How to improve mental health: 5 proven ways

Expert tips, articles, and podcasts about how to improve mental health, all in one place.

At Heights, we talk a lot about brain health. It’s kind of our thing. But among all that discussion, it’s important to not forget about mental health. Brain health is about optimising the efficiency and performance of your brain, mental health considers your mind, how happy you are, and how you think.

In this article, we've gathered some tips on how to improve mental health from leading experts.

How to improve mental health

Every week, the Heights team invites the world's leading scientists and experts on brain health, wellness, and psychology onto our Braincare podcast. In a recent episode , we chatted with neuropsychologist Nawal Mustafa, M.A. about how to improve mental health.

You might recognise Mustafa from her popular Instagram account @thebraincoach , where the Canadian-Pakistani scientist raises awareness about the importance of mental health to her nearly 600,000 followers. Here are some of Nawal's good mental health tips.

What are 5 ways to improve mental health?

1. Seek social connection

Social isolation is a worldwide epidemic and a recent study published in the International Psychogeriatrics shows that our loneliness problem was considerably exacerbated by the COVID-19 pandemic.

Yet social connection is a core psychological need for us as a species, and lack of it is associated with deteriorating mental health. “Connection is very, very important… and research shows it helps with our mental wellness ,” says Mustafa.

She admits that it’s been tough for people to stay connected with others during the pandemic, but she encourages everyone to get creative:

  • If you live in an area where there are still restrictions on events and gatherings, you can still go beyond phone calls and try virtual game nights or remotely watching a movie or TV show together

  • Send an old-fashioned written letter or postcard.

  • Fire off a text, even if it’s a simple, “I’m thinking of you right now.”

2. Get more sleep

Just one night of poor sleep can sabotage your mental health and lead to moodiness and irritability, warns the NHS , and several nights of short sleep can cause long-term mood disorders.

Mustafa agrees. “Sleep is important for a number of reasons, especially when it comes to our brain function,” she explains. “It allows our nerve cells to communicate with each other. It [also] plays a… housekeeping role for us, so it removes toxins in our brain and allows us to… recuperate overnight.”

Both the NHS and Mustafa suggest striving for approximately eight hours of shut-eye a night is one way how to improve mental health. If you have trouble sleeping, try:

  • Keeping your room cool and dark.

  • Lowering the temperature.

  • Running a sound machine or a fan, or wearing earplugs.

  • Keeping bright lights, including the light from your smartphone, out of the bedroom in the evening.

3. Eat a healthy diet

At Heights, we’ve seen the significant impact that nutrition has on the brain.

“Our brain functions best when it gets nutrient-dense foods, so eating high-quality foods that contain a lot of vitamins, minerals, [and] antioxidants… nourish the brain… and protect from oxidative stress,” says Mustafa.

Mustafa recommends the Mediterranean diet for optimal braincare (or the MIND Diet), but a study at Heights found that many of our everyday diets don’t meet the nutritional needs of our brains.

4. Move your body

“Another thing that helps improve mental wellness is exercise,” says Mustafa. For example, one study found that regular physical activity had significant antidepressant effects on the brain.

“Exercise is something that stimulates the brain’s plasticity ,” says Mustafa. “It allows us to grow new connections between cells. It's really important for the cortical areas of our brain. Also, it boosts your mood.”

The mental health-enhancing effects of exercise happen quickly. In fact, the American Psychological Association reports that many people feel happier and more balanced within just five minutes of working out.

5. Get more sunshine

“[Sunshine exposure is] definitely also very helpful in our mental well-being,” explains Mustafa. “Sunlight triggers the release of serotonin in the brain. And this is a hormone that's associated with boosting mood and helping a person feel calm and focused. Without enough sun exposure, serotonin levels can dip. And if that happens, you might notice a significant change in your mood.”

Sunlight also carries additional mental health benefits. For example, your body converts the sun’s ultraviolet rays into vitamin D, and higher vitamin D levels are associated with mental well-being . The sun also helps regulate your sleep-wake cycle, potentially enhancing your sleep quality and sleep duration over time (boosting your mental health even further).

How can I improve mental health naturally?

To summarise, Mustafa recommends that we:

  • Invest in our social connections and relationships

  • Get more sleep

  • Eat a healthy diet

  • Exercise regularly

  • Enjoy the sunshine
