Several factors can increase or decrease how much sleep you need:

Mental Demands: Cognitively demanding work or learning new skills can increase sleep needs to consolidate memories.

Health Conditions: Illness, injury, and chronic conditions often require more sleep for healing.

Sleep Quality: Poor quality sleep means you may need more total time in bed to feel rested.
