Hormone regulation refers to the body’s ability to produce, release, balance, and adjust hormones so they can effectively control many essential processes. Hormones are chemical messengers that travel through the bloodstream and signal organs and tissues to perform specific functions.

Split ends are a common hair condition where the tip of a hair strand frays or separates into multiple parts. This happens when the protective outer layer of the hair (the cuticle) becomes worn down, allowing the inner structure of the hair to split.

Split ends are also known by the technical term trichoptilosis. They are not a disease or medical condition, but rather a structural change in the hair fiber that affects appearance, texture, and manageability.

Anhedonia is a term used to describe a reduced ability to feel pleasure or enjoyment from activities that are typically found rewarding. This can include hobbies, social interactions, food, achievements, or other everyday experiences that once felt satisfying or meaningful.

Anhedonia is considered a symptom or experience, not a standalone diagnosis.

Non-communicable diseases (NCDs) are health conditions that are not spread from person to person. Unlike infectious diseases, they do not result from bacteria, viruses, or parasites and cannot be transmitted through contact, air, food, or water.

These conditions are typically long-lasting and often develop gradually over time. Because of this, they are sometimes referred to as chronic diseases, although not all chronic conditions fall into this category.

Understanding what non-communicable diseases are can help clarify how they differ from contagious illnesses and why they are such a major focus in global health discussions.
