What You'll Learn
Take a power nap before work
Taking a power nap before work is a great way to boost your alertness and productivity for the day ahead. Power naps are short in duration, typically lasting between 10 and 30 minutes, and are designed to give you a quick energy boost without leaving you feeling groggy.
The key to a successful power nap is timing. Aim to nap for only 15 to 20 minutes, as this will provide a quick recharge without entering the deeper stages of sleep, which can leave you feeling sluggish upon waking. Set multiple alarms to ensure you don't oversleep.
To prepare for your power nap, find a quiet, comfortable, and isolated place to rest. This could be in your parked car, on public transport during your commute, or even in your office if there's a quiet room available. Ditch your phone and, if you wish, play some relaxing music to help you unwind and fall asleep faster.
Before your nap, consume something with protein and calcium, like a glass of milk, to curb any hunger pangs. Avoid caffeine, fat, carbohydrates, or sugar, as these can keep you awake.
If you're feeling adventurous, try drinking a caffeinated beverage immediately before your power nap. This way, you'll wake up not only refreshed from the nap but also energized from the caffeine, which would have kicked in during your slumber.
By incorporating power naps into your daily routine, you'll be able to train your body to fall asleep quickly and enjoy the benefits of improved focus and alertness throughout your workday, even after a sleepless night.

Get sunlight and fresh air
Sunlight and fresh air can be powerful tools to help you stay awake at work, especially if you've had a poor night's sleep. Sunlight is a natural way to energise your body and reset your internal clock. Your body's circadian rhythms, or internal clock, are based on the lightness or darkness of your environment. When your brain perceives darkness, it releases melatonin, the hormone that makes you feel drowsy and prepares your body for sleep. Sunlight has the opposite effect, making your body feel more energised.
If you work during the day, keep the window shades open to let in natural light. If you're working when it's dark or dim, turn on the lights to help keep you awake and alert. Research suggests that short-wavelength dominant light (like LED lights) and higher-intensity white light (like HID lamps) may be most effective for alertness.
In addition to sunlight, spending time outdoors in the fresh air can help wake you up. Take a walk during your break to increase your blood flow and bring more oxygen-rich blood to your muscles. A change of scenery can also reduce fatigue, inspire new ideas, and spark creativity. If you can't go outside, simply cracking a window to let in a refreshing breeze can help keep your blood flowing and your energy levels up.
If you're feeling particularly tired, try splashing your face with cold water. This will draw your circulation upward toward your head, temporarily renewing your energy and making you feel more awake.

Drink water, not caffeine
Drinking water is a great way to stay awake at work after a night of poor sleep. Caffeine may be the go-to for many people, but it is not the only option and can be detrimental to your health. Water is a healthier alternative to caffeine and is more effective in keeping you alert throughout your shift. Dehydration can make it difficult to concentrate on your work, so drinking water will help you stay focused.
Drinking water throughout your shift will keep you alert and has the added benefit of not interfering with your sleep after work, unlike caffeine. Consuming caffeine early in your shift can boost your alertness, but only if it is limited to the start of your shift. Caffeine too late in the day can negatively impact your ability to sleep, so it is best avoided if you are already struggling with sleep.
Water is a healthier option than caffeine, which can lead to dehydration and restlessness. Drinking water will help your circulatory system and get your blood flowing, which is important when you are feeling tired. If you have a headache from too much caffeine, water can help relieve it.
To ensure you are staying properly hydrated, aim to drink an ounce of water for every pound of body weight. This will ensure you are getting enough water to keep you alert and energized throughout your shift.
In addition to drinking water, there are other ways to stay awake at work without caffeine. Taking a walk can help bring blood flow to your muscles and wake you up, especially if you are able to get some sunlight. Sunlight will help regulate your sleep-wake cycle, so even a short walk outside can be beneficial.

Eat small portions throughout the day
Eating small portions throughout the day can help you stay awake at work when you haven't slept. Large meals can make you feel sleepy, so it's best to stick to smaller meals and healthy snacks. Eating too much sugar can cause blood sugar spikes, which will result in a surge of high energy followed by a slump of low energy, leaving you feeling tired.
Healthy snacks such as fruits, nuts, and seeds can help keep your blood sugar and attention steady throughout the day. Eating small portions regularly can also help maintain your blood sugar levels and prevent dips in energy.
In addition to eating small portions, staying hydrated is crucial. Drinking plenty of water throughout your shift will keep you alert and help your circulatory system. Dehydration can make it harder to concentrate, so carrying a water bottle with you and sipping on it throughout the day is a good idea.
If you're feeling particularly tired, a drink with caffeine can provide a temporary energy boost. However, caffeine may cause an energy crash later, so it's best to opt for drinks with less caffeine, such as green or black tea, which have a gentler stimulating effect.
While eating small portions throughout the day can help, combining it with other strategies will be even more effective in keeping you awake. Taking active breaks, getting some fresh air, and moving your body before and during work can boost your alertness.

Talk to a friend or colleague
If you're feeling sleepy at work, one of the best ways to stay awake is to talk to a friend or colleague. An engaging conversation leaves little room to feel tired, and people who regularly converse with others tend to be more alert.
Choose conversations over emails whenever possible, as this can also help improve workplace monotony. If you're working remotely or don't have access to a colleague, try giving a friend a call.
If you're sitting in on a meeting or on a call and can't move around, try to keep your focus by engaging your leg muscles. Simply lifting your feet off the floor will help you stay awake, and people in the room are unlikely to notice.
If you're able to move around, take a walk to help bring blood flow to your muscles and wake them up. A change of scenery is also likely to reduce fatigue by inspiring new ideas and sparking creativity.
If you're unable to get up and move around, try some basic stretches at your desk or workstation.
