Avoiding coming into contact with others is difficult - public transport, school, work, crowds. Probably the best thing you can do is get a flu shot - got one myself last week. 20 euro, 10 mins, local pharmacy.

So how does the cold affect our "stock" of immune cells? It appears to increase them, at least certain types of immune cells. Longterm coldwater immersion (3 times a week for 6 weeks) in healthy males was shown to increase lymphocyte numbers. This is in line with the fact that habitual winter swimmers have higher numbers of white blood cells compared to nonhabitual winter swimmers. Additionally, another study demonstrated that cold exposure in a climatic chamber at 41°F (5°C) increased white blood cell numbers including cytotoxic T lymphocytes, which are a specialized type of immune cell that kills cancer cells. Males exposed to a cold (4°C) room for 30 minutes decreases their core body temperature by around 0.45°C and increased natural killer T cell number and activity. Natural T killer cells are another a type of immune cell that kill viruses and tumor cells. All of this may serve to bolster the anecdote shared often among communities of winter swimmers, which is that they experience fewer everyday cold and flu symptoms. In fact, an association has been demonstrated in epidemiological studies between winter swimming and a 40% decreased incidence of respiratory tract infections . More work needs to be done to better understand what the longterm effects of chronic cold exposure are on immune cell numbers and functions to state definitively what this all means, though.

I would personally take cold showers every day, I never take a hot shower. cold showers are also non existent in Ireland from May to October even but in the colder Dec to March or April even, they're let's say, challenging!! the other half thinks its madness but you get used to it after a while. during storm emma I kept it up as well…:eek tough but I felt amazing after which is generally what I feel every time I have one. it could even just be a psychological thing but feck it, it's good for you I think.

People take a pill every day, they get sick anyway, and then tell themselves that they would have been sicker without the pill, or sick more often. People take a pill when they get sick, get better a few days later, and tell themselves that taking the pill sped up their recovery. People like to feel in control of their health. It's the basis of the placebo effect.
