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:
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 gmof caffeine could still be in your system.
To compound the caffeinated effect, if you drink anothercup of coffee at 2:00 PM as an afternoon pick-me-up, by Day 3 at 2:00 AM, nearly 90 gmof 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.
For good health, you’ve probably been told to eat more fiber — but all fibers are not alike. If you have risk factors for coronary artery disease and stroke, such as belly fat, diabetes, high cholesterol, or obesity, it’s a good idea to know the difference. Here’s how fiber in general can add years to your life.
Dietary fibers are found naturally in plants. They’re types of carbohydrates that don’t break down in your stomach and pass through your system pretty much intact. Fiber refers to carbohydrates, such as:
Fiber is separated into two main types: soluble fiber and insolublefiber.They’re different in how they react with water — and because of that, they have a different effect on your body.
Soluble Fiber – “The Cholesterol Sponge”
Soluble fiber dissolves in water and forms a viscous gel (soft and sticky) in the intestines which:
Helps lower LDL cholesterol* (the “bad” cholesterol). Soluble fiber soaks up cholesterol-laden bile in your intestine and eliminates them with other waste. Increasing fiber just 7 gm a day reduced stroke risk by 7% and heart disease risk by 9%.
Slows down digestion which helps control blood sugar and diabetes. Diabetes is a risk factor for heart disease.
Helps control body weight by making you feel full longer. It slows the emptying of food through the gastrointestinal tract. An additional 10 grams of soluble fiber per day reduced visceral fat by 4% over a 5-year period.
*LDL cholesterol is needed to produce hormones and provide structure to cell membranes, but because excesses can accumulate in the blood vessels and promote atherosclerosis, it’s been branded as the “bad” cholesterol.
Sources High in Soluble Fiber
Many foods have both soluble AND insoluble fibers with some having predominantly more of one than the other.
Oats, oat bran
Beans, split peas, lentils
Apples, avocados, pears, citrus fruits (but not fruit juices)
Insoluble Fiber – “Nature’s Broom”
Insoluble fiber acts like “nature’s broom”. It sweeps through your gastrointestinal tract and helps prevent constipation and colon cancer. Insoluble fiber does NOT dissolve in water, but absorbs water as it travels through your digestive tract which eases elimination, so it: Continue reading “KRON 4 | How Fiber Lengthens Your Life”→
Do you often wonder if you smell? Are you one who NEVER leaves home without a heavy coat of deodorant under your armpits? If so, take note…
The ABC’s of B.O.
Being conscious of your stink factor starts early on in middle school. This is when you sit through the prepubescent talks about the inevitable biological changes that will soon take place, such as emitting a new and rather objectionable body odor.
Companies have used these classroom lessons as an opportunity to promote their deodorants by providing product samples and coupons to preteens. But unless you’re told otherwise, you probably assumed these products are safe.
Here’s what you need to know about minimizing your unique essence, deciphering deodorant ingredients, and being a smart consumer.
How Chemicals Enter Your Body
Hair follicles (small ducts containing the hair shaft) and sweat pores are open entryways to chemicals. Areas of the body that are particularly hairy (e.g., the underarms) and have higher concentrations of sweat pores (e.g., under the arm) are most easily penetrable by chemicals.
Once chemicals enter the body and penetrate the deeper layer of the skin, they’re distributed via the bloodstream where they may exert their effects far from the original point of entry. Transdermal patches are effective because they deliver medication through the skin and into the bloodstream.
“Safe” Until Proven Toxic
Deodorants (classified as cosmetics) are considered safeonly until they’re proven toxic. Until a chemical is tested and evaluated for toxicity or if the results aren’t publicly available, current laws recognize the chemical as safe. Thousands of chemicals are considered “safe” because the government agencies cannot address the hazards associated with all of them. Continue reading “Is Deodorant Shortening Your Life?”→
Working with a team of physicists, Dr. Deborah Rhodes developed a new nuclear medicine technique for tumor detection called MBI (Molecular Breast Imaging). It’s three times as effective as traditional mammograms for women with dense breast tissue and uses a third the compression force.
The life-saving implications are stunning. So why haven’t we heard of it? Rhodes shares the story behind the tool’s creation, and the web of politics and economics that keep it from mainstream use.
Two weeks ago I had a biopsy and yesterday I found out I have cancer. Not pre-cancer… the real deal. Basal cell carcinoma. I’ve learned it’s one of the most common types of skin cancer, but knowing that I now join 2.2 million other Americans diagnosed each year doesn’t make my diagnosis any less daunting or serious.
I’m still dazed in disbelief. It’s not because I’m not a likely candidate. I admit it, I am. I grew up in the sun. As an active athletic kid, staying indoors was not an option. I can still hear my mom’s repeated warnings at the sight of my golden tan or raging sunburn, “You better stay out of the sun. You’ll get freckles. Worse yet, you’ll get skin cancer.” Well, once again, Mom was right.
As a youngster and young adult in my 20’s, I spent my summers on the tennis courts, by the pool, or on a boat or bike. Winters didn’t keep me from being a UV target either. I lived on the mountain and skied competitively, so in reality, I clocked in thousands of hours under the sun on the glorious slopes of Lake Tahoe.
What actually shocks me about the cancer diagnosis is the benign nature of the tumor. I’ve read the rules for skin cancer and examined the well publicized graphic photos, but my lesion doesn’t resemble any of the textbook examples. There is NO discoloration. It’s not brown, black or red. In fact, my doctor described it as “translucent”.
It’s one of those things I noticed while putting on my makeup some time ago. I casually thought about getting this small ‘bump’ removed someday, but considered such action as purely cosmetic and neither a big deal or urgent. However, during a routine head-to-toe skin cancer exam, my dermatologist regarded the bump as suspicious. Continue reading “Why I’m Now a Statistic… Protect Yourself Against Skin Cancer”→
