Impacts of Sleep Deprivation:
🧠 Cognitive and Mental Health Impacts
Impaired memory and concentration: Reduces attention, problem-solving skills, and short-term memory.
Mood changes: Increases irritability, stress, and risk of depression and anxiety.
Reduced judgment and decision-making: Leads to impulsive behavior and poor choices.
Hallucinations (in extreme cases): Particularly with prolonged total sleep deprivation.
Increased risk of mental health disorders: Chronic sleep loss is linked to anxiety, depression, and even psychosis.
🏃♂️ Physical Health Effects
Weakened immune system: Increases susceptibility to illness.
Hormonal imbalance: Disrupts hormones that regulate hunger, growth, and stress (e.g., cortisol, ghrelin, leptin).
Increased risk of chronic diseases: Higher chances of obesity, type 2 diabetes, cardiovascular disease, and high blood pressure.
Reduced motor function: Slower reaction times and coordination, increasing risk of accidents and injuries.
🧬 Biological and Cellular Impact
Accelerated aging: Poor sleep affects cellular repair processes and may shorten telomeres (a marker of aging).
Disrupted metabolism: Alters glucose regulation and appetite control.
Impaired detoxification in the brain: Sleep helps clear out waste products like beta-amyloid, linked to Alzheimer’s disease.
