Hot weather naturally leaves many people feeling drained, but women in their 40s and 50s may be overlooking another possible cause. During perimenopause and menopause, changing hormone levels can trigger symptoms that closely resemble everyday summer exhaustion. Because these changes often develop gradually, many women dismiss them as part of the season instead of recognizing a hormonal transition. Medical experts say understanding the difference can help women seek appropriate care sooner rather than struggling through symptoms unnecessarily.
