People who age at home may feel lonely, harming their health. Research shows that lonely people are at a higher risk for heart disease, depression, and dementia. Talking to and spending time with people lowers stress and stimulates the brain. Those who age at home are also at risk of injury. They could hurt themselves from doing yard work or slipping in the bathroom. People aging at home also miss the recreation that retirement homes offer. For example, missing out on aerobic classes meant for older adults may make it more difficult to meet exercise goals.
