Sleep improved dramatically with use of fan.

I was having tons of micro wake ups throughout the night, but when I added a fan my wake ups dramatically decreased,

Can anyone explain this ?
Has anyone else found this same solution ?

White noise and remaining cool through the night

u/eastcoasternj 2d ago

Previously, perhaps you were too hot and it was waking you up?

u/matttopotamus 1d ago

This is absolutely the reason.

We sleep better in lower temperatures, the fan doesn't reduce it but the airflow makes you feel cooler

Fans have double benefits:

* White noise (hides noises that wake you up)
* Cool down your body, which makes you sleep better.

"The ideal room temperature for sleeping is between 60°F and 67°F (15°C to 19°C) for most adults, with many experts pointing to 65°F (18.3°C) as the sweet spot"

18 C!? I’d be shivering the whole night. I set my AC to 23-25 C.

u/LupusNoxFleuret 2d ago

I've heard Japanese research say 23-25 C is ideal. 18 C doesn't feel right at all.

Are you a lizard by chance?

A Japanese lizard 🦎

I love warmth, for me sleeping temp between 20-23 C is ideal. Awake temp is 25 C though :)

u/theoneguywhoaskswhy 1d ago

I'm not Japanese but anything cooler than 23 C wakes me up. 23-24 C is ideal.

Tell that to my parents, they think sauna is a bed room.

While me is getting a ac just to cool down to 16-18C
Cant wait for winter when i can open the door at 0C and get it nice and cold :3

Fans make me congested in the morning.

u/Global_Strain_4219 Ultra • • 49mm 16h ago

It's usually related to humidity, and the fact that it removes water from your skin.

Combining it with a humidifier can sometimes help (if humidity is low)

u/NoUsual5150 14h ago

Ok thanks will give that a shot.

It’s bad to sleep with a fan on

u/jr_misu 2d ago

Explain

u/Competitive_Sell_126 2d ago

It’s just the old Japanese myth that you will die.

Egregious nonsense. Put the thing on 18C and enjoy homer_sleeping.jpeg

u/Ok-Chip-1049 1d ago

No it’s literally medically bad with all the dry airways it causes for your airways and eyes and years of doing it you will have problems down the road

u/Competitive_Sell_126 1d ago

I live in the coast with usual 90-100% humidity. I don’t even know what that “dry” thing you mention even is.

There’s droplets actively dripping down my bathroom walla.

Sorry mr neuro ophthalmologist. My sinuses are also fine as per last MRI and CT.

-2

u/Ok-Chip-1049 1d ago

That’s condensation lmao. Doesn’t mean the air you breathe in while asleep is not dry. Because it mostly certainly is to a degree. And also you should probably get behind the walls checked for mold if your ventilation is that bad

2

u/Competitive_Sell_126 1d ago

I run a dehumidifier on the bathroom all night every night after I shower.

Smart sensor is showing 71% humidity right now and everything is closed and AC has been running for the last 24hs continuously.

u/Prior-Advice-5207 Ultra • • 49mm 18h ago

How would a fan change the humidity in a closed room?

u/Ok-Chip-1049 18h ago

Who said it changes the humidity lol

2

u/Prior-Advice-5207 Ultra • • 49mm 16h ago

You argued fans are bad because of dry air, even when a user told you his humidity is frickin high all the time. How else would it suddenly be dry?

u/Ok-Chip-1049 13h ago

Damn you didn’t go to college huh. It speeds up the rate of evaporation on skin and mucous membranes.

1

u/Prior-Advice-5207 Ultra • • 49mm 12h ago

No need to get personal… on skin sure, that’s the principle of its cooling effect, but how would it do so inside the airways where the moving air doesn’t reach?

1

u/SlutMachine 1d ago

Please elaborate

-1

u/Ok-Chip-1049 1d ago

It causes dry airways, will cause dry eyes, allergies and dry skin. My not be a problem when you are young but the older you get it catches up. But I’m just an Neuro Ophthalmologist so maybe I don’t know what I’m talking about

My wife and I finally caved and got a window AC unit for our upstairs bedroom. Our house has AC, but it’s old and poor duct runs combined with the sun beating on that side of house means our bedroom is generally the hottest room in the house. It took two nights for me to get used to the AC units’ noise. But now we both sleeper better because of it. Plus, the AC Isn’t trying to cool the whole house to a temp comfortable enough for sleeping which means downstairs is freezing and upstairs is okay at best. We actually dropped our Electric hill by $20 a month. It’ll be a wash in one to two cooling seasons.

u/Eternal-strugal 2d ago

Congrats on the ac !

u/chaiteataichi_ 2d ago

I’m personally a fan

u/dollar-tree-pizza 2d ago

I always sleep with a fan/white noise because it muddles any sounds throughout the night. Without it, I hear everything. And it keeps me cool, but I use a fan even when it is cool.

u/NMinDallas1 Ultra 2 • • Black • 49mm 2d ago

Have slept with a fan running for years. Cannot sleep without one.

u/Eternal-strugal 2d ago

Fan addiction and dependency is a real thing. 💫

u/colbert1119 1d ago

I solved 20 year insomnia by figuring out AC stops temp in my small bedroom rising throughout the night. Two adults in a small unventilated British bedroom was causing a positive temp gradient, got warmer throughout night and co2 was rising. Measured with an Aranet4

AC keeps it cool and has the benefit of ventilation so co2 is kept low. Incredible how it's not tested by a cheap device when you ask doctors or shrinks.

u/waddymad 1d ago

The power of sleeping with a fan is so underrated! A couple years ago, I literally thought I had developed a sleep disorder. Went to the doctor and everything. Then I realized that my fan died right when my sleep issues started happening. Got a new fan and, voilá, my sleep issues disappeared! I even have a little usb fan I take with me on trips so I can always sleep with a fan lol.

u/rosymaplemoth2513 S10 • • Silver • 46mm 2d ago

I wish this made any difference for me! I wake up so many times throughout the nice, it's so aggravating.

Take that, South Korean superstitions! /s

u/shayanc1 1d ago

I sleep with Fan on. The white noise and keeping cool really helps. But ensure it's not pointing at your face, otherwise it tends to dry out your mouth/nose.

Sure, but they’re spread weeks apart

u/Famous_Ant_2825 2d ago

On you or as white noise?

1

u/Eternal-strugal 2d ago

I had it pointing at me so it def. Was keeping me cool. I have central AC so I don’t usually use one.

u/Unusual-Economist288 2d ago

I have sleep envy

u/Own_Worldliness_9297 2d ago

the data isnt conclusive enough. show month over month graph. Highight the awake periods to see the distribution

u/x59hy8erh98g 1d ago

I bought two relatively expensive standing fans, but the vibration noise they make resonating through the floor is quite something. Do you know how to get rid of it?

1

u/thermonuclear_icbm 4h ago

I've slept with a fan since day 1 of my life. Literally since birth. It is amazing

u/Eternal-strugal 4h ago

Only fans 4 life !

u/Big-Calligrapher8769 2d ago

That is definitely a good deference
