The hay fever season can run from late February to October
WILL THIS BE A BAD YEAR FOR HAY FEVER?
That every one is dependent upon the climate. Usually, rain dissipates pollen, however in dry situations it blows straight into the air, the place it could then simply get into the eyes and nostril.
What we do know for positive is that pollen seasons are getting longer. A US research revealed in February discovered that the pollen season prolonged by 30 days between 1990 and 2018
So as an alternative of beginning in March and ending in September, it’s now beginning in late February, and persevering with into October.
WHY ARE SYMPTOMS WORSE SOMETIMES?
Hay fever signs are typically worst round 11am and 6pm, and it is because pollen is at nostril stage, says Dr Adrian Morris, a specialist primarily based on the Surrey Allergy Clinic.
“Pollen begins off on the bottom at the start of the day, so at 8am the pollen is all sitting on the grass,” he says.
“Because the day warms up, the grass additionally warms and the pollen particles are shed and stand up within the air.
“At about 11am, they’re at nostril stage – round 5ft off the bottom. Throughout the course of the day, the pollen then goes very excessive up into the environment and, because it cools down through the course of the day, the pollen grains come right down to earth once more and at about 6pm they are typically again at nostril stage.
“That is why there are two occasions of the day when individuals are typically significantly weak.”
Watch the climate forecast. Light rain can ease signs as a result of it washes the pollen out of the air and on to the bottom, out of hurt’s method.
However throughout a thunderstorm, the pollen grains can explode into smaller particles, which may penetrate deeper into the airways and so exacerbate signs.
Light rain adopted by nonetheless, sunny climate creates the right situation for a pollen ‘bomb’ – a large surge of pollen.
The rain feeds the manufacturing of pollen, the nice and cozy climate triggers its launch and the shortage of wind retains it hanging within the air.
A sizzling, sunny day with little wind may also be an issue as a result of pollen stays airborne for longer.
Hay fever signs are typically worst round 11am and 6pm
CAN ADULTS DEVELOP HAY FEVER?
A latest survey by Allergy UK discovered practically half of individuals questioned mentioned that they had suffered hay fever for the primary time prior to now 5 years.
Whereas it normally begins in childhood, adults can immediately be affected, says Dr Kariyawasam: “Mostly, those that are genetically liable to allergy symptoms begin with eczema in infanthood, with hay fever then following in adolescence.”
It takes time for the immune system to turn out to be delicate to pollen, so most individuals aren’t struck down with hay fever for the primary time till they’re between 18 and 25, explains Professor Adam Fox, a guide in allergy symptoms at Evelina London Youngsters’s Hospital.
It is nonetheless doable to develop hay fever in your 30s or 40s however it might be uncommon to be a first-time sufferer in your 60s or 70s as a result of the immune response wanes with age.
IS IT HAY FEVER – OR DO I HAVE COVID?
There’s some crossover with the signs of Covid and hay fever, says Dr Kariyawasam. “With each you will get flu-like signs – and consequently some individuals with hay fever really feel they only need to go to mattress, simply as these with Covid could.”
However whereas a excessive temperature is likely one of the defining signs of catching coronavirus, hay fever doesn’t trigger a fever, provides Dr Morris.
Whereas the immune response to a virus generates chemical substances that trigger a fever, a special a part of the immune system is triggered with allergy symptoms and this doesn’t embrace fever-generating chemical substances.
It may possibly take just a few days for antihistamines to take impact, so begin them round three days earlier than you count on hay fever signs to start

IS IT WORSE IN THE COUNTRY?
That is one other delusion, says Dr Morris. “Many individuals do not realise there’s a increased proportion of hay fever victims in cities than within the countryside.”
Elevated air air pollution could also be guilty, particularly particulates (microscopic particles) from diesel fumes, for triggering the situation and exacerbating hay fever in those that have it.
A research revealed final 12 months within the Journal of Allergy and Medical Immunology discovered that individuals who dwell in areas of upper air pollution usually tend to have extra extreme nasal signs.
Individuals who have already got allergy symptoms are more likely to have worse signs if they’re in a polluted setting, says Professor Sir Malcolm Inexperienced, founding father of the British Lung Basis.
“There’s additionally proof that individuals who wouldn’t usually develop allergy symptoms are tipped over into changing into allergic due to mucosal irritation attributable to pollution,” he provides.
Canine can get hay fever too. Wiping their fur and paws after a stroll is a good suggestion
WHEN SHOULD I START TAKING MEDICATION?
If you recognize you undergo from hay fever, take motion upfront, says pharmacist Sultan Dajani.
