How To Stay Awake While Driving Without Caffeine

How to stay awake while driving without caffeine

To stay awake while driving without caffeine it is important to stay hydrated by drinking plenty of water. Try to exercise during regular breaks and seek out well-lit areas to slow down the release of melatonin. If you feel too tired to drive, always stop somewhere for the night and resume your journey after a good night’s sleep.

  • Hydration is Key: Keeping yourself hydrated can help maintain alertness. Drink plenty of water throughout your journey. Dehydration can lead to fatigue, so make sure you have a water bottle handy.
  • Rest Up Beforehand: Ensure you get a good night’s sleep before you embark on your drive. Starting your journey well-rested can make a significant difference in your alertness levels.
  • Bright Lights: Melatonin, a hormone responsible for regulating sleep, is produced in higher quantities in the dark. Taking breaks in brightly lit areas can help in reducing its production, thereby aiding in keeping you awake.
  • Stay Cool: Open the windows periodically to allow fresh, cool air into the vehicle. The drop in temperature can act as a natural stimulant and help combat drowsiness.
  • Engage Your Senses: Playing upbeat music can elevate your mood and alertness. Furthermore, maintaining good posture by sitting up straight can keep your body active and your mind focused.
  • Know When to Stop: If you ever feel unsafe or too drowsy to continue, it’s essential to stop at a rest area or hotel. It’s always better to arrive late than not at all.

The Caffeine Paradox

For those accustomed to relying on coffee or other caffeine sources to stay awake, it’s essential to understand the temporary nature of caffeine’s effects and its potential aftermath. Caffeine blocks adenosine receptors in our brains. Adenosine is a neurotransmitter that accumulates throughout the day, promoting sleepiness. When we consume caffeine, it temporarily prevents us from feeling this sleepiness by blocking its effects.

However, adenosine continues to build up in the background. Once the caffeine starts wearing off, there can be a sudden and pronounced binding of accumulated adenosine to its receptors, leading to an abrupt onset of sleepiness – sometimes even more profound than if one hadn’t consumed caffeine at all. This phenomenon, where the alertness from caffeine is followed by a sudden crash in wakefulness, can be especially problematic for drivers.

10 Science-Based Hacks On How To Stay Awake While Driving Long Distances

When you’re tired, cognitive performance decreases, and drowsiness kills more people on the road than drugs and alcohol combined. It’s important to stay alert while driving to prevent an accident.  The National Highway Traffic Safety Administration estimated that in the United States, there were 90 000 traffic incidents involving drowsy driving in 2015.

Below are my top tips for how to stay awake while driving. If you think you are putting yourself or others at risk on the road please stop and get some rest!

how to stay awake while driving

Get at least 7 hours of sleep the night before

“Sleep is the greatest legal performance enhancing drug that most people are probably neglecting”

Dr Matthew Walker, PHD – Author of Why We Sleep: Unlocking the Power of Sleep and Dreams

There is no substitute for a full night’s sleep before a long drive. When under-slept, you are susceptible to micro-sleeps which are temporary lapses in focus. Sleep is crucial for health and recovery and sleep studies have shown that after being awake for 20 hours you can be as impaired as an individual that is legally drunk.

The average American sleeps just 6 hours and 31 minutes during the week (It used to be 7.9 hours in 1942). Planning ahead and ensuring a full night’s sleep the evening before is the best way to stay awake while driving the following day.

Drink water as well as caffeine

“Symptoms of dehydration include feeling tired” – NHS, UK

Caffeine is the most commonly used stimulant in the world with the effect of increasing alertness, concentration, and focus. However, caffeine is also a diuretic, and prolonged consumption during a long drive can lead to dehydration.

Ensure you drink a considerable amount of water to avoid any dehydration-induced fatigue or tiredness on the road. After all, a whopping 60% of your body weight is from water.

The recommended amount (Institute of Medicine) is around 3 liters for a male and a little over 2 liters for a female per day. The best energy drink to stay awake while driving according to is Red Bull, closely followed by Monster. You can still stay awake while driving without caffeine.

Avoid excessive unhealthy snacks

Refined sugars and carbohydrates such as those found in sweets and sugary soft drinks may give you a temporary boost.


The subsequent insulin spike can increase tiredness on the road significantly.

Try to avoid that carb crash by eating a banana, salad or another healthy snack. This will give you a gradual energy release as opposed to a sudden spike.

With less sleep, the hunger hormone ghrelin gets ramped up, so it might seem difficult to resist the temptation to feast on sugary snacks! Do your best to avoid them unless you need a final boost at the end of the journey.

Take a break in a well-lit area a few hours before your normal bedtime

“One hour of iPhone use will delay the onset of melatonin production by about 3 hours”

Dr Matthew Walker , PHD – Author of Why We Sleep: Unlocking the Power of Sleep and Dreams

Melatonin is a hormone released by the body prior to sleeping. It creates a feeling of sleepiness as the body prepares for rest. Incandescent light bulbs and smartphone screens can suppress the release of this hormone.

So how is this important?

Taking a break in a well-lit service station after it’s gone dark, a couple of hours before you would normally go to bed can delay tiredness.

Pro tip:

If you are using a laptop, consider trying Flux which is software that reduces the output of this light in the evening (when you do want to sleep).

