My girlfriend and I had a flu two months ago, when we moved to a new (and pretty cold and windy) city. We recovered normally with some paracetamol. Hers was much more mild, I had a cough for a few weeks.
Now, two months later, we went to an amusement park, getting totally exhausted and caught a lot of rain as well. I insisted in an open window at night, and then now she has flu symptoms again.
Is it normal to have a cold/flu twice in this two-month period? We are a 30y.o. couple, 3 years living together, with no prior conditions or diseases. I write because I am a bit hypochondriac and I would feel better with some feedback.
Vitamin D is now the most requested lab test over all other lab test. And for good reason (see list below!). I had this test done when i heard of the increased risk of cancer and found i had severe vitamin D deficiency. This explained why i had bronchitis (3 weeks), strep throat twice (1 month and over 2 weeks) and a cold (1 week) in less than 6 months. I had bone pain in my hand which i thought was arthritis but was due to vitamin D deficiency. Vitamin D council recommend 50 - 80ng/mL (125 - 200nmol/L) year round.
Excerpts from the article "How Vitamin D Protects You from the Flu and Other Infections"...
"A new study has confirmed that vitamin D plays an important role in activating your immune defenses against infectious diseases like the flu.
Vitamin D deficiency has already been linked to a wide spectrum of diseases including heart disease, cancer, diabetes, depression, autoimmune disease and many others.
The new study discovers that activation of T-cells to fight infections needs definite help from vitamin D. When a T cell recognizes foreign invaders like bacteria or viruses, it sends activating signals to the vitamin D receptor gene. The VDR gene then starts producing DVR protein, which binds vitamin D in the T cell. Then the vitamin D bound and activated DVR produces PLC-gamma1 protein — which allows the T cell to get started fighting the infection.
Dr. John Cannell has also reported that vitamin D helps produce antibacterial peptides that help protect against the flu. That is why in winter, when there is little sunshine, people are more prone to vitamin D deficiency and getting infected with flu viruses."
"Just take a look at this list of common chronic diseases that researchers have linked to vitamin D deficiency:
Moving to a new city is a stressful event that can dampen the immune system, making one more vulnerable to colds/flu. Taking good care of yourself along with Vitamin D (as Red_Star eloquently describes) and Vitamin C supplements should help your system recover.
