How Do I Lower The Humidity In My Home Without Dehumidifer?

You could make sure there is plenty of ventilation especially when you run a bath or shower. Don't hang washing around the house and if you have a tumble dryer make sure that the vent goes as far outside as possible. Keep heating on low as much as possible rather than not have it on and then put it on high. And i think you an also get another product instead of dehumidifier to help which is basically a tray of something like salt and bicarbonate of soda which will draw in the moisture to the tray. Hope this helps.
