Sleep deprivation is a common issue, with many people getting less than the recommended 7–8 hours of sleep per night. This can have a significant impact on cognitive performance, including attention span, concentration, and reaction time. While it's important to prioritize sleep, there are also strategies to help you focus when you haven't gotten enough rest. This includes taking short naps, consuming caffeine in moderation, exercising, and eliminating distractions. Additionally, maintaining a consistent sleep schedule, creating a conducive sleep environment, and addressing any underlying conditions or sleep disorders are crucial for improving sleep quality in the long term.

What You'll Learn
Take a nap to improve alertness and focus
Napping is a great way to improve alertness and focus, especially if you have not had a full night's rest. A short nap during the day can boost your energy and improve your overall well-being.
The ideal nap length for adults is about 20 minutes, with 30 minutes being the longest recommended duration. This is because a power nap allows your body and mind to rest without entering the deeper stages of sleep. Once you enter deep sleep, typically about 30 minutes after falling asleep, you are likely to experience "sleep inertia" upon waking, which is the groggy feeling you may get that can last 30 to 60 minutes. A 20-minute nap has been shown to improve alertness and focus, with benefits emerging 35 minutes after napping and lasting up to 125 minutes.
If you nap for longer than 30 minutes, you may experience impaired alertness and performance. Longer naps can also interfere with your nighttime sleep, causing insomnia. However, in some cases, a longer nap of around 90 minutes may be beneficial, as it allows the body to cycle through the stages of sleep and can be especially helpful for shift workers who need to avoid fatigue.
The best time to take a nap is between 1 and 3 pm, as this is the natural slump time for humans. If you nap earlier, your body may not be ready for more sleep, and if you nap later, it can disrupt your nighttime sleep.

Avoid sugar and caffeine crashes by eating whole grains, vegetables and good fats
To avoid sugar and caffeine crashes, it is important to understand what causes them. A caffeine crash can be caused by a lack of sleep, consuming caffeine too close to bedtime, or consuming too much caffeine. Caffeine stimulates your nervous system, enhancing focus and cognition while delaying fatigue. However, when the effects wear off, you may experience a crash, with symptoms like extreme tiredness, an inability to concentrate, irritability, or headaches.
Sugar crashes, on the other hand, are caused by a sudden drop in blood glucose levels. This happens when the body has more sugar than it is used to, leading to rapid insulin production and a subsequent decrease in blood glucose. To avoid sugar crashes, it is crucial to maintain balanced blood glucose levels. This can be achieved by incorporating whole grains, vegetables, and good fats into your diet.
Whole grains are complex carbohydrates that take longer to digest compared to refined grains. They provide a steady release of glucose into the bloodstream, preventing sudden spikes and crashes in energy levels. Examples of whole grains include brown rice, bulgur wheat, and whole-wheat pasta. These are excellent sources of fiber, which helps slow the absorption of glucose, giving you better blood sugar control throughout the day.
Vegetables are also an important part of a balanced diet aimed at avoiding sugar crashes. They are typically low in simple sugars and rich in complex carbohydrates, which provide a more sustained release of energy. Additionally, vegetables contain essential vitamins, minerals, and fiber, which contribute to overall health and help regulate blood sugar levels.
Good fats, such as those found in nuts, seeds, avocados, and healthy oils, play a crucial role in stabilizing blood sugar levels. Consuming healthy fats along with meals or snacks that contain simple sugars can help slow the absorption of glucose, preventing a rapid spike followed by a crash.
In summary, to avoid sugar and caffeine crashes, prioritize getting adequate sleep and incorporate whole grains, vegetables, and good fats into your diet. This combination will help stabilize your blood sugar levels, providing a consistent source of energy throughout the day.

Exercise, but keep it light or moderate
Exercise is a great way to stay alert and focused, even when you're feeling sleep-deprived. However, it's important to keep it light or moderate, especially if you're already exhausted.
When you're tired, a vigorous workout may be the last thing on your mind, and that's completely understandable. But a gentle walk can do wonders for your energy levels. Walking gets your blood flowing, and if you walk outside, you'll benefit from the natural light and fresh air, which can help wake you up and improve your focus. Plus, movement stimulates alertness in the brain, so you'll feel more energized.
If you're able to, try taking a short walk break during your day. It can be as simple as walking around your building or taking a quick stroll during your lunch break. Even a few minutes of walking can help you feel more energized and refreshed.
Moderate aerobic exercise is a great option, too, and you don't need to train for a marathon to improve your sleep and focus. Just 30 minutes of moderate activity, like a brisk walk, swimming, or cycling, can make a difference. This type of exercise increases the amount of slow-wave sleep you get, which is the deep, rejuvenating sleep your brain and body need. Plus, it can help stabilize your mood and create a natural transition to sleep, making it easier to fall asleep and improve your overall sleep quality.
However, it's important to listen to your body and find the right time to exercise. For some people, working out too late in the day can interfere with their sleep. Aim to exercise at least 1-2 hours before bedtime to give your brain time to wind down and endorphin levels to wash out.
Exercising regularly is a great way to improve your sleep and focus, but remember to keep it light or moderate, especially when you're feeling exhausted. By incorporating gentle walks and moderate aerobic exercise into your routine, you'll be well on your way to improved alertness and focus.

