Many reach for a cup of coffee immediately after rising from bed. Though drinking coffee has its benefits, caffeine can have several negative side effects, particularly when consumed excessively.
High levels of caffeine can lead to jitteriness, anxiety, insomnia, and an increased heart rate.
Withdrawal symptoms such as headaches and fatigue can also occur when caffeine consumption is suddenly stopped.
Drinking coffee late in the evening could affect the circadian rhythm of the body. Circadian rhythm is the body’s natural 24-hour cycle that regulates sleep, wakefulness and other bodily functions.
Consuming coffee too close to bedtime in the evening could disrupt your sleep cycle. It is recommended to avoid consuming caffeine for a minimum of 6 hours before bed.
Experts also point out that excessive caffeine intake can lead to dehydration and nutrient imbalances.
The best time to drink coffee in the morning is 9:30 am to 11:30 am when the cortisol level is lower.
Healthy individuals can consume up to 400 mg of caffeine daily.
