Wellness Evidence

A new study from the NIH and Yale indicated that sleep deprivation is linked to higher levels of a protein called beta-amyloid—a well-known precursor to Alzheimer’s disease. Nineteen out of 20 participants had higher beta-amyloid in their brains after a night of exhaustion. And while a small study, it’s important because it’s the first of its kind to test human beings in a controlled setting. It suggests a connection between bad sleep habits and this fatal form of dementia.
