What You'll Learn
Consume caffeine in moderation
Consuming caffeine in moderation can help you stay alert and boost your energy. However, it is important not to overdo it. Caffeine can be beneficial in moderation, with one or two cups of tea or coffee in the morning or early afternoon giving you the boost you need to get through the day.
Consuming more than two cups of coffee will not make you more alert. Excessive caffeine consumption can lead to negative side effects such as anxiety, jitteriness, sweating, and heart palpitations. It can also disrupt your sleep, so it is best to limit your intake and avoid caffeine after 4 pm.
Caffeine has a half-life of about five hours, so it is best to avoid consuming it within 12 hours of your bedtime to ensure it does not interfere with your sleep. Caffeine blocks the effects of adenosine, a neurotransmitter that makes you feel sleepy, so it is important to give your body enough time to eliminate it from your system before you try to sleep.
If you are experiencing sleep issues, it is best to limit your caffeine intake to the morning hours to avoid disrupting your sleep onset.

Avoid sugar, carbs, and processed foods
When you're sleep-deprived, it's best to avoid sugar, carbs, and processed foods. While these foods will give you a quick energy boost, it won't last long and you'll likely experience a subsequent crash due to rapidly declining blood sugar levels.
Sugar and refined carbohydrates—such as those found in sweets, juices, white bread, white rice, and soda—cause spikes in blood sugar and are linked to an increased risk of obesity, heart disease, and tooth decay. These spikes can prompt a release of insulin, leading to a blood sugar crash. If glucose levels in the brain drop too low, your body may release hormones such as adrenaline to try to bring glucose levels back to a safe level. The effects of these hormonal countermeasures can be enough to wake you from sleep.
Consuming more non-fiber carbohydrates can increase the number of times you wake up during the night. A diet rich in fiber, with reduced intake of sugars and other non-fiber carbohydrates, may improve sleep depth.
Additionally, a high-carbohydrate meal is more likely to cause sleepiness than a low-carbohydrate meal. High-carbohydrate foods and drinks that are high in processed sugars and starches can cause your blood sugar to rise quickly, increasing your risk of tiredness.
Instead of reaching for sugary snacks and refined carbs, opt for a balanced diet with extra emphasis on protein-rich foods such as nuts and lean meats.

Exercise at the right time
Exercise is an important part of sleep hygiene and can improve your sleep quality and duration. However, the best time of day to exercise is still a subject of debate.
The Science Behind It
Moderate aerobic exercise increases the amount of slow-wave sleep you get. Slow-wave sleep refers to deep sleep, where the brain and body rejuvenate. Exercise also helps stabilize your mood and decompresses the mind, aiding the natural transition to sleep.
The Timing of Exercise
The optimal time to exercise depends on individual factors such as your chronotype, age, and any underlying health conditions. Some people may find that exercising close to bedtime interferes with their sleep, while others find that the time of day they exercise doesn't make a difference.
Recommendations
- Exercise at least 1 to 2 hours before going to bed. This gives endorphin levels time to decrease and allows the brain to wind down.
- Avoid vigorous exercise within 1 hour of bedtime. This allows enough time for your body to cool down and prepare for sleep.
- Morning or afternoon exercise stimulates the release of melatonin and shifts the circadian rhythm forward, making it easier to fall asleep early.
- If you have insomnia, stick to light to moderate exercise at least 4 hours before bedtime.
- If you frequently wake up during the night, add an evening exercise routine. Resistance or light aerobic exercise performed in the early evening may be best.
- If you struggle to sleep after exercising in the morning, try shifting your workouts to later in the day.
Other Tips for Falling Asleep After Days of No Sleep
- Keep your body hydrated. Dehydration can make you feel more tired.
- Avoid caffeine, especially after 4 pm, as it can disrupt your sleep.
- Avoid sugar and simple carbohydrates, as they can cause an energy crash. Instead, focus on a balanced diet with protein-rich foods.
- Simplify your day and lighten your workload.
- Get exposure to natural light and fresh air, which promote alertness and wakefulness.
- Stick to your regular sleep schedule.

Take a power nap
If you've been awake for days, you're likely experiencing extreme sleep deprivation. While the best course of action is to get a full night's rest, taking a power nap can be a good way to quickly boost your energy levels and alertness. Here are some tips for taking a power nap:
Timing is Everything
The ideal power nap should be around 20 minutes long. This duration allows you to enter the lighter stages of sleep, which will help you feel refreshed and alert when you wake up. Sleeping for longer than 30 minutes can lead to deep sleep, causing you to feel groggy and disoriented upon waking up. Additionally, try to nap during the midpoint of your day, typically between 12:00 PM and 3:00 PM. Napping too late in the day can disrupt your nighttime sleep.
Create the Right Environment
To fall asleep quickly, create a comfortable and optimal sleeping environment. Find a quiet, cool, and dark place to nap. If necessary, use earplugs or a white noise machine to block out noise, and an eye mask or blackout curtains to block out light.
Try a "Coffee Nap"
For an extra boost, try consuming caffeine right before your nap. Caffeine takes about 20-30 minutes to take effect, so it will kick in as you're waking up, leaving you feeling even more refreshed and energized.
Wake Up and Recharge
Although you shouldn't feel groggy after a power nap, it's normal to need a few minutes to fully wake up and get your body back into gear. Give yourself some time to recover and re-center, and plan out the rest of your day.
Remember, power napping isn't for everyone. If you have insomnia or struggle with falling or staying asleep, power napping may disrupt your sleep cycle further.

Avoid driving
Sleep deprivation can have serious effects on your driving ability, and even cause accidents. If you haven't slept for days, it is best to avoid driving completely. Here are some reasons why, along with some tips to help you stay safe:
Impaired Cognition and Performance
Sleep deprivation can impair your cognition and performance, including your attention, judgment, decision-making, coordination, vigilance, and reaction time. These functions are crucial when driving, and impairment can lead to accidents. Even mild and short-term sleep deprivation can cause dangerous driving impairments.
Increased Risk of Microsleeps
Microsleeps are brief losses of consciousness that can last for four to five seconds. While driving at 55 miles per hour, you can travel more than 100 yards during a microsleep, which is plenty of time to cause a crash. Microsleeps become more frequent the longer you stay awake, so it is best to avoid driving if you have been awake for an extended period.
Similar Impairments to Alcohol Intoxication
Being awake for 18 hours straight can make you drive as if you have a blood alcohol level of 0.05, which is close to the legal limit of 0.08. After 24 hours of no sleep, the impairment level is equivalent to a blood alcohol level of 0.1, which is well above the legal limit. Sleep deprivation can impair your driving ability to a similar extent as alcohol intoxication, so it is crucial to avoid driving when sleep-deprived.
Peak Sleepiness Periods
Drowsy driving crashes most frequently occur between midnight and 6 a.m. or in the late afternoon, as these are peak sleepiness periods when people experience dips in their circadian rhythm. If you must drive during these times, stay vigilant for signs of drowsiness and pull over for a short nap if needed.
Safe Alternatives
If possible, use public transportation, taxis, or ask a friend for a ride instead of driving. This will ensure your safety and the safety of others on the road.
In summary, driving when sleep-deprived can be extremely dangerous and put yourself and others at risk. It is best to avoid driving if you have not slept for days and to prioritize getting adequate sleep before getting behind the wheel.
