What Causes Your Body To Feel Tired – What causes fatigue after overthinking? To look for evidence of this, the study used magnetic resonance spectroscopy (MRS) to analyze brain chemistry throughout the work day.
Scientists have discovered new evidence that explains how intense thinking can make people more tired than sleepy.
What Causes Your Body To Feel Tired
Their research, published in the journal Current Biology, shows that after several hours of intense cognitive work, potentially harmful byproducts accumulate in an area of the brain known as the prefrontal cortex.

This, in turn, shifts your decision-making control so that when cognitive fatigue sets in, you switch to less costly actions that don’t require effort or waiting, the researchers explain.
“Influential theories suggest that fatigue is an illusion created by the brain to stop whatever we’re doing and switch to a more pleasurable activity,” said Mathias Pécillon of the University of Petit-Salpetriere in Paris, France. “But what we’re finding is that cognitive activity leads to real functional changes or toxic build-up, so fatigue may signal that we’re no longer working, but it has another purpose: to maintain the integrity of brain function.” :
The study’s first author, Antonius Wheeler, along with Pesilione and his colleagues, wanted to understand what mental fatigue is. While machines can calculate continuously, brains cannot. They wanted to find out why. They suspected that the reason was related to the need to process toxic substances caused by nervous activity.
To look for evidence of this, they used magnetic resonance spectroscopy (MRS) to analyze brain chemistry throughout the workday. They looked at two groups of people: those who had to think hard and those whose cognitive tasks were relatively easy.

They saw signs of fatigue, including reduced pupil dilation, only in the heavy-duty group. Even those in this group showed a shift toward options that offered less effort and short-term incentives. Importantly, they had more glutamate at synapses in the prefrontal cortex.
Along with previous evidence, the authors say, this supports the idea that glutamate accumulation makes further activation of the prefrontal cortex more expensive, so cognitive control becomes more difficult after a mentally demanding day.
So is there a way to limit our brain’s ability to think hard? “No, I’m afraid,” said Pesiglione. “I used the good old recipe of rest and sleep. There is good evidence that glutamate leaves the synapse during sleep.”

There may be other practical implications. For example, the researchers say, monitoring prefrontal metabolites can help identify severe mental fatigue. Such skills help adjust work plans to avoid burnout. He also advises to avoid making important decisions when tired.

In further research, they hope to discover why the prefrontal cortex is particularly sensitive to glutamate accumulation and fatigue. They wonder if the same symptoms of fatigue in the brain can be used to treat depression and cancer.

The Effects Of Sleep Apnea On The Body
If you’re always tired, the team at South Louisiana Medical Associates says you’re probably too busy to burn yourself out. Take a breath and see if that’s enough to make you feel like a new person; However, if you are constantly tired, there may be a medical reason.
If you’re always tired, don’t do it, says Sandra Adamson Freehofer, MD, an internist in Atlanta. Frihofer said
1. Anemia. Fatigue caused by anemia is caused by a lack of red blood cells, which carry oxygen from the lungs to tissues and cells. You may feel weak and short of breath. Anemia is caused by iron and vitamin deficiency, bleeding, internal bleeding and chronic diseases. Women of reproductive age are particularly susceptible to iron deficiency anemia.
2. Thyroid disease. When your thyroid hormones are out of whack, even your daily activities can kill you. The thyroid gland produces hormones that regulate metabolism. Excess thyroid hormone (hyperthyroidism) and accelerated metabolism. Too little (hypothyroidism), the metabolism slows down.

3. Diabetes. More than a million people are diagnosed with type 2 diabetes each year, but many may not even know they have it. Sugar, or glucose, is the fuel that keeps your body going. This is a problem for people with type 2 diabetes who cannot use glucose properly. People with diabetes often feel tired because they don’t have enough energy to keep their bodies functioning properly, says Christopher D.
4. Depression. Depression is a serious illness that affects our ability to sleep, eat and feel. Left untreated, depression symptoms can last for weeks, months, or even years. Common symptoms include decreased energy, changes in sleeping and eating patterns, problems with memory and concentration, hopelessness, worthlessness, and negative emotions.
5. Rheumatoid arthritis. an autoimmune disease, RA occurs when your immune system turns on itself and attacks healthy joint tissue. RA can sometimes permanently damage bones and cartilage. Other medical conditions, such as fibromyalgia and lupus, have many symptoms, including fatigue, decreased energy, loss of appetite, and joint pain.
6. Chronic fatigue. this condition causes severe fatigue that occurs quickly. People with chronic fatigue syndrome are too tired to engage in normal activities, and they tire easily with less effort. Other symptoms include headache, muscle and joint pain, weakness, swollen lymph nodes and inability to concentrate. Chronic fatigue syndrome has no known cause and is still poorly understood

7. Sleep apnea, a sleep disorder that causes you to wake up feeling tired, no matter how well you think you’ve rested. Sleep apnea is a brief interruption of breathing during sleep.

According to the American Academy of Sleep Medicine and the Society for Sleep Research, people ages 18 to 60 need 7 or more hours of sleep per night to improve their health.
Getting less than the recommended amount of sleep each day is not only associated with fatigue, poor performance, and an increased risk of accidents, but it also has negative health effects.
Reasons You Might Be Tired Often
If you’re struggling to get 7 hours of sleep, here are some tips to help you get some much-needed rest.
If you wake up tired despite the above sleep habits, it’s a good idea to see your healthcare provider to discuss whether you have a sleep-related health problem, such as insomnia, sleep apnea, or restless legs syndrome.
The easiest way to get rid of fatigue is to change your diet. A healthy, balanced diet can change the way you feel.
It’s important to choose healthy foods from the five food groups—fruits, vegetables, whole grains, protein, and dairy—to improve your health, get all the nutrients you need, and fight fatigue.
