I slept with naphthalene balls in my room which were left open freely (so i was inhaling the fumes unintentionally at night) . will it affect my health or anyone else?

Exposure to naphthalene fumes can have negative effects on human health, especially if inhaled for prolonged periods. Naphthalene is a white crystalline compound with a strong odor that is commonly used in mothballs and other household products. It is classified as a possible carcinogen and exposure to high levels of naphthalene has been linked to an increased risk of cancer.
