How Much Caffeine is too Much?
Blog
Whether it’s coffee to start the day, a cold soda to revive the afternoon, or a beloved pumpkin spice latte to embrace the season, caffeine is a popular pick-me-up for many. However, while these caffeinated drinks can provide a much-needed boost, excessive consumption can have negative effects on your health. In rare instances, it can even be fatal. That’s why it’s important to know the facts.
What is caffeine?
Caffeine is a naturally occurring stimulant that affects your central nervous system, helping you feel more awake and alert. It’s found in coffee beans, tea leaves, kola nuts, yerba mate, guarana berry, and cacao beans.
Safe limit for caffeine: How much is too much?
According to the U.S. Food and Drug Administration, most healthy adults can consume 400 milligrams of caffeine a day without any dangerous or negative health effects. If you are pregnant, the American College of Obstetricians and Gynecologists suggests keeping your caffeine intake below 200 milligrams a day.
The amount of caffeine in beverages can vary greatly, making it easy to consume too much caffeine. Here are some typical caffeine ranges for beverages:
An 8-ounce cup of coffee has between 80 to 100 milligrams of caffeine.
An 8-ounce cup of green or black tea has between 30 to 50 milligrams.
A 12-ounce/regular-size can of caffeinated soda has between 30 to 46 milligrams.
An 8-ounce energy drink has between 40 to 300 milligrams. Many energy drinks only come in 12-ounce or 16-ounce cans that can contain up to 400 milligrams of caffeine—the safe daily limit.
When adding up your caffeine intake for the day, make sure you include all caffeine sources. Caffeine can also be found in chocolate and baked goods, like cookies. It’s even in some medications, such as those for headaches. And decaffeinated coffees and teas may still contain between two to 15 milligrams of caffeine. Whenever possible, read all package labels to see how much caffeine a product contains.
Side effects of too much caffeine
Side effects that you have had too much caffeine include:
Agitation or irritability.
Fast heart rate.
Feeling anxious or restless.
Increased urination, which can lead to dehydration.
Insomnia or trouble falling asleep or staying asleep.
Muscle twitches, such as eye twitches.
Nausea or upset stomach.
Can you overdose on caffeine?
Consuming around 1,200 mg of caffeine at one time can cause toxic effects on your health, according to the FDA.
While rare, it is possible to overdose on caffeine, which can lead to death. Severe side effects of too much caffeine include:
Cardiac arrest.
Disorientation.
Hallucination or psychosis.
Irregular heartbeat.
Muscle breakdown, called rhabdomyolysis.
Seizures.
The overdose risk increases if you use dietary liquid or powdered caffeine supplements, which often contain high concentrations of caffeine. For example, just one teaspoon of powdered caffeine has the same amount of caffeine as 28 cups of coffee.
Why you should space out your caffeine intake
When you consume caffeine, it takes 45 to 60 minutes before you start to feel it. The stimulant effects can last between three to five hours.
Consuming too much caffeine all at once or having caffeinated products too close together in your day can lead to bothersome and dangerous side effects. Remember, limit your caffeine intake to 400 mg a day. And when possible, space out your caffeine intake by three to five hours, to reduce the risk of side effects.
To keep caffeine from interrupting your sleep, the American Academy of Sleep Medicine recommends avoiding caffeine at least six hours before bedtime. So, if you go to bed at 10 p.m., stop consuming caffeine by 4 p.m.
Who should avoid caffeine?
Some medical conditions may make it more likely to have side effects from caffeine. Talk to your doctor about what amount of caffeine is safe for you if you have:
Cardiovascular disease, especially irregular heartbeat.
High blood pressure.
Severe anxiety.
Peptic ulcer disease or gastroesophageal reflux disease (GERD).
Liver or kidney disease.
Seizures.
The bottom line on caffeine
Different people can experience the effects of caffeine differently. If you experience side effects from caffeine, see the specialist team at Luminis Health. They can help figure out why you may be more sensitive to caffeine.

A trimester-by-trimester guide to safe exercise during pregnancy
Blog
Years ago, doctors recommended rest and limited activity to expecting moms as they progressed through each stage of pregnancy. While you should always check with your health care provider on what would be best for you and your baby, staying active during your pregnancy has shown to ease back pain, improve your mood, and prevent the risk of gestational diabetes and pregnancy-induced high blood pressure. Exercise will also help you maintain a healthy weight during pregnancy and may reduce your risk for a Cesarean section.
Physical activity will not increase your risk of miscarriage, low birth weight or early delivery. But there are some safety tips you should keep in mind:
If you’re new to exercise, your heart rate should stay below 150 bpm.
Stay well hydrated before, during and after exercise.
Eat a snack or drink juice 15-30 minutes before you exercise.
Stop if you become dizzy, short of breath or experience any bleeding.
Do not exercise outside when it is very hot or humid.
As your body makes room for your growing baby, you may wonder which exercises are safe during each trimester.
Learn your risk for heart disease with our free online heart health profiler and take the first step toward having a healthy heart for life.
First Trimester
I wouldn’t start training for a marathon just yet, but if you are able to work through the first-trimester morning sickness and fatigue, going for a brisk walk is a great exercise during this stage. But if you’re just getting started, walk 10-15 minutes a day and gradually increase to a 30-minute walk 3-5 times a week.
For women without pre-existing health conditions, moderate activity does not have heart rate limitations. This is especially true for women who were exercising prior to pregnancy. If you were highly active before getting pregnant and remain healthy, you can continue.
Second Trimester
Has your morning sickness and fatigue decreased? You may find you have more energy in your second trimester. However, as your joints begin to loosen, you are at a greater risk for injury (like sprains and strains).
At 14 weeks, we recommend avoiding activities like skiing, contact sports, karate and other activities that increase your risk of falling. You may continue with walking, swimming and pre-pregnancy exercise as long as it isn’t high-impact or lifting weight over 25 pounds. Prenatal yoga and stretching can also be very beneficial and help increase your strength and flexibility as you prepare for childbirth.
Third Trimester
The best workouts for your third trimester are swimming, walking and biking in a reclined exercise bike. Prenatal yoga is still a good option for this stage as you get ready to deliver your baby. If you’re continuing with weight resistance exercises, it’s okay to lighten the load. Modifying bicep curls to about 3-5 pounds will still help keep your arms toned.
Some women work out through the end of their pregnancy, but some may stop. Either way, it’s important to listen to your body and talk with your doctor. Patients with the following conditions should especially ask their provider before starting exercise: heart and lung conditions, cervical problems, low-lying placenta, high blood pressure later in pregnancy, and vaginal bleeding and cramping.
As always, it is best to discuss any questions or concerns with your obstetric provider.
