Is it bad for your lungs if you shower late at night like around 10pm?

So i have asthma, and i usually shower at night to feel relief and i love the feeling of going to bed and knowing that the dirt and oil is out of my hair. I sometimes get caught up in homework and it take me a while to finish. And i usually finish around 9:50pm and then shower. But my mom says its bad for my lungs and its going to cause a "lung infections" . i asked my dad if i could and he said it wouldnt do any harm to my lungs and if i shower warm and blow dry my hair afterwards. So can i shower like now? (10:36pm)
