What is sleep and why do we need it?
Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings. It is distinguished from wakefulness by a decreased ability to react to stimuli, but more reactive than a coma or disorders of consciousness. Sleep occurs in repeating periods, in which the body alternates between two distinct modes: REM sleep and non-REM sleep.
Scientists are still discovering all the reasons we need sleep, but some benefits of sleep that have been well-established include:
-
Memory consolidation and learning - While we sleep, our brain repeats patterns of neural activity that it experienced during the day, which appears to strengthen brain connections and help consolidate memories and learning from the previous day.
-
Energy replenishing - During sleep our bodies are restoring and repairing themselves on a cellular level. Growth hormone is released while we sleep which aids in tissue growth and muscle repair. Adenosine, a chemical that builds up in the body during the day and causes drowsiness, is cleared out during sleep.
-
Cognitive function - Not getting enough quality sleep can significantly impact our cognitive performance, including concentration, problem-solving abilities, and decision making skills.
-
Emotional regulation - Sleep helps regulate our emotional processing and response. It appears to be important for our ability to interpret emotions and behave appropriately in emotionally charged situations.
-
Metabolism and appetite regulation - Hormones and genes involved in appetite regulation and metabolic pathways are influenced by sleep. Studies show poor sleep is linked to weight gain and an increased risk of obesity and metabolic diseases.
-
Cardiovascular and immune health - Sleep maintains a healthy balance of important hormones that regulate cardiovascular and immune function. Disrupted sleep is linked to a higher risk of heart disease, stroke, and inflammatory diseases.

Importance of sleep for mental and emotional wellbeing
Without sufficient, quality sleep our mental and emotional wellbeing can deteriorate rapidly. Here are some key ways lack of sleep impacts our mental health:
-
Increased stress and poor coping - Adequate sleep is important for controlling our stress response and coping with daily challenges in a healthy way. Lack of sleep dysregulates stress hormones impairing our ability to handle stressors.
-
Mood changes - Sleep deprivation is linked to mood changes such as irritability, anxiety and depressed mood. Over time, poor sleep can potentially increase vulnerability to mood disorders like depression.
-
Impaired motivation - Motivation and drive can take a significant hit without adequate sleep. Getting extra sleep may temporarily restore lost motivation.
-
Impulsivity and risk-taking - Imaging studies show lack of sleep impacts prefrontal brain regions involved in self-control. This can lead to increased impulsivity, impaired judgment and riskier decision making.
-
Cognitive distortions - Poor sleep is linked to cognitive style changes like overgeneralizing, emotional reasoning, and simplistic black and white thinking which can feed into dysfunctional thought patterns and mental health issues.
Importance of sleep for physical wellbeing
While mental health is profoundly influenced by sleep, our physical wellbeing is also intimately connected to proper sleep habits. Some key links include:
-
Cardiovascular health - Even relatively small amounts of lost sleep significantly raise risk of conditions like heart attack, stroke, hypertension and irregular heart rhythms over the long term.
-
Diabetes risk - Poor sleep associates with insulin resistance, a precursor to type 2 diabetes. Studies find each hour less sleep corresponds to a 23% higher risk of developing diabetes.
-
Pain perception - Not getting enough sleep reduces our ability to modulate pain perception and increases pain sensitivity. This may exacerbate conditions like arthritis and headaches.
-
Immune function - White blood cells and antibodies that keep us healthy require sleep. Poor sleep weakens our immunity opening the door to infections, colds and possibly even cancer risk over the long run.
-
Gastrointestinal issues - Lack of sleep can trigger or exacerbate digestive problems like acid reflux, ulcers, constipation and inflammatory bowel disease in genetically susceptible individuals.
-
Accident risk - Sleep deprivation massively impairs cognitive and motor functioning equivalent to being drunk. Too little sleep substantially raises risk of workplace, driving and other accidents and injuries.
Tips for getting better quality sleep
With an understanding of why sleep is so important for wellbeing, here are some tips for prioritizing goo sleep hygiene:
-
Stick to a consistent sleep-wake schedule, including on weekends. Going to bed and waking at a set time programs your body's circadian rhythms.
-
Avoid screens before bed. Blue light from screens suppresses melatonin production and stimulates your brain reducing sleepiness.
-
Create a relaxing bedtime routine to signal to your body that it's time to wind down. Include calming activities like reading or gentle yoga.
-
Make sure your bedroom is cool, dark and quiet. Address any noise, light or temperature issues that could disrupt your sleep.
-
Limit daytime napping to under 30 minutes and only when truly necessary. Napping can interfere with nighttime sleep.
-
Avoid heavy meals, caffeine and vigorous exercise too close to bedtime which can disrupt sleep.
-
Manage stress through techniques like journaling, relaxation practices and mindfulness. Chronic stress is a leading cause of poor sleep.
-
If problems persist, consult your doctor to rule out underlying medical issues or sleep disorders that require treatment. Keep a sleep diary to help assess issues.
Hopefully this overview on Dealnew has highlighted the profound importance of sleep for our overall mental and physical wellbeing. Prioritizing quality sleep should be a non-negotiable part of any healthy lifestyle. With diligent sleep hygiene practices, we can reap all the restorative benefits of a good night's slumber.
