For how we live.
For hay fever and year-round allergy, the pill most people reach for is not the strongest option. A meta-analysis found steroid nasal sprays beat oral antihistamines across nasal symptoms — most of all a blocked nose.
Saline nasal irrigation has better evidence than most self-care remedies: trials support it for chronic sinus and hay-fever symptoms, and a pilot found it shortened colds. The catch is that the quality is low.
A detection-and-attribution study across 60 pollen stations found seasons 20 days longer and concentrations 21% higher since 1990 — and separated how much of that trend is anthropogenic.
A randomised trial gave one group unfiltered local honey and found no relief beyond placebo. A later trial found a benefit — using a dose of about 70 grams a day alongside an antihistamine.
A European task force argued the first-generation drugs sold over the counter should not be. On symptom relief the newer ones differ from each other too — and the most familiar performed worst.
A 160-study meta-analysis found real but moderate symptom reductions while patients are on treatment. The evidence for lasting benefit after stopping is much thinner, and rests mainly on grass.
