How Long Do the Effects of Caffeine Last? 

The most important thing to remember is that most of the caffeine you drink is ‘absorbed within 45 minutes’

‘The effect peaks at around the hour mark, but the average time it takes to metabolise half the caffeine for most people is five hours,’ Aidan said. 

‘A typical person will get through the next half in another five hours (it’s “half life”) and so on.’ 

The expert said that this ‘half life’ does vary from person to person, and can range from a speedy hour and a half to nine and a half hours, depending on a number of factors.

Caffeine breaks down primarily in the liver. It stays in the blood for anywhere from 1.5 to 9.5 hours.

One cup of coffee can take as little as 20-25 minutes to reach the bloodstream and about 1 hour to reach full effectiveness. Some factors, like smoking, fasten the breaking down of caffeine. On the other hand, pregnancy and oral contraceptives can lower the breakdown.

Caffeine Withdrawal Symptoms

There are several side effects of caffeine overconsumption. If one consumes too much caffeine, they become caffeine-dependent. If one decides to stop consuming caffeine suddenly, it is known as caffeine withdrawal syndrome. Some signs of caffeine withdrawal include impaired behavioural and cognitive performance, decreased or increased blood pressure, reduced motor activity, increased heart rate, hand tremor, increased diuresis, skin flushing, flu-like symptoms, nausea/vomiting, constipation, muscle stiffness, joint pains, and abdominal pain.

The symptoms of caffeine withdrawal can last between 2 and 9 days. The peak intensity of symptoms occurs 24–51 hours after one stops caffeine.

There are several ways to reduce the symptoms. Re-administration of caffeine is one of them. It is advised to decrease caffeine consumption gradually to prevent the caffeine-withdrawal syndrome. Some symptoms, such as headache or gastrointestinal symptoms, are treated with medications. On the other hand, one can improve constipation by increasing dietary fibre consumption or over-the-counter medications. Oral or intravenous hydration and rest/sleep can alleviate many symptoms of caffeine withdrawal as well.
