    High temperatures, exercise, and medications.

    Explanation:

    Beta blockers can cause a decrease in heart rate while thyroid medications may increase it. Heat can increase your heart rate because your heart plays a big role in keeping you cool. A workload of exercise can also increase the demands on your cardiovascular system, which increases your HR.
