Bushfires are currently burning in Australian states including Victoria, Tasmania, Western Australia and South Australia. In some areas, fire authorities have warned residents about the presence of smoke.

Bushfire smoke is harmful to our health. Tiny particles of ash can lodge deep in the lungs.

Exposure to this type of smoke may worsen existing conditions such as asthma, and induce a range of health effects from irritation of the eyes, nose and throat to changes in the cardiovascular system.

Public health recommendations during smoke events tend to provide general advice, and don’t often include advice specifically geared at children. But children are not just little adults. They are uniquely vulnerable to environmental hazards such as bushfire smoke for a number of reasons.

Different physiology, different behaviour

Children’s lungs are still developing and maturing.

Airways are smaller in children, especially young children, which is associated with greater rates of particle deposition – when particles settle on the surfaces of the airways.

Children also breathe more air per kilogram of body weight compared with adults, and therefore inhale more polluted air relative to their size.

Further, children’s detoxification systems are still developing, so environmental toxins take longer to effectively clear from their bodies.

Meanwhile, children’s behaviour and habits may expose them to more environmental toxins than adults. For example, they tend to do more physical activity and spend more time outdoors. Higher levels of physical activity lead to more air inhaled per kilogram of body weight.

Also, a normal and important part of children’s early play is exploring their environment, including by putting things in their mouth. This can result in kids ingesting soil, dust and dirt, which often contain environmental contaminants.

For these reasons, it’s important to consider the specific needs of children when providing advice on what to do when there’s smoke in the air.

Keeping our environments healthy

The Australian government offers recommendations for minimising the health risks from exposure to bushfire smoke. The main advice includes staying indoors and keeping doors and windows closed.

This is great advice when the smoke is thick outside, but air pollutants may still accumulate inside the home. So it’s important to air your home once the smoke outside starts to clear. Take advantage of wind changes to open up and get air moving out of the house with a cross breeze.

Kids are natural scientists, so get them involved. For example, you and your child can “rate” the air each hour by looking at a landmark outside your home and rating how clearly you can see it. When you notice the haze is reducing, open up the house and clear the air.

Because air pollutants settle onto surfaces in our home and into household dust, an easy way to protect kids during smoky periods is to do a daily dust with a wet cloth and vacuum regularly. This will remove pollutants and reduce ingestion by children as they play. Frequent hand washing helps too.

Healthy bodies and minds

Research exploring the effects of bushfire smoke exposure on children’s health is sparse. However, during smoke events, we do see an increase in hospital visits for asthma, as well as children reporting irritation to their eyes, nose and throat.

If your child has asthma or another medical condition, ensure they take any prescribed medications on a regular schedule to keep their condition well controlled. This will minimise the risk of a sudden worsening of their symptoms with bushfire smoke exposure.

Make sure any action plans for symptom flare-ups are up to date, and ensure you have an adequate supply of in-date medication somewhere easy to locate and access.

Kids can get worried during bushfires, and fire emergencies have been linked with a reduction in children’s mental health. Stories such as the Birdie’s Tree books can help children understand these events do pass and people help one another in times of difficulty.

Learning more about air pollution can help too. Our group has a children’s story explaining how air pollution affects our bodies and what can help.

It’s also important for parents and caregivers not to get too stressed, as children cope better when their parents manage their own anxiety and help their children do the same. Try to strike a balance between being vigilant and staying calm.

What about masks?

N95 masks can protect the wearer from fine particles in bushfire smoke, but their use is a bit complicated when it comes to kids. Most young children won’t be able to fit properly into an N95 mask, or won’t tolerate the tight fit for long periods. Also, their smaller airways make it harder for young children to breathe through a mask.

If you choose to use an N95 mask for your children, it’s best to save them for instances when high-level outdoor exposure is unavoidable, such as if you’re going outside when the smoke is very thick.

N95 masks should be replaced after around four hours or when they become damp.

If your child has an existing heart or lung condition, consult their doctor before having them wear an N95 mask.

Our team is currently recruiting for a study exploring the effects of bushfire smoke in children. If you live in south east Queensland and are interested in participating in the event of a bushfire or hazard reduction burn near your home, please express your interest here.

Research out today from Finland suggests women may find it harder to adjust to later-life divorce and break-ups than men.

The study used population data from 229,000 Finns aged 50 to 70 who had undergone divorce, relationship break-up or bereavement and tracked their use of antidepressants before and after their relationship ended.

