When it comes to natural immunity, have you ever wondered why many people feel healthier overall in summer or why their natural immunity seems to wane in winter?
Much has been said about immunity since we dealt with the pandemic – immune systems and their differences have influenced how some people exposed to COVID-19 get the disease with acute symptoms while others with strong natural immunity do not even knew they had it.
But there is something else that goes on with our bodies even when a global pandemic isn’t afoot – seasonal immunity. Have you ever wondered why people with arthritis seem to have it worse in the winter when it is cold? Or why do many people feel healthier overall in summer or why their natural immunity seems to wane in winter?
“Summer immunity is our tendency to be healthier during the summer season,” said Elliot Reimers, NASM Certified Nutrition Coach, MS (C), CISSN, CNC, in Eugene, Oregon. “That’s because more fruits and vegetables are available and we are eating more of them. By eating nutrient dense foods, it’s easier, really [get] Recommended daily amounts of vitamins and minerals. Summer is also when we are more active and get a lot of exercise. “
However, in spring and summer, some people react acutely to pollen – from sneezing and watery eyes to headaches and sore throats. This happens because the immune system recognizes the pollen as a threat and works at full speed to counter it. Our immune system releases histamine and that is what causes all of these reactions.
Differences in Natural Immunity
Why do some people struggle with allergies in spring and summer while others don’t sniff? “Everyone’s immunity is different,” says Reimers. “It can also come with age. Adults tend to have stronger immunity, but the elderly may have weaker immune responses. Respiratory illnesses, migraines and autoimmune diseases are some of the conditions that worsen in summer and are made worse by rising temperatures. “
In 2015, a group of researchers from the University of Cambridge published results from a study they conducted to determine how genes can also play a role in seasonal well-being and summer immunity. Through the study “Widespread seasonal gene expression shows annual differences in human immunity and physiology” they wanted to learn more about the following:
“Various biological processes show seasonal fluctuations in humans, including those with important immunological functions, such as vitamin D metabolism. The loss of skin pigmentation as people migrated from Africa to more temperate and colder zones to increase sunlight-driven vitamin D production is an important example of human evolutionary adaptation to different environments. However, it is unknown how seasons of the year could affect the underlying molecular details of human physiology in a broader sense. In this context, we hypothesized that the anti-inflammatory circadian transcription factor ARNTL (BMAL1) would show seasonal gene expression differences, since daylight carries circadian rhythms in mammals. Tissue-specific molecular clocks control a wide variety of cellular processes and influence the immune response. “
Genetics and immunity
Regarding the immune system, they discovered: “Amazingly, we found that ∼ 23% of the genome (5,136 unique genes out of 22,822 genes tested) had significant seasonal differences in expression in the BABYDIET dataset. Among the seasonal genes, two different antiphasic patterns of gene expression were evident: 2,311 genes (2,922 unique probes) had increased expression in summer (defined as June, July and August, mean change = 1.2572), while 2,826 genes (3,436.) Unique probes ) were upregulated in winter (defined as December, January, February, mean change in folding = 1.3150), which shows that different transcription landscapes are present in the peripheral immune system at different times of the year. “
Chiropractic To Boost Immunity
Reimers adds, “Chiropractic adjustments can help improve blood flow and relieve the body of pain and stress, which boosts the immune system.”
“Chiropractic is much more than just relieving and treating neck and back pain,” added David Tannenbaum, DC, of Tannenbaum Chiropractic in Beverly Hills, California, adding to System. With the improved function and mobility of your spine and your body, you can even strengthen your immune system … Your immune system can suffer from this compression of the nerve tracts, which weakens your body’s natural defense mechanisms against disease. As a result, studies have shown that chiropractic care for relieving stress, pain, and misalignment of the spine improves nerve function and can potentially boost your immune system by 200%.
