Can crying cause a fever?

Yes, intense crying can temporarily raise body temperature due to physical exertion, but it shouldn't cause a real infection-like fever. Keep them calm and hydrated, and check their temperature again in an hour.

Deep emotional distress and crying can definitely disturb the body's natural energy and cause a temporary rise in warmth. Please sit in a quiet space, take slow deep breaths, and drink some cool water to calm your system. Let your mind rest, and consult a doctor if the fever persists.

Just like how stress and crying can spike my blood sugar levels temporarily, it can also raise body temperature slightly due to stress hormones. However, if the thermometer shows a high reading, it might be an actual bug. Don't self-medicate, get a proper medical opinion.

In my long life, I have seen many children get flushed and warm after a major tantrum or crying spell. This is just temporary physical heat from the exertion, not a true illness. Wash their face with cool water and let them rest, they will be back to normal soon.

I can only speak from my own experience with my toddler. Whenever she has a massive crying fit, her face gets bright red and her forehead feels very hot to the touch, but it usually goes away once she calms down and gets some fresh air. If it lasts longer, I always call our doctor.
