Hayfever or a summer cold? How to tell the difference

Every May the same question lands at our counter: 'Is this hayfever, or have I caught something?' The symptoms overlap enough to confuse, but a few patterns usually give it away.

Telling them apart

  • Itchy eyes, nose and throat → strongly suggests hayfever
  • Yellow or green mucus, body aches, fever → more likely a cold
  • Symptoms tied to time outdoors → hayfever
  • Symptoms lasting more than 10-14 days → hayfever or another allergy

What actually helps

Daily non-drowsy antihistamines started early in the season generally outperform reaching for them once symptoms flare. A steroid nasal spray adds further relief if eyes and nose are streaming. For severe or persistent allergy symptoms, our ALEX² Allergy Explorer blood test screens for 295 allergens in a single sample.
