I live in Yantai now, and the temperature is already quite low at night. Now let's look at how to "hydrate" furniture in autumn and winter. Like human skin, wooden furniture loses moisture and shrinks when the air is extremely dry, and the surface of hardwood may develop minor cracks.
        Even when the sun isn't strong, the air in northern China is very dry in autumn and winter (except for coastal areas like mine, where it's quite humid). Dry air is very bad for solid wood furniture; whether the wood cracks is largely related to humidity. Therefore, in autumn and winter, it's best to minimize the time windows are open and appropriately increase indoor humidity. This is not only beneficial for people's living environment but also greatly helps in the maintenance of wooden furniture.

We've discussed color fading issues extensively, but humidity also significantly impacts paint quality. Indoor furniture should be kept away from doorways, windows, and drafty areas, and especially avoid direct sunlight, as these can cause cracking and color fading. These are two extremes. Additionally, it's crucial to protect indoor fabric furniture from moisture and fire. Don't underestimate this; fire prevention is extremely important. I once set my bed on fire using a hairdryer.

When cleaning furniture, it's best to use a slightly damp cloth, but not too wet. This will moisturize the furniture without causing it to become damp. It's also best to keep furniture away from radiators and heat sources, maintaining a distance of at least one meter. Using a humidifier can also help improve the dryness of the indoor air.

In addition, many plants can also humidify the air, and they are more natural, environmentally friendly, and low-carbon.
