How sleep deprivation impacts emotional health and cognitive abilities

Sleep deprivation can significantly impact emotional health and cognitive abilities. Andrew Huberman has discussed how lack of sleep, especially REM sleep, can lead to irritability and make people more emotionally reactive, as well as cause a selective difficulty in uncoupling emotions from events of the previous days. When deprived of REM sleep, individuals start to view minor issues as major problems, indicating a shift in emotional stability and tolerance. This emotional instability is seen as one of the most reliable signatures of insufficient sleep, and there is no major psychiatric disorder in which sleep is normal, emphasizing the strong connection between sleep health and emotional wellness 1 2.

Cognitive abilities, such as attention and alertness, are also affected by sleep deprivation. A lack of sleep can reduce one's ability to perform tasks that require sustained concentration. This has been demonstrated through tests that closely resemble the attentiveness needed during activities such as driving. The impaired cognitive performance due to sleep deprivation is often not noticeable to the individual, much like a drunk driver may not realize their impairment. Objective measures, however, clearly show a decline in performance 3.

Additionally, sleep deprivation can disrupt metabolism, which could influence emotional health through its impact on brain and body regulation. Disruptions in sleep have been linked to metabolic syndromes, with a plethora of data pointing to quality sleep as crucial for regulating not just appetite but also specific forms of metabolism that drive specific appetites 4. Sleep also seems to help regulate our "affect," a general state which influences the types of emotions we experience. Tending to one's sleep needs can help create a milieu in the brain that biases the system towards more positive emotional states 5.

Thus, to maintain emotional balance and cognitive functioning, getting a sufficient amount of high-quality sleep regularly is emphasized by Dr. Huberman and other experts featured in his discussions 6.

Studies on sleep related to emotional health have uncovered various significant insights:

• Attachment of Emotion to Experiences: REM sleep is crucial for attaching emotions to particular experiences and unlearning intense or severe emotional responses. It is the stage where we can uncouple emotions from past experiences. Sleep disturbances correlate with emotional and psychological disturbances, leading to hyper-emotionality and a tendency to catastrophize 1.

• Trauma and Sleep: Talking about traumatic events is often counterproductive because it can reactivate emotions without helping individuals process their trauma or find closure before sleep. REM sleep is key in therapy as it allows the emotional intensity of memories to be reduced without the influence of norepinephrine, which could otherwise reinforce trauma's emotional impact 2.

• Emotionality in Menopause: Emotional effects during menopause may be linked to disruptions in temperature and sleep regulation, suggesting sleep deprivation impacts the brain's ability to adjust emotional circuits correctly 3.

  Andrew explains the importance of both slow wave sleep and REM sleep for motor learning, emotional attachment, and unlearning emotional responses. He emphasizes the need to manage one's sleep life, especially during disruptive events, as sleep disturbances can lead to emotional and psychological disturbances.

• General Emotional Instability: Some of the most reliable signs of sleep insufficiency are emotional instability and overreaction to minor issues. There are no major psychiatric disorders where sleep patterns are normal, indicating an intimate association between emotional health and sleep health 4.

• Evoking Positive Emotions: Sleep, especially the absence of norepinephrine during REM sleep, seems essential for uncoupling emotional potential from various experiences. It plays a crucial role in emotional stability by removing unnecessary connections between events 5.

• Alcohol and Sleep: Alcohol consumption, even in moderate amounts, can disrupt sleep quality by fragmenting sleep, reducing REM sleep, and increasing emotional sensitivity 6.

Overall, these studies highlight sleep's profound influence on our emotional well-being and the complexity of its role in processing our emotional experiences.
