I've tried a couple. In the end what worked best was some zinc oxide adhesive tape (the type you'd find in a first aid kit). Mind you, the point is not to forcefully tape your mouth shut abduction style. All you need is a small 2cm*1cm strip accross the center of your mouth. Breathing through your nose is the body default.

That said switching to nose breathing is not as easy for everyone. Chronic mouthbreathers often have clogged sinuses and a sensitivity to allergens. Making sure the air quality in your bedroom is good helps and there is a ton of other things you can do.

Ah thanks! I do have sleeping problems - in that I wake up extremely tired even after a good 7-8 hrs of sleep and a very dry mouth. Will try this out.

You should consider getting a sleep test. As far back as I can remember, I have always been tired and sleepy through the years. I just attributed it to being on less sleep due to my erratic schedule. But I was diagnosed with Sleep Apnea at 29, after likely having it for a couple of decades or so.

Been using CPAP for almost 5 years now. Everyday is fantastically fresh with a regular ~7 hours of sleep. Can't recommend it enough. I am also on path to see if my Blood Pressure medicine can be stopped - since it is understood to be the side effect of Sleep Apnea in my case. Should become clear in a few months.

Also, been active for a year. Started just walking in the evening mandatorily - sometimes listening to podcasts, and other times just using it as a break from everything digital. Then, after a few months, split the walk-time into a morning and evening routine. Probably been regular at it for about 395 of the last 400 days. It's a habit now. Added running to the routine but it is a bit erratic still. Want to add HIIT / Weight-training to workout routine, but that hasn't stuck at all and will try again in a while.

As to the results, I am almost 11Kgs lighter from my max weight, feel healthy, BP is almost always normal, BMI is close to normal, resting heart rate has dipped significantly, and so much more. I track a ton of this info as it can help you stay motivated on the slow, low and tiresome days. :)

Wish you all the best - experiment and find something that suits you best!
