Eau Claire and Chippewa Falls, Wis.  –  Caffeine is in more products now than ever; soda, smoothies, candy, energy drinks, granola bars, water, etc. As part of March’s Caffeine Awareness Month, HSHS Sacred Heart and St. Joseph’s hospitals want to share how the stimulant affects our brain and body. 

The U.S. Food and Drug Administration (FDA) estimates 80% of U.S. adults consume caffeine daily. Although it can help with alertness, health experts say overdoing it can cause dangerous side effects including:

  • Increased risk of heart attack
  • Increased blood pressure
  • Insomnia
  • Skin aging and wrinkling
  • Headaches
  • Increased anxiety

One known effect of caffeine is how it negatively stimulates the adrenal glands. The adrenal glands sit on the kidneys and have a role in releasing hormones when we are confronted with stress. When caffeine is consumed, these glands are stimulated to release adrenaline into the body. This can affect sleep patterns and make us less alert in the morning and throughout the day.

“Caffeine is a stimulant and although it takes about 30 minutes to take effect, it can remain in your system for eight to 10 hours,” says HSHS Sacred Heart and St. Joseph’s hospitals Clinical Dietitian Betsy Fish.

The FDA recommends no more than 400 milligrams of caffeine daily for adults, however some people are more sensitive to the effects of caffeine and how fast it breaks down in the body, so less is recommended. Keep in mind, the amount of caffeine contained in foods and beverages varies widely.

  • 1 8-ounce cup of black coffee: 95mg
  • 1 8-ounce cup of green tea: 35-70 mg
  • 1 8-ounce energy drink: 50-250mg
  • 1 12-ounce can of cola: 40-50mg
  • 1 8-ounce can energy coffee: 145mg

Caffeine is not recommended for children, women who are pregnant or trying to become pregnant, and those who are breast feeding. It also should not be mixed with certain medications so talking with your health care provider about medication management is important. 

If you decide to lower your caffeine intake, Fish says drink more water to avoid dehydration and cut back gradually to avoid withdrawal symptoms such as headache and anxiety.
