How Sleep Habits Affect Mental Health

May 14

Introduction

Have you been someone who, if woken up before you naturally wake, feels irritable, groggy and develops a headache through the day? Maybe you find it harder to focus, feel less motivated, or become emotionally sensitive over small things. This is probably because your body did not get enough sleep. A good sleep is not just physical rest, it plays a major role in maintaining emotional balance, mental clarity and overall psychological well-being. Various studies have reported that people with insomnia had two-fold risk of developing depression compared to those who did not experience insomnia. There are other evidences that problems with sleeping are associated with variety of mental health conditions, for example, poor sleep has been associated with post-traumatic stress, eating disorders, delusions and hallucinations.

How Much Sleep Is Enough?

The amount of sleep needed for proper functioning of mind and body changes over the course of life. Although sleep needs vary from person to person, American Academy of Sleep Medicine (AASM) recommends the particular duration of sleep for various age groups. For example, newborns between 4 to 12 months typically require around 12 to 16 hours of sleep per day including naps. Children aged 1 to 2 years need 11 to 14 hours of sleep, while those between 3 to 5 years require 10 to 13 hours of daily sleep. School aged children from 6 to 12 years are recommended to get 9 to 12 hours of sleep, while those aged 13 to 18 years need around 8 to 10 hours of sleep. Adults aged 18 and older are advised to get about 7 to 8 hours of sleep per night for optimal health and functioning.

Benefits Of Good Quality Sleep

Research consistently shows that sleep and mental health share a bidirectional relationship. While poor sleep can lead to anxiety or symptoms of depression, existing mental health conditions also make it harder to maintain a good sleep. Getting good sleep at right times is vital not only for mental health, but it also improves our physical health and quality of life. Sleep plays a vital role in mental as well as physical health.

Mental health benefits of good sleep

Regulates emotions.
Controlling behavior and coping with change.
Improves concentration and memory as sleep helps with formation of long-term memories.
Improves learning and problem-solving skills.
Improves attention and boosts creativity.
Sleep deficiency has been linked to depression, suicide and risk-taking behavior.

Physical health benefits

Sleep plays an important role in supporting immune function, tissue repair, metabolism, cardiovascular health and overall disease prevention. Key physical benefits of sleep are as follows:

It boosts immune system by supporting the production of cytokines and other immune cells that help in fighting infections and inflammation.
It helps in healing and repairing of heart and blood vessels, thereby decreasing the risk of cardiovascular diseases like high blood pressure, stroke, or hardening of arteries.
It helps in controlling blood sugar levels which prevents from developing diabetes.
It supports healthy growth and development by triggering the release of hormones that promotes the normal growth in children and teens.
Good sleep helps in weight management by regulating the hormones such as ghrelin and leptin which control appetite and improve insulin sensitivity.

Common Sleep Habits That Negatively Impact Mental Health

Irregular sleep schedule disturbs the circadian rhythm (body’s internal clock) of body which can lead to irritability and low energy levels.
Exposure to blue light before bed in the form of mobile phones, laptops or other devices leads to suppression of melatonin, a hormone that helps induce sleep.
Overthinking or rumination before sleep can lead to trouble sleeping which may worsen mental distress.
Having caffeinated drinks late in the day can interfere with sleep quality.
Both oversleeping and insufficient sleep can impact mental well-being.

How Sleep Impacts Mental Health?

The relationship between sleep and mental health is deeply interconnected. Mental health conditions can disturb sleep patterns and chronic sleep problems may increase the risk of developing psychological disorders or worsening the existing ones. Studies have shown that sleep disturbances are active contributors to the onset, course, and relapse of mental illness and not mere by-products of it.

Sleep deprivation is a primary driver of increased anxiety, aggression, depression and lower mood.
Among all the mental health conditions, depression has been shown to have most consistent relationship with sleep. Research has shown that those who experience persistent sleep problems are more likely to develop depression, bipolar disorder, and generalized anxiety disorder.
Children with Attention deficit hyperactivity disorder (ADHD) may experience difficulty falling sleep or staying awake. And it has also been seen those that disturbed sleep patterns may contribute to the development of symptoms that mimic those of ADHD.
Schizophrenia and insomnia frequently co-occur. Studies have reported that up to 80% of people with schizophrenia also report experiencing symptoms of insomnia.

Management

The management involves a multifaceted approach that includes both clinical and lifestyle interventions. Here are some key strategies:

Studies have shown that psychological treatments can be helpful for treating some sleep disorders. Cognitive behavioral therapy for insomnia (CBTI) has been strongly recommended by American College of Physicians as the first-line treatment for chronic insomnia.
Establishing a regular sleep schedule and avoiding the sleep habits that negatively impact mental health as mentioned already.
Melatonin- inducing medications can also be considered for complaints of insomnia.
Regular exercise and having a balanced diet can aid in better sleep.
Antidepressants used in dosages other than traditional depression treatment can be used for sleep disorders as they have sedating effects.
Bright light therapy can be used in patients with seasonal affective disorder. The light mimics the sun and is believed to regulate neurotransmitters and circadian rhythm, thereby reducing the feelings of depression.
Relaxation techniques such as progressive relaxation, which involves tensing the muscles, holding the tension briefly, and then releasing it. And music assisted relaxation involves listening to calming music to improve sleep quality in patients with various conditions.

Sleep is not merely a form of physical rest; it is vital for emotional regulation, cognitive functioning, and overall mental wellbeing. The disturbances in sleep not only affect physical health but can also lead to poor memory, cognition while increasing the risk for several mental health disorders. As rightly said, “a sound mind lives in a sound body”. when we get adequate quality sleep, we are able to function effectively not just physically but mentally and emotionally as well. Maintaining proper sleep schedule, engaging in regular physical activity, and having a balanced diet can improve sleep quality and psychological health. In severe cases where sleep deprivation contributes to serious mental health problems and impacts your daily life, seeking professional help becomes necessary to improve overall well-being and quality life.
