature conditions (such as direct sunlight) or high-pressure environments (such as frequent adjustments), the internal pressure of the pneumatic rod may suddenly increase, leading to bursting. During an explosion, fragments of the pneumatic rod may be ejected at high speed, directly impacting the lower body and causing severe consequences of 'chrysanthemum residue and scattered debris.' Furthermore, the impact force from the explosion may also cause injuries to other parts of the body. To avoid such risks, when purchasing pneumatic chairs, choose products that have passed national safety certifications. Check whether the pneumatic rod has explosion-proof design features (such as steel stamp markings) and avoid using them in high-temperature environments or during frequent adjustments.
In conclusion, the association between office chairs and 'chrysanthemum residue' requires prevention from both health and safety perspectives: people who sit for long periods should pay attention to physical activity and diet, while users of pneumatic chairs should carefully select products and use them in a standardized manner.
