Hot weather makes the body weak and tired? this is the cause!

If you go outside during the day when the sun is hot, you may feel tired and lethargic more quickly. However, why does being outdoors in hot weather make you tired and weak more quickly? 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 your body maintains your body temperature to stay cool and how can it make you tired easily? Here's the explanation.

Impaired blood flow

When the weather is hot, your body will make several adjustments to keep your body temperature optimal. For example, by dilating your blood vessels through a process known as vasodilation. This process allows a greater amount of blood to flow near the surface of the skin. Warm blood releases heat as it flows near the surface of the skin, causing the body temperature to drop. This increased amount of blood flow near the surface of the skin may explain why some people's bodies look redder when they are in hot temperatures.

In addition, it becomes difficult for your blood vessels to fill the chambers of your heart with blood. Because the heart doesn't fill with much blood, it can't send enough blood to all the other parts of your body.

One of the parts of the body that may lack blood because of it is the brain. Decreased blood flow to the brain can indeed make you weak and tired quickly. In fact, this can cause you to faint (lose consciousness).

Your body lacks fluids

Even if you don't do enough physical activity, room temperature or hot weather can quickly dehydrate or dehydrate your body.

This is because your body works hard to maintain body temperature and sweats a lot in hot temperatures. Dehydration on its own can make the body feel tired or weak.

Your body lacks salt and electrolytes

When you are dehydrated, if allowed to continue you can experience a lack 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, 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 allowed, you can experience heat exhaustion, a condition in which your body has overheated. This condition can get worse and progress to heat stroke or heat stroke which can be life threatening.

What to do in hot weather?

To prevent fatigue due to hot weather, avoid spending too long in the sun. Immediately find a place to take shelter if possible. Using a hat or umbrella can also help reduce exposure to direct sunlight on your body.

Drink plenty of water when you are in the sun and eat foods that contain salt to replace the salt and electrolytes that are lost when sweating.

In addition, try to balance your activity and rest. Try not to do too much physical activity in hot weather.

If you feel like you feel faint or drowsy in a room or in hot weather, you should immediately find a cool place and drink plenty of water.
