Do you have trouble falling asleep or staying asleep at night? If so, caffeine could be keeping you awake even though you never consume it at night. That’s because caffeine has a longer-lasting effect than you may think.
Negative Health Effects of Insomnia
Caffeine disrupts deep (restorative) sleep and the ability to fall asleep which cuts down on total sleep time resulting in:
- Overeating and binge eating
- Weight gain
- Increased mortality — According to a study by the American Cancer Society (Mortality Associated with Sleep Duration and Insomnia), insufficient sleep can shorten your life. Causes of death associated with sleep duration include heart disease, stroke, and breast/colon cancer.
Why Caffeine Has a Lasting Effect (Half-Life Explained)
Caffeine has a half life of five to six hours. In other words, it takes five to six hours for the amount of caffeine in your body to be reduced to exactly one-half of its concentration. (Translation: the amount of caffeine remaining in your body after six hours is equal to the amount you excrete.)
How It Breaks Down
The half-life of caffeine in a healthy adult is six hours. This does not take into consideration half-life variables (see below) that can influence how fast/slow a person metabolizes caffeine.
- Due to the half-life of caffeine, caffeine starts accumulating in your body when you consume it throughout the day. This could be in the form of another drink, food, or even medication.
- For example, if you drink two cups of coffee every day at 8:00 AM, by Day 3 at 2:00 AM nearly 45 gm of caffeine could still be in your system.
- To compound the caffeinated effect, if you drink another cup of coffee at 2:00 PM as an afternoon pick-me-up, by Day 3 at 2:00 AM, nearly 90 gm of caffeine could still be in your system. That’s nearly the amount of caffeine in a 16-oz Frappuccino® — a clue as to why you may not be able to sleep well.

The half-life of caffeine is not a fixed number and can vary based on the individual. Variables include your: Continue reading “KRON 4 | Why Caffeine Has Long-Lasting Effects”
VIDEO: You may think you’re one of the lucky ones who can eat unlimited bags of chips and other troves of salt; and yet, it doesn’t affect your blood pressure. But according to research published in the American College of Cardiology, excess sodium can adversely affect other target organs even if you don’t have hypertension.
Studies show elevated sodium levels can cause the inner lining of blood vessels (called the endothelium) to “malfunction”. The following occurs as a result:
- Vessels stiffen. Arteries that become less elastic and lose their contractility (ability to fully contract and relax) make it harder for the heart to pump blood throughout the body. Eventually, the heart wears out (heart failure).
- Vessels become sticky. Think of the lining of your blood vessels as being slick like Teflon. An unhealthy endothelium is sticky like Velcro and causes plaque to attach. Plaque builds up in the brain too — leading to Alzheimer’s.
- The body breeds dangerous inflammation. Inflammation may cause plaque inside blood vessels to crack, rupture, and dislodge from arterial walls. The body responds like with any other injury by causing blood to clot. Clots clog up vessel freeways and block blood flow to the heart (heart attack) or brain (stroke). Inflammation is also the key reason behind why heart attacks are more likely to occur after getting the flu.
NOTE: Eating too much sugar can have the same effect on the endothelium as an excessive intake of sodium.
Research found that elevated sodium levels may increase the wall thickness of the heart’s main pumping chamber (left ventricle). This thickening can lead to cardiac issues, such as:
- Arrhythmia (abnormal heart rhythm)
- Heart attack
- Sudden cardiac arrest (sudden loss of heart function)
- Heart failure (inability of the heart to pump enough blood throughout the body)
High blood pressure is a major risk factor for this muscle tissue enlargement, but it was also found in healthy people with NORMAL blood pressure who consumed high amounts of sodium.
Healthy kidneys remove extra fluid and waste from the blood. Studies found that a high Continue reading “KRON 4 | Salt Affects More Than Blood Pressure”

Untreated hypertension (high blood pressure) is the underlying cause of several life-threatening health conditions which can affect your heart, kidneys and other vital organs. It is known as the “silent killer” because there are often no warning signs or symptoms. Learn how your blood pressure can affect your eyes. (TRT: 01:01)
