Take a power nap: 20 minutes of uninterrupted sleep can restore fatigue
Napping is a common practice worldwide to restore energy levels during the day. A power nap of 20 minutes is a short period of uninterrupted sleep that can help improve energy, increase mental focus and creativity, and enhance physical performance. It can also help reduce errors and improve memory retention for newly learned concepts.
The benefits of power napping are well-supported by scientific studies. For instance, a 2004 Stanford University study found that participants who were allowed to sleep as long as they wanted reported more vigour and less fatigue. Similarly, a study by the University of California, Berkeley, discovered that a brief 10-minute nap is usually enough to boost energy levels.
However, it is important to note that napping for too long or too close to bedtime can interfere with your nighttime sleep. As such, it is recommended to keep naps under 30 minutes and to finish napping a few hours before bedtime.
Additionally, the effects of power napping can be enhanced by combining it with other strategies. For example, a nap followed by a cup of coffee may provide an even bigger energy boost, according to the American Academy of Sleep Medicine. Furthermore, regular exercise, spending time outdoors, and managing stress through activities like deep breathing or counselling can all contribute to increased energy levels and improved sleep quality.
While power napping can be beneficial, it is important to prioritize getting sufficient and quality sleep at night. Sleep deprivation can have negative impacts on cognitive performance and reaction times, and it may be advisable to consult a medical professional if you consistently struggle to get enough sleep.

Get active: exercise increases your core metabolic rate and sustains energy
Exercise is a great way to increase your core metabolic rate and sustain energy, even when you're sleep-deprived.
Firstly, regular exercise can boost your metabolism, which is the rate at which your body burns calories for energy. The more you move, the more calories you burn, even when you're at rest. For example, a 2011 study found that 45 minutes of vigorous cardio exercise increased the metabolic rate for 14 hours post-workout. This doesn't necessarily mean you have to hit the gym; you can also take the stairs instead of the elevator, park further away from your office, or walk around your house during a phone call. Even a 10-minute walk can increase your energy levels for two hours.
Secondly, exercise can improve your quality of sleep. When you exercise, you're more likely to sleep soundly, and getting a good night's rest is crucial for maintaining a healthy metabolic rate. Lack of sleep can disrupt the hormone balances in your body, which slows down your metabolism and increases your risk for weight gain.
Thirdly, exercise can give your cells more energy to burn and circulate oxygen. It can also lead to higher brain dopamine levels, which helps elevate your mood.
Finally, building muscle through strength training or lifting weights can help increase your metabolism, as muscle is more metabolically active than fat. A 2022 review suggested a strong link between high muscle mass and metabolic rates.
Remember, it's essential to listen to your body and not overdo it. If you're exhausted, opt for light or moderate exercise, and make sure to get enough rest.

Expose yourself to sunlight: natural light helps you feel alert and improves your mood
Sunlight has a positive impact on your mood and energy levels. Sunlight influences the levels of neurochemicals in the brain, such as serotonin, which is associated with boosting mood and helping a person feel calm and focused. Exposure to sunlight is thought to increase the brain's release of serotonin.
Without enough sun exposure, your serotonin levels can dip, and low serotonin levels are associated with a higher risk of major depression with a seasonal pattern (formerly known as Seasonal Affective Disorder or SAD). SAD is a form of depression triggered by the changing seasons, often occurring when people spend more time indoors during the winter and have less opportunity for exposure to natural light.
To combat this, aim for at least 30 minutes of sunlight a day. Sleep experts recommend an hour of morning sunlight if you have insomnia. If you live in a place with little sunlight, consider using a light therapy lamp, which is designed to simulate natural sunlight. Light therapy has been shown to improve mood and balance neurochemicals, particularly during seasons with less sunlight.
Additionally, sunlight exposure can provide other health benefits. For example, exposure to ultraviolet-B (UV-B) radiation in sunlight causes the skin to produce vitamin D, which is essential for bone health. Just 5 to 15 minutes of sunlight on your skin 2-3 times a week is enough to boost your vitamin D levels. However, be mindful that excess sun exposure is linked to an increased risk of skin cancer, so be sure to protect your skin with sunscreen, protective clothing, or a hat if you'll be in the sun for longer periods.

