Each morning, the alarm goes off, and another battle in the never-ending war against drowsiness begins. For Americans, their main defense against a foggy mind is caffeine, with as much as 85 percent of the adult population drinking at least one caffeinated beverage each day. But you’ll be relieved to learn there are other foods and beverages besides coffee (and caffeinated energy drinks) that can help us feel alert.
Staying alert is not simply a proverbial “state of mind”— it’s literal one. The physiological reactions happening in your brain determine your ability to focus and stay awake. Normally, when the brain is active, it burns energy transported by the neurotransmitter called adenosine triphosphate (ATP). The constant degradation of ATP produces just plain adenosine, and when enough adenosine accumulates, it triggers the need to sleep and renew your energy source. The caffeine is affective at keeping us awake because it actually binds to and blocks the brain’s adenosine receptors, delaying the feeling of drowsiness.
Researchers have shown that tiny iron particles, injected into the brain and carried to target regions using antibodies, can attach themselves to cells and activate them when manipulated by magnets.
This means that there could be a non-invasive method for stimulating the brain. And scientists hope it could revolutionize the treatment of Parkinson’s – and eventually other neurological and psychological conditions.
Parkinson’s disease is a progressive neurological condition that affects more than 10,00,000 people in India, often leading to disabling symptoms.
Dengue fever is spreading out in the country.Experts suggest natural methods like neem and coconut oil concoction or garlic to keep the mosquito-borne tropical disease at bay.
Neem oil acts as a great indoor mosquito-repellent owing to its smell that wards off mosquitoes. One can make an effective insecticide by mixing neem oil and coconut oil in equal proportion and rub it on the exposed parts of a body.
Another natural method to keep mosquitoes at bay is to plant Tulsi near the window panes. The plant has properties that do not allow mosquitoes to breed.
Eating well has many known benefits. But a good diet may not be able to counteract all the ill effects of stress on our bodies.
A new study, published in Molecular Psychiatry, suggests stress can override the benefits of making better food choices.
To evaluate the interactions between diet and stress, researchers recruited 58 women who completed surveys to assess the kinds of stress they were experiencing. The women also participated in what researchers call a “meal challenge,” where they were each given two different types of meals to eat, on different days.
Contrary to popular belief, a new study suggests taking longer breaks between sets of weightlifting may promote muscle growth.
The research reveals that men who had longer rest periods between four weightlifting sets showed a significant increase in muscle rebuilding activity – a process that aids muscle growth – compared with those who had shorter rest periods.
Study co-author Dr. Leigh Breen, from the University of Birmingham in the United Kingdom, and colleagues recently published their findings in the journal Experimental Physiology.
Although abstinence from alcohol is widely recommended when trying to become pregnant, its exact implications for a woman’s fertility are not known. A new study published in The BMJ charts the interaction in new detail.
An estimated 24 percent of couples in developed countries take more than 12 months to conceive.
Because drinking alcohol is a pervasive part of modern life, its impact on fertility is of great interest.
An estimated 18.2 percent of American women aged 18-44 engage in binge drinking (more than four drinks in one sitting), three times per month.
If you don’t have the time to fit in a full yoga practice, here are 5 yoga poses you can squeeze into your day.
Here are five yoga poses you can easily bring into your day while going about your regular activities. Of course, you may think, why not just practice a yoga class? Well, sometimes it just doesn’t work out because:
you feel you have no spare time at all
the spare time you do have is spent on something else – another discipline, meditation, Pranayama, running…
you’re too tired to make the effort to unroll your mat and do a proper practice
you simply just don’t feel like it
Maybe you can come up with a few reasons yourself!
According to a handful of recent studies, okra may reduce symptoms of diabetes – a group of diseases that includes type 1 diabetes, type 2 diabetes, and gestational diabetes.
Diabetes claimed the lives of 75,578 Americans in 2013, according to the United States Centers for Disease Control and Prevention (CDC). In 2014, 8.5 percent of adults worldwide had the condition, the World Health Organization (WHO) report. By 2030, diabetes may be the seventh leading cause of death.
A number of factors increase a person’s risk of developing diabetes, including a family history of the disease. Lifestyle factors also play a role, so doctors routinely recommend diet changes and increased exercise to reduce blood sugar levels.
Star Trek fans will be familiar with the tricorder – a device used in the fictional TV series to scan and gather detailed information about places and living things. Now, researchers have brought the technology to the real world, creating a wearable, tricorder-like device that can measure biochemical and electrical signals in the human body simultaneously.
The device – called the “Chem-Phys patch” – measures real-time levels of lactate, a biochemical that serves as an indicator of physical activity, as well as the heart’s electrical activity.
Put simply, the novel technology monitors a person’s fitness levels and heart function at the same time, and it is the first device that can do so.
“One of the overarching goals of our research is to build a wearable tricorder-like device that can measure simultaneously a whole suite of chemical, physical and electrophysiological signals continuously throughout the day,” says co-project leader Patrick Mercier, of the Jacobs School of Engineering at the University of California-San Diego.
