How long does hay fever last?

Considered one of the most common allergies in the UK, hay fever, also known as allergic rhinitis, affects approximately 13 million people in the UK alone. Although relatively low-risk, hay fever can be considerably debilitating for sufferers and can significantly impact their quality of life, but how long does hay fever actually last?

If you’re in the dark about the longevity of this common allergy, then today you should find everything you need to know about what to expect, how to tackle your symptoms and be prepared for summer.

What is hay fever?

Most of us will have heard of hay fever, but you may not know what it means or how it affects the body. In short, hay fever is an allergic reaction to pollen or dust. When inhaled, they irritate the mucus membranes found in the eyes and nose, causing inflammation and leading to a range of symptoms.

Typically, hay fever is at its worst between the months of May and September, as these tend to be the hottest months when the pollen count is at its highest.

What are the symptoms of hay fever?

The severity of your allergies will determine how much you suffer; however, the following are the most common signs of hay fever are:

• Congestion
• Coughing
• Fatigue
• Itchy and watery eyes
• Runny nose
• Sinus pressure
• Sore and swollen under-eyes

Can hay fever be serious?

Hay fever is not considered a serious allergy; however, in the most severe cases, it can lead to other health complications that may require further treatment. Some of these include:

• Worsening asthma
• Lack of sleep or insomnia
• Sinusitis
• Ear infections
• Reduced quality of life

Who can hay fever affect?

Unfortunately, hay fever can affect anyone, regardless of age, gender, or health status.

When does hay fever kick in?

Although it is possible to suffer the signs and symptoms of hay fever all year-round, the chances are that you will find your allergies flare up most during the spring and summer months. This is because tree pollen, grass pollen, dust mites and pet dander are often at their highest during this time.

How long does hay fever last?

Unfortunately, there is no guaranteed timeframe for hay fever symptoms. How long your hay fever lasts really depends on a variety of factors, including your level of exposure to allergens, the type of weather at the time, whether you are actively treating your symptoms and the type of pollen you are allergic to.

As a general guide, tree pollen lasts the longest. Tree pollen allergies can begin as early as February and last until June.

Grass and weed pollen typically last for a shorter period and peak during the summer. Allergies to grass pollen start from May and last until June, while symptoms caused by weed pollen can occur from June to September.

Typically, the severity of symptoms fluctuates from week to week or month to month, depending on pollen levels; however, in general, hay fever can last anywhere from a few weeks to a few months.

It is also important to note that everyone is different. While some may suffer mild irritation, others can find hay fever to be incredibly debilitating and may find little relief from medications. In general, however, most people find that their hay fever symptoms ease up as they get older, with around 10-20% of sufferers reporting their symptoms completely disappear after several years.

How can you reduce your hay fever symptoms?

While there is no cure for hay fever, there are some things you can do to reduce the severity of your symptoms:

• Seek advice from your pharmacy or doctor. There is a range of over-the-counter antihistamines which can help, or your GP may prescribe medication in more severe cases or when other treatments haven't worked.
• Keep a close eye on the pollen count.
• Refrain from going outdoors during a high pollen count.
• Have a shower and change your clothes after being outdoors to remove any pollen that has attached to you.
• Wearing wraparound sunglasses when outdoors protects your eyes from exposure to pollen.
• Applying Vaseline (petroleum jelly) around the nasal passages can help trap pollen and prevent an excessively runny nose.

Things to avoid during high pollen season:

• Cutting the grass
• Walks through fields
• Fresh flowers indoors
• Drying clothes outside
• Having a lot of contact with pets (typically, cats and dogs carry a lot of pollen in their fur when they have been outside)

The bottom line on hay fever

While incredibly irritating and inconvenient, hay fever usually won’t pose any major threat to your general health, but we understand it can certainly make life difficult during peak seasons.

To help combat the unwelcome signs of hay fever, it is helpful to come prepared with an effective and fast-acting treatment, such as the Nasonex intranasal treatment spray or Neoclarityn tablets. These types of medicines can offer relief when you need it most and help clear the airways during those more challenging days.

For itching and watery eyes (allergic conjunctivitis) caused by hay fever, eye drops are available from pharmacies, such as Murine Hayfever Relief and Optrex Hayfever Relief. These eye drops can help reduce irritation, redness, and tearing, which are commonly associated with hay fever.
