    Sleep apnea is a common sleep disorder than can affect as many as five percent as adults, but often goes unrecognized. If you suffer from this condition, you will stop breathing for up to a minute while you sleep. This can cause snoring, fatigue, and other problems. Fortunately, there are effective treatments to help you find relief.

    Try using a mouth guard that’s custom-fitted for you. These are made especially for those suffering from sleep apnea. If you don’t have CPAP, then this guard is an excellent alternative. Also, it’s a lot more comfortable wearing this mouth guard while sleeping. It really helps keep the airways clear and keeps the soft tissues of the throat stable.

    If you have sleep apnea, yet you drink alcohol and smoke cigarettes, quitting could alleviate your symptoms. Both smoking and drinking promote relaxation of the airways causing sleep apnea and excessive snoring. If you avoid these things, it may help your sleep apnea.

    Improve your sleep apnea by slimming down a bit. Recent research showed dramatic improvements in overweight men who shed 25 pounds over a period of one year to reduce sleep apnea symptoms. In some cases, the weight loss resulted in a cure of sleep apnea where no further treatment of the condition was necessary.

    Try your best to lay off tobacco and nicotine products. Cigarette smoke can irritate your upper airway causing it to swell up, subsequently hindering your ability to breath during the night. Quitting smoking could therefore, significantly improve your sleep apnea symptoms and will also improve your body’s overall health and your feelings of well-being.

    Check if a corrective device can help alleviate your sleep apnea symptoms. Having an overbite, an undersized jaw or a recessed chin can cause your airway to be more narrow because of how your jawbone is set. These devices help create proper alignment of your jaw while you sleep, opening up your airway more. As a result, you experience fewer sleep apnea symptoms.

    Avoid any type of drugs or alcohol if you are experiencing any type of sleep apnea. Drugs and alcohol will slow down your respiratory system, and that is known to be one of the causes of sleep apnea. If you are struggling with this issue, try to get some professional help to overcome these addictions.

    Drink one cup of caffeinated coffee a few hours before you go to sleep. It may seem silly to drink a caffeine drink at night, but this can actually help keep your throat open while you sleep. You may have to play around with what time you drink the coffee to avoid restlessness.

    If you are a trucker who has sleep apnea, take precautions to stay safe on the road. First of all, get yourself properly diagnosed and treated. If your doctor prescribes a CPAP, use it. They are small and easily portable and can run on battery power if necessary. Try to stay fit and get regular sleep to keep your condition under control.

    As the above article has demonstrated, you have many different treatment methods available to you when it comes to sleep apnea. Everyone is different, and it’s important to find out which treatment option will fit your specific situation best. If you use these tips, you will get better sleep at night. Sleep apnea doesn’t have to run your life; you can take control back today.
