I always feel thirsty indoors in winter and my eyes are dry. What is the reason?

In winter, I always feel thirsty indoors, my eyes are dry, and I drink a lot of water every day, but my throat is still dry, and the chances of my lips bursting to go to the toilet are increasing. I drank a lot of water, but I also felt thirsty. If I find that despite some external factors such as diet and weather, I am still thirsty after drinking a lot of water, do I need to sound an alarm on our foreheads? It is likely that the humidity caused by some diseases is too low: evaporation is accelerated, and dry air can easily take away water from the human body, causing chapped skin, irritation to the oral cavity and nasal mucosa, and symptoms such as thirst, dry cough, hoarseness and sore throat appear. Therefore, the invasion of dry cold air in autumn and winter is easy to induce pharyngitis, bronchitis, pneumonia and other diseases.
