Welcome back to another episode of Arnold's Pump Club.

Today is a special episode where I'll try a different format.

Instead of the usual episode where I discussed the latest research on multiple topics,

I want to dig a little deeper on just one study.

Not sure if we'll do more of this.

But when Adam shared this study, I thought it was fascinating

and that we had to dig into some of the details.

We know that sleep is essential for recovery, energy, and performance.

But your sleep might also reveal more about your brain health than you think.

A new study suggests that the time it takes into REM sleep, known as sleep latency,

maybe an early warning sign of cognitive decline and Alzheimer's disease.

Researchers analyzed data from participants who underwent sleep monitoring and biomarker testing

for Alzheimer's. They looked at cerebrospinal fluid and neuroimaging markers associated with amyloid,

beta, and toa, two key proteins linked to Alzheimer's.

The researchers divided the participants into early and delayed REM sleepers.

On average, the early group reached REM sleep approximately 95 minutes after falling asleep,

while the late RAM group reached it more than 190 minutes after falling asleep, while the late RAM group reached it more than

190 minutes after falling asleep. Those with Alzheimer's were more likely to have delayed

REM sleep, and they also tended to have higher levels of the two toxic proteins, 16% more amyloid

and 29% more taunt.

They also had 39% less of a healthy protein called brain-derived neurotrophic factor,

which drops in Alzheimer's.
