I often experience aches in summer and feel lethargic, especially in the morning. Should I retest for vitamin D deficiency?
Aches and morning lethargy during summer can be caused by factors such as dehydration, heat exhaustion, or poor sleep, and not necessarily by a vitamin D deficiency. However, since low vitamin D levels can also cause these symptoms, you should discuss retesting your blood levels with your doctor. If your levels are low, your doctor will recommend the appropriate supplements.
