When teenagers sleep less than the recommended 8 hours, their performance across cognitive function, emotional regulation, physical health, and academic performance declines. Here's a rough estimate of how much functionality might be affected for each attribute per hour of sleep lost, based on research into sleep deprivation:
1. Memory, problem-solving, creativity
By missing just 1 hour of sleep, cognitive functions like memory and focus can drop by up to 15%, leading to difficulties in learning and retaining information.
2. Stress, mood swings, emotional stability
Each hour of sleep deprivation can reduce a teenager’s ability to manage stress and emotions by 15-20%, leading to increased irritability, anxiety, and mood swings.
3. Growth, immune function, physical recovery
For every hour lost, physical health declines by about 10-12%. This affects growth, muscle recovery, and immune function, making teens more susceptible to illness or injury.
4. Attention span, retention, decision-making
Academic performance can drop by 10-15% for every missed hour, as attention spans shrink, retention decreases, and decision-making ability weakens.
Overall Effect:
Each additional hour of sleep lost below 8 hours can reduce overall functioning by 10-15%. With just 5 hours of sleep, functionality could drop to 70-50%
