For example, if you want a sounder sleep, you should avoid taking large amounts of caffeine late at night, and you should always choose to have your first coffee after breakfast, and not on an empty stomach.

Otherwise, you could experience poor sleep quality that will weaken the body’s immune system and make you more susceptible to various infections, such as flu or cold.

  • Increased blood pressure
  • Tachycardia
  • Palpitations, and
  • Arrhythmias

Other Drinks To Avoid Before Going To Bed

You cannot deal with restless nights anymore? There is a real chance that your body is stress because you drinking something that could be harming you. What we eat and drink affects our sleep patterns and lifestyle.

The wrong drink at the wrong time can lead to poor sleep quality and how long you get to sleep.

Here are drinks, next to energy drinks, that can easily disrupt your sleep:


It’s no secret that alcohol makes you drowsy.

You may think that alcohol helps you sleep, but in reality, there are more negative than beneficial effects of drinking alcohol before bed.

Alcohol forces you to urinate at the night, which can easily disrupt your sleep pattern.

It can also decrease your rapid eye movement (REM) sleep and fragment your sleep.

Alcohol can also worsen the severity of breathing problems during sleep. These problems often includes sleep apnea and snoring.


As mentioned earlier, caffeine gives you energy and can make you suffer in terms of sleep.

Drinking coffee too often and in large amounts can lead to sleep-related issues, and beyond. What about decaf? Even decaf coffee contains caffeine, so be careful.


Isn’t water what makes us move? Yes, but too much of it can disturb our health in some way.

You should stay hydrated all day long, but you shouldn’t drink large amounts of water close to your bedtime.

A glass of water is fine, as it can even help with overall health overnight, but unlimited water can create more issues than benefits. Plus, too much water can lead to frequent bathroom visits.

Try to drink less water in the evening to avoid waking up in the middle of the night.

The Bottom Line

Unless you are drinking water in a fair amount before sleep, you should avoid beverages.

Energy drinks are popular sugary drinks that are heavily marketed, that people believe they cannot survive without it.

However, there are far better and healthier options that can help you get that extra boost for workout time and overall alertness.
