    • A teenager or a person from age 13 to 18 has a caffeine limit of about 100 milligrams a day. The reason for the low caffeine limit is because teenagers are growing and they need 8-9 hours of sleep each day. 100mg caffeine is equivalent to 1 large mug of coffee or 2 cups of tea plus a milk chocolate bar.
    • Children that are below the age of 13 should avoid caffeine. It is not at all good for them to consume a high stimulant substance like caffeine.
    • The maximum amount of caffeine intake for pregnant women is 200 milligrams per day, this is equal to two cups of tea and a large mug of coffee.

    Does Caffeine Affect Sleep?

    A high dose of caffeine may hurt sleep. As caffeine is a substance that encourages alertness, the most obvious effect of caffeine is that it makes falling asleep harder. A study even claims that caffeine intake can disrupt the timing of your body clock, which means that your eyes will be wide open even after your bedtime had passed.

    Caffeine also reduces your total sleep time. It also disrupts sleep cycles, meaning you will not enjoy deep sleep as you used to.

    Your body membranes absorb caffeine very fast. This means that you will start feeling caffeine’s effect within 15 minutes of consuming it. Caffeine stays in your body for about 5-6 hours and will eventually get discharged through urine.

    Note: Do not take coffee, tea, or any major source of caffeine close to bedtime, as this might disturb your sleep schedule and will reduce the sleep quality.
