Step 10: Sleep on it

If you’re feeling moody, depressed and irritable, it could just be down to the fact that you’re not getting enough sleep.

It has a huge impact on our physical health, energy and mood.

After just one night’s lost sleep, our immunity-boosting, disease-fighting cells drop by over a quarter, while the stress-inducing hormone cortisol increases by a half.

Aim to get eight hours sleep every 24 hours.

Try going to bed an hour earlier, or having a catnap when you get home from work.
