Energy Drinks, Pre-Workout And Caffeine: How Much Strains The Heart?
Caffeine can make people feel more awake and energetic.
It can also make the heart beat faster and raise blood pressure for a short time.
Most healthy adults can usually handle about 400 milligrams of caffeine in a whole day.
This amount includes caffeine from coffee, tea, soft drinks, energy drinks and supplements combined.
Energy drinks and pre-workout products can contain large amounts of caffeine and other stimulants.
Taking them before hard exercise may put extra stress on the heart.
Warning signs include a racing or irregular heartbeat, dizziness, anxiety or feeling faint.
Anyone with chest pain, fainting, severe breathing trouble or a constant abnormal heartbeat should seek medical attention.
People with heart problems should ask their doctor how much caffeine is safe for them.
Caffeine can temporarily raise heart rate and blood pressure by stimulating the nervous system.
Healthy adults generally tolerate up to about 400 milligrams of total caffeine daily, though individual limits vary.
Energy drinks and pre-workout supplements may contain concentrated caffeine and other stimulants that add cardiovascular stress during exercise.
Possible warning signs include palpitations, irregular heartbeats, anxiety, dizziness and unusually rapid heart rates.
People with heart conditions or those taking certain medications should consult a doctor and may need to consume less caffeine or avoid stimulants.
