Superstitions are a part of Indian culture, but did you know that some of them have scientific explanations? Let's explore 5 such beliefs!

1. Breaking a mirror brings 7 years of bad luck. Scientifically, it's because the sharp glass pieces can cause injuries and infections.

2. Hanging lemon and chillies to ward off evil eye. The acidic smell of lemon and the pungent smell of chillies repel insects and pests.

3. Sweeping the house after sunset brings bad luck. In the past, there were no lights and sweeping in the dark could lead to accidents.

4. Placing a black dot on a baby's forehead to ward off evil. The black dot is actually kajal, which has antibacterial properties and protects the baby's eyes.
