Did you know that sleeping after midnight can affect your mental health? A study from Imperial College London found that people who went to bed before 1am tended to have better mental health. Conversely, people who preferred to stay up after 1am had the poorest mental health.
The study involved 73,888 people, of whom 56% were women. The average age of participants was 63.5 years old, and they averaged seven hours of sleep per night.
Studies have shown that people who go to bed before 1 am generally report better mental health and lower rates of psychiatric, behavioral and neurodevelopmental disorders, depression and generalized anxiety disorder (GAD).
The importance of sleep to mental health
“Quality sleep is essential for our mental health. It helps the brain consolidate memories, process emotions, and maintain important cognitive functions like attention and decision-making,” says Dr Vipul Gupta, Head, Neurointerventional Surgery and Co-head, Stroke Unit, Artemis Hospitals, Gurugram.
He added, “While you sleep, your brain takes in the day’s information, consolidates what you’ve learned, and prepares you for the challenges of the next day. This overnight processing improves focus, increases your productivity, and increases mental clarity when you’re awake.”

Sleep and Mental Health
“Sleep is also crucial for regulating emotions. Getting enough sleep balances neurotransmitters such as serotonin and dopamine, which are important for maintaining a stable mood. Without enough sleep, your brain struggles to regulate your emotions, you become more emotionally sensitive, and it becomes harder to manage stress and maintain a stable mood. People who don’t consistently get enough sleep are more prone to mood disorders such as depression and anxiety,” says Dr Gupta.
Additionally, sleep is essential for emotional regulation: getting enough sleep helps maintain a balance of neurotransmitters like serotonin and dopamine, both of which are essential for mood stability.
“Lack of sleep inhibits the brain’s ability to manage emotions. This leads to heightened emotional reactivity and makes it difficult to cope with stress and regulate your mood effectively. People who consistently experience sleep deprivation are more prone to mood disorders such as depression and anxiety,” stressed Dr Gupta.
Effects on circadian rhythm
“Sleep is controlled by our circadian rhythm – our internal clock that regulates our sleep-wake cycles. When this rhythm is disrupted by staying up late at night, it can lead to irregular sleep patterns,” Dr Gupta said.
This disruption can interfere with the body’s natural processes, such as hormone production, metabolism and immune function, that contribute to overall health, including mental health.

Emotional and psychological effects
“Going to bed late can impair your emotional balance and mental resilience. Just like not getting enough sleep, staying up late can cause neurotransmitter imbalances, making you more emotionally sensitive and more susceptible to stress,” Dr Gupta added.
This can result in mood swings, irritability, and increased emotional reactivity. What’s more, lack of sleep due to staying up late can make mental illnesses like depression and anxiety worse and harder to manage.
Tips to improve your sleep and mental health
- Maintain a consistent sleep schedule: Try to wake up and go to bed at the same times every day, even on weekends.
- Create a relaxing pre-bedtime routine: Before bed, try to relax with calming activities like reading, listening to soft music, or practicing deep breathing or other relaxation techniques.
- Limit your screen exposure: Avoid looking at screens (cellphones, computers, TV) at least an hour before bedtime, as the blue light they emit can disrupt sleep.
- Maintain sleep hygiene: To promote restful sleep, keep your bedroom cool, dark and quiet.
- Monitor your caffeine and alcohol intake: Limit your caffeine intake and avoid alcohol close to bedtime, as these can reduce the quality of your sleep.
- Seek professional help: If you suffer from persistent sleep disorders or mental health issues, speak to a medical professional for personalized advice and treatment options.
