Complete a follow-up response to this student's post. One thing that really surprised me was learning that anticholinergic drugs can cause hyperthermia by reducing the body's ability to sweat. I always thought of the common side effects like dry mouth, blurred vision, constipation, and urinary retention, but I didn't realize how serious the risk of overheating could be, especially in older adults or during hot weather. Since these drugs block the muscarinic receptors involved in sweat gland activity, the body can't cool itself down through sweating
