In recent years, winter health trends have caused a real stir among Ukrainians: cold baths, kombucha, various dietary supplements and trendy nasal sprays. People seek to strengthen their immunity and protect themselves from viral infections, but experts warn that not all methods really work.
Immunologist Professor Eleanor Riley explains that swimming in cold water gives a quick burst of energy thanks to adrenaline and endorphins, but it does not strengthen the immune system. White blood cells may appear more temporarily, but after a few hours their level returns to normal. Professor John Tregoning adds that the feeling of health after winter procedures is mainly associated with reduced stress, rather than an increase in the body's defenses.
Family doctor Margaret McCartney advises paying more attention to moderate physical activity, which really reduces the risk of viral infections. The same applies to spending time in nature and an active lifestyle, dancing, singing or jogging.
Popular drinks like kombucha and various dietary supplements are often touted as ways to boost immunity. However, there is little scientific evidence to support their effectiveness. Vitamin C and multivitamins also have little effect on protecting against colds, while vitamin D has shown some benefit for those with vitamin D deficiency and respiratory illnesses.
Doctors call vaccination the only proven way to strengthen immunity. The flu vaccine begins to work 7–10 days after administration and really helps reduce the risk of the disease. It is also important to follow a healthy lifestyle: do not smoke, maintain a normal weight, get enough sleep, wash your hands regularly, and stay in well-ventilated areas.
In general, experts advise not to look for "magic bullets" but to take care of your overall health and reduce stress - this is much more effective than trendy winter methods.
