Dr. Peter McCullough, a cardiologist who is (now was) board-certified in internal medicine and cardiovascular disease, who presented at the conference, said that when people—especially young people—die in their sleep the underlying cause is often myocarditis. Myocarditis, which is inflammation of the heart, can lead to irregular heart rhythms that can be lethal without immediate treatment.

What is causing sudden death of young people in their sleep? They have undiagnosed heart damage such as myocarditis post covid vaccine. Myocarditis is not always symptomatic.
Though it may seem counterintuitive, Dr. McCullough said that sudden deaths that happen during sleep are biochemically similar to the sudden deaths during or just after vigorous exercise. The reason people die seemingly inexplicably in their sleep, Dr. McCullough explained, is sometimes because of a surge in catecholamines during the end of the sleep cycle. This natural biochemical change is the body’s signal to wake up.
Catecholamines are hormones that are made by the adrenal glands. They are released into the body in response to physical exertion or emotional stress. But they are also released during sleep, just before waking, as a signal to the body and the brain that it is time to get up. These catecholamines can increase our heart rate, blood pressure, and breathing rate, among other things.
In the body there are three catecholamines: dopamine, epinephrine, and norepinephrine. A surge in catecholamines, whether it happens during sleep or during exercise, can stress the heart and cause it to beat arrhythmically, Dr. McCullough said.
