    If you’re working on something that requires hours of work and commitment, a break can provide a much-needed vacation for your brain. Take a 10-minute walk around the block, meditate at your desk for 5 minutes, or do a few simple stretches. When you return, you'll feel refreshed and ready to tackle your work. [1]
    • Go outside for a few minutes. A change of scenery can work wonders in restoring your alertness.
    • Take a snack break if you’re drained of energy and your stomach is growling. Choose something with healthy nutrients, like walnuts, to give your brain a boost.

    You need at least 7 hours of sleep each night to rest your mind and body. Pick a bedtime and start winding down about an hour before that. Take a hot shower, read a book, or drink some hot tea. [2] Getting plenty of sleep will have you waking up feeling alert and ready to take on the day each morning! [3]
    • If you've ever woken up feeling cranky after staying up late, it could be because your rapid eye movement (REM) sleep cycle was interrupted. During this cycle, your mind sorts information and stores memories. Disrupting that can leave you feeling distracted and impatient.

Exercise regularly.

    Consistent exercise increases the blood flow to your brain, which provides the brain with more energy and oxygen. This enhances your cognitive functions, including memory, concentration, and mental alertness. [4]
    • Aim for 30 minutes of moderate-intensity exercise, like jogging or bike riding, five times a week. [5]

    If you have to sit for extended periods during the day, get up and stretch every 30 minutes to get your blood flowing again. [6] You can also try using a standing desk at work if taking a movement break every 30 minutes doesn't work for your schedule.
    • Get creative to add more movement to your life. Stand up while watching TV at home or go on a walk with your coworkers for a meeting instead of staying in the office. [7]

    Fill up your lungs with air, letting your chest and belly rise, and allow your abdomen to fully expand. Then, slowly exhale through your mouth. Keep taking deep breaths in and out until you feel recharged. [8]
    • For best results, practice deep breathing exercises for 10-20 minutes every day. [9]

    Ever listen to an old song and feel like you’ve been transported right back to middle school? That’s no accident! According to Johns Hopkins Medicine, music improves memory function and engages your brain. Next time you’re feeling drained and unable to focus, turn on the radio and listen to some tunes. [10]

    In addition to the numerous and necessary health benefits of drinking water, it improves your brain function and keeps you feeling energized. [11] Dehydration leaves you feeling tired and reduces your energy level. Take a water bottle everywhere you go and take a sip (or two) every time you’re thirsty to stay focused. [12]
    • Use a reusable water bottle if you struggle to drink enough water throughout the day.

    This helps your body utilize all the nutrients in your food for fuel! [13] Try eating 6 small meals a day instead of 3 big meals. Ever eaten a giant meal and felt like you had to lie down the rest of the day? It wasn't in your head! Overeating can leave you feeling lethargic and distracted and contributes to stress in the long term. [14]
    • Avoid eating close to bedtime so that you don't disrupt your sleep.

    More research is needed, but studies show that including Omega-3 fatty acids in your diet improves brain health and even decreases your risk of developing Alzheimer’s disease and dementia. [15]
    • Eat baked fish, like salmon and trout, to incorporate this healthy vitamin in your diet.
    • You can also try nuts and seeds like chia seeds, flaxseeds, and walnuts to get a healthy dose of Omega-3s. [16]

    Though it’s great to have so much information at your fingertips, it can really feel like too much sometimes! Try limiting yourself to 30 minutes a day and see if you start feeling more alert in your daily life. [17]
    • Consider a full-on break if certain apps are causing you a lot of stress! 30 days of no Instagram may really help you focus on what’s important or at least help you develop a healthier relationship with the site. [18]
    • A study published by the American Psychological Association shows that spending too much time on social media, especially during social events like dinner with friends or family, causes you to enjoy the moment less and struggle to remain present. [19]

    Meditation helps you regain your focus by returning to the present moment. Both of these help you take back control of your thoughts and remain alert! To start, try sitting in a comfortable space for 5 minutes. Close your eyes and take deep breaths. Focus on only your breaths, letting your thoughts come and go without attachment. [20]
    • Try 5 minutes of meditation and move on to 10-20 as you get more comfortable.

    Coffee and energy drinks can really help boost your energy, but drinking too much can disrupt your sleep. Limit yourself to one cup of coffee in the morning, and don't drink any caffeinated beverages after 2:00 pm. [23] Switch to tea in the afternoon if you need a refreshing, hot beverage. [24]
    • Caffeine can keep you up into the wee hours of the night if you drink it too late. If you're especially sensitive to caffeine, don't have any after 12:00 pm.
    • Due to the effects of caffeine withdrawal (fatigue and irritability), consider cutting back gradually. If you have three cups a day, for example, limit yourself to one cup in the morning instead. [25]

    Alcohol is a central nervous system depressant, and studies show it can make you sleepy with consistent use. To increase alertness, limit the number of alcoholic drinks you consume. When you're out with friends, for example, stick to 1-2 drinks.
    • Recreational drugs and cigarettes can also affect your ability to stay alert. Though they may help you focus in the short term, long-term use can leave you feeling lethargic and distracted. [26]

    According to the National Institute of Health, smelling oils can stimulate the smell receptors in your nose. This can positively affect your mood, as the smell sends a chemical message to your brain’s limbic system. [27] A study published in the International Journal of Neuroscience found that smelling peppermint can improve your memory and cognitive function. [28] For increased alertness, smell peppermint and citrus scents like lemon. [29]
    • Essential oils are potent and can cause skin reactions to those with sensitive skin. It’s best to smell them rather than applying them to the skin directly.
    • Use a diffuser to disperse the essential oil into the air.
    • Although some studies support the use of aromatherapy for alertness, more research needs to be done to determine its efficacy and limitations. [30]

    If you're really just struggling with work, it may not necessarily be a problem with alertness, but motivation. I'd recommend trying to externalize your motivation. So, if you want to write a novel, you'd join a writing class. If you wanted to be more organized, you might put alarms on your phone to remind you to stick to your schedule. If you can find a way to do something like this at work, you might have a much easier time getting things done.

    It may be very simple, but have you tried getting more sleep? It sounds like you may just not be getting enough sleep. Beyond that, you might consider a morning cup of coffee.

      About This Article

      Article Summary X

      To increase alertness, start by getting at least 7 hours of sleep a night if you’re an adult or 8 hours if you’re a teenager, since adequate sleep is critical to alertness. Then, eat foods that are high in vitamin B12, like nuts and leafy green vegetables, which are known to increase mental sharpness. Additionally, drink at least 8 glasses of water a day, since water helps optimize brain function. You can also jump-start your brain by sniffing an essential oil, such as sage or peppermint oil, which can stimulate your senses and immediately boost your alertness. For tips from our Mental Health reviewer on how to use background music or an impromptu dance party to increase your alertness, read on!
