There are lots of issues that can come from having too low humidity, or air that is too dry.
Thankfully, it is fairly easy to fix the issue.
I almost always have dry air in the wintertime, but for once, I started having issues with the humidity in the summertime. This was unusual because usually the summer is fairly humid. I can tell when the humidity is too low in my house because my lips started to become really dry. Usually when my lips become dry and sore I notice it’s because of the air. In the extreme cases my throat will become sore as well, from breathing in all of that dry air. I make sure to take a lot of cough drops as well as keep my chapstick nearby. But then I take out my humidifier and then fix the issue. Even if you don’t have a humidifier like I do, there are some things you can do to raise the humidity. You can take a bowl of water and place it in front of a fan, or if you don’t have a fan, you can take a spray bottle and spray water in the air to raise humidity. These are things that I did before I got my humidifier. I would highly recommend that anyone who struggles with dry air to get a humidifier, is incredibly easy to set up and take care of, and it will remove all dry air problems. The only issue is that you can’t run your A/C system as much, since air conditioning removes some of the humidity.
