Why Can Coffee Make You Tired in the Afternoon?
Coffee is often the go-to beverage for a quick energy boost, especially during a long working day. But despite its reputation as a stimulant, some people report feeling sluggish after their afternoon brew. This paradoxical effect isn’t just in their heads – there are physiological explanations behind why coffee might make some feel tired rather than energised.
The Role of Caffeine
Caffeine works by blocking adenosine receptors in the brain. Adenosine is a chemical that promotes sleep and gradually builds up during the day, signalling when it’s time to rest. By blocking this process, caffeine temporarily boosts alertness. However, it doesn’t stop the body from producing adenosine. Once the caffeine wears off, all that built-up adenosine binds to receptors at once, leading to a sudden crash in energy, often experienced in the afternoon.
People who consume coffee regularly can develop a tolerance, prompting the brain to create more adenosine receptors in response. Over time, this reduces the perceived effects of caffeine and can contribute to fatigue. Factors such as dehydration, blood sugar fluctuations and inadequate sleep can play a role in caffeine-related tiredness.
There are also metabolic differences. Genetics, age and hormonal changes affect how individuals metabolise caffeine. For some, the stimulating effects fade quickly, leaving them drowsy shortly after their coffee wears off.
Balancing Coffee with Other Habits
To avoid the post-coffee slump, experts suggest spacing out caffeine consumption and avoiding it later in the day. Staying hydrated, pairing coffee with protein-rich snacks and ensuring a balanced lunch, often easily arranged via an office lunch delivery, can also help stabilise energy levels. Services such as //www.crumbsdelivered.co.uk/shop/office-lunch-delivery can provide coffee with lunch, but these kinds of services also offer options designed to support productivity without relying on caffeine alone.
