More Purposes Of Sleep
The second purpose of sleep is memory consolidation, the process that maintains and strengthens long term memory. Insufficient or fragmented sleep can hamper your ability to form both concrete memories (facts and figures) and emotional memories.
Finally, sleep is paramount for metabolic health. Studies have shown that when you sleep 5.5 hours per night instead of 8.5 hours per night, a lower proportion of the energy you burn comes from fat, while more comes from carbohydrate and protein. Insufficient sleep can lead to heart disease and diabetes.
