Around 100 million cups of coffee are drunk daily in the UK, making it one of the nation's favourite drinks. But the beverage could be a detriment to one of the most important aspects of our wellbeing if consumed after a certain time, a doctor has warned.

While coffee has some great health benefits, including reducing the risk of developing type 2 diabetes, some could see a negative effect, reports the Express. Doctor Poonam Desai, known as @‌doctoranddancer on TikTok, has shared the reason she avoids drinking it after 12pm.

She told her 22,000 followers there was one one specific reason for her cut off. She said: "Caffeine has a half-life of five to six hours and could still be lingering in your system close to bedtime, preventing us from falling asleep or staying asleep. So I really try to avoid any caffeinated beverages in the afternoon."

Although it might not seem like a huge issue, sleep deprivation has been linked to a number of serious chronic health issues. This includes heart disease, high blood pressure, obesity and depression.

Numerous research studies also back up Doctor Desai's advice, including one published in the journal of Science Translational Medicine in 2015, which showed the drinking the equivalent caffeine to that in a double espresso could push the body clock back by an entire hour.
