Caralean : Thus you see the affiliation? Weight gain will be an indication of poor sleep habits. And conversely, being over weight can create serious sleep disorders. Sleep apnea occurs when an individual's higher airway narrows or obstructs while they sleep. In delicate cases it results in snoring, however it will also cause high blood pressure, diabetes, and low blood oxygen levels. As you gain weight your neck size will increase. This enhances the danger to suffer from sleep apnea. Therefore here again the burden/sleep association can dramatically impact your health.
