Some people rely on caffeine every day.
For many, coffee or another form of caffeine is part of routine and, in our heads, is the key to starting a day off on the right foot. There are dozens of ideas and messages out there about caffeine's impact on the body. WebMD is putting some of the myths to rest with a list of the most common caffeine myths.
Here are the top four:
#1 Caffeine is addictive: Caffeine causes physical dependence but does not threaten your physical, social or economic health in the way addictive drugs do. If you stop taking caffeine, you may suffer from withdrawal symptoms like headache, fatigue, anxiety or irritability.
#2 Caffeine can cause insomnia: Because your body can absorb caffeine, it can also rid itself of it. Most people's sleep will not be affected by a cup of coffee in the morning. Caffeine later in the day could affect or interfere with your sleep but it will not cause insomnia.
#3 Caffeine increases risk for conditions such as osteoporosis, heart disease and cancer: Moderate amounts of caffeine will not harm most healthy adults. People with high blood pressure or older adults may be more vulnerable to its effects.
#4: Caffeine is harmful for women trying to get pregnant: Several studies show no link between low amounts of caffeine and trouble conceiving , miscarriage, birth defects or premature birth.
