1. Increase Alertness
Short rest can improve cognitive functioning and alertness, resulting in a 30% decline in attention failures from baseline measure.

2. Reduce The Risk Of Cardiovascular Disease
Systematic midday napping (at least 3 times per week) is associated with a 37% lower risk of coronary heart disease.

3. Boost Productivity
Lack of sleep causes workers to perform at subpar levels. Harvard researchers estimate that sleep deprivation costs US companies $63 billion in lost productivity per year.

4. Enhance Learning
Even an ultra short period of sleep is sufficient to enhance memory processing.

5. Reduce Stress
Daytime napping stops or even reverses the process of deterioration in visual perception, thus helping individuals cope with information overload.

6. Improve Mood
Naps improve performance level and self-confidence of task performance.
