Drinking a glass of water that has stood bedside overnight

I've pondered over this. I keep a bottle of water in the car and sometimes forget to change it. So if I'm out somewhere and thirsty, is it safe to drink, after, say, 3 days? (after it has been opened).

Oh Sudonim I remember that thread so well! Yuck.

I take two glasses of water up to bed. One for me (which I cover) and one for the cat. She won't drink from her water bowl but does like water from a bedside glass.

I take a glass to bed for the same reason as lots here; dry mouth, early tablets etc. I keep it covered in case of spiders but I’ve never worried about freshness or CO2 and I’m still here. I remember the ‘bathroom water comes from the attic’ era because it used to worry me when I was brushing my teeth but nowadays it’s all from the same piping.

I always take a small glass and a carafe of water to bed, so my sips in the night are freshly poured, even in the dark, you can tell the level of water from the sound it makes.

I have taken water to bed for years because I have sinus trouble and also take meds that give me a dry mouth. So I wake up with a very dry mouth and throat in the nights. Also have to take painkillers sometimes for my back. I have always used a covered beaker to prevent insects or dust getting in the water, and to help avoid spillages. My 35 year old daughter does this too. I drink it during the night but I don' t usually drink it once I get up, after about 7.30. It does seem a bit stale by then.

Keep a small bottle by the bed....

Simple. I use a refillable sports water bottle. Change water daily. Put in dishwasher often.

I always take a small bottle of water to bed, lasts me 3/4 nights,, I only have a little when I get back in to bed from toilet breaks ? and still fresh as lid on tight. ? happy all ok round

Riverwalk I think that the water in the glass reacts with the air to absorb CO2 which makes it taste stale. Water in the pipes would not have contact with the air. This probably explains why water from the tank in the loft tastes different from water directly from the mains.

Thanks everyone for your comments and suggestions. I am pleased that nobody has had any ill-effects from my potentially dangerous habit. ? I think I will carry on drinking my overnight glass but keep an eye open for floating debris, live or dead!

I refill a plastic bottle with water every night and most mornings it is at least half empty. I don't remember drinking it but if |I have no water will wake up with a dry mouth!
I read somewhere that if you drink water before bed you are less likely to have a heart attack in the night, or maybe I dreamt that.
I have drunk water with a fly in it more than once. I have also had water bottles so long that I have discovered a kind of green moss in the bottom, before I disposed of them. As you can see I am still here.

Don't know where the 'ok' came from.

I use a bottle of water or a sippy cup.ok
Stopped using a glass after I knocked one over and the drawer beneath was partially open. That was a mess and a half.

Nobody with a combi boiler has cold water coming from a tank in the attic anymore. With modern systems all cold taps are fed from the mains, so supply drinking water.

I have just read the link to mumsnet...thanks for the laughs. Never gave it a thought back in the day!

Ours used to come from a tank in the attic but it comes straight from the mains now since we were replumbed.

Water in a glass tastes funny next morning. I prefer it in a bottle. I used to use a carafe. I wash the bottle and refill every day.

I would absolutely never drink water from the bathroom tap. It comes from a tank in the attic.

I always take a glass of water to bed and usually drink at least half of it. I take a fresh glass every night. DH takes a glass up and since he doesn’t drink out of it often he will sometimes keep the same one for maybe 3 nights. I have tried to tell him I think that is gross, but he is completely unperturbed! For a while we used water in bottles, but I read that once opened the bottle should not be kept for more than 3 nights and I stuck to that whereas he felt it was fine to keep it until he finished it, could be ages. He seems to have an iron constitution. They do say something about eating a peck of dirt before you die....

Also - penis beaker ??? best thing ever!,

I take a glass of lemonade to bed every night. It must be Schweppes and it has to be sugar free . I’d don’t always drink it but it HAS to be there .

My mum used to have a cup of boiled water with PLJ in it every morning. Remember PLJ ?

I don't know how water that's been sitting at your bedside overnight would be any staler than if it had been sitting in the water pipes in your house, street, town .....

You're very brave bradfordlass are you not scared by spiders either?

I often have a bottle of water to drink the next morning during the hot months. Never been ill from it.

Oh dear, I don’t think I’d like to share my sleeping space with one of those, BradfordLass!

Talking about things dropping into water glasses. Every summer, at least one black field cricket gets into my house and seems to gravitate to the bathroom to find water.

This week, a cricket decided it prefered my bedroom and has been crich-criching all darned night.

I didn't have any hope of seeing it, let alone catching it to put outside, so just had to put up with its noisy companionship. Let's hope it moves on or gives up the ghost.

Last night it tried to share my pillow - perhaps its the reincarnation of my dear husband (he had very black hair) so I'll be kind to it.

I don't like water at the best of times so wouldn't take a glass of it to bed. It's only on the rare occasion that I wake up anyway so it would be a waste of time.

Medics would say I don't drink enough,. but I don't go thirsty either and I wouldn't drink water for the sake of it.
What I do is squeeze a couple of oranges or make lemonade if I happen to be thirsty or have a glass of pure apple juice.

I certainly couldn't drink water if it's been standing all night.
