"The groundwork of all happiness is health." - Leigh Hunt

Trouble remembering information? Could be sleep, mood – or age.

You are going to the market. You must take eggs, cheese, milk, bread, tomatoes, carrots and string beans. Can you remember these items by repeating them to yourself? You arrive at your usual market, nevertheless it is unexpectedly closed. A passer-by gives you verbal directions to the brand new market. Can you imagine the trail together with your eyes closed? Both activities tap working memory—that's, your memory for information that it is advisable actively keep “in mind” and steadily manipulate.

We use any such memory each day. For example, once we're comparing two or more options—whether dinner entrees, health plans, or mutual funds—we're using our working memory to be mindful the main points of the various options.

The frontal lobes direct the components of working memory.

The two frontal lobes of the brain play a crucial role in certain varieties of memory. Working memory is usually divided into two components, plus an executive system that shifts attention between them. One component helps you keep verbal information in your head by repeating it silently to yourself. Another component processes spatial information, reminiscent of mentally planning the route you'll take to avoid rush hour traffic.

Virtually all tasks that involve working memory activate the prefrontal cortex, the a part of your frontal lobes just behind your brow. When you're repeating verbal information to yourself, the left hemisphere of your brain is more involved. When you're mentally following a path, the correct hemisphere is more involved. Interestingly, as working memory tasks became tougher, each hemispheres improved no matter whether the duty was verbal or spatial.

New research shows that sleep and mood affect working memory.

Recently, researchers from California and Michigan did A pair of studies To understand the consequences of sleep, mood and age on working memory. Two facets of those studies are novel. First, although each of those effects has previously been checked out individually, this study examined their combined effects and the way they interact with one another. Second, the researchers examined a community sample of adults ages 21 to 77.

The first study found that poor sleep quality and depressed mood each independently reduced working memory capability – the variety of things that will be held in mind. A second study confirmed the sooner findings. He also found that older age reduced the accuracy of working memory – the main points of every item, reminiscent of whether the cheese it is advisable pick up is Swiss or cheddar.

May help improve mood.

The implications of this research are clear. While we will't stop aging, we will work to enhance our sleep quality and mood. Depressed mood will be brought on by external life events (reminiscent of retirement, a brand new diagnosis, or the death of a friend) or biological aspects (reminiscent of changes in our brain chemistry). Regardless of the explanation, Depression can be treated with medication or talk therapy.. Studies show that combining these methods provides the best profit. Not fascinated with taking medication or talking to someone about your mood? Aerobic exercise, meditation, and leisure therapy have each been shown to enhance mood.

Better sleep can improve working memory.

Poor sleep quality will be brought on by a sleep problem, reminiscent of obstructive sleep apnea (not getting enough oxygen during sleep). Or, it might be secondary to a medical problem, reminiscent of heart failure.

Sleep disturbances may occur because of this of habits, reminiscent of engaging in waking activities in bed. Sleep experts note that the sensation of being in bed signals the body that it's time to sleep. It is best to make use of your bed just for sleeping and sexual intercourse. If you spend hours in bed talking on the phone, eating, or doing other activities, you're sending your body the fallacious signal in regards to the purpose of being in bed. Learning about healthy sleep habits may help.

People may fall into a foul sleep cycle by repeatedly staying up too late at night or sleeping too late within the morning. Most people need about eight hours of sleep each night, with the typical range being between seven and nine. Many people think that they need more sleep as they grow old, but this is definitely not true. On average, older adults need just as much sleep as they did once they were younger — or perhaps half-hour less. If you sleep an excessive amount of at some point, you'll often have trouble sleeping the subsequent night.

The bottom line

If we improve our mood and the standard of our sleep, we will improve our working memory—our ability to do things in our brain.
