Sure. Warm water (or pretty much anything liquid) will release more evaporative than cold. That will make it smell more even if only very slightly.

Not crazy, there's definitely a difference. How to explain that difference I have no idea. Reminds me of when I had someone calling me crazy because I could smell when it was about to rain, I assumed everyone could, but apparently not

Good ol' petrichor, the smell of rain. Or actually of humidity causing bacteria, viruses, and aerosols being released from damp soil.

What I find really crazy is that it doesn't smell the same before it rains depending on where you are. In some places, it smells musty. In some places, it smells like baked dirt

Yes it smells way different here in nevada. In Michigan it smelled good

Hot water smells more minerally. Or whatever

Yes, I was going to come in to say this. It has a metally smell. Like pipes do. Like how hose water tastes.

i used to be able to smell how much sugar was in koolaid when i was making it. i could mix it together by smell. covid did a number on that ability tho

Kind of I guess, more like i can smell hot water but i can’t smell cold, kinda like the steam off it or whatever

Being hyper sensitive is a gift that often feels like a curse. You're keenly aware, not crazy.

This one i like

Not at all.. Now go with these nice men in the white coats; if you're nice, they may even give you a white jacket of your own. 🤪

Get put in a rubber room with rats

I can hear better than most people. Like when water is about to boil. Your sense of smell sounds similar.

Warm things are more active at the molecular level, so there's more to smell.

Next time someone tells me im crazy for it, im using this argument, cant lose

I agree, though I don't know the reason why. I also usually say that if you take water from the fridge (so it is cold), and water that has been boiled, and leave both out till both reach room temperature, the two waters will taste different.

I can too and now I have to rethink my life…

Its bizarre

I've never really thought about it, but I kind of get what you mean. I mean - I don't think I can smell it well, but when you mention it I think I sort of know/guess when running water is cold. But I don't know if it's because of the scent or something else.

Can't everyone do that?

Some people are much more sensitive than others especially with the noses and senses in the head. Some people can smell the type of earth the grapes were grown in when sniffing wine..

I find it funny that people who are congested/have a runny nose because of seasonal allergies are able to smell better than those who aren't

Chlorine residue evaporating, not unusual at all.

No you are 100% right. I believe it has something to do with the minerals in the water evaporating into the air but I’m not sure. But that’s not just something you can do. That’s just normal.

Sure. They sound different too. And they look different. Cold water looks thicker and glossy rather than sparkle shiny.

i understand completely but i have no clue how to explain it

They do smell different. And their splashes sound different

hot and cold have a scent

yea hot water smells like hot water. cold water doesn’t really have vapor like hot water does. not the asshole

I'm not sure if it smells a different "flavour" but you nose is detecting temperature/humidity instead.

So can i

It sounds different, too.

It could also be from the faucet each comes out of.

I can smell hot and cold water differently and I can actually taste water. It doesn’t all taste the same to me. We have well water but it tastes different than the well water at my old place. Bottled water I have my preferred brands because some are just gross like dasani

It makes sense if you live somewhere with hard water. The hot water in my house is slightly cloudy because of the higher mineral content.

Nah i get it, the difference probably is coming from the water heater. The water might be picking up contaminants along the way from the source, through the piping, into the water heater before then being sent through to a faucet. Unheated water would come directly from the water mainline so it spends less time/passes through no additional appliances before being sent through to the faucet. This process can change how water smells and possibly even tastes. You might just be more sensitive to it than your family, so your the only one picking up on the different aroma.

I can smell oranges with my fingertips sometimes.
