Take a short nap, but not too long, and not too late in the day
Napping is a great way to boost your energy levels, but it's important to do it right. The timing of your nap is crucial—aim for sometime after lunch and before 3 pm. This will help you avoid the post-lunch energy slump without affecting your nighttime sleep. If you nap after 3 pm, you might find it harder to fall asleep at night.
Keep your nap short. The ideal nap length is generally considered to be around 20 to 30 minutes. This allows you to rest without entering deep sleep, which can leave you feeling groggy and disoriented. If you nap for longer than 30 minutes, you run the risk of sleep inertia, a period of impaired performance immediately after waking up.
If you're looking to optimize your nap, try drinking a cup of coffee right before you doze off. Caffeine takes about 20 minutes to kick in, so you'll wake up feeling extra refreshed. This technique, known as a "coffee nap" or a "napalatte," can leave you feeling mentally sharp and energized for up to four hours.
It's also important to create a nap-friendly environment. Choose a quiet, dark, and cool place to nap. Use blackout curtains, a sleep mask, or earplugs if necessary to block out light and noise.
Remember, while napping can be a great way to boost your energy, it's not a substitute for a good night's sleep. If you're consistently feeling tired during the day, try to prioritize getting a full night's rest. Additionally, regular exercise, staying hydrated, and eating a balanced diet with good fats, leafy greens, and protein-rich foods can all help naturally boost your energy levels.

Drink caffeine, but not too much, and not too late in the day
Caffeine can be a great way to boost your energy when you haven't had enough sleep. It increases alertness and sharpens your mind. However, it's important to remember that too much caffeine can lead to negative side effects and disrupt your sleep even further.
Firstly, it's important to be mindful of the amount of caffeine you consume. While caffeine can give you a much-needed energy boost, drinking too much can lead to jitters and insomnia. According to experts, two cups of coffee are usually enough to maximize alertness. Consuming more than that, especially when you're sleep-deprived, is unlikely to make you more alert and can interfere with your sleep. Caffeine takes a while to wear off, so it's best to avoid it late in the day. Try to cut off your caffeine intake after 2 pm or, at the latest, 4 pm to ensure you can fall asleep at a reasonable hour.
If you're looking for a quick pick-me-up in the afternoon, a "nap-a-latte" might be the answer. As suggested by sleep medicine expert Michael Breus, you can drink a cup of iced drip coffee as quickly as you can and then take a 25-minute nap. This combination will leave you feeling energized for at least four hours.
In addition to moderating the amount and timing of your caffeine intake, be mindful of the form in which you consume it. Energy drinks, for example, can do more harm than good. Instead, opt for plain black or green tea, or coffee.
While caffeine can provide a temporary boost, it's important to remember that it's not a substitute for a good night's sleep. To truly feel rested and energized, adequate sleep is essential.

Eat a balanced diet, with protein-rich foods, good fats, and leafy greens
Eating a balanced diet is essential to maintaining your energy levels and overall health. A balanced diet includes foods from various groups, such as fruits, vegetables, dairy, grains, and protein.
Protein-rich foods are an important component of a balanced diet. They provide the body with essential amino acids, which are necessary for normal body functioning, growth, and repair. Aim to include a variety of protein sources in your diet, such as lean meats, poultry, fish, eggs, dairy products, beans, pulses, nuts, and seeds. For instance, you could have a kale salad with hazelnuts and soft-boiled eggs, or grilled chicken with vegetables. These foods also provide other important nutrients, such as vitamins, minerals, and healthy fats.
In addition to protein, include a variety of colourful vegetables in your diet, especially dark, leafy greens. These are excellent sources of hydration, minerals, and other nutrients. Whole grains are also a healthy choice, as they provide additional vitamins, minerals, and fibre. Try switching from refined grains, such as white bread and pasta, to whole grain options like brown rice and wholewheat pasta.
When it comes to fats, it's important to choose healthy options like olive oil, especially extra virgin olive oil, which is the least processed type. Avocados are another good source of healthy fats and have been shown to repair cognitive function, which can be particularly beneficial when you're sleep-deprived. However, it's best to avoid deep-fried foods, as they tend to be high in calories and low in nutritional value.
Remember, individual needs may vary, so it's always a good idea to consult with a healthcare professional or a registered dietitian to determine the specific dietary requirements that are right for you.

Exercise, but keep it light or moderate—a 10-minute walk can help
Exercise is a great way to boost your energy when you haven't had enough sleep, but it's important to keep it light or moderate. Overdoing it with vigorous exercise when you're already exhausted can lead to injury. So, instead of an intense workout, opt for a 10-minute walk.
Walking, especially outdoors, has multiple benefits for boosting energy levels. First, it gets your blood pumping, increasing circulation, oxygen supply, and energy levels. Walking pumps oxygen through your veins, brain, and muscles, and this extra oxygen stimulates alertness in the brain. Additionally, sunlight provides natural cues to your body to promote wakefulness.
Even a short walk can have lasting effects on your energy levels. A study by Robert Thayer, a professor at California State University, Long Beach, found that a brisk 10-minute walk increased energy levels for two hours. In comparison, consuming a candy bar for a quick energy boost resulted in lower energy levels after an hour.
If you work at a desk, make sure to get up frequently for short walks. This will not only boost your energy but also help counteract the negative effects of continuous fixation on a computer screen, which can cause eyestrain and worsen sleepiness and fatigue.

Get natural sunlight, and bright light exposure to reduce sleepiness
Sunlight is a natural cue that promotes wakefulness. Sunlight, especially in the morning, can help you sleep better at night by resetting your body's inner "sleep clock". Light is an important cue for your body's sleep cycle, helping it figure out when it's time to go to bed and when it's time to wake up. Sunlight influences the release of melatonin, which controls your sleep cycle.
Exposing yourself to light for its health and sleep benefits is called light therapy. Natural sunlight is the most potent form of light therapy, with an intensity of 100,000 lux. Light boxes that emit artificial light can be helpful alternatives for those unable to get outside in direct sunlight each morning, but they are not the same. Light boxes produce about 10,000 lux or less, and they can be expensive.
Sun exposure has been found to improve the quality and state of sleep, as well as sleep patterns, and it is also associated with higher vitamin D levels, which contribute to maintaining a healthy musculoskeletal system.
To get more sunlight, try going for a walk outdoors. Even a 10-minute walk can help increase circulation, oxygen, and energy levels. If you can't go outside, try sitting near a window or buying a special lamp that mimics the effects of sunlight.

Drink plenty of water, as dehydration can make you feel sluggish. Exercise is another great way to boost your energy, as it releases endorphins and gives you a natural mood boost. Even a 10-minute walk can help, as walking pumps oxygen through your veins, brain, and muscles.
Foods with a low glycemic index, such as whole grains, high-fibre vegetables, nuts, and healthy oils like olive oil, are a good choice. Lean protein and healthy fats can also help—these foods will satisfy you and help you stay full for longer.
