Does DayQuil Keep You Awake?

Does DayQuil Keep You Awake? : Is the only medicine in your cabinet is DayQuil and, because it’s time for bed, you wanted to ask only one question “does DayQuil keep you awake”?

The answer is: NO, DayQuil does not keep you awake. DayQuil does not contain caffeine or any other type of stimulant that helps keep awake for longer. What it does is that it simply omits the antihistamine that is included in NyQuil (Helps to get drowsy), which can cause you drowsiness. DayQuil is essentially the non-drowsy version of NyQuil.

Pro Tip (if you are trying to stay awake with a cold): If you are using Dayquil and need an additional pick me up I use L-Theanine & Caffeine with Coconut MCT Oil , which helps me get over my cold faster and make the days more manageable.

Pro Tip (if you are trying to sleep with a cold): If you are using Dayquil and can’t sleep, it may be caused by the cold itself, while using NyQuil helps, I usually find using a diffuser with eucalyptus which works the best.

The two active ingredients in DayQuil, both the liquicaps and liquid, are acetaminophen for relieving pain from body and reducing fever, dextromethorphan for suppressing cough, and phenylephrine hydrochloride to help to get relief from nasal congestion. Both products contain the same ingredients and at same dosages. The dextromethorphan, which can cause drowsiness, is not at a high enough dosage in DayQuil to cause that side effect.

Vicks offers a line of DayQuil Severe, too. DayQuil Severe liquicaps, liquid, and caplets, just as with the original DayQuil, do not contain the antihistamine, nor do they have a stimulant of any kind. They consist of the same three ingredients and dosages as the original formula, but also with the addition of the expectorant guaifenesin.

In other words, no matter what version of DayQuil we’re talking about, the answer remains the same. Not on any cost, DayQuil will “keep” you awake. DayQuil will simply not cause drowsiness.

How does NyQuil compare to DayQuil?

NyQuil liquicaps and liquid also contain the acetaminophen and nasal decongestant, but additionally, they include the antihistamine doxylamine succinate, which is the ingredient known to cause drowsiness.

The NyQuil liquicaps actually have five milligrams more of the cough suppressant compared to both forms of the DayQuil, while NyQuil liquid contains three times the amount of dextromethorphan. NyQuil liquid contains as much as twice the amount of acetaminophen than its liquicap counterpart and the two types of DayQuil.

Finally, NyQuil Severe liquid and caplets contain the same amounts of acetaminophen, cough suppressant, and nasal decongestant as the DayQuil Severe liquicaps and caplets, as well as the same amount of antihistamine as the original NyQuil liquicaps and caplets formula. NyQuil Severe liquid, however, has double the amount of acetaminophen, cough suppressant, and nasal decongestant found in the DayQuil Severe liquid, and doubles the amount of antihistamine found in all other NyQuil products.

In other words, NyQuil products tend to have the same or higher dosages of the ingredients as DayQuil products, with the addition of the antihistamine. The other takeaway is that the NyQuil liquid formulas are, by far, the strongest of the NyQuil products.

Sleep Aids Safe to Take with DayQuil

Perhaps the initial scenario I provided is exactly why you searched this, and you next wondered what you could safely pair with the DayQuil to help relieve your symptoms, as well as get a good night’s rest.

Melatonin is not known to have any interactions with the ingredients in DayQuil. If you’ve never heard of melatonin before, it’s a hormone known to help regulate the sleep-wake cycle, and can be consumed as a supplement to help with short-term sleep problems.

You could also try Valerian Root; these are sleep aid supplements made from the Valerian plant. Valerian Root is not known to have an interaction with DayQuil, though it does have interactions with other medications. Follow this link to check the list of known interactions against the list of other medications you take before trying it.

An article from Healthline provides a list of seven additional natural sleep aids: magnesium, lavender, passionflower, glycine, tryptophan, ginkgo biloba, and L-Theanine. I took the time to cross-check each of these for interactions with DayQuil at and determined that all would be safe to consume along with DayQuil.

Again, you should always check your current medications for interactions with other medications or supplements before adding them to your regiment. This can be easily done at or with a simple Google search.

I personally recommend OLLY Restful Sleep Gummies (from Amazon) as my go-to sleep aid. I have used it with Dayquil before (after checking that it was safe), and they worked great together! If you are looking for something to improve your sleep I highly recommend them!

No, Alcohol is NOT a Sleep Aid

Did I just hear someone’s bubble burst?

I wanted to be sure to mention this because it is dangerous to combine alcohol with DayQuil. According to this article, taking alcohol with DayQuil can cause liver damage, among other things, and taking the two in high doses can result in “hallucinations, high blood pressure, and other dangerous side effects.”

Liver damage can occur due to the combination of acetaminophen and alcohol. Acetaminophen alone can be toxic to the liver, which is why combining it with alcohol increases the risk of liver damage. This is also why you should not take any additional acetaminophen when taking DayQuil, as too much acetaminophen is dangerous to your liver.

