The Science of Sleep [The Stack 023]

Table of Contents:

Hi Dreamy Stacker,

The science about sleep is constantly shifting and changing, just like a dream. 

In The Stack 014 we discussed Scientific Hints for a Better Sleep including the two types of sleep patterns: “morning larks” and “night owls”. 

The previous study emphasized the importance of shifting towards an “early bird” lifestyle. But this week drifts off into introducing and supporting new patterns of sleep and why it does a body good.

Beyond “Morning Larks” and “Night Owls” 

Psychology Today Magazine, September 2019 edition, featured a study published in Personality and Individual Differences that introduces two new chronotypes (sleep styles). 

  • Researchers asked 1,305 people to complete an online survey. Participants estimated their typical level of sleepiness at different times of the day, their usual bedtime, and quality of sleep.  
  • Alongside the familiar “morning” and “evening” types, the researchers found evidence of “afternoon” types and “nappers”.
    • “Afternoon” people wake up sleepy but are alert in the middle of the day.
    • “Nappers” begin the day alert and remain that way until a bout of afternoon sleepiness, then alertness returns until late evening. 
  • Chronotype and approximate peak alertness: 
    • Early bird: 6am - 9am.
    • Afternoon: 11am - 2pm 
    • Napper: 7am - 10am and 2pm - 5pm
    • Night owl: 9pm - 11 pm 

Body clock influences how well the immune system works 

Medical News Today featured new research published in PNAS, that found that mice immune systems don’t respond equally well at different times of the day, suggesting that the body clock may influence mechanisms related to immunity.

  • Two groups of mice were studied: one with specific circadian rhythm genes that were “switched off” and the other with naturally active genes.
    • They were both given a vaccine to trigger an immune response. 
  • Researchers observed that after the vaccine, the strength of the CD8 T cell response varied according to the time of day.
  • In mice whose CD8 T cells were deficient for the clock gene, the circadian rhythm was abolished, and response to the vaccine was diminished in the daytime.  
  • Scientists found that the CD8 T immune cells that the body uses to fight off infections and cancer tumors, work with various degrees of efficiency at different times of the day. 

Here’s what getting less than 7 hours of sleep a night can do to you 

Healthline presented a Journal of Lipid Research article that addressed how getting less sleep influences triglyceride-rich lipoprotein levels. 

  • The study examined 15 healthy men in their 20s. The men got 5 hours of sleep a night, 4 days a week, followed by one 10-hour night of “recovery sleep”.
    • Researchers assessed the effect of the limited sleep on lipedema (blood lipids) after a high fat meal. 
  • Findings suggest that four nights of five hours of sleep per night, impairs lipids in the blood and that one night of recovery sleep may be adequate for recovery of triglyceride metabolism, but not markers of adipocyte function. 
    • Rather than evaporating triglyceride-rich lipoproteins the body started storing them. 
  • The research found that when healthy men in their 20s got only 5 hours of sleep per night, their fat metabolism shifted. It found the chronic sleep restriction, or inadequate sleep, is associated with an increased risk of cardiometabolic disease.
