Endurance training makes natural killer cells more efficient and effective against inflammation Exercise not only trains our muscles and endurance – our immune system also becomes fitter, as a study has now confirmed. According to this study, regular jogging, cycling, and other endurance sports also "train" the natural killer cells of our immune system. In trained people, these white blood cells release more anti-inflammatory messengers, use cellular energy more efficiently,

The Immune System's David vs. Cancer's Goliath What looks here like an amoeba or a slug crawling along is a deadly enemy – a cancer cell. The much smaller, round immune cell seems powerless against it. But a new immunotherapy could help. It combines an antibody and an inhibitor in such a way that it mobilizes the T-cells of the immune system against cancer – and renders them immune to the cancer's counter-measures.

Late caffeine consumption keeps our brain awake even while we sleep A wake-up call even while we sleep: If we drink coffee late in the evening, it has consequences for our brain. A study shows that caffeine alters our sleep and keeps our brain more alert at night. This hinders the recovery of our brain and could also disrupt nighttime memory formation. Researchers found that this stimulating coffee effect is more pronounced in younger people than in older people. Caffeine aff

Clothes are often not hygienically clean with normal washing machines Nothing like clean: Despite supposedly hygienic wash programs, normal washing machines do not remove all germs, as a study shows. According to the study, bacteria often survive even 60-degree washes and settle in clothing and the machine, including pathogens and antibiotic-resistant germs. This could contribute to the spread of infections. This is particularly problematic when the work clothes of nurses, ca