Consume caffeine in moderation: it will give you a boost, but too much can impact sleep
Caffeine is a well-known and widely used stimulant that can help you stay awake and boost your energy levels. It is rapidly absorbed by the body, typically within 45 minutes, and reaches its highest levels in the bloodstream within one to two hours. It is a central nervous system stimulant that blocks sleep-promoting receptors in the brain, helping you stay alert and awake.
While caffeine can provide a much-needed energy boost, it is important to consume it in moderation. Excessive caffeine intake can lead to negative side effects such as increased anxiety, headaches, confusion, upset stomach, and high blood pressure. It can also disrupt your sleep, especially if consumed close to bedtime. Caffeine has a long half-life, typically ranging from one and a half to nine hours, and can stay in your system for up to eight hours, reducing your sleep time and quality.
To avoid negative consequences, it is recommended to keep track of your caffeine intake and consume it in moderation. According to the Mayo Clinic, it is generally safe for healthy adults to consume up to 400 milligrams of caffeine per day, which is equivalent to about two to five standard cups of coffee. However, it's important to note that tolerance to caffeine varies from person to person, depending on factors such as age, body mass, overall health, and genetic factors.
If you find yourself consuming too much caffeine, it is advisable to gradually decrease your intake rather than abruptly stopping, as sudden cessation can lead to withdrawal symptoms such as headaches, nervousness, and fatigue. Additionally, certain beverages, such as filtered coffee, have lower levels of compounds that can negatively impact health, so choosing your caffeine sources wisely can help mitigate potential negative consequences.
In conclusion, caffeine can be a useful tool to stay active and boost your energy levels, but it should be consumed in moderation and with awareness of its potential impact on sleep and overall health.

Plan your day: sleep deprivation slows cognitive speed, so push non-priority tasks to tomorrow
Sleep deprivation can slow down cognitive performance, including alertness, memory, attention, and decision-making abilities. To stay active and productive during periods of sleep deprivation, it is crucial to plan your day effectively and prioritize essential tasks. Here are some strategies to help you manage your day when dealing with sleep deprivation:
Prioritize your tasks: Identify the most critical and urgent tasks that require your immediate attention. Focus on completing those tasks first to make the most of your time and energy. Delegate or postpone non-essential tasks if possible.
Break down complex tasks: When dealing with sleep deprivation, it can be helpful to break down complex or time-consuming tasks into smaller, more manageable steps. This can make them feel less overwhelming and help you stay focused.
Set realistic goals: Recognize that your productivity may be lower than usual due to sleep deprivation. Set realistic goals for the day, considering your energy levels and cognitive capacity. Don't overwhelm yourself with an overly ambitious to-do list.
Focus on one task at a time: Multitasking can be challenging when sleep-deprived, as it further divides your attention. Instead, try to focus on one task at a time and give it your full attention. This can help improve the quality of your work and reduce the risk of errors.
Take regular breaks: Give yourself permission to take short breaks throughout the day. Stepping away from your tasks for a few minutes can help refresh your senses and improve your focus when you return. Use these breaks to stretch, get some fresh air, or engage in a quick energizing activity.
Stay hydrated and well-nourished: Drink plenty of water and eat nutritious meals to fuel your body and maintain your energy levels throughout the day. Avoid excessive caffeine intake, as it can disrupt your sleep further and contribute to a vicious cycle of sleep deprivation.
Remember, while these strategies can help you manage your day during periods of sleep deprivation, they are not long-term solutions. Prioritize getting sufficient and quality sleep as soon as possible to restore your cognitive abilities and overall well-being.
