People can't control the outside world, but they can control their reactions to it. A technique called cognitive restructuring can help a person change negative thinking and calm stressful reactions. It involves a four-step process, known as "stop, breathe, reflect, choose."

An estimated 3% of adults ages 65 and older currently have dementia, and that proportion rises substantially as people age. The most convincing evidence for reducing one's risk relates to the basic foundations for an overall healthy lifestyle: aerobic exercise, a plant-based diet, and quality sleep. Aerobic exercise helps reduce the buildup of toxic proteins in the brain and improves blood flow, a plant-based diet can manage inflammation, and quality sleep helps the brain clear out harmful proteins.

A 2023 study suggests that eating lots of ultra-processed foods, which are high in sugar, salt, fat, and additives, may raise the risk for depression.

A 2023 study suggests that people who average 10 or more hours sitting each day face higher risks of dementia than those who sit less, and those risks persist even if they exercise.

Rumination consists of a repetitive stream of negative thoughts or themes. It often involves mentally replaying a past scenario or conversation or trying to solve a vexing problem. But rumination can also damage mental and physical health, increasing the risk of depression, anxiety, insomnia, and inflammation. People can thwart rumination by finding distractions, changing location, relying on relaxation techniques, confiding in a friend, or taking action. Cognitive behavioral therapy can also help.

Seasonal affective disorder (SAD), a type of depression that begins in late fall and early winter, is caused by lack of sunlight exposure. Common symptoms of SAD include lack of sexual energy, overeating, problems sleeping, and social withdrawal. SAD is also associated with impaired cognitive function. Getting more sunlight from being outdoors or sitting in front of a sunlit window helps stimulate the brain's 24-hour sleep-wake clock. Taking antidepressants and using light therapy (which involves sitting in front of a light box) also can help manage SAD.

Semaglutide (Ozempic, Wegovy), which mimics a natural hormone called GLP-1, has become a popular obesity drug because it promotes dramatic weight loss. New evidence suggests this drug and others like it may also curb compulsions for things other than food. The drugs may also dampen cravings for alcohol, smoking, gambling, and excessive shopping by hampering activation of the brain's reward pathways. If further research confirms preliminary findings, the demand for GLP-1 drugs is likely to increase.

An estimated 58 million American adults live with a mental illness such as anxiety, depression, or bipolar disorder. More women than men receive treatment such as medication or counseling. But despite its pervasiveness, mental illness remains stigmatized. Scientific advances are helping dismantle damaging public attitudes about mental illness. People with mental health challenges can help combat stigma by embracing treatment, not taking other people's offhand comments personally, and sharing their personal stories.

People who are sedentary more than 10 hours per day may have a higher risk of later developing dementia than those who spend less time being inactive, according to a 2023 study.
