It’s 6:45 on a cold and rainy Tuesday morning. The alarm blares. As you begin to wake and wonder how it could possibly be morning already, your good intentions dawn on you. It’s run morning – and it’s the last thing you want to do. As you roll over to hit the snooze button, your mind scrambles for a valid excuse.
Why bother trying to be healthy? We all have to die of something, right?
In part this is true. Regardless of our discomfort with death, we all have to die sometime, and we all have to die from something. However, this is where the truth ends.
And when you look more deeply at what ill-health brings, it’s not just death that makes the strongest case for getting out of bed.
Today in Australia, the are mostly preventable – or at least can be significantly delayed. Factors like poor diet and tobacco drive ailments including heart disease, stroke, diabetes (type 2), lung disease and cancers. And when you look more deeply at what ill-health brings, it’s not just death that makes the strongest case for getting out of bed.
You’ll die later
Sure you have to die of something, but you may not have to die so soon. suggests having a healthier lifestyle even at age 50 is associated with a four to seven year longer life expectancy.
Even , improving lifestyle factors can benefit longevity. Avoiding an unhealthy weight, not smoking, maintaining a social network and engaging in leisure activities around age 75 sees a whopping five years added to a woman’s and six years added to a man’s life span.
You’ll be healthier, longer
Trying to be as healthy as you can is not just about adding more years to your life, but adding healthy years, or even decades. Populations who follow healthy forms of behaviour show a , in addition to a 70% reduction in type 2 diabetes, heart disease and stroke when compared with unhealthier peers. Studies also find live longer without disability than those who are overweight or smoke.
Trying to be as healthy as you can is not just about adding more years to your life, but adding healthy years, or even decades.
A significant proportion of octogenarians are also , more active lives. This is seen in measures of mobility, self-care, levels of pain and discomfort, and absence of anxiety and depression. But rather than being related just to age, variations in health-related quality of life are also linked to factors such as exercise, nutrition and social engagement.
So being active and eating well could mean a healthier, more independent life for longer.
You’ll feel better in the meantime
Eating healthier and exercising have also been shown to have benefits on your day-to-day wellbeing. Exercise can improve and protect mental health. As a strategy to manage mild to moderate depression, exercise can provide , and can complement medications to improve symptoms further. Similarly, exercise can play a role in treating , obsessive-compulsive disorder, and post-traumatic stress disorder. It can also improve your and even benefit and confidence.
It’s thought exercise does this by reducing your sensitivity to the symptoms of anxiety, building resilience to stressful mood states, positively altering the neurotransmitters in the brain, and disrupting or distracting you from social isolation.
Getting active can also allay general body aches and pains. An recently suggested jogging improves the composition of the cushion-like discs in your spine, reducing wear and tear. Exercise not only fortifies the discs but is also in preventing and treating pain. This is particularly important given 67% of Australians experience pain at least monthly, with inactivity being a major risk factor.
A healthy diet combined with exercise can also , reducing the risk of fractures if you do have a serious injury.
You’ll save more and spend less
There’s , including , that eating healthy food is actually more affordable than an unhealthy diet. And smoking one pack of cigarettes per day, when combined with the health costs that result, is estimated to cost a staggering (A$812,556) to you and society over 50 years.
Type 2 diabetes, often associated with obesity, is estimated to result in A$4,025 per year per person in without medical complications, or in excess of A$9,645 once complications develop. These costs are incurred not only through the need for treatment, but also in job discrimination, higher health insurance costs, lost productivity with sick days and poor physical function.
There’s good evidence, including from Australia, that eating healthy food is actually more affordable than an unhealthy diet.
While no similar analysis exists for Australia, evidence from the US estimates lifetime social and public health costs of obesity at (A$117,332) per person, when combining medical expenditure and reduced productivity.
The to individuals in Australia may be lower due to our universal health system, but the costs from obesity still add up to A$873 million each year. A slice of the Australian budget is spent on the complications of physical inactivity alone, through heart disease, stroke, type 2 diabetes, breast cancer, colon cancer, depression and falls.
This isn’t noted to shame anyone or to recommend reducing care, it’s about realising policy and health inaction comes at a huge economic and social cost.
Your kids will be healthier, and maybe even their kids
Poor diet, smoking, alcohol use and a lack of physical activity can also affect your kids’ health – and maybe even the health of their kids.
Firstly, through role modelling. The kids of parents are more likely to smoke themselves, and likewise with and . These kids are to be obese. Some of these effects could also be from socioeconomic factors.
Second, through a mechanism called , our own health can influence the health of subsequent generations. This results from alterations in the expression of genes and not through changes in the genes themselves.
...Through a mechanism called epigenetics, our own health can influence the health of subsequent generations.
Altered epigenetics from physical inactivity, diet and environmental factors are through generations. They influence the subsequent risk of metabolic diseases such as obesity and diabetes.
Finally, being overweight, a and even could actually reduce your chances of having kids in the first place. In women, being overweight increases the risk of , which causes irregular ovulation and can occasionally render women infertile.
While in men, excess weight contributes to by reducing the quality of semen, as well as increasing the risks of sexual dysfunction.
The bigger picture
Living a healthier lifestyle is about making small, possible, simple and sustainable changes like taking the stairs instead of the lift - not totally rethinking the way you live.
But while there are many compelling reasons to be healthy, personal discipline alone will never solve our chronic disease and obesity epidemics. If neighbourhoods lack safe spaces for kids to run, or fresh food is inaccessible and unaffordable, good intentions will not get you very far. Government policies need to make health easier, even preferred.
In the meantime, look to friends for motivation; your family to share and support a healthy diet; that map and commend the exercise you do; and your GP and important services like for assistance with alcohol reduction and smoking cessation.
