Fatigue and exhaustion

Are you getting enough sleep but still feel tired and exhausted? If this symptom occurs more often during the colder seasons, a vitamin D deficiency could be to blame. It's best to clear this up with your doctor and possibly get a prescription for nutritional supplements. Once the deficiency is corrected, your symptoms should disappear.
