Can Caffeine Keep You Awake at Nights

Caffeine is the main ingredient in not only fat burners but also for most energy drinks around the world. It is a natural substance derived from coffee beans and other plant sources. It’s also a popular central nervous system stimulant. 

According to the American Academy of Sleep Medicine, caffeine acts like a drug to promote alertness. It has a role as an adenosine receptor deterrent and blocks the adenosine receptor

Now, adenosine is an element in our bodies that induce sleepiness. Caffeine hinders sleep by blocking the adenosine receptor. 

Half of the caffeine we consume leaves our body by 3 to 5 hours. The rest of the caffeine remains in our system for a long time. As a result, you might feel more alert and less sleepy. 

Caffeine can also disrupt sleep through a number of ways-

  • It delays the timing of our physical clocks
  • Increases heart rate
  • Increases sleep latency
  • Reduces sleep quality and quantity

Various studies have noted the detrimental effects of caffeine on sleep. It’s a proven fact now that too much caffeine can indeed cause sleeping problems. 

Other Fat Burner Ingredients and Sleep Problems

Different forms of tea extracts like green tea extract contains caffeine. So they will also lead to sleep issues in some individuals. 

The fat loss supplement may also contain other ingredients that act as stimulants. For instance, Yohimbe, another plant extract, is also a stimulant. According to WebMD, it can also cause a racing heartbeat and keep you awake. Plus, it also leads to sleep problems in other ways. 

Another ingredient, garcinia Cambogia too, may decrease your need for sleep. 

Summary: Various ingredients in fat burning supplements can reduce sleep quality and the time you sleep. Of course, this is not applicable to all individuals. 

Can Taking Fat Burner in the Morning Solve Sleep Problems

Some people wonder if taking fat burner supplements in the morning will help you sleep better. The logic is, if we take the supplement in the morning, then our bodies get enough time to clear the stimulants. 

This logic can be partly true. In the case of caffeine, our bodies take 3 to 5 hours to remove 50% of the caffeine we consume. So if you take your fat loss supplement in the morning, our bodies may get enough time to clear it off. 

However, the effects of caffeine can remain even if you take it during the early afternoon or evening.

American Academy of Sleep Medicine says taking caffeine 6-hours prior to sleeping cuts back total sleeping time by 1 hour.

The effects can be stronger in older folks who take more time to process caffeine. 

Summary: Taking your fat burner in the morning may lessen the effects of the stimulants.
