Sleep is closely associated with heart health. Two recent studies offer further evidence for the sleep-heart-health connection. The first study that monitored 10 patients with Restless Leg syndrome (RLS) found that Blood pressure rose during Periodic leg Movements and that the rise in blood pressure was greater in older patients and those who suffered from RLS for a longer period of time. The second study which focused on 164 people with Heart failure and Obstructive Sleep Apnea (OSA), found that untreated OSA increased the risk of death in patients with heart failure as compared to those without OSA.