Take breaks and go outside for natural cues to promote wakefulness
Taking breaks and going outside for natural cues can be an effective way to promote wakefulness and improve focus when you haven't had enough sleep.
Firstly, taking breaks throughout the day can help to improve your focus and alertness. This could mean taking a short walk outside, which provides the dual benefit of movement and sunlight. Even a brief step outside for some fresh air can revive your senses. If you are unable to go outside, you can still take a break by doing some light stretching at your desk or taking a walk around the building.
When taking a break, you can also try some basic desk exercises to keep the blood flowing and your body energised. For example, you can try stretching your arms over your head, rolling your neck from side to side, or doing some torso twists. These simple movements can help loosen tight muscles and keep you energised.
Exposing yourself to natural sunlight is an effective way to promote wakefulness. Our circadian rhythms, which regulate our sleep-wake cycle, are influenced by daylight. Aim to spend at least 30 minutes a day outside in natural sunlight. If you have insomnia, sleep experts recommend an hour of morning sunlight per day. Even a short step outside can help to reset your circadian rhythms and improve your sleep cycle.
In addition to taking breaks and seeking sunlight, staying hydrated is important for maintaining focus and alertness. Drinking plenty of water throughout the day will help you avoid dehydration, which can impact your ability to stay awake and concentrate.
While taking breaks and going outside can help promote wakefulness, it's important to remember that these are short-term solutions. Prioritising sleep and addressing any underlying sleep issues is crucial for maintaining focus and overall well-being.

Block out noise and light to improve your ability to focus
Light and noise can be major distractions when you're trying to focus. Here are some tips to help you block them out and improve your concentration:
Blocking Out Noise
- Use noise-cancelling headphones or a loud fan to create white noise, which can help mask unwanted sounds. White noise apps are also available and can be useful if you need to focus while travelling or in a busy environment.
- Earplugs are a cheap and effective way to block out sound. Look for ones with a Noise Reduction Rating (NRR) of 33 or higher.
- Rearrange furniture and use soft furnishings to help muffle noise. Thick rugs, curtains, pillows, and blankets can all help to absorb and block sound.
- Meditation can help you to focus and block out distractions. Try meditating for 20 minutes in the morning to set yourself up for the day.
- Listen to music that will fade into the background, such as light acoustic pieces or "elevator music". Alternatively, try nature sounds like rain or ocean waves, which can be soothing as well as blocking out other noises.
Blocking Out Light
- Use heavy curtains or drapes to block out light from windows. Textured fabrics like velvet or microfiber work best, and adding pleats or ruffles can provide even more coverage.
- Block gaps around doors with towels, blankets, or thick rugs to prevent light (as well as noise and drafts) from entering the room.
- Use a lamp or focused lighting to illuminate only the area you need, keeping the rest of the room dark.
Remember, taking breaks and reducing distractions like multitasking and notifications can also help improve your focus.

Frequently asked questions
While it is not advisable to go without sleep, there are a few things you can do to help you focus when you haven't had enough sleep:
- Take a short nap—a 20-30 minute nap can help restore your vitality.
- Drink water—staying hydrated will help keep you alert.
- Take breaks—go for a walk outdoors to get some sunlight and light exercise, both of which stimulate alertness.
- Eliminate distractions—turn off your phone and log out of social media accounts to help you focus on the task at hand.
- Breathe deeply—increasing the blood flow to your brain will help improve your focus.
Sleep deprivation impairs our ability to focus, furthers distractions, and affects our working memory. It also slows down our reaction times and impairs our ability to take in new information or react to dangerous situations.
Most sources recommend getting 7-8 hours of sleep per night. However, a Gallup study found that people are getting an average of 6.8 hours of sleep, with 46% of those surveyed under the age of 50 getting less than 6 hours of sleep each night.
Here are a few tips to help you get a better night's sleep:
- Practice good sleep hygiene—use your bed only for sleeping and sex, block out noise and light, and stick to a consistent sleep schedule.
- Avoid caffeine and alcohol close to bedtime—caffeine interferes with your sleep hormones, while alcohol can interrupt your sleep later in the night.
- Exercise earlier in the day—finish exercising at least 3 hours before bedtime, as exercise stimulates the brain.
- Watch your diet—avoid foods that cause heartburn and don't eat too late, as lying down after eating can cause sleep-disturbing heartburn.
If you're having trouble falling asleep, try to identify and address any underlying causes, such as a medical condition or medication that may be interfering with your sleep. You can also try some relaxation techniques, such as deep breathing or counting backwards from 300 in multiples of three. If you're still struggling, consider consulting a sleep specialist for further guidance.
