In Russia, whistling inside your home is not just frowned upon—it’s thought to bring bad financial luck. This superstition warns that a person who whistles indoors may “whistle away” their money, leading to financial hardship for themselves or their family. While it may seem like an innocent habit, whistling in a domestic space is often treated with serious disapproval, especially by older generations.
Many households uphold this belief so strongly that guests may be reminded not to whistle when visiting. The idea that wealth can be expelled from a home through sound—particularly whistling—reflects a symbolic link between wind, air movement, and the instability of fortune.
