It’s no secret that having a pigeon chest affects your breathing. Does it disrupt the air pathway enough to cause snoring? Since this condition makes the head just out and shoulders slump over, the top of the body is leaned forward. This can affect the neck enough to cause interruption of breath during sleep to make you snore. Luckily stretching can help to improve these issues. Neck and shoulder stretches can treat the problem area. Hip flexor and chest stretches can also help the issue by treating the imbalances throughout the body.
