Cardiologist Warns of Coffee Before Bed and Names Best Time for Last Cup

The habit of drinking coffee in the afternoon can turn into problems with night rest. Cardiologist Marcos Cairo told how many hours before bedtime it is worth giving up the invigorating drink to avoid unpleasant consequences. This is reported by the publication Metropoles.

According to the expert, it is advisable to drink the last cup of coffee no later than six to eight hours before going to bed. The fact is that caffeine retains its effect much longer than the initial rush of vivacity is felt.

The doctor explained that the half-life of caffeine is an average of five to six hours. For example, if you drink coffee at 16:00, then even by 22:00 about half of the dose received will still remain in the body and continue to affect the nervous system.

As a result, a person may have difficulty fully recovering during a night's rest. As the cardiologist warned, later coffee consumption can make sleep less deep, cause frequent awakenings and significantly worsen its quality.
