Coffee is a favourite beverage for many. While primarily people drink it to wake up and feel more energised, it is also rich in antioxidants, which may benefit your liver, heart, and overall health. But did you know that your last cup for the day should be before 3 pm?
How coffee works in your body
On August 14, Dr Alok Chopra, a cardiologist with over 40 years of experience, explained in an Instagram post why we should completely avoid drinking coffee past 3 pm. He also explained how coffee works in our bodies, the science behind it, and why drinking coffee later in the day is harmful even if you sleep afterwards.
Explaining why your last cup of coffee should be before 3 pm, Dr Alok wrote, “Coffee may wake you up, but caffeine can stay in your system for hours. Even if you fall asleep easily, late caffeine may affect the quality of your rest. Try making your last cup before 3 pm for better sleep and next-day energy.”
The science behind your coffee high
According to the cardiologist, caffeine blocks adenosine in our body. It is the chemical that naturally builds up in your brain and signals it's time to rest. He added, “At the same time, caffeine stimulates the release of adrenaline and cortisol, making you feel more awake, alert, and focused.”

‘But I sleep fine after coffee…’
Many people allow themselves to drink coffee later in the day or in the evening, claiming they can easily fall asleep after going to bed. However, caffeine not only impacts your ability to sleep, but also your recovery, the cardiologist claims.
According to the cardiologist, “You may fall asleep, but your body may not recover as well. Late caffeine can reduce deep sleep, delay melatonin release, and leave you feeling less refreshed the next morning.” He added, “Finish your last cup by 3 pm for better sleep and next-day energy.”
