Deep sleep vs REM: Which is more important?

Dear Friend,

The sleep industry is a booming market worth $65 Billion.   I am constantly seeing ads for new mattresses, wearables, and devices.  Podcasters are claiming their sleep supplements are the holy grail.  Sleep is clearly a priority and a problem for many people.

Let’s look at a few examples from our clients:

1. 48 y/o M with 15 minutes of deep sleep per night, but otherwise feels rested and no perceivable sleep issues. No increased genetic risk for dementia.

2. 65 y/o F with a family history of dementia, taking high dose Ambien

First we need a quick overview on sleep

Deep Sleep:

• Occurs early in sleep phase (9pm-3am)

• Important for brain “maintenance”, washing out of built-up proteins through the glymphatic system: Key in dementia prevention

• Duration decreases with age 

REM Sleep:

• Occurs later in sleep phase (3am-midday)

• Refreshes brain for future learning, associated with high functioning and mood 

Back to our examples:

 1.     We tried a time shift to go to sleep earlier and reduced late night carbohydrates with some improvement. Next is to try cold exposure and explore sleep supplements.

2.     Decreased Ambien use, still weaning off but hopeful to discontinue completely. Hormones likely a factor, now supported with HRT and supplements.  Next step is to explore cognitive behavioral therapy for insomnia (CBT-I) with accredited centers around the country.

 Next time we will discuss the problem with sedative sleep medications.

Sleep is one of the main levers to prevent the onset of dementia.  At BodyTimeMD, we look to optimize all aspects of your health. Hope this provides some insight, let’s talk if you are interested in finding out more about your body.