They found antidepressant use increased in the four years leading to the relationship dissolution in both genders, with women experiencing a more significant increase.

But it’s too simplistic to say women experience poorer mental health or tend to be less happy after divorce than men.

Remind me, how common is divorce?

Just under 50,000 divorces are granted each year in Australia. This has slowly declined since the 1990s.

More couple are choosing to co-habitate, instead of marry, and the majority of couples live together prior to marriage. Divorce statistics don’t include separations of cohabiting couples, even though they are more likely than married couples to separate.

Those who divorce are doing so later in life, often after their children grow up. The median age of divorce increased from 45.9 in 2021 to 46.7 in 2022 for men and from 43.0 to 43.7 for women.

The trend of late divorces also reflects people deciding to marry later in life. The median duration from marriage to divorce in 2022 was around 12.8 years and has remained fairly constant over the past decade.

Why do couples get divorced?

Changes in social attitudes towards marriage and relationships mean divorce is now more accepted. People are opting not to be in unhappy marriages, even if there are children involved.

Instead, they’re turning the focus on marriage quality. This is particularly true for women who have established a career and are financially autonomous.

Similarly, my research shows it’s particularly important for people to feel their relationship expectations can be fulfilled long term. In addition to relationship quality, participants reported needing trust, open communication, safety and acceptance from their partners.

“Grey divorce” (divorce at age 50 and older) is becoming increasingly common in Western countries, particularly among high-income populations. While factors such as an empty nest, retirement, or poor health are commonly cited predictors of later-in-life divorce, research shows older couples divorce for the same reasons as younger couples.

What did the new study find?

The study tracked antidepressant use in Finns aged 50 to 70 for four years before their relationship breakdown and four years after.

They found antidepressant use increased in the four years leading to the relationship break-up in both genders. The proportion of women taking antidepressants in the lead up to divorce increased by 7%, compared with 5% for men. For de facto separation antidepressant use increased by 6% for women and 3.2% for men.

Within a year of the break-up, antidepressant use fell back to the level it was 12 months before the break-up. It subsequently remained at that level among the men.

But it was a different story for women. Their use tailed off only slightly immediately after the relationship breakdown but increased again from the first year onwards.

The researchers also looked at antidepressant use after re-partnering. There was a decline in the use of antidepressants for men and women after starting a new relationship. But this decline was short-lived for women.

But there’s more to the story

Although this data alone suggest women may find it harder to adjust to later-life divorce and break-ups than men, it’s important to note some nuances in the interpretation of this data.

For instance, data suggesting women experience depression more often than men is generally based on the rate of diagnoses and antidepressant use, which does not account for undiagnosed and unmedicated people.

Women are generally more likely to access medical services and thus receive treatment. This is also the case in Australia, where in 2020–2022, 21.6% of women saw a health professional for their mental health, compared with only 12.9% of men.

Why women might struggle more after separating

Nevertheless, relationship dissolution can have a significant impact on people’s mental health. This is particularly the case for women with young children and older women.

So what factors might explain why women might experience greater difficulties after divorce later in life?

Research investigating the financial consequences of grey divorce in men and women showed women experienced a 45% decline in their standard of living (measured by an income-to-needs ratio), whereas men’s dropped by just 21%. These declines persisted over time for men, and only reversed for women following re-partnering.

Another qualitative study investigating the lived experiences of heterosexual couples post-grey divorce identified financial worries as a common theme between female participants.

A female research participant (age 68) said:

[I am most worried about] the money, [and] what I’m going to do when the little bit of money I have runs out […] I have just enough money to live. And, that’s it, [and if] anything happens I’m up a creek. And Medicare is incredibly expensive […] My biggest expense is medicine.

Another factor was loneliness. One male research participant (age 54) described he preferred living with his ex-wife, despite not getting along with her, than being by himself:

It was still [good] knowing that [the] person was there, and now that’s gone.

Other major complications of later-life divorce are possible issues with inheritance rights and next-of-kin relationships for medical decision-making.

Separation can be positive

For some people, divorce or separation can lead to increased happiness and feeling more independent.

And the mental health impact and emotional distress of a relationship dissolution is something that can be counterattacked with resilience. Resilience to dramatic events built from life experience means older adults often do respond better to emotional distress and might be able to adjust better to divorce than their younger counterparts.
