What You'll Learn
Drink water, not coffee
While it may be tempting to reach for a cup of coffee to help you get through a workday after a night of poor sleep, drinking water instead is a better option. Staying well-hydrated is always important, but it is even more vital if you have not gotten enough sleep. Dehydration will make you feel even more tired and rundown than you already do when sleep-deprived. Try to drink at least one glass of water every hour while you are at work. Avoid sugary sports drinks, which may only make you more sleepy.
Caffeine can help you feel more alert, but it can also mess with your sleep that night, leading to even more trouble functioning the next day. The alertness effects of caffeine can stay in your system for up to seven hours, so if you drink coffee late in the day, you may find yourself struggling to fall asleep that night. The average half-life of caffeine is 8 to 10 hours, so if you go to bed at 10:30 pm, you should be fine to drink coffee until about 2 pm. However, if you are very sensitive to caffeine, you may need to cut it off earlier in the day. If you are struggling with sleep, keep track of the time of day you consume caffeine and how you sleep that night. You may find that you need to stop drinking caffeine more than 10 hours before bed to get a good night's rest.
If you are sleep-deprived, you may be able to fall asleep later in the day with no problem. However, the caffeine-nap combination can be dangerous if you are driving or operating heavy machinery. Research suggests you have the same cognitive impairments after being awake for 18 to 20 hours as you would with a blood alcohol level over the legal limit for driving. If you are very sleep-deprived, it is best to avoid driving or doing manual work or dangerous tasks.
Instead of reaching for a caffeinated drink, try getting outside in the sunlight, eating balanced meals, and exercising to boost your energy levels. A 20-minute nap can also help restore your energy levels for several hours.

Get sunlight and exercise
Sunlight and exercise are two effective ways to help you get through a work day on no sleep. Firstly, getting exposure to sunlight in the morning can help you sleep better at night. This is because sunlight helps reset your body's internal "sleep clock". Light is a crucial cue for your body's sleep cycle, helping it to figure out when it's time to go to bed and when it's time to wake up. Sunlight also helps your body make serotonin, a brain chemical that boosts your mood, helps you feel calm and focused, and plays an important role in your overall well-being.
To get your daily dose of sunlight, you could try taking a walk first thing in the morning, or having your breakfast outside. If you don't have access to direct sunlight, you could try light therapy, either by purchasing a light box that emits artificial light, or by opening the windows at home or in your car to let the sunlight in.
When it comes to exercise, it's important to be careful of injury when you're sleep-deprived. Gentle cardio or yoga is safer than an intense HIIT session or strength training. Morning exercise can help you get out in natural light and give you an energy boost for the workday. If you only have time to exercise close to bedtime, opt for something gentle like yoga, so you don't keep yourself awake.
Exercising in the sun can have additional benefits. A study on male university students found that aerobic exercises such as walking or running, combined with sun exposure, positively impacted their sleep quality and sleep-related hormonal responses. However, it's important to be mindful of the amount of sun exposure you get, as excess sunlight can contribute to skin cancer. The World Health Organization (WHO) recommends getting 5 to 15 minutes of sunlight on your arms, hands, and face 2-3 times a week to enjoy the vitamin D-boosting benefits of the sun.

Eat tyrosine-rich foods
Sleep is essential for your health and well-being, and you need 7 to 9 hours of sleep each night to function at your best. However, if you've had a sleepless night and need to get through the workday, eating tyrosine-rich foods can help improve your alertness and mental performance.
Tyrosine is an amino acid that your body naturally produces from another amino acid called phenylalanine. It is also found in many foods and can be taken as a supplement. Tyrosine helps create neurotransmitters, including dopamine, adrenaline, and noradrenaline, which affect your mood, memory, motor skills, and ability to handle stressful situations.
Research has shown that tyrosine can be particularly beneficial for people who are sleep-deprived. In one study, participants who were sleep-deprived due to working overnight experienced improved alertness for about three hours after taking tyrosine. Another study found that tyrosine administration significantly improved performance on psychomotor and vigilance tasks, even after extended wakefulness.
So, what tyrosine-rich foods should you eat to stay awake after a night of no sleep? Here are some options:
- Cheese: Tyrosine was first discovered in cheese, and the word "tyros" means "cheese" in Greek.
- Other dietary proteins: Tyrosine is found in protein-rich foods, so consider eating meat, fish, eggs, or plant-based sources like beans, lentils, and soy products.
- Dairy products: In addition to cheese, other dairy products like milk and yogurt can provide tyrosine.
- Nuts and seeds: These are good sources of tyrosine and can be easily snacked on throughout the day.
- Avocados: Avocados are a tasty, healthy option that contains tyrosine.
By including these tyrosine-rich foods in your meals and snacks, you may find it easier to stay awake and focused during a workday after a sleepless night. However, remember that while tyrosine can help, it's important to prioritize getting enough sleep as much as possible for your overall health and well-being.

Power nap, don't snooze
Power naps are a great way to relieve tiredness and feel more alert. They can be a powerful tool for anyone who experiences sleep deprivation, including people working night shifts, those with jet lag, students, and anyone who has trouble getting enough sleep.
The ideal power nap is between 15 and 30 minutes long. This is long enough to give you the benefits of sleep without leaving you feeling groggy when you wake up. Research at NASA showed that when pilots slept for 26 minutes, alertness improved by 54%, and job performance improved by 34% compared to pilots who didn't nap. Power naps are also shown to eliminate microsleeps, which is the tendency to nod off.
If you're feeling sleep-deprived, it's best to avoid caffeine after 3 pm, as it can stay in your system for up to seven hours and disrupt your sleep later. Instead, opt for a power nap in the early to mid-afternoon, which is unlikely to interfere with your nighttime sleep.
If you can't take a nap, try to get outside and expose yourself to natural sunlight. Morning exercise can also help boost your energy levels for the workday.

Avoid high-maintenance people
Sleep deprivation can cause a lot of negative effects, and drowsiness after sleep deprivation can put you at risk of accidents, slow down your reaction times, impair your physical performance, and hurt your memory. It can also make you irritable and more likely to say or do things you may later regret.
If you have to go to work after a sleepless night, it is best to avoid high-maintenance people or those who require some energy for you to be polite to. You are likely to be less communicative and more surly, and your ability to detect others' non-verbal cues may be impaired. It is also a good idea to avoid high-stakes projects or decisions, especially if you work in a field where your decisions could risk someone's life or health.
Instead, focus on low-stakes, easy tasks, and try to get your toughest tasks done first while you are at your most alert. If you can, reschedule meetings or phone calls, and try to work in short bursts of 25 minutes with 5-minute breaks in between to stay awake.
To keep your energy levels up, snack on protein-rich foods such as string cheese, nuts, eggs, chicken, berries, tofu, milk, and whole grains. Stay hydrated by drinking lots of water, and avoid sugary snacks, sodas, and carbohydrates, which can cause blood sugar spikes and make you feel sleepier.
