The science behind reduced appetite in summer heat: how the body prioritizes cooling over digestion
By
Dan Baumgardt
Summary
This article explains the physiological reasons why appetite decreases during hot summer weather. It describes how the body works to maintain a stable internal temperature of 37°C, and how eating — especially hot or heavy meals — generates additional metabolic heat that the body must work to dissipate. The body prioritizes cooling mechanisms (like sweating and increased blood flow to the skin) over digestion, leading to reduced hunger signals. The article covers the role of the hypothalamus in regulating both temperature and appetite, and explains why lighter, cooler foods become more appealing in the heat.
