Hi
the cold sensation in the head linked to emotional or sensory triggers, along with fatigue and occasional word-finding difficulty could be the lingering effects of both anxiety recovery and
vitamin D deficiency. During anxiety or post-anxiety recovery, the nervous system often stays in a mildly hypervigilant state. Emotional cues, music, or deep thoughts can activate subtle bodily sensations what we call residual somatic anxiety. This can cause temperature-like sensations, tingling, or odd body awareness even without visible symptoms.
At the same time, a vitamin D3 level below 5 is severely deficient and can significantly affect mood, cognitive clarity, and fatigue. Even with supplementation, it takes 8–12 weeks for levels to normalize and the brain to regain full energy and focus. Spending too much time indoors and on screens adds to this fatigue and mental dullness. Recovery will be smoother if you reintroduce sunlight exposure (15–20 minutes daily), light exercise, structured breaks from screens, and calming practices like breathing or grounding. If symptoms persist beyond 2 months despite these changes, consider a neurological review to rule out post-anxiety fatigue or mild cognitive slowness.
