There are several different ways that dayquil can affect your heart rate. The ingredients in the product can be to blame, but it’s generally thought to be due to the way it affects the blood flow to your heart.
Dayquil is a popular nighttime sleep aid. Although it’s not generally associated with an increased heart rate, it’s still possible that it could cause one.
Dayquil contains dimethicone, which is a silicone-based substance. This substance is known to cause a buildup of fluid in the lungs that can lead to asthma attacks.
Additionally, the dimethicone in dayquil is very irritating to the lungs. This can lead to breathing difficulties and a potentially life-threatening condition called pulmonary edema, which is swelling of the lungs.
Some people who use dayquil may also develop a condition called Raynaud’s phenomenon. This is when the body stops responding to cold due to a reduction in the volume of blood flow to the skin and other tissues. This condition is often accompanied by a sudden reduction in blood flow to the hands.
As you can imagine, this can lead to painful, itchy, and red fingers and toes. Raynaud’s phenomenon is much more common in women than in men.
Does caffeine affect heart rate?
Caffeine is well known for affecting a person’s heart rate by stimulating the sympathetic nervous system. This is the part of the nervous system that increases the heart rate when you’re anxious or excited.
However, it’s not clear exactly how caffeine affects your heart rate. It’s thought that the caffeine directly affects the heart by increasing blood pressure.
Caffeine is also known to cause a temporary heart attack in some people who take it typically those who suffer from heart disease or other forms of heart disease.
Caffeine can also cause changes to the heart rhythm. This can lead to an irregular heartbeat.
Although many people claim that caffeine causes a heart rate increase, there’s currently no scientific evidence to support this.
Is it safe to use caffeine before bedtime?
Although caffeine is generally safe to consume at any time of day, it’s not recommended to use caffeine just before bedtime. This is because caffeine is known to increase heart rate and temporarily affect the heart more than usual when you’re stressed and anxious.
Additionally, caffeine may cause a heart attack. If you take caffeine before bedtime, this could be life threatening. It’s important to discuss this with your doctor before beginning any new regimen.
What about other products that contain caffeine?
Although it’s not the most common cause of heart rate increase, caffeine is still a possible cause for your heart rate to increase. This is because caffeine can stimulate your nervous system and affect your heart rate.
Other products that contain caffeine include:
- Caffeine pills
Caffeine-free energy drinks
Energy drinks with caffeine
Sour candies with caffeine
Coffee-flavored chewing gum
Caffeinated chewing gum
Caffeinated breath freshener
Caffeine pills and coffee capsules are often mixed together with the other ingredients in the product. If this is the case, it’s important to read the ingredients label carefully.
There may be caffeine that’s been hidden in the pills or capsules. Be aware that caffeine is a stimulant and can have a negative effect on your heart rate.
If you have questions about whether caffeine is safe to take with heart medications or heart medications are causing your heart rate to increase, you should speak to your doctor.
When to see a doctor?
There are a few reasons why you should see your doctor if you have a heart rate increase after using caffeine. The first is if you experience symptoms of a heart attack.
Heart attack symptoms include:
- Chest pain
- Shortness of breath
Heart attack symptoms are often followed by a heart rate increase. If you experience these symptoms, you should seek immediate medical attention.
The second reason to see a doctor is if you notice a change to your heart rate. This can be due to caffeine, a product that contains caffeine, or another underlying condition.
These reasons include:
- Heart conditions such as coronary artery disease
- Heart conditions like high blood pressure
- High blood sugar levels
- Caffeine withdrawal
- Substance abuse
How is it diagnosed?
If you notice a heart rate increase, you should make an appointment with your doctor to discuss your symptoms and other factors that could be causing them.
Your doctor will likely order a blood test to check for heart conditions. This can include an electrocardiogram (ECG or EKG), an echocardiogram, and a stress test.
A stress test is a series of tests that evaluate your heart rate and blood pressure throughout the day and night, and the results are compared to normal values.
How is it treated?
The first step in treating your heart rate increase is to identify the underlying cause. If caffeine is causing your heart rate to increase, you can talk to your doctor about using an alternative product.
If you’re using a product that contains caffeine, this can include caffeine pills, caffeine capsules, or both.
If your heart rate increase is due to a product that doesn’t contain caffeine, you can talk to your doctor about switching to a product that doesn’t contain caffeine.
If you’re using caffeine pills or caffeine capsules, you can discuss the following options with your doctor:
- Taking the pill with food
- Taking the pill after bedtime
- Using a caffeine withdrawal treatment
If you stop using caffeine, it may take several weeks for your heart rate to return to normal. It may take longer if you used caffeine for a long time or regularly.
If you’ve been using caffeine for a long time or regularly, you should work with your doctor to come up with a plan that’s right for you.
What’s the outlook?
Caffeine is a known stimulant that can temporarily increase heart rate. However, there’s currently no evidence to suggest that caffeine causes a heart rate increase.
If you’re experiencing heart rate increases as a result of caffeine or another substance, you should always speak to your doctor.
This is especially important if you’re using medications to treat your heart conditions.
