The change of seasons can be a real "earthquake" for our body!

In reality, the reasons for which our organisms go into crisis mode at the change of season are not completely known yet. Some studies suggest that climatic variations of temperature, humidity and pressure could influence some chemicals (neurotransmitters) involved in the biological sphere. Furthermore, when the two critical seasons, summer and winter, approach, our body prepares for the net change (hot or cold)

Lastly, never underestimate the change of time during daylight saving and the effect that it has on tricking the body into experiencing more hours of light. The change of season brings about a series of symptoms for the body that includes fatigue, weakness, anxiety, insomnia, irritability, drowsiness, gastric disturbances and general malaise.

All of these symptoms are alarm bells to a non-performing physical and mental state. Your intestines feel "unprepared" and taken by surprise by these sudden changes to daily life. According to various scientific communities, this experience is defined as “intestinal dysbiosis" (imbalance of the normal intestinal bacterial flora).

Let’s take a look at the common bodily symptoms during a change of season:

Being anxious and irritable

Both are linked to the activity of serotonin, a neurotransmitter that regulates mood. Neurotransmitters are thought to be in poor concentration in the case of dysbiosis.


It is caused by a low production of melatonin, the precursor of which is serotonin. Both of these are directly affected by the change in seasons.

Gastric discomforts

These are common, and they are probably the consequence of forced adaptation to new climatic conditions. Often triggered by the change of seasons which can stimulate important nerve and hormonal pathways, they promote an excess of acid excretion in the stomach exacerbated by a dysbiotic intestine, therefore poor immune response and explosion of all the symptoms listed above.

How to remedy the symptoms of a change in season

There is no real ‘quick fix’ that can prevent the change of seasons from affecting your immune system in one way or another. Self-aware individuals prepare for this change in seasons by taking precautionary measures to delay or prevent the onset of most symptoms. This include adding a probiotic supplement into their daily routine, beginning at least three weeks prior to the seasonal shift.

In addition to a daily probiotic, there are a few personal activities an individual can adopt in order to further delay or prevent any bodily effects due to a change in season. They include:

Proper nutrition

Researching and incorporating a proper nutritional diet into your daily life

Being active

Using physical activity to defeat fatigue and stress

Quality sleep

Aiming for at least 8 hours of sleep per night
