What You'll Learn
Take a nap before work or during your lunch break
Taking a nap before work or during your lunch break can be an effective way to stay awake and alert during your shift. Research has shown that a 10-minute nap can improve alertness and awakeness throughout your shift, while a 30-minute nap may be ideal, according to 2023 research.
If you're taking a nap before work, try to limit your exposure to light before you sleep. The light and dark around you influence your body's production of melatonin, a hormone that helps you sleep. Sunlight, in particular, can make your body feel more energised when you're trying to wind down, so reducing your exposure to sunlight before bedtime can help you fall asleep more easily. In addition to limiting natural light, you can also try wearing an eye mask to block out any remaining light.
It's also important to limit your screen time before bed, as digital devices like smartphones, computers, and TVs can stimulate your mind and keep you awake. The blue light emitted by these devices can disrupt your sleep, so it's best to avoid them for at least a few hours before you plan to nap.
If you're taking a nap during your lunch break, set multiple loud alarms to ensure you wake up feeling refreshed and ready to tackle the rest of your day. A short 15-minute nap can be enough to boost your mood and improve your performance at work. If you have time, you can also try drinking a heavily caffeinated beverage immediately before your nap, as some people find that this helps them feel more energised.
In addition to napping, there are other strategies you can use to stay awake and alert at work. These include staying hydrated, taking a quick walk, listening to music, and getting some fresh air before your shift. Regular exercise can also help reduce daytime sleepiness, so staying active throughout your shift by taking activity breaks or walking while taking phone calls can help keep you energised.

Get some fresh air and sunlight
If you didn't get enough sleep last night and are feeling drowsy at work, one of the best things you can do is step outside and get some fresh air and sunlight. Here's why this simple act can help you stay awake and improve your alertness throughout the day:
Sunlight is a natural stimulant for your body. It helps regulate your circadian rhythm, which is your internal clock that governs sleep and wake cycles. When you're exposed to sunlight, especially in the morning, it signals to your body that it's time to wake up and be alert. The bright light suppresses the production of melatonin, the hormone that makes you feel sleepy, and boosts your energy levels. Even on cloudy days, the effect of natural light can be beneficial, so don't let a little cloud cover deter you.
Fresh air is equally important. Taking a few deep breaths of fresh, outdoor air can help increase your oxygen levels, which in turn stimulates your brain and body. If you've been cooped up inside an office or a stuffy room, the change in environment and air quality can make a significant difference in how alert and refreshed you feel. The act of stepping outside and taking a short walk can help clear your head, improve your focus, and boost your overall mood.
To maximize the benefits, try to spend at least 15–30 minutes outside. Take a short walk during your break, eat lunch at a nearby park, or simply stand outside and soak in the sunlight. If you can't step outside, try to sit near a window where natural light enters the room. You can also open the window to let in some fresh air and create a more stimulating environment.
Exposing yourself to sunlight during the day can also help improve your sleep quality at night. Natural light exposure during the day improves your ability to fall asleep more easily and wake up feeling more refreshed. So, getting some sunlight during your workday can have both immediate and long-term benefits for your sleep and overall well-being.
Remember, while getting fresh air and sunlight can help improve alertness, it's also important to prioritize getting a good night's sleep as often as possible. If you consistently find yourself struggling to stay awake during the day, evaluate your sleep habits and make changes to improve your sleep hygiene.

Stay hydrated and avoid caffeine after 3 or 4 pm
Staying hydrated is a great way to stay awake at work without caffeine. While coffee or tea can jumpstart your day, too much can dehydrate you or make you restless. Drinking water throughout your shift is a healthier and more effective way to stay alert. Dehydration can make it harder to concentrate, so sipping on water can help you stay focused.
If you're feeling tired, it's best to avoid caffeine after 3 or 4 pm. The half-life of caffeine is between four and six hours, which means it can take that long for just half of the caffeine you consumed to leave your body. Drinking caffeine in the late afternoon or early evening can affect your sleep quality. Caffeine blocks the adenosine receptors in your brain, preventing the activation of sleep-promoting pathways. This is why caffeine keeps you awake and alert.
If you're struggling to stay awake at work, try taking a quick walk or getting some fresh air. Moving your body and getting your blood flowing can help you feel more alert. You can also try listening to music to wake up your senses and take your mind off feeling tired. Keeping your workspace cool can also help, as a warm room can make you feel sleepier.
To avoid feeling sleepy at work, it's important to get quality sleep the night before. The light and dark around you influence your body's production of melatonin, the hormone that helps you sleep. Reducing your exposure to light before bed by limiting screen time and keeping your workspace well-lit during the day can help regulate your sleep-wake cycle.

Eat small, healthy meals throughout the day
Eating small, healthy meals throughout the day is a great way to keep yourself awake at work. Eating a large meal can make you feel sleepy, so opt for smaller portions instead. Eating healthy snacks during the day can help keep your blood sugar and attention steady.
To keep your energy levels up, it is important to eat a balanced breakfast. A good breakfast replenishes your glycogen stores, making it easier to stay focused and perform at your peak. A balanced breakfast might include eggs, avocado, oatmeal, or other foods rich in complex carbohydrates.
It is also important to avoid refined carbs and sugar in the morning. Sugar causes blood glucose spikes followed by crashes, so limit your intake and make smart food choices for lasting energy. Instead of a cookie or a chocolate bar, try almonds, pumpkin seeds, chia pudding, or other snacks rich in protein or healthy fats. These snacks can boost your energy throughout the day.
In addition to healthy snacks, drinking water can also help keep you awake. According to a study by Tufts University, dehydration can cause fatigue and confusion and leave you feeling sluggish. Drink water throughout the day to stay hydrated and improve your ability to concentrate.

Take regular breaks and move your body
Taking regular breaks and moving your body is a great way to stay awake at work. Sitting or standing still for too long can make you feel tired, so it's important to get up and move around. You can try walking around your office or workplace, or if you're unable to leave your desk, do some basic stretching exercises. Try stretching your arms over your head, rolling your neck side to side, or doing some torso twists to loosen up tight muscles and keep your body energised.
If you can, get some fresh air during your break. A walk in the morning sun can be especially effective in increasing your alertness. Sunlight can help manipulate your internal clock into "daytime work mode", so if you work during the day, keep your window shades open to let in the sunlight. If you're working at night, turn on the lights. Research suggests that short-wavelength dominant light (like LED lights) and higher-intensity white light (like HID lamps) may be most effective for alertness.
If you're unable to get up from your desk, there are still some things you can do to stay awake. Try lifting your feet off the floor to engage your leg muscles, or do a quick squat to get the blood pumping. You can also try holding your breath for a few seconds to wake up your brain.
In addition to moving your body, staying hydrated is important to staying awake. Drinking water throughout your shift will help keep you alert, while dehydration can make it harder to concentrate.