“It may possibly take just a few days for antihistamines to take impact, so begin them round three days earlier than you count on signs to start.
“Within the meantime, you need to use corticosteroid nasal sprays, similar to mometasone furoate [brand name Nasonex] or fluticasone propionate [Flonase], accessible over-the-counter, to override a few of the signs till the antihistamine begin working correctly.”
These cut back native irritation and are completely different from decongestants, which may help relieve stuffiness however should be stopped after three days as a result of they’ll trigger “rebound rhinitis”.
“When you preserve taking them, you turn out to be tolerant, the medicine does not work any extra and also you get the signs again however worse than earlier than.”
Lotions containing an antihistamine may help cut back urticaria (pores and skin rashes) attributable to hay fever.
Eye drops containing sodium cromoglicate (similar to Optrex) may help with pink, itchy eyes by decreasing the discharge of histamine and can be utilized as much as 4 occasions a day.
WHY DO I GET DROWSY ON ANTIHISTAMINES?
Antihistamines connect to histamine receptors and block the chemical histamine, which is launched as a part of an allergic response and causes itchy eyes and sneezing.
Medicines similar to chlorphenamine could cause drowsiness as a result of they cross into the mind, the place they have an effect on sleep and wakefulness, says Sultan Dajani.
“Newer antihistamines similar to cetirizine, loratadine and fexofenadine do not cross into the mind and so do not trigger drowsiness – though, consequently, they might be barely much less efficient.”
Carrying a face masks and wraparound sun shades may help minimise hay fever signs
SHOULD I PUT VASELINE AROUND MY NOSTRILS?
Sultan Dajani suggests ignoring the widespread recommendation to smear petroleum jelly round your nostril to ‘catch’ the pollen grains earlier than their enter your nostril: “It’s inhaling pollen that is the issue and this may not cease this. It should simply make a sticky mess.”
However there might be some profit, says Dr Morris. “When somebody has hay fever, the nostril might be very itchy and irritated from fixed sneezing. Rubbing on a layer of petroleum jelly can shield towards this.”
Extra helpful is a face masks and wraparound sun shades. “Odd [surgery-style] blue masks will act as a barrier and cut back the variety of pollen grains getting into your nostril and mouth – though not utterly because the pollen particles are very small,” says Sultan Dajani.
WILL I GROW OUT OF HAY FEVER?
Sure you may – signs sometimes begin to enhance from the age of 40 onwards, says Dr Kariyawasam.
That is as a result of signs start when immune cells referred to as B lymphocytes mistakenly determine the proteins on pollen as a menace and make antibodies in response.
These antibodies (often known as IgE) bind to mast cells, triggering the discharge of histamine, which tries to rid the physique of the menace, inflicting signs similar to sneezing and watering eyes.
“Nonetheless, as we become old we produce much less IgE,” says Dr Kariyawasam. “I at all times say 40 is a turning level for this, however for most individuals signs considerably enhance after 60.”
YOUR PET CAN GET HAY FEVER, TOO
“Canine and cats can get hay fever when uncovered to grass and tree pollen, identical to their homeowners,” says Daniella Dos Santos, senior vice chairman of the British Veterinary Affiliation and a small-animal vet in Buckinghamshire.
“Their signs are typically completely different: the primary symptom is itchy pores and skin. Canine with hay fever are additionally liable to ear infections.”
That can assist you and your pet, the animal charity Blue Cross suggests wiping your canine’s fur, pores and skin and paws with a humid material to take away pollen after a stroll, washing bedding usually and maintaining your garden well-mown – quick grass releases much less pollen.
Research have discovered that consuming regionally produced honey throughout hay fever season could reduce signs
HOW DIET MAY HELP WITH SYMPTOMS…
There’s some preliminary analysis suggesting that probiotics (dwell, ‘pleasant’ micro organism) could assist alleviate hay fever signs.
Prof Adam Fox says: “The considering is that the best way that our immune system responds to the skin world is sort of considerably influenced by the microbiome, the micro organism that colonise our intestine.
“So you probably have a ‘wholesome’ microbiome, it skews your immune system to extra applicable responses and fewer allergic responses, whereas you probably have an ‘unhealthy’ microbiome it could skew you the opposite method.
“However it’s early days and there aren’t any clinically related randomised trials to point out probiotics could assist.”
Nonetheless, some dietary methods could assist. Dietitian Carrie Ruxton says: “A method of serving to to calm the immune response is by having extra omega-3 fat as these are anti-inflammatory.
“Good sources are salmon, trout, mackerel and prawns.
“Research recommend consuming native honey each day throughout hay fever season could reduce signs.”
