- Improved cognitive function: Sleep enhances memory, attention, and decision-making abilities.
- Enhanced mood: Sleep deprivation can lead to irritability, anxiety, and depression.
- Boosted immune system: Sleep plays a crucial role in the body's immune response, helping us fight off infections.
- Reduced risk of chronic diseases: Lack of sleep is linked to an increased risk of heart disease, stroke, diabetes, and obesity.
