Feeling tired all the time? Follow these science-backed tips to restore your vitality...

Enjoy yourself more!

Best-selling author and executive coach Peter Bregman suggests identifying what you spend the most energy on, compared with what you would like to spend it on. ‘Let go of niggling worries, leave pointless conversations and stop replying to every single email to free yourself up to spend more energy on things that bring you joy,’ he recommends.

The mineral magnesium helps turn the food we eat into energy and we need between 270mg (women) and 300mg (men) a day, says the NHS. So make sure you’re eating at least four portions of magnesium-rich foods daily, such as leafy green veg, pumpkin seeds, nuts, bananas and avocados.
