Feeling jittery? Before you order your next pumpkin spice latte, consider how much caffeine you're consuming. While caffeine has its perks, boosting alertness and concentration, too much can cause stomach upset, insomnia, anxiety, muscle tremors and rapid heartbeat, reports MedlinePlus. Caffeine isn’t limited to drinks, either — it shows up in everything from ice cream to headache medicine.
If you’re a healthy adult without caffeine sensitivities, the Harvard School of Public Health recommends limiting your intake to 400 mg per day.
