When exposed to high humidity, wood absorbs moisture from the air, causing it to swell. Conversely, in low humidity conditions, the wood releases moisture, leading to shrinkage. These changes in dimensions can put stress on the wood fibers, resulting in cracks.

2. Effects of High Humidity

In regions with high humidity, wood can absorb excess moisture, leading to swelling. This swelling can cause the wood to become distorted or cupped, as well as increase the likelihood of cracks developing. The excess moisture absorbed by the wood can weaken its structure, making it more susceptible to damage.

When the humidity remains consistently high, the wood may not have a chance to dry out, which can promote the growth of mold and fungi. This can further compromise the integrity of the wood and accelerate the crackling process.

3. Effects of Low Humidity

In contrast, low humidity can cause wood to lose moisture, resulting in shrinkage. As the wood dries out, it becomes more brittle and prone to cracking. This is especially true for hardwoods, which tend to have less moisture content compared to softwoods.

During the winter months or in dry climates, when the humidity levels drop significantly, wood can experience rapid moisture loss. This can lead to the formation of cracks, splitting, and even structural damage in severe cases.

4. Preventing Wood Crackle

While it’s nearly impossible to completely eliminate the effects of humidity on wood, there are steps you can take to minimize wood crackle:
