Hay fever (also called allergic rhinitis) affects 24% of Australians. Symptoms include sneezing, a runny nose (which may feel blocked or stuffy) and itchy eyes. People can also experience an itchy nose, throat or ears.

But COVID is still spreading, and other viruses can cause cold-like symptoms. So how do you know which one you’ve got?

Remind me, how does hay fever cause symptoms?

Hay fever happens when a person has become “sensitised” to an allergen trigger. This means a person’s body is always primed to react to this trigger.

Triggers can include allergens in the air (such as pollen from trees, grasses and flowers), mould spores, animals or house dust mites which mostly live in people’s mattresses and bedding, and feed on shed skin.

When the body is exposed to the trigger, it produces IgE (immunoglobulin E) antibodies. These cause the release of many of the body’s own chemicals, including histamine, which result in hay fever symptoms.

People who have asthma may find their asthma symptoms (cough, wheeze, tight chest or trouble breathing) worsen when exposed to airborne allergens. Spring and sometimes into summer can be the worst time for people with grass, tree or flower allergies.

However, animal and house dust mite symptoms usually happen year-round.

What else might be causing my symptoms?

Hay fever does not cause a fever, sore throat, muscle aches and pains, weakness, loss of taste or smell, nor does it cause you to cough up mucus.

These symptoms are likely to be caused by a virus, such as COVID, influenza, respiratory syncytial virus (RSV) or a “cold” (often caused by rhinoviruses). These conditions can occur all year round, with some overlap of symptoms:

COVID still surrounds us. RSV and influenza rates appear higher than before the COVID pandemic, but it may be due to more testing.

So if you have a fever, sore throat, muscle aches/pains, weakness, fatigue, or are coughing up mucus, stay home and avoid mixing with others to limit transmission.

People with COVID symptoms can take a rapid antigen test (RAT), ideally when symptoms start, then isolate until symptoms disappear. One negative RAT alone can’t rule out COVID if symptoms are still present, so test again 24–48 hours after your initial test if symptoms persist.

You can now test yourself for COVID, RSV and influenza in a combined RAT. But again, a negative test doesn’t rule out the virus. If your symptoms continue, test again 24–48 hours after the previous test.

If it’s hay fever, how do I treat it?

Treatment involves blocking the body’s histamine release, by taking antihistamine medication which helps reduce the symptoms.

Doctors, nurse practitioners and pharmacists can develop a hay fever care plan. This may include using a nasal spray containing a topical corticosteroid to help reduce the swelling inside the nose, which causes stuffiness or blockage.

Nasal sprays need to delivered using correct technique and used over several weeks to work properly. Often these sprays can also help lessen the itchy eyes of hay fever.

Drying bed linen and pyjamas inside during spring can lessen symptoms, as can putting a smear of Vaseline in the nostrils when going outside. Pollen sticks to the Vaseline, and gently blowing your nose later removes it.

People with asthma should also have an asthma plan, created by their doctor or nurse practitioner, explaining how to adjust their asthma reliever and preventer medications in hay fever seasons or on allergen exposure.

People with asthma also need to be alert for thunderstorms, where pollens can burst into tinier particles, be inhaled deeper in the lungs and cause a severe asthma attack, and even death.

What if it’s COVID, RSV or the flu?

Australians aged 70 and over and others with underlying health conditions who test positive for COVID are eligible for antivirals to reduce their chance of severe illness.

Most other people with COVID, RSV and influenza will recover at home with rest, fluids and paracetamol to relieve symptoms. However some groups are at greater risk of serious illness and may require additional treatment or hospitalisation.

For RSV, this includes premature infants, babies 12 months and younger, children under two who have other medical conditions, adults over 75, people with heart and lung conditions, or health conditions that lessens the immune system response.

For influenza, people at higher risk of severe illness are pregnant women, Aboriginal people, people under five or over 65 years, or people with long-term medical conditions, such as kidney, heart, lung or liver disease, diabetes and decreased immunity.

If you’re concerned about severe symptoms of COVID, RSV or influenza, consult your doctor or call 000 in an emergency.

If your symptoms are mild but persist, and you’re not sure what’s causing them, book an appointment with your doctor or nurse practitioner. Although hay fever season is here, we need to avoid spreading other serious infectious.

At this time of year many of us resolve to prioritise our health. So it is no surprise there’s a roaring trade of products purporting to guarantee you live longer, be healthier and look more youthful.

While an estimated 25% of longevity is determined by our genes, the rest is determined by what we do, day to day.

There are no quick fixes or short cuts to living longer and healthier lives, but the science is clear on the key principles. Here are five things you can do to extend your lifespan and improve your health.

1. Eat a predominantly plant-based diet

What you eat has a huge impact on your health. The evidence overwhelmingly shows eating a diet high in plant-based foods is associated with health and longevity.

If you eat more plant-based foods and less meat, processed foods, sugar and salt, you reduce your risk of a range of illnesses that shorten our lives, including heart disease and cancer.

Plant-based foods are rich in nutrients, phytochemicals, antioxidants and fibre. They’re also anti-inflammatory. All of this protects against damage to our cells as we age, which helps prevent disease.

No particular diet is right for everyone but one of the most studied and healthiest is the Mediterranean diet. It’s based on the eating patterns of people who live in countries around the Mediterranean Sea and emphases vegetables, fruits, wholegrains, legumes, nuts and seeds, fish and seafood, and olive oil.

2. Aim for a healthy weight

Another important way you can be healthier is to try and achieve a healthy weight, as obesity increases the risk of a number of health problems that shorten our lives.

Obesity puts strain on all of our body systems and has a whole myriad of physiological effects including causing inflammation and hormonal disturbances. These increase your chances of a number of diseases, including heart disease, stroke, high blood pressure, diabetes and a number of cancers.

In addition to affecting us physically, obesity is also associated with poorer psychological health. It’s linked to depression, low self-esteem and stress.

One of the biggest challenges we face in the developed world is that we live in an environment that promotes obesity. The ubiquitous marketing and the easy availability of high-calorie foods our bodies are hard-wired to crave mean it’s easy to consume too many calories.

3. Exercise regularly

We all know that exercise is good for us – the most common resolution we make this time of year is to do more exercise and to get fitter. Regular exercise protects against chronic illness, lowers your stress and improves your mental health.

While one of the ways exercising helps you is by supporting you to control your weight and lowering your body fat levels, the effects are broader and include improving your glucose (blood sugar) use, lowering your blood pressure, reducing inflammation and improving blood flow and heart function.

While it’s easy to get caught up in all of the hype about different exercise strategies, the evidence suggests that any way you can include physical activity in your day has health benefits. You don’t have to run marathons or go to the gym for hours every day. Build movement into your day in any way that you can and do things that you enjoy.

4. Don’t smoke

If you want to be healthier and live longer then don’t smoke or vape.

Smoking cigarettes affects almost every organ in the body and is associated with both a shorter and lower quality of life. There is no safe level of smoking – every cigarette increases your chances of developing a range of cancers, heart disease and diabetes.

Even if you have been smoking for years, by giving up smoking at any age you can experience health benefits almost immediately, and you can reverse many of the harmful effects of smoking.

If you’re thinking of switching to vapes as a healthy long term option, think again. The long term health effects of vaping are not fully understood and they come with their own health risks.

5. Prioritise social connection

When we talk about living healthier and longer, we tend to focus on what we do to our physical bodies. But one of the most important discoveries over the past decade has been the recognition of the importance of spiritual and psychological health.

People who are lonely and socially isolated have a much higher risk of dying early and are more likely to suffer from heart disease, stroke, dementia as well as anxiety and depression.

Although we don’t fully understand the mechanisms, it’s likely due to both behavioural and biological factors. While people who are more socially connected are more likely to engage in healthy behaviours, there also seems to be a more direct physiological effect of loneliness on the body.

So if you want to be healthier and live longer, build and maintain your connections to others.