Dextromethorphan is also dangerous to mix with alcohol. Dizziness, lightheadedness, drowsiness, nausea, and vomiting are side effects of dextromethorphan, and alcohol can worsen them. The combination of the two can also result in liver damage, and combinations of high doses can even cause death.

Other Methods to Help You Sleep

A consistent schedule and bedtime routine

Not only does it help to have a regular schedule, i.e. getting up and going to bed at the same time each day, but it is also beneficial to have a bedtime routine. When our system is regulated by having a consistent schedule, our sleep-wake cycle is reinforced. A routine at bedtime will tell your body that it is nearing bedtime so you can begin to wind down.

Keep a quiet sleeping environment

Make your bedroom a relaxed and peaceful place. suggests employing a racket machine or earplugs to assist make noise the noise. you must also stop working all electronics in your bedroom thirty minutes to at least one hour before bedtime.

Dark and comfy

Avoid light exposure, including the blue light emitted from technology, a minimum of one hour before bed. Sunlight cues our brains to be awake and alert, and that we need time to wind down before having the ability to go to sleep. Our brains register the blue light as sunlight, which is why it’s equally important to get rid of exposure from it before bed. Healthline recommends using an eye fixed mask or blackout curtains to assist reduce the sunshine.

No caffeine after lunch states that caffeine can stay in your system for up to 12 hours, looking on how susceptible you’re to the substance. They recommend not consuming caffeine a minimum of four to 6 hours before bed, so it’s usually an honest rule of thumb to eliminate caffeine after lunch.

Time your meals, beverages, and exercises accordingly

Is it Safe to require Caffeine with DayQuil?

Maybe you would like to require some DayQuil and also must stay up. While DayQuil won’t keep you awake, it’s safe to consume caffeine with the medication. In fact, in keeping with Everyday Health, caffeine is employed in other products to extend the pain-relieving effects of acetaminophen, which, as mentioned above, is one in every of the active ingredients in DayQuil. So act thereupon morning cup of joe… it could even be extra helpful today!

The Answer Was alleged to be ‘YES’… i would like Help to remain Awake!

Were you trying to use the identical logic people use for taking NyQuil to go to sleep, but with DayQuil to remain awake? First of all, that’s just plain a foul idea. you must never put any medications in your body that you simply don’t really want. If you are doing this, please stop taking NyQuil to assist yourself sleep. they create ZzzQuil now; refill on some, or any of the opposite sleep aids discussed above!

Hydration helps keep you alert

Most people have heard that you’re supposed to drink eight cups of water per day, but recent studies have shown we actually need more than that. according to the Mayo Clinic, women need eleven and a half cups of water per day, and men need fifteen and a half! More to the purpose, Healthline states that drinking enough water helps to stay you alert; dehydration can cause difficulty with concentration.

Have your caffeine boost earlier on in the day

Healthline also indicated it’s best to consume your caffeine at the start of the day for an energy boost, as having caffeine too late can cause issues with sleep. try and keep your total amount of caffeine for the day at 400mg or less though, as that’s what’s generally safe for many adults, per the Mayo Clinic. Four hundred milligrams is the equivalent of 4 brewed cups of coffee or ten cans of soda.

Now, please understand I’m not suggesting for a second that it might be at all healthy to consume that much of either, especially the soda, in a day; I’m just letting you understand what the healthy cap for caffeine reportedly is!

Snack healthy

Your attention and blood glucose will hold steady by eating healthy snacks throughout the day. you wish to seek out snacks that contain a mix of protein, carbohydrates, and healthy fats. Examples include peanut butter with whole wheat crackers, granola, yogurt, fruit, nuts, baby carrots, and cheese.

Sitting for long time can cause feelings of sleepiness. rise up and move when you’re feeling tired or needing an energy boost. according to one study completed by Robert Thayer, Ph.D., a ten-minute walk will increase energy for 2 hours. Interestingly, the short walk was compared to eating a candy, and people participants who ate the candy had a fast energy boost, but within an hour, felt more tired and had even less energy.

Light it up

Unfortunately, most indoor lights provide 100-1000 times less light than natural daylight, and since the majority of individuals spend 90% of their waking hours indoors, they’re not getting the necessary sunlight to feel alert and awake during the day time, according to Sunlight Inside. They recommend trying to induce 20-30 minutes of your time outdoors each morning to help boost your energy for the day. Healthline also suggests finding ways to increase the brightness in your environment as a technique to increase alertness.

Feel the beat

One final tip from Healthline is to play loud and energizing music. According to Science Alert, studies have found a variety of music types that this includes: sounds of nature, songs without lyrics, songs with an upbeat tempo, and songs played at a medium volume.

Additionally, there were two studies with conflicting results; one indicated you should listen to music you enjoy, while another suggested you should listen to music you’re ambivalent about, as music either strongly liked or disliked was too distracting. For this, I’d recommend being mindful about how these types of music are affecting you individually.
