It is commonly believed that getting less sleep can make one feel more energized and even improve mood. While this may be true for some, it is not a sustainable practice and can have serious health consequences. When an individual does not get enough sleep, their body produces more of the stress hormone cortisol and the alertness-boosting hormone adrenaline to compensate. This can lead to increased stress levels and negative consequences for overall health. Additionally, while sleep loss can improve the moods of those with depression, the improvements are short-lived and disappear when adequate sleep is achieved. Therefore, while it is possible to feel better on less sleep in the short term, it is not a sustainable solution and can lead to health issues over time.

What You'll Learn
A surge in cortisol and adrenaline
Sleep is essential for human survival. Most people need between seven and nine hours of sleep each night, but this range varies from person to person. Some people may feel better with less sleep due to a surge in cortisol and adrenaline, their brain's reward system firing up, or subjective adaptation to sleep loss.
Cortisol is a hormone produced by the hypothalamic-pituitary-adrenal (HPA) axis, which includes the hypothalamus and pituitary gland in the brain, as well as the adrenal glands above the kidneys. It is often associated with stress and plays a role in the fight-or-flight response. Cortisol production typically follows a circadian rhythm, with levels dropping around midnight and peaking about an hour after waking up. Sleep disturbances can disrupt this rhythm, leading to increased cortisol production during the day.
When you don't get enough sleep, your body produces more cortisol and adrenaline to keep you alert. Research shows that even sleeping for 5.5 hours can increase cortisol levels the next evening. High cortisol levels can have negative consequences, including sleep problems, weight gain, and increased risk of cardiovascular issues.
While a surge in cortisol and adrenaline may provide a temporary boost in energy, it is not a sustainable solution. Adequate sleep is crucial for overall health and well-being. Sleep loss can increase negative emotions, impair cognitive functioning, and have long-term impacts on the body.
If you consistently feel better with less sleep, it may be beneficial to consult a healthcare professional. They can help identify any underlying sleep disorders, such as sleep apnea, and provide guidance on improving sleep quality and duration.

The brain's reward system firing up
While it is generally recommended that adults get between seven and nine hours of sleep each night, some people claim to feel better with less sleep. This phenomenon may be explained by the brain's reward system firing up in response to sleep loss.
Research has shown that sleep loss increases reactivity in the brain's reward system. This heightened reactivity can lead to improved responses to both positive and negative stimuli, as well as feelings of giddiness or euphoria. The brain becomes more sensitive and energised the longer one stays awake. This can result in a strange buzz of energy, making individuals feel more alert and energised despite the negative consequences of sleep deprivation.
The brain's reward system is closely linked to the production of certain hormones and neurotransmitters. When individuals do not get enough sleep, their bodies produce higher levels of cortisol and adrenaline, which are associated with increased alertness and energy. However, high cortisol levels can also lead to negative side effects such as sleep problems, weight gain, and increased risk of cardiovascular issues.
Additionally, the brain's reward system can be influenced by the synaptic connections that are formed during wakefulness. In individuals with depression, staying awake for extended periods can lead to short-term relief from depressive symptoms. This is because the lack of sleep improves communication between the amygdala and the anterior cingulate cortex, two regions of the brain closely associated with mood regulation. However, these improvements in mood are usually temporary and disappear once the individual gets more sleep.
While it is intriguing to consider the potential benefits of reduced sleep, it is important to remember that adequate sleep is crucial for overall health and well-being. Sleep deprivation can lead to negative consequences such as increased stress levels, impaired concentration, and a weakened immune system. Therefore, while the brain's reward system may provide a temporary boost in certain situations, prioritising healthy sleep habits is essential for long-term health and optimal brain function.

Subjectively adapting to sleep loss
Secondly, the concept of sleep inertia is important to understand. Sleep inertia is the groggy feeling we experience when we first wake up. Interestingly, sleep inertia can be more intense and last longer when we are sleep-deprived. So, if we consistently get less sleep, we may eventually experience less sleep inertia, making us feel more energised when we wake up, even though we've technically had less sleep.
Additionally, the timing of our sleep also matters. There is a window of time, typically between 10 pm and midnight, that is considered ideal for sleep. Sleeping during this window is believed to be more restorative than sleeping at other times. For example, sleeping from 10:30 pm to 5:30 am for seven hours is considered more beneficial than sleeping from 12:30 am to 7:30 am for the same duration. Therefore, adjusting our sleep schedules to align with this optimal window can make us feel more rested, even if we're sleeping for a shorter duration.
It's worth noting that while some people genuinely feel better with less sleep due to unique genetic factors, such as those with Short Sleeper Syndrome (SSS), for most individuals, chronic sleep deprivation can have detrimental effects on overall health and well-being. The negative consequences of sleep loss can include increased stress levels, impaired concentration and problem-solving abilities, and a higher risk of hallucinations and seizures. Therefore, while the body may subjectively adapt to sleep loss in the short term, prioritising adequate sleep is crucial for long-term health and optimal functioning.

