“Why I still woke up exhausted despite 8 hours of sleep (and how I fixed it)”

I slept a full eight hours every night but woke up tired every morning. I tried everything, from an expensive mattress to supplements. Yet I never felt rested. My partner said I snored, but I thought that was harmless. Until I discovered what was really going on.

October 2025, by Jeroen Smits, 46 years old.

I remember thinking that snoring was some kind of family trait. My father did it, my uncle too, so I just accepted it. My partner heard it, I didn’t. I usually just turned over and kept sleeping.

But snoring turned out to be more than a funny noise. It was a sign that I was breathing incorrectly.

Mouth breathing causes your tongue to fall back, narrows the airway, and creates that rumbling in your throat. Meanwhile, your body takes in less oxygen. No wonder I woke up feeling rough every morning.

When I started reading about it, the penny dropped: I was simply breathing through my mouth all night. Something I never thought could have such a big impact on how I felt.

The hidden consequences of mouth breathing and snoring

What many people don't know: every time you snore, your airway is actually partially blocked. That means your body literally has to work harder to get enough oxygen.


Result: your sleep becomes lighter, your heart rate increases, and your brain gets less oxygen. This explains why so many people wake up tired despite eight hours of sleep.

In the short term, you notice this with a dry mouth, a scratchy throat, and morning fatigue.


In the long term, research shows that chronic snoring is associated with a higher risk of cardiovascular disease, memory problems, and even sleep apnea.


So snoring is not a sound you can ignore, but a signal that your breathing is going wrong.

Waarom ademen door je neus zóveel beter is dan door je mond

Nasal breathing

Keeps tongue and jaw in natural position

No dry mouth or irritated throat

Supports immune system by filtering air

Supports heart and brain in the long term

Activates the ‘rest-and-recovery’ system (parasympathetic)

Mouth breathing

Jaw drops open, tongue falls back → snoring

Dry mouth, thirst, and scratchy throat

Unfiltered air → higher chance of irritation and inflammation

Increased risk of sleep apnea and heart problems

Put your body into stress mode faster (sympathetic)

When I learned more about breathing, I realized how big the difference is. It literally determines how your body recovers during sleep.

With mouth breathing, dry, cold air flows in unfiltered. This dries out your throat and causes you to absorb less oxygen.

Nose breathing works very differently: the air is filtered, humidified, and calmly sent to your lungs. As a result, you get more oxygen from each breath and sleep more deeply.

Overday I managed, but at night it went wrong

When I knew all this, I tried to consciously pay attention. During the day, I kept my mouth closed more often and focused on breathing through my nose.

That actually went quite well. But at night, it turned out to be a different story. No matter how often I went to bed with good intentions, I still woke up with a dry mouth.

My partner even said I was snoring again, while I thought I was finally doing well. It frustrated me because I really wanted to wake up feeling rested. Apparently, your subconscious quickly reverts at night: mouth open, throat vibrating, sleep disturbed.

I kept searching until I came across something that sounded logical, but at the same time a bit strange. Taping your mouth shut to sleep better? At first, I didn’t believe it, but when I tried it, I immediately noticed the effect.

“But… can’t I suffocate then?”

My first thought was honestly:

'"what if I can't breathe because of this? "

Just the idea gave me a bit of stress.

Once I tried it, I noticed that thought quickly went away. Your body is designed to wake you up if something is really wrong. And if that happens, you can easily remove the tape.

What helped me get used to it was starting with the Classic blue mouth tape from Snoozeless. It is lightly breathable and immediately gave me a safe and familiar feeling.

Getting used to it, but I felt the difference immediately

It felt a bit strange the first few minutes, but then I just fell asleep. When I woke up, I immediately knew something had changed: I felt fit, clear-headed, and rested. My partner laughed and said it had been quiet in the bedroom.

It almost sounds too simple, but that's exactly the beauty of it

Mouth tape lightly seals your mouth so that your nose naturally does the work. It is the only way to train yourself to breathe through your nose even at night. And you notice it immediately in your sleep.

What I personally appreciate the most is that I feel much more stable during the day. Not that I suddenly became an athlete, but just fitter and sharper. I can handle my work better and even have energy left in the evening to do something fun.

Which mouth tape suits you?

I stuck with the Classic, just the standard breathable version from Snoozeless. Nice and practical.


My wife? She was sold immediately when she tried the Mouth Tape Deluxe. “This is actually a night cream and a snoring solution in one,” she joked. Because it contains collagen and vitamins, her skin feels softer.

She’s happy, I’m happy, and most of all… finally quiet nights.

What I also wanted to know myself (maybe you recognize it)

“Is mouth tape really good for your skin?”

I wondered that right away too, because I quickly get irritated skin. But honestly, it was much better than I expected. The tape feels soft and doesn’t damage your skin like regular bandages. And if my lips felt a bit dry, I just used the Deluxe version. It works almost like a night cream for your lips.

“What if my nose is blocked?”

That happens to me sometimes too. Then I just stick on a nose strip that opens my nostrils and makes breathing easier. And if that doesn't quite help, I just skip a night. It's not a disaster if you don't use it once in a while.

“Isn't it super uncomfortable?”

The first night feels a bit strange, I admit that. But I noticed you get used to it quickly. For me, it felt completely normal after just a few nights.

The best mouth tape I have used so far. And with the 60 Nights trial sleep guarantee, you can be sure you have nothing to lose.
