It’s been the month of juice diets, 5:2 eating and new exercise regimes. If you follow my blog, you’ll know that I think Mindlessness, as opposed to Mindfulness, is the healthiest way forward, and hence, we must move more! So, as I drink in the fitness decisions taken by friends and loved-ones around me, I start to think: when is the best time to exercise?
Inspired by a recent talk by Richard Jolly, Adjunct Professor of Organisational Behaviour at London Business School on happiness at work, I’d like to explore what role exercise plays in our happiness. Stay tuned to become happier!
“95% of senior executives I work with tell me they are ‘Hurry Sick’ – addicted to email and disillusioned with inefficient meetings.
“Realising that they have achieved everything that would make them happy, but finding they were unhappier than they had ever been is at the heart of the mid-life crisis. This pattern is not what is going to inspire the next generation of employees to join and stay loyal to an organisation.”
Stress the body and de-stress the mind
Stress, over time, can:
- Cause key connections between nerve cells in your brain not to function well
- Impair your memory and the ability to take in new information
- Increase your risk of suffering from depression and anxiety.
So, how can exercise-stress trigger happiness?
- As your heart-rate goes up, say hello to feel-good serotonin, dopamine and norepinephrine – these are good folks to have around
- A substance to protect your brain from emotional disorders and repair damage that stress and depression cause − Brain-derived neurotrophic factor (BDNF) – appears
- Now for the good bit: opiate-like endorphins kick in, leading to a happy-sigh state of well-being.
Did you know that 20 minutes of exercise can produce mood enhancers that last as long as 12 hours? Cambridge University studied of 334,000 people and Ulf Ekelund, who led the study, said:
“This is a simple message: just a small amount of physical activity each day could have substantial health benefits for people who are physically inactive.
“Although we found just 20 minutes would make a difference, we should really be looking to do more than this – physical activity has many proven health benefits and should be an important part of our daily life.”
When to exercise?
So, hopefully you’re planning to work-out, but when should you do it?
Your body’s circadian rhythm determines whether you’re a lark or an owl, and I’m afraid there’s not much you can do to change it! (I’m a lark, and can be found quietly flagging between 16.30 and 18.30.)
Circadian rhythm is affected by the 24-hour pattern of the earth’s rotation. These rhythms influence body functions, like: blood pressure; body temperature; hormone levels; and heart rate, all of which play a role in your body’s readiness for exercise.
I may be bias, but experts have said that morning is your best time to exercise.
“Research suggests in terms of performing a consistent exercise habit, individuals who exercise in the morning tend to do better,” says Cedric Bryant, PhD, chief science officer with the American Council on Exercise in San Diego.
“The thinking is that they get their exercise in before other time pressures interfere,” Bryant says. “I usually exercise at 6 a.m., because no matter how well-intentioned I am, if I don’t exercise in the morning, other things will squeeze it out.”
If you stay sedentary your body can become more sensitive to stress, so even minor triggers – you know, the washing machine breaking; organising a Hen Party; or having a crap date − leaves you mentally exhausted. Look, I’m not the ‘fit and fun police’, but if you can squeeze in 20 minutes exercise a day and you’re physically able to, why not try it and see if you land sunny side up?
