Why Losing Muscle With Age May Make Bad Sleep Worse for Your Brain
This review suggests keeping muscle and metabolic health strong may support better sleep and brain resilience.
This review connects three things that decline with age: muscle, sleep, and brain health. The author suggests that muscle loss, belly fat, and insulin resistance may make sleep more broken. That fragmented sleep, in turn, may leave the brain more open to Alzheimer's changes. This is a proposed framework, not proven cause and effect.
