She runs a fashion empire, constantly jets between continents and has her hands full raising four kids – yet Victoria Beckham always manages to look the part and appear full of energy.

So what is the trick, we hear you wonder. Well, according to Harper's, instead of taking a long, hot shower when you first get up in the morning, try doing this instead: Blast yourself with cold water for 30 seconds, then with hot water for 30 seconds, and then for a final 30 seconds with freezing water. (Note: This routine should be at the end of your shower, so wash yourself as usual first in hot water, then end your shower with the cold-hot-cold routine.)

This might seem terribly uncomfortable, but experts swear it really works, and that the cold water will not just give you a total wake-up call and boost your energy first thing, but will also help increase blood flow, open up the capillaries, help firm your skin, burn fat and even improve your immune system. Daunted by the idea of a freezing shower first thing? Well, we tried it and, honestly, it is not as bad as you think. We'll get back to you on the firmer thighs when it happens, but as for waking us up, this trick works, for sure.
