Sleep is more than just a night routine, it’s an important part of our mental health. With changing lifestyles, people’s preferences have shifted, leading to sleep neglect and unnecessary stress and anxiety. Research indicates that 32.8% of adults experience insufficient sleep, meaning nearly a third of the adult population faces sleep deprivation. This lack of quality rest is closely linked to increased stress, anxiety, and other mental health concerns.

World Sleep Day is a reminder of how important sleep is for our health, mood, and overall well-being. This serves as an opportunity for all of us to inspect ourselves and know the value of sleep for better mental health.

Connection between Sleep and Mental Health

Sleep and mental health are deeply interconnected. A well-rested mind functions optimally allowing for better mental regulation, cognitive performance, and stress management. Here’s how it works:

1. Regulates emotion

During sleep, the brain processes emotions, helping to stabilise mood and maintain emotional balance. Poor sleep can make individuals more prone to irritability, mood swings, and stress.

2. Reduces stress & anxiety

Deep sleep lowers levels of cortisol, the stress hormone while boosting serotonin and dopamine which help in mood stablisation and make an individual feel happy.

3. Enhances cognitive function

A well-rested brain ensures better focus, memory retention, and effective decision-making. It prevents excessive stress, mental fatigue, or burnout.

4. Prevents mental health disorders

Better sleep reduces the risk of depression, anxiety, and even more severe conditions.

The better sleep you get, the more effective your mental health will be.

The Stress Anxiety—Sleep Loop

Stress and anxiety are the common disruptors of sleep. When the mind is overwhelmed, a vicious cycle of unnecessary thoughts emerges and sleep becomes one of the major issues. Understanding this loop is the first step towards freeing yourself.

This often begins with reflecting on the day’s conversations, worrying about tomorrow, and dwelling on uncertainties. Instead of being grateful for the day, we end up planning about the future. This triggers stress hormones making relaxation even more difficult.

Stress and anxiety spikes → Increased level of stress hormone → Poor quality sleep → Emotional instability & fatigue → More stress & anxiety

If the stress levels become more intense, it may lead to chronic sleep disorders such as:

Insomnia: Difficulty in sleeping due to an overactive mind.
Restless sleep: Frequent awakening during the night leads to fatigue.
Nightmares: Excessive anxiety may lead to stressful dreams.