Improved mood in people with depression
While it is generally recommended that most adults get between seven and nine hours of sleep per night, some people report feeling better with less sleep. This phenomenon may be explained by an increase in the production of the stress hormone cortisol, which can provide a temporary boost in energy levels. However, it is important to note that adequate sleep is crucial for physical and mental health, and sleep deprivation can have serious negative consequences.
Research has shown that sleep loss can improve the moods of individuals with depression. A study found that staying awake all night improved depressive symptoms in 40-60% of participants. However, these improvements were short-lived and disappeared when participants returned to a normal sleep schedule. Another study found that individuals with insomnia were five times more likely to develop depression, highlighting the complex relationship between sleep and mental health.
The link between sleep and depression is bidirectional, meaning that depression can also lead to sleep disturbances. People with depression may experience difficulty falling asleep or staying asleep, further exacerbating their symptoms. Additionally, daily stressors can contribute to nighttime wake-ups and make it harder to fall back asleep.
While sleep deprivation may provide temporary relief from depressive symptoms, it is not a sustainable or recommended treatment option. The improvements in mood are short-lasting, and inadequate sleep can have negative consequences on overall health and well-being. Instead, individuals with depression should focus on improving their sleep habits and seeking professional help if needed.
In some cases, addressing sleep problems in conjunction with depression treatment may lead to improved outcomes. Cognitive behavioral therapy for insomnia (CBT-I), when combined with depression treatment, has been shown to improve sleep in individuals with depression and may increase the chances of remission. Therefore, it is crucial to recognize the connection between sleep and mental health and to prioritize getting enough sleep to support overall well-being.

Short Sleeper Syndrome (SSS)
Natural short sleepers with SSS have a minimal sleep requirement and do not purposefully restrict or avoid sleep. Their short sleep pattern is consistent, persisting on weekends and holidays. The pattern usually begins in childhood or adolescence and continues into adulthood. Researchers have identified gene changes in natural short sleepers, specifically mutations in the DEC2 and ADRB1 genes. These genetic changes are believed to enable people with SSS to feel refreshed with less sleep.
Healthcare providers do not consider SSS a sleep disorder, and individuals with the condition do not require further testing or treatment. However, if you suspect you have an unhealthy sleep pattern, your doctor may recommend certain laboratory tests, such as a polysomnography or sleep study, to evaluate your sleep patterns and check for signs of a sleep disorder.
While SSS allows individuals to function well with less sleep, it is important to distinguish it from sleep deprivation. Sleep deprivation occurs when an individual does not get sufficient sleep to function properly, which can have negative consequences for health and well-being. Unlike SSS, sleep deprivation can lead to cognitive impairments, such as difficulty thinking clearly, slower reaction times, and concentration issues. It can also increase the risk of chronic health problems like obesity, diabetes, heart disease, and a weakened immune system.
If you are unsure whether you have SSS or are experiencing sleep deprivation, consider keeping a sleep diary or using sleep tracking apps or wearable technology to monitor your sleep duration and quality. Evaluating your alertness, functionality, and overall health throughout the day can provide insights into your sleep needs. Maintaining good sleep hygiene and consulting with a healthcare professional can help optimize your sleep and enhance your overall well-being.

Frequently asked questions
When you don't get enough sleep, your body produces more of the alertness-boosting hormones cortisol and adrenaline to get you through the day. Sleep loss can also improve the moods of those with depression. However, this is only a temporary improvement and can lead to serious health consequences in the long term.
While some people might be able to survive on very little sleep, most people require a minimum of 7 hours each night to function properly. If you are not feeling well-rested after a full night's sleep, it is necessary to speak to a healthcare provider as it could be a symptom of a sleep disorder or other health condition.
Most human beings need 7-9 hours of sleep each night. This range varies by individual and can depend on other factors, such as whether you are healing from an injury. If you feel rested when you wake up and can function for the whole day without chemical assistance, you are probably getting enough sleep.
