How Long Can You Live Without Water?

Views:240     Author:Site Editor     Publish Time: 2021-04-12      Origin:Site

The human body needs a lot of water to function correctly, and a person may only survive a few days without water. Many other factors, such as a person’s activity levels and their environment, also play an essential role, so there is no reliable way to tell how quickly someone would die from dehydration.

 

Dehydration happens quickly, causing extreme thirst, fatigue, and organ failure and death ultimately. A person may go from feeling thirsty and slightly sluggish on the first day with no water to having organ failure by the third day.

 

Dehydration does not affect everyone in the same way. Each person will have a different tolerance level to dehydration and may be able to survive without water for longer or shorter periods than someone else.

 

 

How Long Can You Live Without Water?

On average, a person can survive without water for about 3 days, but some have reported to survive around 8 to 10 days.

 

The survival time can also be stretched and contracted by external factors, such as temperature, humidity and the health of the people. For instance, athletes exercising intensely in the dry heat can dehydrate and die within hours. Whereas, the record holder for surviving the longest without water survived for 18 days after he was put in a jail and forgotten for over two weeks!

 

However, it is reasonable to point out that he was indoors in the absence of the sun or any heat.

 

Also, one can live without water indefinitely if you have eaten enough water-containing foods to replace the lost water. Our body doesn’t necessarily need “pure water, it only requires electrolytes and nutrients in aqueous solution.

Poon Lim, a Chinese sailor whose ship sank in 1942, survived 133 days on a raft in the open ocean. He ran out of supplies in the first month, leaving him 3 months without a drop of fresh water! So how did he survive? He caught and ate fish and drank seagull or shark blood. However repulsive, it kept him alive.

 

So we can clearly know that we can’t survive without water for very long, but the exact amount of time we can live without water varies. This is because certain factors contribute to our body’s use of water, including: 

our environmental conditions

activity level

age

health

weight

sex

food intake

2. Effects of Having No Water

Without water, the body is unable to function correctly and will begin to stop working.

 

The effects of dehydration come on quickly, especially in extremely hot conditions when a person sweats.

 

The body uses water to produce sweat, which evaporates and lowers a person’s body temperature. Without water, the body cannot produce sweat. This can lead to a dangerous increase in body temperature and put pressure on the fluid in the body, including the blood.

 

If this leads to a drop in blood volume, less blood circulates in the body, causing a severe drop in blood pressure, which can lead to unconsciousness or death. At the same time, the mouth dries, and the digestive system slows down.

 

Therefore, it is necessary to keep the body properly hydrated to avoid a series of damages caused by dehydration.

 

In summary, water is very important for our survival. Under conditions, we must drink enough water, and at the same time, we must ensure the safety of the drinking water. We can use simple water purification methods to purify our drinking water, such as boiling. We can also use professional water treatment devices for water treatment, such as ozone water purifiers, ozone water sterilizers, etc.

 

Our company is committed to producing ozone water filters, ozone kitchen water purifiers, reverse osmosis water purifiers, etc. If you are interested, please contact us.
