If you are contemplating a new year’s health kick, you could be forgiven for feeling a little overwhelmed.
Do yoga, run, lift weights, cut the carbs, or the fat (depending on the particular diet that’s in vogue), ditch the booze, reduce your stress.
It is easy to feel like your life needs to be overhauled in order to be a healthy, happy human being.
But what if you were to make only one change?
We asked experts what single thing they would recommend people should do to improve their health, assuming they are an adult who is otherwise healthy and not a smoker.
Focus on the mind
It is easy to only think about our physical health.
But according to Dr Nadine Sammy, associate lecturer for sport and exercise sciences at the University of Exeter, we should also be focusing on improving our minds by building self-awareness.
You might think of this as something that prevents us from embarrassing ourselves, but, according to Dr Sammy, it is much more than this.
“For instance, what is your motivation to exercise? When are you most – and when are you least – likely to stick to your exercise routine and why?”
There are many ways to do this, she says, including journaling, meditating, practicing mindfulness or simply making time for self-reflection after certain activities or at the end of the day.
“Better understanding ourselves allows us to play to our strengths and build on our weaknesses, thereby spurring us on to be our best self,” she adds.
Adopt a dog
A gym membership, a pilates class, or a morning run – just some of the things that might come to mind when we think of becoming physically more active.
But though going to the gym works for some of us, many will quit after a month or two, says Dr Rhys Thatcher, a reader in exercise physiology at Aberystwyth University.
Instead, he recommends finding ways to routinely incorporate exercise into our daily lives.
There are plenty of ways to do this, from avoiding the lifts at work to parking on the far side of a supermarket car park when you are doing the shopping.
And finally, get enough sleep
It may seem obvious, but we should all aim to get enough sleep (seven to nine hours a night for most healthy adults).
But Dr Buckingham’s top tip is to stop using electronic devices like phones and laptops well before bedtime or at least put on a filter that blocks the blue light in them.