Take a power nap

Taking a short nap can help you feel refreshed, more alert, and in an improved mood by tackling your sleep deficit. According to Dr. Sara C. Mednick, keep the nap short (10-20 mins) to avoid going into a deeper sleep that may make you feel drowsier after you wake up due to sleep inertia.

You can find more info in our article on how frequently you should take breaks when driving long distances.

Exercise during Breaks

When taking a break, try to take a walk or do some stretches. This increased blood flow will not only benefit your alertness but will help avoid back pain or muscle aches caused by a prolonged period of sitting. Whilst in the car try to sit upright and move positions regularly to avoid strain.

Open the driver window and opposite rear window

This should create a flow of air that will wake you up. A cold blast of air can be great for a temporary reduction in tiredness.

Occupy the Brain with a Task

This could be making a phone call or even something as simple as playing a road trip game such as the license plate game. Keeping your mind distracted and active will prevent it from going into a relaxed state that occurs just before sleep.

Listen to a Podcast

Becoming engaged in a conversation can keep you more alert than listening to the melodic beat of your favorite music tunes. Keeping the brain active and thinking about the podcast topic can help you focus on the road.

Do not consume any alcohol before or during driving as any amount can lead to drowsiness

Alcohol is a sedative and any amount consumed can influence drowsiness. If you have a long drive, don’t consume any on the day of the trip.

But that’s not all…

Try to avoid alcohol consumption the night before your drive, too.


Drinking impairs the body’s ability to enter crucial REM sleep, meaning you won’t be well-rested before your drive.

Additional Quick Tips For Staying Awake When Driving

  1. Plan and have a second driver so that you can take turns (whilst the other rests)
  2. Keep to the speed limit. Driving fast is not only dangerous but also more cognitively draining
  3. Plan ahead and avoid late-night driving where possible
  4. Have a conversation with other passengers to keep your mind occupied

Drowsy Driving Prevention

drowsy driving

Within this article, we have already discussed the top tips for staying awake while driving. It’s also important to reinforce the point that drowsy driving is responsible for numerous accidents per year due to the significant reduction in driver competency. Driving is intricate and requires continued concentration.

National Sleep Foundation Advice

The National Sleep Foundation gives these tips to recognize when you might be too tired to drive:

  • Difficulty focusing, daydreaming, or wandering thoughts
  • Heavy eyelids, yawning, and repeatedly rubbing your eyes
  • Memory difficulties such as forgetting the last few miles
  • Struggling to keep your head up
  • General irritability
  • Restlessness

Driving behaviors can include:

  • Drifting across lanes or hitting the shoulder rumble strip
  • Misunderstanding traffic signs or failing to turn off at the right exit

Always take breaks if you need to

If you feel tired, stop at a service station and get some sleep or check into a hotel and finish the drive in the morning. It’s much better to arrive at your destination safely.

Who is at risk of drowsy driving?

drowsy driving prevention

Everyone is at risk of drowsy driving.

Certain groups such as shift workers who work at night, those with undiagnosed sleep disorders or those working long/irregular hours might be more at risk.

The most crucial contributor is our circadian pacemaker. The body naturally regulates our body to sleep at certain times and this is a very powerful biological drive.

During deep REM sleep, our body paralyzes itself so we can dream safely. Mother nature would not put us in such a vulnerable state if it were not for the crucial importance of a good night’s sleep for health and well-being.

Quick Tips to Get Better Sleep

  1. Reduce alcohol consumption (Alcohol inhibits the body’s ability to enter REM sleep)
  2. Turn down the lights in the house 3 hours before bedtime (incandescent light bulbs suppress melatonin)
  3. Install Flux on your computer and try not to view screens late at night. One hour of iPhone use can delay the onset of melatonin production by 3 hours
  4. Keep your room cool. Your body needs to drop its temperature by 2-3 F to sleep
  5. Ensure you get at least 7 – 9 hours of sleep per night

Why do I get sleepy while driving?

sleepy when driving

Driving is a complex task requiring focus, concentration, and a continuous stream of decisions and micro-adjustments. It is natural to become tired throughout the journey in a car as we get closer to our normal sleeping time.

As previously mentioned, the body releases the hormone melatonin, and the signs of drowsiness gradually surface.

If you find that you are getting sleepy while driving in the daytime, here are some possible reasons:

Possible Sleepiness Causes

  • Accumulation of a sleep deficit by not getting the required number of daily hours of sleep (7-9hours)
  • Undiagnosed sleep disorders such as narcolepsy, sleep apnea, or restless leg syndrome
  • Alcohol consumption has affected the quality of sleep you have been getting (alcohol makes it more difficult for the body to enter REM sleep)


Key Points

After many hours behind the wheel, I can safely say that there is no substitute for a solid 8 hours of sleep the night before a journey. Planning to ensure a manageable distance also goes a long way.

There have been a few occasions during my past road trips where poor planning lead to me booking a hotel a huge distance away.

The result?

A tough 10-hour drive. 

It’s much better to break the drive down into manageable chunks and always try to ensure as much daytime driving as possible to avoid competing against the body’s natural drive for sleep.

Stay safe on the roads and follow these tips on how to stay awake while driving!
