A moderate and short-term stress response can benefit the immune system, while a severe and long-term stress response can be detrimental to the immune system. The balance between the positive and negative effects of stress hormones is essential for maintaining the health and well-being of the organism. [12] [13] [14] [4]
2024 was packed with health care innovations, from a new blood test detecting Alzheimer’s disease to deep brain stimulation reversing paralysis. Heading into the New Year, medical experts are ...
The name multiple chemical sensitivity has been criticized, partly because MCS is not a sensitivity in the allergic or immunological meaning of that word. [5] Being more sensitive than average to some chemical exposures (e.g., secondhand smoke) is fairly common. [5] MCS is generally used to refer to more significant disability. [5]
