There are several reasons why you might feel more energised after sleeping less. Firstly, the amount of sleep required varies from person to person, with some people requiring less sleep due to genetics or conditions such as Short Sleeper Syndrome (SSS). Additionally, the quality of sleep matters; uninterrupted sleep can lead to feeling more refreshed than a longer sleep filled with disturbances. Furthermore, the timing of sleep also plays a role, with sleep obtained between 10 p.m. and midnight considered more restorative. Moreover, the sleep cycle stage at which a person wakes up can impact their energy levels, with light sleep often resulting in feeling more alert than deep sleep. Finally, temporary biological changes, such as increased cortisol and the amplification of the brain's reward system, can contribute to feeling energised after a short sleep. However, it is important to note that the positive effects of reduced sleep are often short-lived and chronic sleep deprivation can lead to adverse health consequences.

Feeling better may be an illusion due to raised stress hormone levels
While some people genuinely do need less sleep, for those without the Short Sleeper Syndrome (SSS) genes, feeling better on less sleep may be an illusion due to raised stress hormone levels.
When we don't get enough sleep, our bodies operate on borrowed energy financed by two natural chemicals: caffeine and cortisol. Caffeine is a stimulant that can banish tiredness and promote mental alertness. However, it can also cause undesirable side effects such as insomnia, sweating, and a racing heart. Cortisol is a stress hormone that keeps the body alert when danger is present and increases energy production during stressful times. Research shows that acute sleep deprivation elevates cortisol levels, leading to a dysregulated hypothalamic-pituitary-adrenal (HPA) axis. The HPA axis plays a crucial role in our stress response, and it goes into overdrive after a period of poor or no sleep. This change in your body's stress response can lead to feelings of increased energy and alertness. However, this is an illusion, as your stress levels are actually higher, and you've lost the ability to have relaxed control.
Additionally, when we miss out on sleep, our brains go into overdrive, and we may feel a strange buzz of energy due to the formation of too many connections between brain neurons, resulting in brain hyperactivity. This temporary high of sleep deprivation is almost always followed by a crash marked by memory problems, mood swings, and trouble concentrating. The long-term consequences of inadequate sleep include high blood pressure, mood problems, weight gain, lowered immune system, obesity, type 2 diabetes, and heart disease.
Therefore, while you may feel better in the short term on less sleep, it is essential to prioritize getting enough restorative sleep to maintain optimal health and avoid the negative side effects of sleep deprivation.

Waking up during light sleep can make you feel more energised
It is generally recommended that most people need between seven and nine hours of sleep each night. However, some people report feeling more energised after sleeping less than the recommended amount.
One reason for this could be that they are waking up during a period of light sleep. When we wake up from a deep sleep, we often feel groggy and slow for a prolonged period. This is because our bodies are going through restorative processes during this stage of sleep. Waking up during deep sleep can also result in us hitting the snooze button or needing a nap later in the day.
To avoid this, we can plan our sleep around our sleep cycles, aiming to wake up during a lighter stage of sleep. This will help us feel more alert and increase our productivity throughout the day.
However, it is important to note that while some people may feel more energised after sleeping less, this may be a short-term effect. In the long term, sleep deprivation can lead to negative side effects such as a lowered immune system, obesity, type 2 diabetes, and heart disease.
Additionally, the feeling of having more energy after sleeping less could be due to temporary changes in the brain's reward system. Research has shown that a lack of sleep amplifies the brain's reward system, leading to an increase in positive emotional experiences and blind optimism.
It is also worth considering other factors that may be influencing sleep quality, such as sleep apnea or snoring, which can impact how rested we feel.

