Is it Healthy to Drink a Glass of Water That’s Been Sitting Overnight?

Many of us have this habit of leaving a glass of water on your night table, so we can guzzle it when we wake up thirsty. But is this water safe to drink? 

Please read on to settle the debate if you should or shouldn’t drink it.

1. An Open Glass of Water is Susceptible to Contamination

Leaving drinking water in an uncovered glass isn’t sanitary. Some debris or dust may settle on it overnight, and you may not notice the surface scum when you drink it. 

However, a water pitcher or bottle can cause problems even if closed. For instance, your nasal discharge, dead skin cells, sweat, or dust can backwash into the water when you drink from it. 

As a result, your mouth may inadvertently contaminate the remaining water. Moreover, your saliva also has bacteria that may incubate in the water and cause harm when you drink it.

Therefore, remember to consume the water from the water bottle in one go if you drink straight from it. Otherwise, it would help if you immediately discarded it.

2. Can You Get Sick from Drinking Water That’s Been Sitting for Hours?

The truth is, it’s improbable that you’ll get ill from your bacteria. You can drink water from used mugs, drinking glasses, and water bottles without getting sick. 

However, it would be best if you didn’t share them with others, especially the immunocompromised patients. People with HIV/AIDS, undergoing chemotherapy, or transplant patients can’t consume contaminated water.

You may have known that tap water is slightly less healthy than bottled water. However, it’s a myth because both meet hygiene standards.

Moreover, do you know that 25% of the former comes from the primary water supply? Therefore, it’s the cleanest bottled water you can drink.

3. You Can’t Leave Water in Your Car for a Long Time

If you’re fond of bringing drinking water wherever you go, ensure you don’t leave it in your vehicle for too long. Sunlight heats the water, thus making it susceptible to bacteria growth. 

This scenario is especially true if you’ve drunk from it earlier. It would help to keep the water bottle under your seat to limit the heat. However, bacteria can still flourish from it.

Moreover, be careful about plastic bottles containing chemicals such as BPA because they can seep through the water under sunlight. BPA may be harmful to the brain. However, the FDA limits its presence in plastics. 

On the other hand, using BPA-free bottles solve the issue, but bacteria growth is still possible, especially in a metal bottle. The liquid inside can quickly heat up, thus causing the germs to flourish.

4. How to Ensure Safe Drinking Water

You should avoid dehydration; therefore, you should ensure to drink a glass of water from time to time. To maintain good health, refrain from sipping from a water bottle.

It would be best if you didn’t allow your mouth to touch it to avoid contamination. You can pour water into drinking glasses instead. 

Moreover, check the water bottle’s expiration date. Don’t drink it if it’s expired. While water may not pass, if you keep it for long, you’ll only invite bacteria to grow on the bottle.

Final Thoughts

You should be cautious when drinking a glass of water, especially if you leave it sitting for a long time. 

Ensure to prioritize safety by not drinking straight from a water bottle to prevent the growth of bacteria, and strengthen your immune system by not allowing germs and bacteria to proliferate.
