Excessive heat during summer can affect hormone levels, as high temperatures place additional stress on the body. Experts explain that heat can lead to dehydration, which can interfere with the body’s hormonal balance, particularly affecting the adrenal glands, which regulate stress hormones like cortisol. Increased cortisol levels due to stress and dehydration can cause fatigue, mood swings, and irritability. For women, high heat can also impact estrogen and progesterone levels, potentially causing irregular menstrual cycles or discomfort during periods. Additionally, heat can disrupt thyroid function, leading to imbalances in metabolism. Staying hydrated, avoiding extreme heat, and managing stress can help mitigate these effects.