You may feel better due to your body compensating for the lack of sleep
It is important to note that sleep is essential for normal brain functioning and overall health. Most people need 7 to 9 hours of sleep each night, and chronic sleep deprivation can lead to a variety of health issues, including a lowered immune system, high blood pressure, mood problems, weight gain, and even contribute to the development of Alzheimer's disease.
However, some people report feeling more energized after sleeping less. This sensation may be attributed to the body's compensatory mechanisms in response to sleep loss. When you don't get enough sleep, your body goes into a state of stress, and your cortisol production increases. Cortisol is a stress hormone that enhances alertness and energy production during stressful situations. This heightened cortisol level can provide the illusion of feeling better, even though your body is experiencing increased stress.
Additionally, sleep deprivation can amplify the brain's reward system, leading to a temporary high or a sense of blind optimism. This effect has been observed in studies where sleep-deprived individuals exhibit amplified reactivity in their brain's reward networks. However, this temporary boost is typically followed by a crash, marked by memory issues, mood swings, and difficulties with concentration.
It is also worth considering that feeling more energized with less sleep could be a result of improved sleep hygiene or timing your sleep with your sleep cycles. Good sleep hygiene helps you fall asleep faster and reduces interruptions, resulting in more efficient and restorative sleep. Similarly, waking up during a lighter stage of sleep, rather than deep sleep, can make you feel more alert and energized, even if you've slept for a shorter duration.
Lastly, a small percentage of the population may have a unique genetic mutation known as Short Sleeper Syndrome (SSS), which allows them to function optimally with significantly less sleep than the average person.

Temporary changes in the brain's reward system can make you feel more optimistic
It is important to note that while you may feel more energized after a period of sleep deprivation, this is likely to be a short-term effect. In the long term, inadequate sleep can lead to high blood pressure, mood problems, and weight gain.
Research has shown that acute sleep deprivation can elevate cortisol levels, which is a stress hormone that keeps the body alert and increases energy production during stressful times. This can lead to feelings of increased energy and alertness.
Additionally, a 2011 study found that sleep deprivation amplifies the reactivity of the brain's reward networks, leading to an increase in the appraisal of positive emotional experiences. This means that a lack of sleep can make you feel more optimistic and positive. The study also found that this was followed by a "crash" marked by memory problems, mood swings, and trouble concentrating.
Another theory for why sleep deprivation may lead to increased optimism is that when we are awake, our brains continually build synaptic connections. For people with depression, this can cause short-term relief from depressive symptoms.
While it is not fully understood why sleep deprivation can lead to temporary feelings of optimism, it is clear that this is not a sustainable way to manage mental health and that adequate sleep is crucial for overall health and well-being.

You may be sleeping more efficiently, not necessarily less
There are several reasons why you might feel more energised after sleeping less. Firstly, you may have simply improved your sleep hygiene, which means you're spending less time in bed awake or asleep, but still getting the same amount of sleep. This leads to less interrupted sleep, which is more restorative and can positively impact your mood.
Secondly, you may be waking up at the end of a sleep cycle, which can make you feel more energised than if you were to wake up in the middle of one. However, research is mixed on whether waking up during deep sleep or REM sleep will make you feel groggier. Plus, wearable devices aren't very accurate at tracking sleep cycles, so it's hard to tell when you're waking up. Sleep cycles also vary from person to person and can change from night to night.
Thirdly, your body may be operating on borrowed energy from caffeine and cortisol. Caffeine is a stimulant that promotes mental alertness, but it can have undesirable side effects such as insomnia, sweating, and a racing heart. Cortisol is a stress hormone that keeps the body alert when danger is present and increases energy production during stressful times. However, relying on these chemicals instead of adequate sleep can lead to negative side effects and is not a sustainable solution.
Finally, if you have been sleeping more than the recommended amount, you may be experiencing the benefits of sleeping less. Oversleeping has been linked to various health issues, including increased risk of heart disease, obesity, type 2 diabetes, and mental health problems. Additionally, some people have a unique genetic mutation called Short Sleeper Syndrome (SSS), which allows them to function optimally on less sleep. However, for those without SSS, chronic sleep deprivation can take a toll on overall health and cognitive function.
