Winter Sickness Explained by Andrew Huberman


As the winter chill sets in, so does the onslaught of sniffles and coughs. But why does the cold season bring a spike in sickness? Dive into our latest blog where we unravel the science behind the winter illness wave, guided by Professor Andrew D. Huberman’s expertise. Learn how the shorter days, colder weather, and our own cozy indoor gatherings make us easy targets for colds and flu. Don’t let the winter blues catch you off-guard—stay ahead by understanding the secrets of seasonal sickness!

Winter months & sickness

The correlation between winter months and an increase in colds and flus has been well-documented by scientific research. Professor Andrew D. Huberman explains that this phenomenon can be linked to a combination of factors, including shorter days leading to longer nights, colder temperatures, and people spending more time indoors. This indoor time increases close proximity amongst individuals, which, in turn, heightens the risk of transmissible illnesses such as colds and flus. Further contributing to this trend are behavioral patterns observed during the cold months. Research demonstrates a direct relationship between physical distance and the transmission of these illnesses. For example, studies have shown that there are higher chances of contracting a cold or flu from someone who is sneezing or coughing if you are physically close to them. The likelihood of transmission escalates with decreased distance, making public transport, classrooms, and shared living spaces potential hotspots for spreading these viruses. Moreover, transmission is not limited to exposure to respiratory droplets from sneezing or coughing. Viruses can also spread through physical contact, such as handshakes, or by touching surfaces where the virus is present due to inadequate hand hygiene following nose wiping or tissue use. Professor Huberman’s insights not only highlight the biological factors at play but also the behavior-driven risks contributing to the increased prevalence of colds and flus in the winter months. Understanding these dynamics can help individuals adopt better hygiene practices and awareness about physical proximity during times when such illnesses are more prevalent.


As winter wraps us in its chilly embrace, remember that staying healthy is more than just bundling up. Close quarters and increased indoor activity can heighten the risk of cold and flu transmission. Be mindful of your environment and interactions—practice good hygiene and consider keeping a little extra space when possible. By understanding the factors that contribute to seasonal sickness, we can take steps to protect ourselves and keep our communities healthier, even through the coldest months. Stay vigilant and stay well!
