Sleep is essential for our health and well-being, and inadequate sleep can have serious consequences. However, many people feel they can work better with less sleep. This perception may be due to several factors, such as a surge in cortisol and adrenaline, the brain's reward system firing up, or subjectively adapting to sleep loss. While you may feel more energized with less sleep, your performance, health, and well-being are likely to suffer in the long run. Understanding the links between sleep and job performance can help individuals prioritize sleep and break the cycle of sleep deprivation.

A surge in cortisol and adrenaline
Sleep is essential for the body to function properly. However, in today's fast-paced world, many people often feel more energized after getting less sleep. This phenomenon can be attributed to several factors, one of which is a surge in cortisol and adrenaline levels.
When an individual does not get sufficient sleep, their body produces more cortisol, a natural steroid classified as a stress hormone. Cortisol is responsible for increasing alertness and providing a temporary boost in energy. While elevated cortisol levels can make a person feel more awake and productive in the short term, it is important to understand that this comes at a cost. Prolonged periods of high cortisol can lead to negative consequences, such as sleep problems, weight gain, and an increased risk of strokes and heart attacks.
Adrenaline, another hormone released during sleep deprivation, contributes to the feeling of heightened energy and alertness. Adrenaline is often associated with the body's "fight or flight" response, preparing the body to take action in stressful situations. This surge in adrenaline can make individuals feel more energized and capable of tackling tasks, even when they are sleep-deprived.
It is worth noting that while a person may feel more energized due to increased cortisol and adrenaline, their performance, health, and well-being are likely to suffer. Sleep deprivation can have detrimental effects on various aspects of an individual's life, including their immune system, problem-solving abilities, emotional regulation, and long-term health.
Additionally, the feeling of having more energy on less sleep could be influenced by other factors, such as coming off medication, starting a workout routine, or experiencing changes in cortisol-regulating factors like stress levels.
In conclusion, while a surge in cortisol and adrenaline can contribute to feeling more energized on less sleep, it is important to prioritize getting adequate sleep to maintain overall health and well-being.

Your brain's reward system firing up
Sleep is essential for keeping your life intact. However, you may sometimes feel more energized on less sleep due to your brain's reward system firing up. When you don't get adequate sleep, your body produces more of the alertness-boosting hormones cortisol and adrenaline to get you through the day. Cortisol is a natural chemical that remains elevated when you don't get enough sleep, providing the illusion that you feel better with less sleep. Caffeine, the most-used drug in the world, also stimulates the production of cortisol.
Procrastination can also cause a dopamine and adrenaline rush, and people often consume caffeine to stay up, which further affects dopamine levels. This creates a messy relationship between procrastination, sleep deprivation, and productivity.
Additionally, when you're sleep-deprived, you may enter an overdrive state, and the long-term health consequences of this can be damaging. Using this stress response to drive productivity is not sustainable. While you may feel more energized due to the surge in cortisol and adrenaline, your performance, health, and well-being will likely suffer.
To improve your sleep, consider improving your sleep hygiene, which addresses factors that interfere with sound sleep. This can include making sure your bedroom is dark, turning off your phones, and ensuring your family and friends know not to disturb you while you sleep.

Subjectively adapting to sleep loss
The idea of subjectively adapting to sleep loss challenges the traditional understanding of sleep needs. It is widely accepted that most adults require seven to nine hours of sleep per night. However, a significant number of people claim to feel better and perform better with less sleep. This discrepancy has sparked interest in understanding how and why some individuals seem to adapt to sleep deprivation.
One explanation for this phenomenon is the role of cortisol and adrenaline. When an individual experiences sleep loss, their body produces higher levels of cortisol, the stress hormone, and adrenaline, which can boost alertness and energy levels. This surge in hormones may lead to a feeling of heightened productivity, even if the individual is not performing at their best. Additionally, external factors such as caffeine consumption can further enhance the effects of these hormones, creating the illusion of improved performance.
It is important to note that while an individual may subjectively feel more energized on less sleep, their health and performance may still be impacted negatively. Sleep deprivation can have far-reaching consequences, including impaired digestion, weakened immunity, reduced brain function, mood disturbances, and increased risk of chronic illnesses. Therefore, while subjectively adapting to sleep loss may provide a temporary boost in energy, it is not a sustainable solution for maintaining optimal health and productivity over the long term.
To break the cycle of sleep deprivation and improve overall well-being, it is crucial to prioritize sleep hygiene and practice healthy sleep habits. This may include establishing a consistent sleep schedule, creating a relaxing sleep environment, limiting caffeine intake, and seeking professional help for underlying sleep disorders or work-related fatigue. By addressing sleep loss and prioritizing adequate sleep, individuals can improve their health, enhance their performance, and achieve sustainable energy levels.

