Insomnia is a sleep disorder that affects millions of people worldwide, causing difficulties falling asleep, staying asleep, or experiencing non-restorative sleep. One of the main causes of insomnia is caffeine consumption. Caffeine is a stimulant that is found in many beverages and foods, including coffee, tea, chocolate, and energy drinks. Read on as we explore the relationship between caffeine and insomnia, the effects of caffeine on sleep, and ways to reduce caffeine consumption for better sleep.
What is Insomnia?
Insomnia is a sleep disorder characterised by difficulty falling or staying asleep or experiencing non-restorative sleep. It can cause fatigue, mood disturbances, and cognitive impairment. Insomnia can be acute or chronic, with the former lasting up to three months and the latter lasting for more than three months.
What is Caffeine?
Caffeine is a colourless and flavourless addictive stimulant that is commonly found in coffee, tea, chocolate, and energy drinks. It stimulates the central nervous system, increasing alertness, and reducing fatigue.
How does Caffeine Affect Sleep?
Caffeine affects sleep by blocking the action of adenosine, a neurotransmitter that promotes sleep. It increases the production of other neurotransmitters such as dopamine and norepinephrine, leading to increased alertness and wakefulness. The effects of caffeine can last for several hours, with half of the caffeine consumed being eliminated from the body within five hours.
How Much Caffeine is Safe?
The safe amount of caffeine varies depending on the individual’s tolerance and sensitivity. Generally, moderate caffeine consumption up to 400 mg per day, is considered safe for most healthy adults. Excessive caffeine intake can cause adverse effects, including anxiety, nervousness, tremors, and insomnia.
