There is nothing worse than walking up and feeling congested. Dr. Michael Daignault is well aware of that which is why he presents some of the most common causes of congestion as well as the best ways to stop them from happening.
If your congestion is not caused by an infection or allergic reaction, then most likely it is because of vasomotor rhinitis. If that is the case you may need to provide your head with some extra support while you sleep by adding one or two pillows under it. If you notice that one of your nostrils tends to be more clogged, then the best idea is to start sleeping on the side of the opposite nostril.
Another common cause is the dryness of the winter months. Turning up the heat at night will often lead to the air getting drier. This is an easily solved problem as a cheap humidifier could help add moisture to the air and might allow you to feel better.
If you find that you have a problem with congestion, then one of the best things you can do is to try a nasal rinse or neti pot. This can help reduce any inflammation in your nasal passages, and could even potentially thin out your mucus. A steamy shower will often have a similar effect on your nose.
You should also try to avoid using decongestant medications, as you might find that it leaves you with more side effects than you had hoped for the next morning. Instead switch to a saline spray.
