Being active is one of the key factors to maintaining a healthy lifestyle. People who do regular activity have a lower risk of many chronic diseases, such as heart disease, type 2 diabetes, stroke and some cancers. It can also reduce your risk of stress, depression, dementia and Alzheimer’s disease. As David suggests here, it has done wonders for his health and wellbeing.

David's reflections

Today has been really great. It started off with a run, and I'm really proud of myself because I didn't really want to go. I woke up at 7.30, and partly because I had two drinks last night and was feeling a bit dehydrated, I just didn't really feel like it. But I got out and ran through Finsbury Park. It was one of those wonderful, beautiful morning runs, running through urban parkland. Getting all that air in your lungs, it just starts the day really well.

I started running a couple of years ago; just after we lost the last election in fact. Maybe it was because I had a bit more time, maybe it seemed like a good time to change up a few things. I try to do 10km a week, but I only do that 6–7 months out of the year, and for the rest of the year I'll do something else. Last year I did swimming; I'm not the best swimmer so I really wanted to get better at that.

The great thing about running is that so often you wake up and you think: "I really don't feel like this." And even when you're up and out, that first kilometre is tough. But then once you get to 3km and you're getting to the end of the run, it's really fantastic. I love to run outdoors, being outside, enjoying nature, looking up through the trees, being out among the elements ... I don't think there's a better way to start the day.

And then I had a really wonderful mindfulness session. I might well be a convert to this stuff, in fact, I might even give up being an MP and become a mindfulness coach. I did ten minutes of really deep, intensive breathing, focusing on the soles of my feet, my hands resting on my knees, and at the end I felt like I'd had a holiday. Combined with the run, it meant that today has actually been really special.
