After living in San Antonio for a few years, you can see how the winter weather here has fluctuating humidity levels.

Just yesterday, it felt like the humidity was below 10 percent, so even sitting at home made my nose tingle and my lips dry. Laundry would become crisp within an hour of hanging, and waking up at night would leave my throat scratchy, making me reach for water.

However, just one day later, the humidity can suddenly jump to 60 percent, with low clouds covering the sky, making the entire city feel damp. When you step outside in the morning, your glasses fog up, and when you open the car door, the inside glass is blurry. It makes you wonder if you're in the same city.

Even funnier is that after a strong north wind blows all night, the weather changes completely. When you open the door in the morning, the air feels crisp. The humidity feels like it's below 15 percent again, and touching the doorknob feels prickly, while static electricity pops when you're arranging the blankets, and your hair seems to create its own art piece. On days like this, you might wonder if you should turn on the humidifier, but after two days, it becomes damp again.

So, a humidifier in San Antonio is quite a tricky thing. In places like New York or Chicago, where it's dry all winter, it's a must-have, but here, it's too unpredictable.

It can be dry for a few days, then humid, and suddenly dry again, feeling like the air changes with the wind direction rather than the season. One day, lip balm is essential, and the next day, it's sticky enough to make you look for a fan.

Still, personally, I think having a small humidifier is a good idea. It's especially helpful for those with sensitive noses or who often wake up with a dry throat at night. However, it doesn't need to run 24 hours; just turning it on briefly when the humidity drops below 20 percent is sufficient.

Buying a hygrometer to keep on your desk and checking the numbers is the most practical approach. If it's above 40 percent, you don't need a humidifier. If it's higher, you should turn it off.

San Antonio is neither a desert nor a coast, so the weather always confuses people.

If you ask whether a humidifier is essential, it's not a daily necessity but more like an emergency tool that you use when needed.

Living in this area is more about adapting than relying on equipment. If it's dry today, drink plenty of water, and if it's humid tomorrow, turn on the air conditioning, and when the wind changes, pull out warm clothes again to wear.
