When You Are Tired Your Brain Shrinks

12 Reasons Why You Feel Tired All The Time and How To Fix it in 2020 from www.pinterest.com

Why Does This Happen?

Tiredness has a lot of physical effects on the body and mind, but did you know that it can also cause your brain to shrink? Researchers have found that when we’re exhausted, our brains can actually shrink in size. This isn’t permanent, however, and the brain will return to its regular size when rested. So why does this happen?

The answer lies in the fact that our brains are made up of mostly water. When we’re tired, our bodies become dehydrated, which leads to a decrease in the amount of water in our brains. This causes the brain to shrink temporarily, which can have a number of consequences. For example, it can lead to difficulty concentrating, slowed reaction times, and problems with memory.

It’s important to recognize the signs of tiredness, as well as the risks associated with it. If you’re feeling exhausted, you should make sure to get plenty of rest and hydrate to ensure that your brain doesn’t shrink any further.

What Are The Symptoms Of Tiredness?

The most obvious symptom of tiredness is fatigue. You may feel lethargic and have a hard time getting out of bed in the morning. Other symptoms include difficulty concentrating, difficulty remembering things, irritability, and a decreased ability to react quickly. You may also find yourself yawning more often than usual.

If you’re experiencing any of these symptoms, it’s important to take action. Make sure that you’re getting enough rest and staying hydrated. You should also limit your caffeine and alcohol consumption, as these can exacerbate the effects of tiredness.

It’s also important to take breaks throughout the day, especially if you’re working long hours. Taking a few minutes to relax can help to refresh your mind and body and make it easier to stay focused.

What Are The Long-Term Effects Of Tiredness?

The short-term effects of tiredness are well-known, but what about the long-term effects? The good news is that the effects of tiredness are usually reversible. However, if you’re chronically tired, it can take a toll on your health.

Chronic tiredness can lead to an increased risk of developing certain health conditions. For example, it can increase your risk of developing high blood pressure, diabetes, heart disease, and depression. It can also lead to a weakened immune system, making you more susceptible to infections.

Additionally, if you’re feeling constantly tired, it can affect your work performance. Lack of sleep can lead to poor concentration and decreased productivity. This can have a negative impact on your career and can even lead to job loss.

Tips For Getting Better Sleep

If you’re having trouble getting enough sleep, there are a few things you can do to help. First, make sure that you’re getting enough exercise. Exercise helps to tire out the body and can make it easier to fall asleep at night.

You should also avoid caffeine and alcohol before bed. Both of these can affect your sleep cycle and make it harder to get the rest you need. Additionally, make sure that your bedroom is a comfortable temperature and free of distractions. You may also want to invest in a white noise machine or eye mask to help you sleep better.

Finally, try to go to bed and wake up at the same time every day. This can help to regulate your sleep cycle and make it easier to get quality sleep.


Tiredness can cause the brain to shrink temporarily, leading to a number of consequences. It’s important to recognize the signs of tiredness and take steps to get better rest. Exercise, avoiding caffeine and alcohol before bed, and going to bed and waking up at the same time every day can all help to improve your sleep quality.

If you’re feeling chronically tired and it’s having a negative impact on your life, it’s important to talk to your doctor. They may be able to recommend treatments or lifestyle changes that can help to improve your sleep and overall health.
