# Snore and Dry Mouth > Open-mouth breathing at night dries tissue. What it can mean and what to ask. A plain-English guide with practical steps. ## Guides - [Common Reasons People Snore](https://snoring-and-dry-mouth.pages.dev/snoring-causes-basics/): Snoring happens when air makes soft tissue in the nose and throat vibrate during sleep, and several everyday factors can narrow that space. - [Why Your Mouth Dries Out Overnight](https://snoring-and-dry-mouth.pages.dev/dry-mouth-at-night-causes/): Mouth dryness overnight usually comes down to less saliva, more air passing over your tongue and cheeks, or both. - [Whether Sleeping on Your Side Helps](https://snoring-and-dry-mouth.pages.dev/side-sleeping-snoring/): For many people, sleeping on the side reduces snoring because gravity pulls the tongue and soft palate back less than it does when lying flat. - [Nasal Congestion and Sleep Breathing](https://snoring-and-dry-mouth.pages.dev/nasal-congestion-sleep/): When your nose is blocked, you tend to breathe through your mouth in your sleep, which often brings louder snoring and a dry mouth by morning. - [When to Ask About a Sleep Study](https://snoring-and-dry-mouth.pages.dev/sleep-study-referral/): Ask about a sleep study when snoring comes with witnessed breathing pauses, choking awake or heavy daytime tiredness, rather than waiting for it to resolve on. ## About - [About Snore and Dry Mouth](https://snoring-and-dry-mouth.pages.dev/about/): not medical advice, how the site is funded and how guides are made ## Optional - [RSS feed](https://snoring-and-dry-mouth.pages.dev/feed.xml)
