It started as a warm summer night. Lena, exhausted after a long day, pointed the small oscillating fan toward her bed. The cool breeze felt heavenly, and within minutes, she drifted into a deep sleep.

But when she woke up, something was… off. Her throat burned, her nose was completely blocked, and she couldn’t stop sneezing. Worse, her eyes watered as if she had cried all night.

It turned out the fan had been circulating dust, pollen, and dry air straight into her face for hours, leaving her with an allergy flare-up, sinus congestion, and the kind of stiff neck that made turning her head feel like moving a rusty hinge.

What seemed like harmless comfort had actually given her a night of hidden hazards — and a morning she wouldn’t forget.

Moral of the story: sometimes, that “cool breeze” carries more than just fresh air.
