Caffeine inhibits the secretion of melatonin and delays the onset of sleep.

However, the specific tolerance level may vary depending on individual differences.

To avoid the discomfort caused by caffeine overdose, it is recommended to spread coffee consumption throughout the day rather than drinking a large amount at once. For example, you can enjoy coffee in the morning and lunch time, and avoid drinking it in the late afternoon or evening, which can reduce the interference with sleep.

In addition, choosing low-caffeine coffee varieties or alternatives, such as decaffeinated coffee, is also an effective balancing strategy. Controlling coffee intake is especially important for people with sensitive constitutions or health problems.
