Intro to Sleep
This natural cycle, regulated by the suprachiasmatic nucleus, acts as the body’s internal clock, controlling sleep and wakefulness.
What is the circadian rhythm?
This theory proposes that sleep helps conserve energy by reducing metabolism and body temperature.
What is the Energy Conservation Theory?
During sleep, the body releases proteins that help fight infections and reduce inflammation.
What is the immune system?
White noise, brown noise, rain sounds, and ocean waves 🌊
What are the four sleep sounds we discussed?
During this stage of sleep, also known as "deep sleep," the body repairs tissues, grows muscles, and strengthens the immune system.
What is Stage 3?
This theory highlights sleep’s role in the brain’s reorganization and memory storage, particularly during childhood development.
What is the Brain Plasticity Theory?
By regulating hunger hormones, quality sleep supports this crucial aspect of maintaining a healthy body.
What is weight management?
Limiting screen time 1–2 hours before bed helps reduce exposure to this type of light, which disrupts natural sleep hormones.
What is blue light?
This small endocrine structure, situated deep in the brain, is responsible for releasing the hormone that spikes in the evening to signal the onset of sleep, playing a critical role in aligning the circadian rhythm with environmental cues.
What is the pineal gland?
This part of the brain, responsible for emotional regulation, shows deficits in function when we are sleep-deprived.
What is the amygdala?
Sleep deprivation and this mental health condition have a cyclical relationship, where one exacerbates the other.
What are anxiety and insomnia?
To avoid disrupting sleep patterns during daylight saving time, prioritize this activity during the day.
What is getting sunlight exposure?
This brain cleaning system, active during deep sleep, clears out toxins like beta-amyloid to reduce the risk of neurodegenerative diseases.
What is the glymphatic system?
This scientist expanded the Restoration Theory to suggest that NREM sleep supports bodily recovery, while REM sleep supports brain recovery.
Who is Dr. Ian Oswald?
Over time, insufficient sleep contributes to the buildup of beta-amyloid plaques, a hallmark of this degenerative brain disease.
What is Alzheimer’s disease?
This range of room temperature is recommended by experts and is considered ideal for optimal sleep quality.
What is 16–19°C?
