Why do some people drink coffee before going to bed and still sleep well?

It turns out that there are people who can still sleep well despite having a cup of coffee right before. This can happen to you or anyone!

There are many people who like to drink coffee in the morning and make sure not to drink it in the evening to avoid affecting their sleep. However, there are people who can still sleep well even though they drink coffee before going to bed.

It may sound strange, but scientists have discovered something called the 'caffeine gene', which is a special gene that controls the body's response to caffeine and how quickly the body responds to it.

How does caffeine work?

During the day, even if you feel refreshed after a good night's sleep, your body slowly begins to produce adenosine, which is an important substance that helps regulate the body's sleep-wake cycle.

During the day, adenosine levels will increase, helping you to fall asleep naturally at night.

When you consume any caffeinated beverage like coffee, the body perceives caffeine as adenosine and stops producing adenosine because it is tricked into thinking that there is enough adenosine inside the body.

However, caffeine does not work like adenosine and it prevents your body from feeling tired and sleepy.

Some people drink a cup of coffee before going to bed and still sleep well.

Why are some people unaffected by caffeine?

There are 3 reasons for this:

1. There may be other substances produced by the body besides adenosine that make people tired faster.

2. Adenosine in the body is strong enough to prevent caffeine from working.

3. Caffeine is processed by the body too quickly and may have been eliminated from the body before it started working.

As a result, some people can enjoy a cup of cappuccino right before bed and still sleep well through the night.

In case you still want to enjoy a cup of coffee before bed, you can opt for a decaffeinated cup of coffee or wait until the next morning to enjoy this drink to its fullest!
