Digestion and gut: can constant overtime and lack of sleep disrupt the absorption of nutrients?

Chronic sleep deprivation and night work deal a blow not only to the nervous system, but also to the gut's ability to absorb vitamins and microelements. During the deep sleep phase, the human body triggers tissue regeneration processes, including the renewal of the mucous membrane cells of the small and large intestines.

If sleep is regular, short, or intermittent, the intestinal epithelial cells do not have time to fully recover. As a result, the barrier function of the gut suffers, and the villi responsible for absorbing nutrients from food begin to work less efficiently. A person may eat quality foods, but the body does not receive enough iron, magnesium, B vitamins, and other important elements.

The deficiency of these substances immediately affects cognitive abilities: concentration drops, memory worsens, irritability and rapid fatigue appear. A vicious circle is created, where the tired brain demands more energy, and the damaged gut cannot provide it with resources.

To restore normal nutrient absorption, it is necessary to normalize your rest schedule.
