Can a Low Body Temperature Be Caused By Dehydration

Can a Low Body Temperature Be Caused By Dehydration?

Drinking plenty of fluids is vital, especially in the summer when dehydration is more prone to occur. But did you know that the body temperature can be affected due to dehydration? We’ll learn the connection between dehydration and body temperature in this blog article and offer some advice on how to stay hydrated.

What Is Dehydration?

When someone loses more fluid than they consume, dehydration sets in. Water is necessary for human life because it makes up two thirds of the human body. Water actually has a big impact on how the body works normally, helping with digestion, lubricating the joints, and getting rid of toxins to maintain good skin.

Types of Dehydration

According to healthdirect, they differentiate the signs and symptoms of mild to moderate dehydration from severe dehydration. Here are the signs and symptoms.

If you have mild to moderate dehydration, you might:

  • be thirsty
  • have a dry mouth, lips and tongue
  • have a headache
  • have dark yellow urine
  • be dizzy or light-headed, particularly when standing up

Severe dehydration is life-threatening and needs immediate attention. If you have severe dehydration, you might:

  • be extremely thirsty
  • have a very dry mouth
  • be breathing fast (Tachypnea)
  • have a weak, rapid heart rate
  • low blood pressure
  • have a fever
  • have little or no urine
  • be irritable, drowsy or confused
  • Cold clammy skin (wet)
  • Loss of consciousness

Causes of Dehydration

Here are the usual reasons why people get dehydrated:

  • after strenuous exercise, especially in hot weather
  • after severe vomiting or diarrhoea
  • with a fever
  • after drinking too much alcohol
  • while taking certain medicines such as diuretics
  • as a complication of diabetes
  • if they don’t drink enough water
  • Anyone may become dehydrated, but babies, young children, older adults and people with long-term illnesses are at most risk.

People at Risk of Dehydration

Not only people who are exposed to the sun directly are at risk for dehydration. In fact, among the sportsmen who frequently experience the disease are bodybuilders and swimmers. As strange as it may seem, you can perspire while swimming. Swimming causes swimmers to sweat a lot.

Dehydration is more likely to affect some persons than others, including:

  • people working outdoors who are exposed to excessive amounts of heat (welders, landscapers, construction workers, and mechanics)
  • older adults
  • people with chronic conditions
  • athletes (especially runners, cyclists, and soccer players)
  • infants and young children
  • people who reside in high altitudes

Children and older adults should receive immediate treatment, even if they’re experiencing symptoms of mild dehydration.

Seek immediate medical attention if anyone of any age group exhibits any of the following symptoms:

  • severe diarrhoea
  • blood in the stool
  • diarrhoea for 3 or more days
  • inability to keep fluids down
  • disorientation

Treatment of Dehydration

According to Mayo Clinic, the only effective treatment for dehydration is to replace lost fluids and lost electrolytes. The best approach to dehydration treatment depends on age, the severity of dehydration and its cause.

Use an over-the-counter oral rehydration solution for infants and kids who have been dehydrated due to diarrhoea, vomiting, or fever. These solutions restore fluids and electrolytes by combining water and salt in a precise ratio.

Every one to five minutes, start with roughly a teaspoon (5 millilitres) and gradually increase as tolerated. For very young children, using a syringe could be simpler. Sports drinks might be diluted for older kids. Mix 1 part water with 1 part sports drink.

The majority of individuals who experience mild to moderate dehydration due to diarrhoea, vomiting, or fever can get better by consuming more water or other liquids. Full-strength fruit juice and soft beverages may make diarrhoea worse.

If you work or exercise outdoors during hot or humid weather, cool water is your best bet. Electrolyte- and carbohydrate-containing sports drinks may also be beneficial.

Severely dehydrated children and adults should receive medical attention from emergency workers who arrive in an ambulance or in a hospital emergency department. Intravenously administered salts and fluids have a quick absorption rate and hasten healing.

Prevention of Dehydration

According to EVERYDAYHEALTH, here are the ways to prevent dehydration: 

  1. Pay attention to the possible symptoms of dehydration.
  2. Respond to thirst when the feeling strikes.
  3. Check your urine colour for signs that you’re dehydrated.
  4. Assess the inside of your mouth for dehydration symptoms.
  5. Be sure to increase your intake when exercising.
  6. Drink more water when you’re sick or in hot weather.
  7. Know if you’re in a high-risk group for dehydration.

It is unclear exactly how low body temperature and dehydration are related. Dehydration, on the other hand, is thought to make your body lose heat more quickly. Body temperature may decline as a result of this. Dehydration might also make it harder for your body to control its own temperature. This implies that you could experience chilly even though the environment around you is warm. You should get medical help right away if you suspect that you may be dehydrated. Dehydration should not be handled lightly. Please get medical help as soon as you can if you experience any of the symptoms mentioned above. We are grateful for your time in reading this blog.