Improved sleep hygiene
Sleep hygiene is a set of practices and routines that help you get better sleep. It involves optimising your environment and habits to achieve improved sleep quality. Here are some ways to improve your sleep hygiene:
Bedroom Environment
- Minimise light entering your bedroom. Consider using light-blocking curtains or shades to block outside light.
- Maintain a comfortable temperature in your bedroom. Most people sleep better in a slightly cool room, around 65°F to 68°F.
- Reduce or mask noise with the use of heavy curtains and rugs to absorb sound, or a sleep machine that provides white noise or soothing sounds.
- Keep your phone away from your bed to avoid disruptions from notifications, buzzing, and light.
- Avoid having work-related items and electronic devices in your bedroom.
- Ensure your mattress and pillows are comfortable and not worn out.
Daily Routines and Habits
- Stick to a consistent sleep schedule by going to bed and waking up at the same time every day, including weekends. This reinforces your body's sleep cycle, making it easier to fall asleep and reducing daytime sleepiness.
- Establish a relaxing bedtime routine that helps you unwind and relax before sleep. This can include activities such as reading, taking a warm bath, stretching, progressive muscle relaxation, or deep breathing exercises. Start your routine 30 to 60 minutes before bedtime, and avoid stimulating activities during this time.
- Get regular exercise, preferably outdoors, as exposure to natural light helps regulate your sleep cycle. Aim for at least 30 minutes of aerobic exercise per day, but avoid exercising too close to bedtime as it may increase your energy levels and body temperature, making it harder to fall asleep.
- Be mindful of what you consume. Avoid caffeine after lunch, as it can interfere with your sleep. Similarly, avoid nicotine and alcohol close to bedtime, as they can stimulate your body and disrupt your sleep. Consume your evening meals at least three hours before bedtime.

The illusion of increased energy
Sleep is essential for our health and well-being, and inadequate sleep can have serious consequences. However, it is common for people to feel more energized and productive on less sleep. This sensation can be attributed to several factors, including the body's chemical responses, the illusion of increased energy, and the impact of external factors.
Firstly, when we don't get enough sleep, our bodies produce more cortisol, the stress hormone, and adrenaline, which can give us a temporary boost in energy and alertness. This increase in cortisol may provide the illusion of enhanced productivity and energy, but it comes at a cost. Elevated cortisol levels can lead to sleep problems, weight gain, and an increased risk of strokes and heart attacks. Additionally, while caffeine can provide a quick boost, it is a drug that continuously stimulates us, masking the need for sleep.
Secondly, the feeling of having more energy on less sleep can be misleading. Sleep inertia, the groggy feeling we experience upon waking up, can be more intense and prolonged during sleep deprivation. However, once we return to a normal sleep pattern, we may feel less sleep inertia and mistakenly attribute this improved morning energy to getting less sleep.
Furthermore, external factors can influence our sleep hygiene and energy levels. For example, coming off medication, starting a workout routine, or working on a stressful project can affect our sleep patterns and make us feel more energized, even if our sleep duration remains unchanged.
While it is tempting to believe that we can function optimally on less sleep, this notion is largely an illusion. Sleep deprivation can have detrimental effects on various aspects of our lives, including our health, productivity, and well-being. To break the exhausting cycle of sacrificing sleep for work, it is crucial to prioritize quality sleep and maintain a healthy sleep schedule.
