"Sleep Deprivation: Effects, Risks, and Importance"
- In 1965, 17-year-old Randy Gardner stayed awake for 264 hours, equivalent to 11 days, to study the effects of sleep deprivation. As the experiment progressed, he experienced deteriorating physical and mental functions, including loss of focus, touch identification, mood swings, coordination, concentration, memory issues, paranoia, and hallucinations.
- Sleep is crucial for overall health, with adults needing 7-8 hours and adolescents requiring about 10 hours of sleep per night. Lack of sleep can lead to hormonal imbalances, illness, and even death. Sleep-inducing chemicals like adenosine and melatonin signal the body to rest, entering non-REM sleep where DNA repair and bodily replenishment occur.
- Chronic sleep deprivation affects learning, memory, mood, reaction time, and can lead to serious health issues like inflammation, high blood pressure, hallucinations, diabetes, obesity, and increased stroke risk. Fatal Familial Insomnia, a rare genetic condition, prevents sleep and ultimately leads to dementia and death. The brain's glymphatic system clears waste products during sleep, highlighting the importance of adequate rest for overall well-being.
