What is a common sign of approaching death?

Cyanosis is a common sign of approaching death and indicates a lack of oxygen in the body. This manifests as a bluish coloration of the skin, particularly in areas with less blood flow such as the lips, fingertips, and toenails. As the body begins to shut down, circulation decreases, leading to this characteristic symptom.

In the context of terminal illness or death, other signs often include changes in breathing patterns, decreased appetite, and withdrawal from social interactions, as the body prepares for the end of life. Recognizing cyanosis can be crucial for caregivers and healthcare providers as it helps in understanding the patient's status and preparing for the final stages of life.

The other options reflect behaviors or conditions that are typically not associated with approaching death. Increased social interaction, heightened sensory perception, and improved communication may indicate the opposite—an individual who is functioning well or recovering, rather than nearing the end of life.
