On grandparents

Since taking care of grandchildren could be a highly demanding job that requires constant energy and time devotion, grandparental involvement in child raising could have a negative impact on grandparents' physical and emotional health. For example, taking care of grandchildren can reduce grandparents' own time for self-care such as missing their medical appointments. Therefore, they are likely to have a higher chance to suffer from physical health issues. In the US, compared with those who do not take care of their grandchildren, grandparents who are involved in childcare are more likely to have poor physical conditions, such as heart disease, hypertension or body pain. Besides physical health issues, grandparents are also likely to have emotional issues. To be more specific, raising young children again could be a stressful and overwhelming experience and thus results in different kinds of negative emotions such as anxiety or depression. In addition to physical and emotional issues, grandparents who are involved in caring for their grandchildren can also suffer socially. For instance, grandparents will be forced to limit their social activities so as to care for their grandchildren. By doing so, grandparents become more isolated from their social relations. Taking care of grandchildren also means more responsibilities, grandparents would fear for their grandchildren's future well-being because of their disability and death in the future. If grandparents cannot handle the caregiver role of their grandchildren well, this job can eventually become a burden or stressor and bring more severe physical health and emotional issues to grandparents.
