Poor Sleep Quality
You may sleep for 8 hours, but frequent disturbances and light sleep reduce recovery.

Vitamin Deficiencies
Low Vitamin D, B12 or iron levels can make you feel exhausted throughout the day.

Thyroid Imbalance
Underactive thyroid slows down metabolism, leading to fatigue even with proper rest.

High Stress Levels
Mental stress keeps your body in a “tired-but-alert” state, preventing deep rest.

Lack of Physical Activity
Being inactive actually makes you feel more tired, not more rested.
