Medical Video: Why Are You Always Tired?
If you travel outside the house during the day when the sun is hot, You may feel tired and lethargic faster. However, why is being outdoors with hot weather makes you tired and weaker faster? The reason is simple, namely because in hot weather, your body will be forced to work harder to maintain your body temperature.
What is the way the body maintains body temperature to stay cool and how can it make you easily tired? Here's the explanation.
Blood flow is interrupted
When the weather is hot, your body will make several adjustments to keep your body temperature optimal. For example by widening your blood vessels through a process known as vasodilation. This process allows more amount of blood to flow near the surface of the skin. Warm blood releases heat when it flows near the surface of the skin, so that body temperature will decrease. This increase in the amount of blood flow near the surface of the skin can explain why some people's bodies look redder when they are in hot temperatures.
In addition, your blood vessels have difficulty filling the heart chambers with blood. Because the heart is not filled with blood, the heart cannot send enough blood to all of your other limbs.
One of the limbs that may lack blood is therefore the brain. Decreasing blood flow to the brain can indeed make you weak and tired quickly. Even this can cause you fainted (loss of consciousness).
Your body lacks fluids
Even if you do not do physical activity that is heavy enough, room temperature or hot weather can quickly make your body lack of fluids or dehydration.
This is because your body works hard to maintain body temperature and sweat a lot in hot temperatures. Dehydration alone can make the body feel tired or powerless.
Your body lacks salt and electrolytes
When you lack fluids, if you leave them continuously you can experience a shortage of salt (sodium) and electrolytes. This is especially true when you replace body fluids with drinks that replace fluids, but do not replace electrolytes.
The problem is that salt and electrolytes are needed by the body to maintain fluid balance in the body. So if you drink water but don't replace electrolytes, your body fluids will immediately be wasted again. Either through sweat or urine (urine).
If the above events are left, you can experience heat exhaustion, a condition where your body has overheated. This condition can worsen and continue to become heat stroke or heat stings that can be life threatening.
What to do when it's hot?
To prevent fatigue due to hot weather, avoid spending too long in the sun. Immediately find a place to shelter if possible. Using a hat or umbrella can also help reduce sun exposure directly on your body.
Drink plenty of water when you are in the sun and eat foods that contain salt to replace salt and electrolytes that are lost when sweating.
Also, try to balance your activities and rest. Try not to do physical activity that is too heavy when the weather is hot.
If you feel like you want to faint or get sleepy while in the room or hot weather, you should immediately take shelter to a cool place and drink lots of water.
