What causes the body to feel drain?

Feeling drained can be caused by various factors, including inadequate sleep, poor nutrition, dehydration, and excessive physical or mental stress. Health conditions such as anemia, thyroid disorders, or chronic fatigue syndrome can also contribute to fatigue. Additionally, emotional stress or anxiety can sap energy levels, leading to a feeling of exhaustion. Addressing these factors through lifestyle changes, proper hydration, and medical consultation can help restore energy levels.
