Maybe someone is sneaking into your room while you're sleeping and stuffing dryer lint up your nose ¯_(ツ)_/¯

So, I actually had this because of my humidifier. I was using an ultrasonic humidifier with tap water - I know distilled is recommended, but with how dry it is here, that would mean an insane amount of bottled water. But I noticed a film of white dust appearing around the room from the dispersed salts and whatnot. Turning off the humidifier (and later replacing it with an evaporative style) cleared up my daily stuffiness instantly.

I have nasal congestion due to allergies every morning so here’s some advice that might help you.

You can try a Neti pot morning and night. The NeilMed ones at Costco pharmacies are good.

Use distilled water or boil your own for 1-3 minutes depending on the elevation in the area.

Once the packets run out you can measure 1/8 tsp baking soda, 1/8 to 1/4 tsp non-iodized salt (e.g. sea salt).

For prescriptions, Omnaris might work for you too. Gets things moving and doesn’t have the congestive rebound effect that over-the-counter nasal decongestants do.

All the other advice about controlling allergens is on point too. You can try an anti-histamine (e.g. Aerius) for a week to see if your congestion goes away but allergy meds dry you out a bit by design and gum you up so maybe this won’t have the effect you’re seeking.

You can get a sleep study for apnea but I’d say only if you’ve had actual fatigue related symptoms, not just what you’ve described here.

You could get a breath test for your lungs. Maybe there’s mold at your place. That tightness should be enough reason to get checked out, tbh.

Best of luck!

Tape your mouth when you sleep, when your body thinks it's about to suffocate your nostrils will open right up.

Make sure your tongue is pressed up on roof of mouth right behind your top front teeth when you are awake, keeps you breathing through nose and not mouth.

Go to the gym and hit the treadmill, run as long as you can only breathing through your nose, go back everyday and increase the time by 5-15 seconds.

This combo solved it for me and got rid of snoring.
When I started on treadmill I could only do about a minute of running without mouth breathing, now I can go as long as my legs will last. Don't expect to be able to make it through whole night with your mouth taped, and tape verticle not horizontal, with small easy to remove tape... don't kill yourself.

I've had the same thing for years. You should get checked for sleep apnea... I have it but unfortunately the CPAP machines don't let me sleep. I cannot get used to it.

But I sneeze at least 50 times and blow my nose as much for one or two hours after waking up.

The rest of the day my sinuses are clear. I've asked Doctors and haven't gotten any real solutions.

I've found cleaning my nose before bed has helped - remove the day's snot and boogers rather than sleep with it!

I have mild sleep apnea and a night device that improves my airways has eliminated my sinus congestion in the mornings. Talk to a dentist that specializes in sleep apnea.

My parents do but I do not. I'm guessing we all have sleep apnea though. Definitely allergies. But, I do have a small air purifier in my room

I think it's this one:

My morning shower collects a looot of nasal discharge...

The classic advice is to go see a doctor and with what you’ve described I’d recommend it.

To answer your question, yes I do. However, I have an autoimmune disorder that makes me have a constant runny nose unless I’m on some meds.

Yeah. My nose ends up pretty clogged in the mornings. Blowing my nose before going to bed doesnt do much.

Also I use a hypallergenic pillow case and an air purifier, and that hasnt done much either.

I feel like this is something you should speak to a doctor about, like it could just be a quirk or it could be that fluid is accumulating in your respiratory system when you lay down which could be dangerous.

In addition to other suggestions here (all good ones so far), maybe an allergy? Could be something about your pillow

I’ve been living with this for 20 years and only now seriously seeing an ENT to figure it out. One thing doc has me doing is a twice a day sinus rinse with a NeilMed sinus bottle. It has def improved things a lot.

I say see an ENT and they will probably take a swab to check for an infection. I had one and pill antibiotics didn’t help so he has me doing this rinse with an added antibiotic powder.

Sounds like allergies/asthma. I would go see an allergy clinic and get tested. If you find you have allergies you could consider getting allergy shots.

I have this. For some reason, I find a scented candle helps - I sleep with one lit.

Running the ac while sleeping does this to me.

Well, I want to breathe easily, I guess.
