Sleep apnea is a health condition responsible for short periods of pauses in breathing while you are fast asleep. Individuals struggling with this condition don’t get the right amount of oxygen, which results in interrupted and poor sleep quality.
In several cases, people are not aware they are no longer breathing for some short intervals, and think they still have a healthy sleep cycle. Sometimes, this condition often bears a resemblance to snoring.
Sleep apnea has been linked to an odd number of severe health concerns aside from waking up feeling tired. 
1Keep a Healthy Weight
According to most doctors’ opinions, people struggling with sleep apnea should try to lose some weight. Obesity, especially around the upper part of the body, contributes to your chances of having your nasal passages narrow and airway obstructed.
The obstructions result in sudden stops in breathing even for a longer time during your sleep. Keeping a healthy weight helps promote clearer airways and minimize your chances of experiencing any of the sleep apnea symptoms. Studies have shown that modest weight loss in obese people can help avoid the need to go for a long-term CPAP therapy or upper airway surgery.
