Wind Prevention for the Back of Office Chairs

For wind prevention at the back of office chairs, traditional methods can be referred to, and currently, there are no modern specialized designs or products available.

Traditional Wind Prevention Methods

Cao Tingdong, a renowned health expert in the Qing Dynasty, proposed in his book Lao Lao Heng Yan that if a chair does not lean against a wall at the back, wind can easily blow from behind, creating what is known as "evil wind," which may have adverse effects on human health. To block this evil wind, a method of placing three folding screens ("mountain-shaped screens") around the back of the chair can be adopted.

• Screen Style: The "mountain-shaped screen" is higher in the middle and lower on both sides, resembling the shape of a mountain. This design not only has a certain aesthetic appeal but also better conforms to the contour of the human back, providing more comprehensive wind protection.
• Screen Size: The total width of the screen should not exceed one zhang (approximately 3.3 meters). This size is neither too bulky to occupy excessive space nor too small to effectively block the wind coming from behind the chair.
• Expanded Functions of the Screen: In addition to its basic wind-blocking function, the screen can also be used to write mottos or calligraphy, adding a cultural touch and serving as an inspiration or decoration.

Modern Situation Explanation

Currently, search results do not mention any specialized designs or products for wind prevention at the back of modern office chairs. This may be because modern office environments are generally more enclosed, and the use of air conditioning and heating systems keeps indoor temperatures relatively stable, reducing the occurrence of "evil wind." However, in some special cases, such as in open-plan offices or positions near windows or doors, there may still be issues with wind blowing on the back.

Recommendations

• Utilize Existing Items: In the absence of specialized wind prevention products, existing items such as clothing or blankets can be used to temporarily shield the back and reduce the invasion of evil wind.
• Adjust Office Position: If possible, try to adjust the office chair to a position against a wall or away from air vents to fundamentally solve the problem of wind blowing on the back.
• Pay Attention to Health: Prolonged exposure to an environment where the back is subject to wind may have adverse effects on health. Therefore, it is important to pay attention to one's health condition and take timely measures to prevent the invasion of evil wind.
