Summarize this article in one sentence.
Some fresh air can help to keep you awake and alert. If you tend to stay inside much of the day, take a few breaks and head outside. Getting some sunlight (especially in the morning) can help regulate your waking and sleeping cycles so that you’re fully awake during the day and can sleep well at night.  Take a walk during your lunch break or ask to meet with people outside. For example, if you have a dog, go for a walk each morning so you can maximize your sun exposure. Engaging in social activities can help to keep you alert and involved. Find a friend to talk to. This might also be a good time to make any necessary phone calls.  Avoid using instant messaging to communicate; it’s best to speak in-person or over the phone to stay awake. Talk to another student or co-worker throughout your day. Schedule regular meetings so that you can be continuously engaged. Avoid reaching for the sugary snacks and grab something that will give you long-lasting energy. For example, try eating a handful of nuts or a bowl of fresh fruit. Spread some nut butter on a whole grain cracker or eat a yogurt. When you get a craving for a snack, get in the habit of fueling yourself for long-term energy to help avoid any lows that might make you drowsy or tired. If you’re struggling to stay awake, get up and take a 10-minute walk. Moving around can increase blood flow and provide oxygen throughout your body. Simple movement can help increase energy for up to 2 hours.  If you can’t take a walk, do some stretches or movements to wake up your body. Try some jumping jacks or burpees. If possible, use the gym or attend a yoga class in the morning or during lunchtime. Adding a supplement to your day can help to increase energy and keep you awake. For example, B vitamins are known to help increase energy, especially if your diet is low in B vitamins. However, beware of supplements that promise energy without any research or support.  Speak to your physician before starting any new supplements or medications. Be cautious of using stimulants like caffeine as they can increase feelings of anxiety.  Caffeine may also affect the quality of your sleep.

Summary:
Get outside to regulate your circadian rhythm. Talk to someone as a way to stay engaged. Grab a healthy snack when you’re hungry and sleepy. Move your body to increase your blood flow for energy. Use a supplement for energy.
