Ever feel like you're pulled in so many different directions—between work, family and other obligations—that simply getting to your "to-do" list is on your to-do list? The focus you demand of your brain requires a lot of energy—almost 20% of your body's total energy, to be exact. No wonder so many of us feel frazzled! The good news is, you can support optimal mental focus with a healthy lifestyle, and some nutrients targeted to encourage cognitive performance.

1. Foods for focus

   Breakfast is the most important meal of the day for a reason. Fuel your body and your brain first thing in the morning to improve short-term memory and attention. Make sure to fill your plate with whole-grains and fresh fruits—bonus points if you can add in a lean protein. For evening meals, try incorporating healthy fats, like salmon, which is rich in brain-boosting omega-3 fatty acids.

2. Sleep to stay sharp

   Like your smart phone, your brain needs to be properly recharged every night to stay smart! Getting eight hours of uninterrupted sleep is optimal; of course, for some, that may be easier said than done. If you are having trouble falling asleep, try supporting your body's internal clock with a nutrient like melatonin. Also cut out caffeine before bedtime and keep your eyes off blue light-emitting electronic devices for at least two hours before your head hits the pillow.

3. Play brain games

   Keep your memory limber and your focus laser-sharp by exercising your brain. Puzzles are a great way to improve short-term memory by engaging your brain with colors and shapes. If you're more of a wordsmith, try a crossword puzzle and increase the difficulty over time, so you can continue to challenge your cognitive powers.
