Did you know going to sleep post-midnight can affect your mental health? According to a study by the Imperial College, London, it was found that people who slept before 1 am tended to exhibit healthier mental profiles. Conversely, those who preferred staying awake until 1 am or later showed the poorest mental health outcomes.
The study included 73,888 participants, with females comprising 56% of the cohort. The average age of the participants was 63.5 years, and they typically slept seven hours per night, on average.
According to the study, individuals who go to bed before 1 am generally exhibit better mental health, reporting lower incidences of mental, behavioural, and neurodevelopmental disorders, as well as depression and Generalised Anxiety Disorder (GAD).
Importance Of Sleep For Mental Health
“Getting quality sleep is essential for our mental well-being. It helps our brain consolidate memories, process emotions, and maintain important cognitive functions like attention and decision-making,” said Dr Vipul Gupta, Chief – NeuroInterventional Surgery; Co-Chief Stroke Unit, Artemis Hospital, Gurugram.
He added, “During sleep, our brain takes in the information from the day, solidifies what we've learned, and gets us ready for the next day’s challenges. This overnight processing improves our concentration, boosts productivity, and enhances mental clarity when we're awake.”

Sleep And Emotional Health
“Sleep is also incredibly important for keeping our emotions in check. When we get enough sleep, it helps balance neurotransmitters like serotonin and dopamine, which are key to maintaining a stable mood. Without sufficient sleep, our brain struggles to regulate emotions, leading to increased emotional sensitivity and making it harder to manage stress and maintain a steady mood. People who consistently don’t get enough sleep are more prone to mood disorders like depression and anxiety”, said Dr Gupta.
Furthermore, sleep is crucial for emotional regulation. Adequate sleep helps to balance neurotransmitters like serotonin and dopamine, which are essential for mood stability.
“Lack of sleep disrupts the brain's ability to manage emotions. This can lead to heightened emotional reactivity, making it harder to cope with stress and regulate mood effectively. People who consistently experience poor sleep are more vulnerable to mood disorders, such as depression and anxiety,” highlighted Dr Gupta.
Impact on Circadian Rhythms
“Sleep is governed by our circadian rhythms, which are internal biological clocks that regulate sleep-wake cycles. When we disrupt these rhythms by consistently staying awake late into the night, it can lead to irregular sleep patterns,” said Dr Gupta.
This disruption can interfere with the body's natural processes, including hormone production, metabolism, and immune function, all of which contribute to overall health, including mental health.

Emotional and Psychological Impact
“Going to bed late can mess with your emotional balance and mental resilience. Just like not getting enough sleep, staying up late throws off the balance of neurotransmitters, making you more emotionally sensitive and stressed,” added Dr Gupta.
This can cause mood swings, irritability, and increased emotional reactions. Additionally, insufficient sleep from staying up late can aggravate mental health conditions like depression and anxiety, making them more difficult to manage.
Tips for Improving Sleep and Mental Health
- Maintain a Consistent Sleep Schedule: Even on weekends, try to wake up and go to bed at the same time every day.
- Create a Relaxing Bedtime Routine: Wind down before bed with calming activities, such as reading, listening to soft music, or practising relaxation techniques like deep breathing.
- Limit Exposure to Screens: Avoid screens (phones, computers, TVs) at least an hour before bedtime as the blue light emitted can interfere with sleep.
- Maintain Sleep Hygiene: Make sure your bedroom is cool, dark, and quiet to encourage restful sleep.
- Monitor Caffeine and Alcohol Intake: Limit caffeine and avoid alcohol close to bedtime, as these can disrupt sleep quality.
- Seek Professional Help: If you struggle with persistent sleep problems or mental health issues, consult a healthcare professional for personalised advice and treatment options.
