Obstructive Sleep Apnoea is when the airway at the back of the mouth repeatedly partly or completely obstructs during sleep. The breathing is reduced or may stop altogether. The oxygen level then falls and you wake up briefly to start breathing again. These episodes may happen many times across a night. Some people know that their breathing is not normal all night, but may be unaware that they have a problem.
Restless Leg Syndrome is an irresistible urge to move the legs while at rest. A person with RLS will experience a vague, uncomfortable feeling only relieved by moving the legs. The symptoms of RLS may be present all day long, making it difficult for an individual to sit motionless. Or they may be present only in the late evening. Late evening symptoms can lead to sleep onset insomnia, which tends to compound the effects of RLS.
