Chronobiology and not so much on biotype. These topics are covered in our professional training course taken by health professionals. There are not many details I can reveal without violating intellectual property rights, but here’s what I can explain about the trends we have for immune drops at certain times of year and influence your vacation recommendation and time of lowered immunity.
Though many people think about the immune system being weaker in the winter because we’re prone to getting flus, ph360 delves much deeper than that. We acknowledge that there are inherent differences in people’s immune systems (much like what’s revealed in this study:
and the endogenous/exogenous factors that may influence them (see https://www.sciencedirect.com/science/article/pii/S036981140700274X).
I’m not privy to reveal everything we’ve found, but the month of birth is related to the immune system in many ways. For just a few examples, see:

We also have a separate risk factor for immune issues that considers things like seasons (see https://www.nature.com/articles/ncomms8000), age (see https://www.ncbi.nlm.nih.gov/pubmed/26702035/ ) gender (see https://www.ncbi.nlm.nih.gov/pubmed/15485092/) and a few other variables.
