Fill a medium saucepan with water and place it on the stove over medium heat.
Add the cinnamon sticks to the water, ensuring they are submerged slightly as the water heats.
Bring the water to a gentle simmer, watching for small bubbles to form and steam to start rising.
Stir in the vanilla extract, releasing a sweet, fragrant aroma as it mixes into the simmering water.
Reduce the heat to low, allowing the mixture to continue simmering gently without boiling away too much water.
Observe bubbles rising from the water, and notice the steam filling the room with a warm, inviting scent.
Occasionally, gently stir the mixture to help release the scents fully and keep the cinnamon infusing evenly.
Replenish with hot water if the level gets too low to prevent burning or burning smell; continue simmering for about 15-20 minutes.
Once your home is filled with a cozy vanilla cinnamon aroma, turn off the heat and carefully remove the cinnamon sticks.
Pour the fragrant mixture into a decorative bowl or leave it on the stove to continue emitting scent as long as you wish.
Enjoy your natural, homemade air freshener that creates a warm and inviting atmosphere in your home.
