What your morning routine should look like, according to science

Most of our daily routines are so ingrained that we rarely think of changing them. But many of our morning habits aren't helping us to be the most productive, joyful versions of ourselves.

A spate of research on everything from our breakfast to our workout routines is helping to illuminate a handful of opportunities to change things up for the better.

Read on to learn when you should time your coffee to get the most of your buzz, what kinds of workouts to prioritize in the morning, and even whether popping that daily multivitamin is worth the money.

Skip the shower.

If you showered yesterday, you should probably skip it today. A growing body of evidence suggests that showering too much canmess with your skinanddry out your hair, since it can wash away many of the naturally occurring but beneficial bacteria and oil that keep skin and hair healthy.

"It's paradoxical, but people who wash their hair a lot to get rid of oil are drying out their scalp and producing more oil,"Lynne Goldberg,a dermatologist and the director of Boston Medical Center's hair clinic, told Business Insider.

When it comes to setting up your own regimen, consider two things: the average dryness of your skin and scalp, and the texture of your hair. If they are neither very oily nor very dry, you likely only need to batheonce or twice a week. If your hair is curly and thick, you may need to wash it even less frequently, since coarse hair slows down the spread of oil from your roots through the length of your hair.

Brew your coffee — but don't drink it yet.

Many things naturally happen to our bodies when we wake up. We start pumping out the hormone cortisol, a sort of natural caffeine. Most people's cortisol levels peak sometime between 8:00 and 9:00 in the morning.

Instead of hopping aboard this wakefulness train, however, coffee consumed at this time may actually blunt cortisol's natural effects,according to Stephen Miller, a Ph.D. candidate at the Uniformed Services University of the Health Sciences in Bethesda, Maryland. Instead of caffeinating during this window, Miller recommends holding off for an hour after you awaken.

Hit the track.

Research suggests thatan early-morning workout on an empty stomachhelps speed weight loss and boost energy levels by priming the body for an all-day fat burn. Exercising first thing in the morning maypush the body to tap into its fat reserves for fuelinstead of simply "burning off" the most recent snack or meal.

Plus, working out early could mean you get more sunlight, which is key to properly setting your body's internal circadian rhythm. In one study, people who basked in bright sunlight within two hours after waking werethinner and better able to manage their weightthan those who didn't get any natural light, regardless of what they ate throughout the day. A morning walk or run outside can also help fight the winter blues during dark, cold days.

Get your heart pumping.

Any kind of exercise is a healthy way to start the day, but the type that offers the most benefits for your body and brain is aerobic exercise, or cardio.

"Aerobic exercise is the key for your head, just as it is for your heart," write the authors of anarticle in a Harvard Medical School blogcalled Mind and Mood.

Cardio is the closest thing to a miracle drug that we have. Studies suggest that running or swimming helps to lift your mood and clear the mind. It may even help protect from some of the cognitive decline that occurs with age. It also strengthens the heart and lungs and helps tone up muscles. So get moving — preferablyfor at least 45 minutes at a time.

Fuel up.

If you normally eat breakfast, there are three key ingredients it should have: protein, fiber, and healthy fats. Most US breakfasts are lacking in all three. Instead, they're full ofrefined carbs, a type of unhealthy carbohydrate that gets rapidly turned into sugar in our bodies. Pancakes, bagels, muffins, and even cereal allfall into this category. Add juice to the mix and you've got a big dessert.

Instead, try a couple of eggs with a few avocado slices, or someGreek yogurt (the plain kind, since the flavored varieties can be high in sugar) with fruit and nuts. Both of these options will fill you up, help smooth out your digestion, and power up your muscles.

Or skip breakfast entirely.

If you're looking to lose weight and other diets have failed you, you might want to try aneating plan known as intermittent fasting— after checking in with your doctor, of course. There are several versions of the diet, but one of the most popular involvesfasting for 16 hoursand eating for eight. Most people opt for an eating window of 12 p.m. to 8 p.m , meaning you essentially skip breakfast but eat whatever you want within the eight-hour "feeding" window.

Large studies have found intermittent fasting to be just asreliable for weight loss as traditional diets. And a few studies in animals suggest it could have other benefits, such asreducing the risk for certain cancers and evenprolonging life— but those studies need to be repeated in humans.

Ditch the multivitamin.

The ingredients you're looking to get from a multivitamin are better processed by your body when they come from real food. If you're not eating right, taking a vitamin isn't going to do you much good anyway. For these and other reasons,experts are suggesting that people stop taking many vitamins and supplements, since they're part of alargely unregulated industry.
