From menopause to mood lighting: The biggest health lessons of 2024

By Lauren Ironmonger and Sarah Berry

As we prepare to bid farewell to another year, it’s a good time to pause and reflect on what we’ve learnt.

So whether you’ve already picked up a few of these habits or are looking live better in the new year, we’ve rounded up the biggest things we learned about our health in 2024 – and what the experts had to say about them.

We need to pay more attention to women’s health

In 2024, conversations about women’s health moved further into the mainstream. Historically, most scientific research has studied male subjects, meaning most of what we know about how our bodies work is based on men. But this is starting to change.

Intermittent fasting has become a fashionable diet in recent years. But an emerging body of research suggests there are sex differences in metabolism that allow women to maintain energy reserves for reproduction when food supplies are low. What this means is that fasting affects women differently from men, and fasted training may not be beneficial for women of a normal weight.

And while it’s common knowledge that movement is important at every stage of life, conventional wisdom is that we should slow down the older we get. But for people going through menopause, the opposite may be true. According to some experts, two types of exercise are most beneficial to menopausal women: high-intensity interval training (HIIT) and sprint interval training (SIT).

Mood lighting: in. Overhead lights: out

It’s the backdrop of our lives, and yet in 2024 light came into focus. We began to see clearly its impact on our health.

Professor Sean Cain thinks we might one day think of the way we use light in the same way we now think of smoking.

And that is because his research has found that poor light patterns – bright light at night and dim light during the day – increased the risk of premature death by 30 per cent, and Type 2 diabetes by as much as 40 per cent.

On the flip side, it was found that greater exposure to daytime light seems to have a protective effect on our mental health and is associated with a lower risk of depression, anxiety and other disorders. Why? Light sets the time on our circadian clock. When our biological and behavioural rhythms are out of alignment, our systems are more prone to malfunction.

The trick is to get sunlight as soon as we wake up, try to get natural or bright light during the day, and dim the lights as the sun goes down.

Ozempic

Ozempic was the word on the tip of every celebrity’s tongue this year. Semaglutide, the generic name for drugs like Ozempic, is being increasingly prescribed and used for weight loss, but we’re still learning about its long-term effects.

What we do know is that those on Ozempic need to maintain a healthy lifestyle, particularly one focused on maintaining bone density and muscle mass. Such medication can also wreak havoc on the gastrointestinal system, and the short-term weight loss they can cause can be detrimental to health.

And as demand for weight-loss drugs increases, a swath of “natural”, copycat Ozempic supplements have cropped up.

The year of contrast exercise

There is no best way to move except whatever gets you moving. But 2024 was the year of contrast exercise.

In reaction to the pedal to the metal exercise culture, people embraced gentler forms of exercise and the ability to change gears.

That means yoga or Pilates and longer, slower forms of exercise that can be maintained for longer periods, such as brisk walking or jogging, hiking, easy cycling, rowing or swimming.

It also means, shifting up a few gears several times a week with some high intensity interval training, sprint interval training or lifting heavy weights.

The trend reflects the knowledge that our bodies need different types of movement. Longer, slower exercise builds endurance, burns fat and offsets the risk of injury while the short hits of high intensity boost our cardiorespiratory fitness, muscle strength and power.

The sober curious movement continues to grow

The trend of people reducing their alcohol intake – or ditching it entirely – will continue into 2025 as public awareness of the social, mental and physical effects of booze continues to grow. As a sign of this changing tide, some large corporations are banning workplace drinking while politicians including Barnaby Joyce are speaking up about going sober.

In August, a large study from Britain found that even light drinking was associated with an increase in cancer deaths in older adults, while more women are standing up against “mummy wine culture”.

Alcohol companies, of course, are taking note of this change too by expanding their offerings to include non-alcohol drinks. They’re also trying to capture health-conscious drinkers with low-sugar and low-carb options, but experts warn there’s “no such things as a healthy beer”.

Plastic, not fantastic

This was the year many of us started to question the non-stick pans we cook with, the half-melted black spatulas and other greaseproof, waterproof and plastic products in our lives.

Earlier this year investigative reporter Carrie Fellner won a Walkley Award for her reporting on the unfolding environmental and health crisis resulting from “forever chemicals” known as PFAS.

PFAS are in our water supply, but also in our kitchens, our clothes, our furniture, cosmetics, sunscreens, shampoos, carpets, furniture, food packaging, menstrual products, dental products, and even in artificial turf.

Separate research found single-use plastics leach chemicals and shed microplastics into our environment. Chemical exposure increases if plastic is heated, and black plastic may pose a specific danger.

Instead, use glass or metal water bottles and containers; opt for cast iron, stainless steel or PFAS-free non-stick pans, reheat food on a ceramic plate or bowl; switch out plastic utensils for wood or stainless steel; and keep your home clean and well-ventilated.
