What You'll Learn
Drink caffeine in moderation
While caffeine can help when you need an energy boost, it's important to consume it in moderation. Sleep disorders expert Joyce Walsleben, PhD, of the NYU School of Medicine, advises against overdoing it. While two cups of coffee will give you an energy boost, drinking more than that is unlikely to make you more alert, especially if you're a regular consumer of caffeinated drinks. This is because, as Jeffrey Durmer, MD, chief medical officer at FusionSleep Center in Atlanta, explains, when you're sleep-deprived, sleep hormones collect in the brain throughout the day, and drinking excessive amounts of caffeine won't stop that process.
Caffeine can be a helpful tool in certain situations, such as for workers who have been sleep-deprived, including military personnel, first responders, and shift workers. It can provide an energy boost and potentially improve physical performance and enhance cognitive ability. However, it's important to remember that caffeine is not a substitute for adequate sleep, and there are risks associated with consuming too much. Excessive caffeine intake can impact your sleep the next night, leading to a cycle of sleep deprivation and increased caffeine dependence.
To ensure you're consuming caffeine in moderation, be mindful of your daily intake and try to curb your overall caffeine intake if you find yourself relying on it too heavily. Listen to your body and be aware of the signs of overconsumption, such as jitters, increased heart rate, or difficulty sleeping. Additionally, try to avoid drinking coffee too late in the day, as it can disrupt your sleep schedule.
It's worth noting that individual sensitivity to caffeine can vary, so pay attention to how your body responds to different amounts. If you find that caffeine makes you feel anxious or interferes with your sleep, consider reducing your intake or switching to less caffeinated beverage options. Remember, the goal is to use caffeine as a tool to support your energy levels without letting it disrupt your sleep or become a crutch.

Drink water throughout the day
Drinking water is essential to life, and staying hydrated is crucial for your overall health and well-being. Water is involved in several bodily functions, including carrying nutrients and oxygen to cells, regulating body temperature, lubricating joints, and protecting organs and tissues. Dehydration can negatively impact your sleep-wake cycle and the overall duration of your sleep.
Drinking water throughout the day is an important habit to maintain adequate hydration levels. Here are some tips to help you stay hydrated:
- Carry a reusable water bottle with you and sip from it regularly. A reusable bottle is environmentally friendly, and seeing the bottle will remind you to drink water.
- Aim for around two liters of water per day, but adjust this amount based on factors such as exercise, breastfeeding, or illness, which may increase your fluid needs.
- If you don't enjoy plain water, try flavoring it with lemon, mint leaves, or fresh berries. You can also increase your water intake by consuming fruits and vegetables with high water content, such as watermelon, pears, oranges, spinach, squash, and carrots.
- Drink water before bed to stay hydrated through the night. However, be mindful that drinking too much before bed may interrupt your sleep due to nighttime bathroom trips. Aim to drink a small amount, and use the bathroom right before sleeping to start with an empty bladder.
- Avoid excessive caffeine and alcohol consumption, as these are diuretics that can contribute to dehydration. Limit their intake, especially in the hours before bedtime, to prevent waking up to urinate.
By drinking water throughout the day and staying hydrated, you'll feel more energized and alert, which can help you power through the day even when you haven't had enough sleep.

Get sunlight and fresh air
Sunlight and fresh air are incredibly beneficial for your body and its natural sleep-wake cycle. Light is an important cue for your body's sleep cycle, and your body uses light exposure to determine when it's daytime and when it's nighttime.
When you wake up, getting direct sunlight can benefit your sleep patterns and improve your sleep quality. Sunlight helps your body make serotonin, a brain chemical that plays an important role in your well-being. Morning sunlight also helps your body produce melatonin, a hormone that tells your body when it's time to go to sleep and when it's time to wake up. When you're exposed to sunlight in the morning, your nocturnal melatonin production occurs sooner, and you'll enter sleep more easily at night.
Getting morning sunlight can also help you get enough vitamin D, which is important for keeping your immune system strong and maintaining good mental health. It can also help heal any skin conditions you may have and protect your skin from potential damage.
To get the most benefit from sunlight, try to get outside within the first hour of waking up. Spend 30 to 45 minutes in direct sunlight, without wearing a sun visor or sunglasses, as this will reduce your eyes' access to full sunlight. If you can, take a walk first thing in the morning to get sunlight and exercise at the same time.
If you can't get direct sunlight, light therapy is a good alternative. Light therapy can be done using natural sunlight or artificial light boxes that emit bright light similar to sunlight.

Take a nap, but not for too long
Taking a nap is a great way to recharge your body and mind, but it's important not to nap for too long. Napping for too long can make you feel even more drowsy and groggy, and it may also interfere with your sleep at night, especially if you nap too close to bedtime.
The ideal nap length is around 20 to 25 minutes. This is enough to boost your energy levels without leaving you feeling groggy when you wake up. If you nap for longer than 30 minutes, you risk entering a deeper sleep, which can make it harder to wake up and may even lead to diminished performance throughout the rest of the day.
To make the most of your nap, find a quiet and comfortable spot where you're unlikely to be disturbed. Set an alarm for 20 to 25 minutes and try to time your nap for the early afternoon when your body naturally experiences a dip in energy. If you nap too late in the day, you might find it harder to fall asleep at night.
It's also important to assess why you might be feeling sleepy during the day. Are you getting enough sleep at night? If not, consider improving your sleep habits and bedtime routine. While napping can be a helpful short-term solution, it's important to address any underlying sleep issues to ensure you're getting the restorative sleep you need.

Avoid ultra-processed foods
While a single night of poor sleep won't harm your health in the long term, you may feel tired and irritable the next day. To help you wake up and get through the day, try to expose yourself to natural light and engage in light physical activity, such as a short walk. You can also try drinking a cup of coffee and then taking a 25-minute nap—a combination that should leave you feeling energized for at least four hours. Prioritize important tasks and try to limit your workload for the day.
To help you feel more energized in the long term, it's important to develop healthy habits, including a nutritious diet. One way to improve your diet is to avoid ultra-processed foods. Ultra-processed foods are typically manufactured using industrial methods and ingredients that you wouldn't find in your kitchen or use in home cooking. They often contain high levels of saturated fat, salt, and sugar, and numerous additives such as preservatives, emulsifiers, sweeteners, and artificial colors and flavors.
The NOVA food classification system categorizes food into four groups based on the extent of processing. Ultra-processed foods fall into the fourth category and are significantly altered from their natural state. They are often packaged, heavily processed products found at fast-food restaurants and gas stations. Examples include soda, chips, candy, fast food, and energy bars.
To reduce your consumption of ultra-processed foods, try to prioritize unprocessed or minimally processed foods, such as fresh fruits, vegetables, milk, fish, pulses, eggs, nuts, and seeds. These foods have no added ingredients and are only slightly altered from their natural state. Cooking at home, packing your lunch, and increasing your fruit and vegetable intake can also help you avoid ultra-processed foods.
When it comes to cheese, opt for traditional varieties like Cheddar, Brie, mozzarella, and Edam, which are categorized as processed rather than ultra-processed. Buying cheese in a block and slicing it yourself is healthier and more economical than purchasing pre-sliced options, which are often highly processed.
