Can Sleep Help Improve Depression?

Imagine a world where a simple night's rest could significantly alleviate symptoms of depression. But does sleep help depression? The relationship between sleep and depression is intricate, with evidence suggesting varying impacts. Individual factors like sleep quality, REM sleep, deep sleep, and underlying conditions such as sleep apnea significantly influence the effectiveness of sleep in managing depression.

Understanding Sleep and Depression

Sleep: Sleep is a complex biological process that involves a period of rest and unconsciousness that alternates with periods of wakefulness

Depression: Depression is a common mental health disorder characterised by persistent feelings of sadness, loss of interest, and a range of emotional and physical problems that can interfere with daily life.

Can Sleep Help Improve Depression?

Is sleep good for depression? Yes, as sleep deprivation often worsens depression, making it harder to manage emotions, and think clearly, and increasing the likelihood of mood swings. Sleep disturbances like insomnia or sleep apnea are frequently among the first signs of depression. Adequate and restorative rest, involving both REM sleep and deep sleep, is essential for managing depression because both sleep and depression affect the brain. This creates a strong interplay between the two, which can significantly impact one’s mental health.

Research Findings on How Sleep Helps Improve Depression

Research consistently supports the idea that better sleep can improve depression. 

Sleep duration: According to a study, the optimal sleep duration for reducing the risk of depression is 8 hours. Another study found that people who slept less than 7 hours per night had an 86% higher chance of developing depression. 

Sleep quality: A Johns Hopkins study found that people who had interrupted sleep had a 31% reduction in positive mood the next day. REM sleep is crucial for emotional processing, and the lack of it can make it harder to consolidate positive emotional experiences.

Sleep and emotional processing: The brain evaluates and remembers thoughts and memories during sleep. Lack of sleep can be especially harmful to consolidating positive emotional content. 

Sleep and emotional resilience: Poor sleep, including conditions like sleep apnea, weakens emotional resilience. Insomnia makes it more difficult to deal with daily challenges, further exacerbating depressive symptoms.

Sleep and treatment: There is evidence that sleep-related symptoms are important risk factors for depression and that interventions for insomnia may help treat depression. 

Some therapies can help people cope with depression and change their thought patterns around sleep. These include cognitive behavioural therapy (CBT), psychotherapy, and behavioural changes.

What’s the Success Rate of Sleep in Improving Depression?

Evidence shows that improving sleep can significantly help alleviate depression. For example, a 2022 study found that a single night of sleep deprivation improved mood in some patients with depression, though chronic sleep loss increases the risk of depression. Improving sleep quality, as found in a meta-analysis of 65 randomised controlled trials, led to notable improvements in depression, anxiety, and overall mental health. Achieving the right sleep duration, ideally 8 hours, has also been linked to a reduced risk of depression.
