Well, you’re not alone.

Many people feel this way with roughly one-in-four men and one-in-nine women having a disorder known as sleep apnea which contributes to their tiredness.

“Sleep apnea is a disorder where the muscles around a person’s airway over relax and close the airway while they sleep,” says Dr. Shapiro from Toronto Sleep and Alertness Clinics. “With the airway closed, a person essentially stops breathing for a short period of time.”

Here are three indicators that you should speak with your family doctor about sleep apnea on your next visit:

Snoring

While not all snorers have sleep apnea, it’s a pretty good indicator that you are experiencing some sort of blockage in your airway while you sleep – generally, the louder the snore, the more likely you have sleep apnea. This is because snoring, coughing or snorting tends to be your body’s way of re-opening your airway when it closes.

High-Risk Groups to Get Sleep Apnea

Like a lot of medical conditions, sleep apnea tends to be seen in certain groups a little more often. If you fall into one or more of these five groups you have an increased chance of having sleep apnea:

• Overweight – BMI over 25
• Smokers
• Have a family member(s) with sleep apnea
• Over the age of 40

Tired All The Time

If you’re getting six-to-eight hours of sleep a night and still feeling tired all the time, chances are you have some form of sleep apnea. In extreme cases, people will sometimes even find themselves so tired that they will fall asleep while driving or in a conversation with a friend.
