Sun-Induced Headaches

What Causes Headaches In The Sun?

Headaches in the sun can have various causes, ranging in severity from 'very minor' to 'worrying'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose headaches in the sun, we could:
  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "headaches in the sun" as a symptom.  Here are two possibilities:
  • EFA Need
  • Heat Exhaustion

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
shoulder tightness
brittle fingernails
thin cracked heel calluses
type 2 diabetes NIDD
history of cysts in breasts
aspirin is effective pain reliever
history of adult acne
some ear wax build up
hydrogenated fat consumption
fatty food craving
leg cramps caused by walking
... and so on

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of headaches in the sun:
Cause Probability Status
Heat Exhaustion 98% Confirm
EFA Need 73% Possible
* This is a simple example to illustrate the process
