Physical activity
Physical activity has been linked to wellbeing in numerous ways. Negative emotions are associated with an increased risk of physical disease and poor health habits, and people with mental illness are more likely to be physically inactive.
​
There are obvious physical benefits to being active, but increasing movement or activity also decreases symptoms of depression, anxiety, and loneliness and improves mental focus and clarity.
​Nutrition
Poor nutrition leads to physical health problems such as obesity, diabetes, heart disease, and even cancer, but there is significant research demonstrating a relationship between diet and mental health.
​
Eating a balanced diet rich in nutrients (and limiting processed or sugary foods) has been associated with wellbeing. A review of research on children and adolescents found that a poor diet was linked to poorer mental health.
​
Sleep
Neuroimaging and neurochemistry research suggests that good sleep hygiene fosters mental and emotional resilience, and sleep deprivation leads to negative thinking and emotional vulnerability.
Further, sleep problems are more likely to affect people with psychiatric disorders and may increase the risk of developing mental illness.
Particularly, insomnia increases the risk of developing depression.
​
Getting seven to nine hours of quality sleep during the same hours every night is recommended. Lifestyle changes such as avoiding caffeine, nicotine, and alcohol; getting physical activity; decreasing screen time; and using the bedroom only for sleep and sex can improve sleep quality.
Relaxation techniques and cognitive behavioral techniques to reduce stress and anxiety can also be effective ways to improve sleep and overall wellbeing.
