inflammation

A fever is not an illness but a weapon—your immune system's coordinated response to infection that raises your body's set-point temperature. When pathogens invade, immune cells release signaling molecules called pyrogens that travel to the brain and reset the temperature thermostat from 37°C to 39°C or higher. This increase is controlled and purposeful: the higher temperature slows bacterial growth, accelerates immune cell activity, and enhances antiviral proteins. Understanding fever as an adaptive defense explains why suppressing it indiscriminately can sometimes hinder recovery, yet also reveals when dangerous fevers require immediate treatment.

Obesity is a chronic disease shaped by hormones, brain, and environment. See how leptin, insulin resistance, and visceral fat drive metabolic syndrome.

Inflammation is the immune system's emergency response. When it becomes chronic, it is tied to heart disease, cancer, and neurodegeneration.
