Many people keep a glass of water next to their bed for convenience during the night or early morning. However, health experts have recently warned that this seemingly harmless habit could pose hidden health risks.
Scientific findings suggest that leaving an uncovered glass of water by the bedside for long periods can expose it to bacteria, dust, and even microscopic insects invisible to the naked eye, increasing the likelihood of contamination. In addition, repeated contact of the mouth with the glass may encourage the growth of germs in the water throughout the night.
Doctors note that water left for extended periods, especially in bedrooms with varying humidity and temperature levels, can create a favorable environment for microbial growth.
To avoid such risks, they recommend using a sealed water bottle instead of an open glass to maintain the purity and safety of drinking water.
Experts further advise replacing the water daily rather than drinking leftover water the following day, emphasizing that this simple precaution helps reduce the risk of infection and supports overall health.
