Lack of sleep triggers a cascade of effects on your body and mind, from immediate cognitive fog to long-term health risks like heart disease and diabetes.

Short-Term Impacts

  • Trouble concentrating or learning new info.
  • Emotional swings, from impatience to depression-like lows.
  • Reduced coordination, upping injury odds at work or driving.

Long-Term Health Risks

Central Nervous| Impaired memory, creativity, judgment| Microsleeps, poor focus
Immune & Metabolic| Altered hormones, inflammation| Diabetes, obesity, infections
