Do you wake up tired even after a full night’s sleep? Sometimes what is happening at night is that you’re not getting enough oxygen while you’re sleeping because the airway to your lungs is closing off either partially or fully resulting in poor sleep. Sleep apnea can be a real threat to overall quality of life. Mandibular repositioning appliances help to place the lower jaw forward, opening the airway and allowing people to breathe better, which results in a better night’s sleep and a feeling of rejuvenation. These appliances, like a snore guard, are indicated primarily in mild forms of sleep apnea. More severe forms may indicate other treatment options to ensure you’re sleeping well. If you think you might have sleep apnea, the best thing to do is see your doctor and do a sleep study, where you’ll spend the night in a facility that allows someone to truly measure and quantify how well you’re sleeping. Based on the results, you could then be on the path to more restful sleeps in the future, helping you enjoy the things you love to do without fatigue.
