Why is it recommended to drink coffee before bed?

In daily life, we often hear various advice and warnings about coffee. Some people say that drinking a cup of coffee in the morning can refresh the brain, while others believe that drinking coffee in the evening will affect the quality of sleep. However, studies in recent years have shown that in some cases, drinking coffee before bed may be beneficial to our body and brain.

1. Improve memory

Many people know that caffeine is a stimulant that can improve focus and alertness. This is why many people choose to drink coffee in the morning to help them wake up and start the day. However, a moderate caffeinated beverage in the evening or close to bedtime may also have a positive effect on memory.

According to new research, consuming moderate amounts of caffeine during learning can enhance long-term memory and improve information retrieval, which means that if you drink a cup of coffee when you are learning new knowledge or need to remember important information, it may have a positive impact on your memory.

2. Improve athletic performance

In addition to its benefits for brain function, drinking coffee before bed may also improve athletic performance. Numerous studies have shown that, in moderate doses, caffeine can increase muscle contraction force and endurance, and reduce perceived fatigue.

This means that if you are someone who works out in the evening or participates in late-night sports activities, a moderately caffeinated beverage may give you a boost of energy and stamina. However, be careful not to rely too much on caffeine to delay fatigue, and make sure to end your activity at a suitable time to get enough rest.

3. Relieve anxiety and depression

Although long-term excessive caffeine intake may lead to psychological problems such as anxiety and depression, temporary and moderate caffeine intake has been shown to relieve mild symptoms of anxiety and depression.

Caffeine can stimulate the central nervous system and promote the release of dopamine and norepinephrine, thereby improving mood and psychological state. Therefore, in some specific situations, such as facing important exams or stressful work tasks, moderate caffeine intake may help relieve anxiety and improve psychological state.

4. Extend wakefulness

If you need to stay awake at night and are unable to adjust your body clock by going to bed earlier, a moderate caffeinated beverage before bed may be a good option.

According to research, consuming caffeine at the right dose can prolong wakefulness and reduce sleepiness. This is especially important for people who need to stay alert for activities such as working or driving at night. However, please be careful to control the dose to avoid affecting normal sleep quality.

Summarize

Although many people believe that drinking coffee in the evening will affect the quality of sleep, new research shows that in moderate consumption, drinking coffee before bed may be beneficial to our body and brain. It can enhance memory, improve athletic performance, relieve anxiety and depression, and prolong wakefulness.

However, it is important to note that everyone has different levels of sensitivity to caffeine, so it is best to understand your body's reaction before drinking coffee before bed. Also, avoid excessive caffeine intake and mixing it with other stimulants.

All in all, if you're looking to get some extra energy in the evening or improve brain function, a moderate bedtime caffeinated beverage might be an option worth trying.
