As temperatures rise during summer, many people notice a significant drop in appetite. This change is largely due to the body's biological response to heat, where digestion, a thermogenic process, generates additional internal heat. Consequently, the hypothalamus signals a reduction in hunger to prevent overheating. Blood flow also shifts towards the skin to aid in cooling, leading to less blood reaching the digestive organs, which can slow digestion and make heavier meals feel unappealing. Hormonal changes, such as lower levels of ghrelin (the hunger hormone) and increased histamine, further suppress appetite. To counteract these effects, individuals are advised to consume smaller, more frequent meals, stay hydrated, and choose lighter foods that are easier to digest. Incorporating cooling herbs and avoiding heat-inducing foods can also help maintain energy levels and overall health during the summer months. By understanding these physiological changes and adjusting dietary habits accordingly, one can navigate the summer heat while ensuring adequate nutrition.
