How long should yoghurt ferment?

What happens when you ferment yogurt?
To turn milk into yogurt, these bacteria ferment the milk, turning the lactose sugars in the milk into lactic acid. The lactic acid is what causes the milk, as it ferments, to thicken and taste tart. Because the bacteria have partially broken down the milk already, it is thought to make yogurt easier for us to digest.
Can I ferment yogurt 24 hours?
The longer the fermentation the more the bacteria have time to eat – the more they eat, the less lactose there is! The important thing to get is, even after a a standard 8 hour fermentation, the milk still has plenty of lactose. 24 hours is an ideal fermentation time which produces a yogurt with minimal sugar.
Can homemade yogurt make you sick?

How do you speed up fermentation in yogurt?
Turn off the heat, remove the pot of yogurt from the heat, and allow to cool. You want it to cool to between 100°F and 115°F—the perfect temperature for yogurt bacteria to thrive. You can do this naturally, or you can speed up the process by submerging the bottom of the pot in an ice bath.
