Ruokahalvaus

Ruokahalvaus, also known as food paralysis or food coma, is a temporary state of lethargy and drowsiness that some individuals experience after consuming a large meal. This phenomenon is not a true medical paralysis but rather a subjective feeling of reduced energy and a desire to rest.

The exact physiological mechanisms behind ruokahalvaus are not fully understood, but several factors are believed to contribute. One prominent theory involves the digestive process itself. After eating, the body diverts a significant amount of blood flow to the digestive system to aid in nutrient absorption. This increased blood flow to the gut might lead to a temporary reduction in blood flow to the brain, potentially causing feelings of fatigue.

Another contributing factor could be the type of food consumed. Meals high in carbohydrates, particularly refined carbohydrates, can lead to a rapid rise in blood sugar levels, followed by a subsequent drop. This fluctuation in blood glucose may contribute to feelings of tiredness. Similarly, meals rich in tryptophan, an amino acid found in foods like turkey and dairy, can be converted to serotonin in the brain, a neurotransmitter associated with mood and sleepiness.

The size of the meal also plays a role. Consuming very large quantities of food requires more energy for digestion, potentially exacerbating the feeling of lethargy. While ruokahalvaus is generally considered a normal physiological response and not a cause for medical concern, persistent or severe fatigue after meals could warrant a discussion with a healthcare professional to rule out any underlying medical conditions.
