Understanding Caffeine Sensitivity
Caffeine is the most widely consumed psychoactive substance in the world. Found naturally in coffee, tea, chocolate and other foods, caffeine provides many people with a much-needed energy boost to get through the day.
However, not everyone can tolerate caffeine well. Some experience side effects like insomnia, headaches, irritability and the dreaded caffeine jitters. Caffeine sensitivity is connected to factors like genetics, age, medical conditions and medication use.
By understanding what causes caffeine jitters and oversensitivity, you can take steps to enjoy your favorite caffeinated beverages more comfortably or explore suitable lower-caffeine or caffeine-free alternatives.
What Are Caffeine Jitters?
Caffeine jitters refer to feelings of jitteriness, shakiness and anxiety after consuming caffeine. Your hands may tremble or feel unsteady. You may also feel energetic, wired and unable to sit still.
These effects result from caffeine stimulating the central nervous system. It causes a cascade of hormonal effects, increasing adrenaline production. Blood pressure, heart rate, respiration and blood glucose levels rise.
This boost can help you feel more alert and focused. However, some people experience the jittery feelings as unpleasant symptoms, especially in larger caffeine doses.
Factors That Increase Caffeine Sensitivity
Caffeine jitter symptoms typically appear above 400mg of caffeine per day for healthy adults. However, the following factors can make someone more prone to experiencing negative effects at lower caffeine intakes:
- Genetic variants regulating caffeine metabolism
- Youth or old age
- Anxiety disorders
- Hypertension
- Premenstrual syndrome or menopause
- Medications that impair caffeine breakdown
Additionally, sporadic or infrequent caffeine intake can make you more susceptible to side effects compared to regular daily use. Starting back after a break causes a larger spike in caffeine blood levels.

FAQs
How does dehydration cause proteinuria?
Dehydration thickens the blood and decreases kidney filtration, allowing more protein to leak into the urine. Drinking water helps dilute the blood and improves filtration.
What are signs of dehydration?
Signs include increased thirst, headache, fatigue, darkened urine, dry mouth, dizziness, and constipation. Pay attention to your body's signals.
How much water should I drink daily?
There's no universal recommendation. Drink enough to quench thirst and keep urine light yellow. Intake needs are higher for active individuals or hot environments.
What foods and drinks hydrate besides water?
Non-caffeinated, non-alcoholic beverages like herbal tea, milk, and 100% fruit juice can contribute to hydration. Fruits and veggies with high water content also hydrate.
When should I see a doctor for proteinuria?
See your doctor if protein in urine persists beyond 1-2 weeks of proper hydration or recurs frequently. This may indicate an underlying kidney condition.
