Water, heat and intestines: why digestion can change in summer

Invisible summer stress for the body

Summer is traditionally associated with relaxation, plenty of fresh fruit and outdoor activities. However, at the same time, it is a period of the highest stress on our body due to the impact of high temperatures and changes in drinking habits. We often encounter unexpected disorders: sudden bloating (flatulence), a feeling of heaviness, diarrhea or, conversely, persistent constipation.

Traditionally, we tend to blame unwashed fruit or street food for this. However, modern 4P medicine and the science of the microbiome (which is now rightly called our "superorgan") prove that the real reason lies much deeper. Temperature stress and changes in water balance directly interfere with the work of trillions of bacteria that inhabit our gastrointestinal tract. Understanding how water and heat affect the microbiome allows us to avoid summer gastro-problems and maintain health with innovative solutions such as targeted pharmabiotics.

Physiology of heat: Why does digestion "shut down"?

To understand why your stomach hurts in the summer, it's worth looking at the evolutionary mechanisms of our body. High air temperature is perceived by the body as a powerful physical stressor, a reaction to which is triggered regardless of whether you're lying on the beach or running away from danger.

During stress, the body activates a rescue mechanism, suspending all long-term, energy-consuming projects for which "now is not the time" - and this primarily concerns digestion. To cool the body, the cardiovascular system redirects blood flow from internal organs to the skin (which is why we blush and sweat).

This leads to ischemia and hypoxia (oxygen starvation) of the intestine. The work of the gastrointestinal tract, the secretion of enzymes and motility are sharply slowed down. If food enters this "switched off" and blood-deprived intestine, it cannot be digested normally. Instead of assimilation, the processes of rotting and fermentation begin, which become ideal food for pathogenic microflora.

Water balance and the iced drinks trap

In the summer, we lose a huge amount of water through sweat. If the water balance is not replenished adequately, the body begins to "pull" water from wherever it can, and primarily from the large intestine. This leads to the compaction of feces and the development of persistent constipation. In addition, moisture deficiency destroys the protective layer of mucus (mucin) on the intestinal walls, which is a habitat for beneficial microbiota.

Trying to escape the heat, people make another common mistake - they drink ice water or very cold drinks with ice. Doctors and nutritionists emphasize that consuming too cold food or water is extremely harmful, as it causes a sharp spasm of smooth muscles, in particular the gallbladder and ducts. The spasm blocks the normal secretion of bile, which is necessary for the breakdown of fats and sanitation (disinfection) of the intestines from pathogens. The result is a stop in digestion, pain, heaviness and the reproduction of harmful bacteria. You need to drink a lot in the summer, but the water should be warm or at room temperature.

Dysbiosis: The effects of summer stress on the microbiome

Slowed motility, cold water cramps, and intestinal hypoxia lead to an imbalance in the microbiota (dysbiosis). Beneficial bacteria (commensals), lacking the right environment, die. Their place is immediately taken by opportunistic microorganisms that release toxins and gases (e.g., sulfides and methane).

This manifests itself in the form of acute flatulence, irritable bowel syndrome and even summer diarrhea. In addition, impaired barrier function leads to the fact that the toxins of pathogens penetrate the bloodstream, causing systemic chronic low-grade inflammation. Due to the close connection of the gut-brain axis, this inflammatory process affects the entire body: we feel exhausted, apathetic, and may also gain weight uncontrollably or be unable to lose weight.

Why do pharmacy multiprobiotics work "blindly"?

When summer diarrhea or bloating occurs, the traditional solution is to buy a regular mass-market probiotic. But advanced medicine warns against this step. Prescribing biological preparations with dozens of random strains of bacteria without taking into account the individual profile causes fierce competition in the intestines. Foreign microorganisms begin to conflict and can destroy the remnants of your own beneficial microflora, deepening dysbiosis and inflammation. In order to recover safely, purposeful action is required.

Targeted Correction: Pharmabiotic "My Second Brain. Gut Microbiome"

In order to help the intestines cope with the effects of summer heat, dehydration, or nutritional disruptions, Ukrainian scientists have developed an innovative new generation product – the niche pharmabiotic “ My Second Brain. Gut Microbiome ” .

This product is radically different from conventional supplements, as it is based on 37 years of scientific and clinical research. It is designed as a universal tool for rapid and deep restoration of the gastrointestinal ecosystem:

Elimination of flatulence (bloating): Special proprietary strains of lactobacilli aggressively suppress gas-forming flora that has multiplied due to hypoxia and spasms, quickly returning the feeling of a light stomach.
Fights constipation and diarrhea: The drug physiologically normalizes intestinal motility, helping with constipation (which occurs due to dehydration) or stopping traveler's diarrhea.
Relief of chronic inflammation: The bacteria in the preparation restore the protective layer of the mucous membrane and reduce systemic inflammation.
Metabolic regulation: The product is used to normalize weight (for weight gain or loss), as the restored microbiome dictates proper eating behavior and improves calorie metabolism.

The form of release of the drug is as convenient as possible for the summer season: it is 16 compact sachets (lyophilized powder) that do not spoil during transportation. It is enough to simply dissolve the contents in water or juice at room temperature.

Conclusions

Summer heat, changing drinking habits, and drinking iced drinks are serious stress for our intestines. These factors cause hypoxia of the digestive tract, stoppage of motility, and destruction of the beneficial microbiome, which inevitably leads to bloating, constipation, or diarrhea. Instead of swallowing random pills "blindly", it is worth applying a scientific approach. Proper hydration with warm water and the use of the niche pharmabiotic "My Second Brain. Intestinal Microbiome" allow you to purposefully and safely restore the internal ecosystem. A healthy microbiome is your reliable protection against inflammation and the key to lightness and energy throughout the summer.

Short questions and answers on the topic (Q&A)

1. Why does digestion often stop and cause heaviness in the stomach during intense summer heat?

Answer: High temperature is perceived by the body as physical stress. To cool the body, blood flows from the internal organs to the skin, causing hypoxia (oxygen starvation) of the intestines. In a state of stress, evolutionary mechanisms "turn off" digestion. Food that has entered the stomach is not digested, but begins to ferment, causing inflammation and the proliferation of pathogenic flora.

2. Why shouldn't you drink ice water in the summer and how does it affect the intestines?

Answer: Very cold water or drinks with ice cause a sharp spasm of the smooth muscles of the stomach and gallbladder. Due to the spasm, bile is not released in sufficient quantities, which blocks the breakdown of fats and allows pathogenic microorganisms to survive. This leads to acute flatulence (bloating) and constipation. Water to maintain water balance in the summer should be warm or at room temperature.

3. Why can regular probiotics from the pharmacy be harmful for summer bloating or diarrhea?

Answer: Mass-market probiotics often contain dozens of random strains of microorganisms that are prescribed “blindly.” Once in the gut, they begin to compete fiercely for resources and can aggressively suppress the remnants of your own, beneficial microflora. This only deepens the imbalance and inflammation.

4. What is "My Second Brain. The Gut Microbiome" and why is it perfect for summer?

Answer: This is an innovative niche pharmabiotic of the new generation (in the form of convenient 16 sachets), developed by Ukrainian scientists on the basis of clinical research. Its author's strains act purposefully: they are guaranteed to eliminate chronic inflammatory processes, fight acute flatulence (bloating), constipation (constipation) and diarrhea. In addition, it restores normal intestinal function, which helps to physiologically adjust weight (lose weight or gain weight).
