What is one effect of dehydration on the body?

Dehydration significantly affects the body's ability to regulate temperature. When the body does not have enough fluids, it struggles to maintain a stable internal temperature, which can lead to overheating. This is particularly evident during physical exertion or in hot environments, where the body relies on sweat to cool down. If dehydration occurs, the process of sweat production is impaired, making it difficult for the body to lose heat effectively. Therefore, the reduced ability to regulate temperature is a critical consequence of dehydration and poses health risks, especially in vulnerable populations such as the elderly or those engaged in intense physical activities.
