Cocaine and caffeine can certainly put a jump in your step.

But their energizing effects are spiky and short-lived. Caffeine increases alertness by blocking the effects of adenosine, a brain chemical that makes you feel tired while triggering the release of adrenaline. Cocaine immediately raises body temperature, blood pressure and heart rate. Along with fleeting euphoria as dopamine blasts into synapses.

Thankfully there’s a better, more natural and longer-lasting way to feel energized without having to call your dealer or call into your barista.

Consider that when you’re alert, your eyelids are open because neurons in your brain are making it easier to keep them open.

When you’re tired, your eyelids close and your chin moves down. When you’re wide awake the opposite happens. Your eyelids open all the way and your chin is up.

Your body’s system of alertness is linked to the position of your eye. When you look up and your eyelids are up, the melanopsin cells in the bottom of your retinas create a wakefulness signal for your brain.

If you’re feeling tired, look up to the ceiling with your chin up and eyes raised. Imagine you’re looking up at the sky on a sunny day. Take a few deep breaths. (Better yet, go outside and look up at the sky as you breathe deep.)

Looking down at your phone or laptop screen all day makes it harder to stay alert and focused. Your chin is down, your eyes are down, your energy levels are naturally down.

Position your computer and device screens so you’re looking up.

And feel your energy rise.
