Why do I get a headache from crying?

Question

Accepted Answer

Crying is physical work, and the headache after a proper cry is a tension headache with a clear supply chain. The NHS lists stress, sleep problems, and dehydration among the common causes of headaches, and a hard cry delivers all three: the emotional stress itself, the sustained muscle clenching that crying involves - jaw tight, brow furrowed, neck and scalp muscles contracted for minutes at a time - and genuine fluid loss through tears and sniffing, often on top of skipped meals and poor sleep around whatever prompted the tears. The NHS describes the result: pain on both sides of the head, a pressing or tightening band-like feeling, and a scalp that can feel tender to touch - the classic tension-headache signature, and the one most people recognise from post-cry afternoons. The blocked nose that comes with crying adds sinus pressure around the eyes and forehead, amplifying the throb. Treatment is kind and simple: water or a warm drink to replace the fluid, a normal dose of paracetamol if you want it, a warm flannel over the eyes and forehead to release the clenched muscles, and rest - ideally actual sleep, which resets the whole system. Fresh air helps the congestion. The headache of a hard cry should fade within hours. The patterns beyond simple crying: headaches arriving several times a week, a sudden worst-ever thunderclap headache (that one is an emergency), headache with a stiff neck, rash, or confusion, or a headache that follows a head injury. And if crying spells with headaches are becoming your daily normal, that pattern deserves a GP conversation about what is underneath - low mood and tension headaches travel together.
