Friday 5 August 2022 10:07 PM DR MICHAEL MOSLEY: Stressed? Don't fret... it can help make you stronger trends now
Are you feeling stressed? Join the club. There’s the cost-of-living crisis, the threat of rising fuel bills and the constant pressures of just keeping our heads above water.
Even before Covid came along, a survey by the Mental Health Foundation found that 75 per cent of Britons reported that they were so stressed over the previous year that they felt they couldn’t cope.
Yet alongside ‘bad’ stress there is also ‘good’ stress, which makes you rise to a challenge and triumph against the odds (I’m thinking of you, Lionesses).
Sometimes a bit of extra stress is just what the doctor ordered. That was the conclusion of a recent study by the University of Georgia in the U.S., which found that being exposed to moderate levels of stress not only makes people more resilient, but also reduces the risk that they’ll develop mental health problems, such as depression and anxiety.

The study, published in the journal Psychiatry Research, involved tests on more than 1,200 young adults who were asked to fill in questionnaires that assessed their stress levels, answering questions such as ‘how often have you found that you could not cope with all the things you had to do?’
They also underwent cognitive tests that measured their memory, ability to switch between tasks and processing speed (how quickly their brains work).
R esearchers concluded, after crunching the numbers, that being exposed to moderate levels of stress enhances people’s cognitive abilities and protects against the risks of developing mental health problems.
It may be that when we’re stressed we learn coping mechanisms that help us overcome future challenges.
There is, of course, a fine line and the researchers point out that while some stress can be good for your brain, continued high stress can be incredibly damaging.
These findings support something I’ve believed for a long time: that when we are exposed to stress, whether it is physical or mental, it can make us stronger.
There is even a name for this: hormesis. This is not just a variant of ‘join the army and it will make a man of you’; hormesis is a way of explaining the health benefits of being continuously challenged.

Take something as simple as exercise. When you run or pump iron, what you are actually doing is damaging your muscles, causing small tears. Your body responds by doing repairs, and that is what makes your muscles stronger.
Eating bitter vegetables is another example. Plants produce compounds called phytochemicals, some of which act as natural pesticides to keep mammals like us from eating them.
They taste bitter because they contain chemicals that are potentially poisonous.Yet many vegetables that are particularly good for us, such as cabbage and broccoli, are so bitter that even adults struggle to love them.
It seems that the toxic phytochemicals are present in such low doses they won’t harm us, but they are strong enough to activate a stress response in our cells, which then switches on genes that make our cells stronger and healthier.
Once you start looking at the world in this way, you realise that many activities we initially find stressful, such as eating bitter vegetables, going for a run and lifting weights, or even practising intermittent fasting — something I am famous for — are hugely beneficial in the long term.
The challenge seems to be part of the benefit. The fact that prolonged starvation is very bad for you does not mean that short periods of intermittent fasting must be a little bit bad for you. Indeed,
