How sleep affects mental health – with 5 changes to make today

“Sleep is a key pillar in maintaining good mental health,” says Lisa Gunn, mental health prevention lead at Nuffield Health.

“Sleep is essential for maintaining good emotional and physical wellbeing due to it being so restorative. It helps us to function well in the every day, it benefits our mental processes such as memory and learning, and it also enhances our ability to cope with daily life stressors.”

Another expert describes sleep as a “basic human need” that is fundamental to living well.

“It has been scientifically proven that how well we sleep affects how we feel about our lives – whether that’s in terms of our mood or our relationships,” says Lisa Artis, deputy CEO of The Sleep Charity.

“Quality sleep helps to regulate our emotions and without that, our mental health is directly affected. When you are sleep deprived, your resilience and mood are lowered, and you also experience decreased energy levels. Sleep is vitally important for good physical, mental and emotional health.”

We all have occasional nights of poor sleep, often due to temporary lifestyle factors such as worrying about the day ahead, feeling ill or dealing with a long-term health condition.

The result can be feeling a little sluggish and not quite firing on all cylinders the next day. Yet even one night of disruption or sleeplessness can have a knock-on effect on your mental health.

“Just one bad night’s sleep can affect our mood, concentration and alertness,” explains Artis, “while long-term sleep deprivation has far more severe consequences. It’s been linked to several serious health problems such as heart disease, diabetes and stroke.

“There is also a circle of cause and effect with mental health conditions such as depression and sleep, as they can spur each other on,” she adds. “That’s why it’s important to break that insomnia cycle before there are serious physical and mental health consequences.”

When it comes to avoiding sleep issues to protect your mental health, prevention is key, according to both experts.

Artis and Gunn recommend introducing these five small but effective steps to create healthy habits that’ll help you sleep better.

“Try to wake up at a similar time and avoid lengthy lie-ins, as this will help to strengthen your body clock,” Artis advises. “Whenever possible, try and expose yourself to natural daylight in the morning, as this will help to suppress melatonin (the sleep hormone) and boost your alertness.”

Review your daily routine to see what could be affecting your sleep. “For instance, if you are sensitive to caffeine, try to avoid it eight hours before bed,” says Artis. “This will help to stop caffeine interfering with your ability to get to sleep and stay asleep.”

“Exercise is great for both your sleep and your mental health, but try to be active earlier in the day rather than just before bedtime,” Artis advises.

“You will sleep a lot better if your bedroom is cool, quiet, dark, clutter-free and you have a comfortable bed to get into,” according to Artis.

Once in bed, avoid watching TV or scrolling through your phone, as these activities won’t help with winding down.

Think bath, book, and bed, Gunn advises. “The bath doesn’t have to be an actual bath,” she explains. “It can be anything that helps your body relax.”

She adds: “The book can be any activity that starts to unwind your mind. Lastly, keep sleep as the main association you have with your bed.”
