Episode notes
Sleep and Gene Expression
- Sleep deprivation alters gene activity, affecting over 700 genes related to immune function, inflammation, and stress.
- Just one week of six hours' sleep can cause epigenetic changes in roughly 3% of the human genome.
Prioritizing Sleep
- Prioritize better sleep now, even with past deprivation, as it's never too late to improve sleep habits.
- Correcting sleep can positively impact cognitive decline and other health factors.
Sleep and Appetite
- Sleep deprivation dysregulates appetite hormones, decreasing leptin (satiety) and increasing ghrelin (hunger).
- This hormonal imbalance can lead to increased caloric intake and weight gain.
