V sridharan while reporting the Dos and Don'ts on hot summer, which I received
4 hours ago 1 20AM 17th May2023 IST // 12 50 PM 16/5/23 in USA , I just heard
SUN TV yesterday news reporting 107 at Chennai and 115 at Arakkonam on 16th in
India. In the USA it is 82 only but because we are angular on the earth it is
as bad as 104 at chennai. Heat waves in this season are inevitable. Elders aged
must carefully watch, showing your head outside.
It is possible to reduce body heat externally or internally. Jumping into a
cool pool is an example of external cooling while drinking cold water helps
reduce body temperature internally.
Experts consider the normal body temperature to be around 98.6ºFTrusted Source
(37ºC), but it can vary by up to 0.9ºF (0.5ºC) depending on the time of day. It
also differs slightly from person to person.
There are many reasons why a person’s body temperature may rise. These include
illnesses, medications, and intense physical activity. A body temperature above
100.4ºFTrusted Source (38ºC) usually indicates fever.
Simply being outdoors on an extremely hot day can be enough to cause heat
exhaustion or heat stroke. This is of particular concern around the world with
the growing impact of rising temperatures due to climate change.
According to the National Oceanic and Atmospheric Administration (NOAA)’s 2021
Annual Climate Report, the combined land and sea temperature has been rising at
an average rate of 0.14 degrees Fahrenheit (ºF ) or 0.08 degrees Celsius (ºC)
per decade for nearly 150 years.
At the same time, a 2021 study estimates that 37%Trusted Source of all
heat-related deaths around the world can be attributed to climate change.
Body temperature rises when the external temperature increases but also when
the internal temperature increases. The human body is always regulating its
temperature, and it can lower it in four different waysTrusted Source:
- vaporization, which it achieves by sweating
- radiation, which means releasing heat into the surrounding air
- convection, which occurs when cooler air surrounds the body
- conduction, which is the transferral of body heat into adjacent cold water
or ice
A brain region called the hypothalamus is responsible for regulating body
temperature. It checks the body’s current temperature against its normal
temperature and then regulates it.
When the body is too hot, regulation occurs through sweating to cool it down.
When it is too cold, the hypothalamus triggers shivering to warm it up.
Although it may seem counterintuitive, eating spicy foods and engaging in
activities that cause the body to sweat could make it feel cooler compared to
the outside temperature. This is because sweating reduces body temperature.
Tips to reduce body temperature
A brain region called the hypothalamus is responsible for regulating body
temperature. It checks the body’s current temperature against its normal
temperature and then regulates it.
When the body is too hot, regulation occurs through sweating to cool it down.
When it is too cold, the hypothalamus triggers shivering to warm it up.
Although it may seem counterintuitive, eating spicy foods and engaging in
activities that cause the body to sweat could make it feel cooler compared to
the outside temperature. This is because sweating reduces body temperature.
Below are eight tips for reducing body heat:
1. Drink cool liquids
Drinking cool liquids like water or iced tea can help reduce body temperature
by cooling the body internally. The regular intake of fluids can also prevent
dehydration, which can increase body heat.
2. Go somewhere with cooler air
People can reduce their body temperature by movingTrusted Source to an area
with a cooler external temperature. The body will lose heat by convection.
3. Get in cool water
Swimming in cool water, taking a lukewarm bath, or applyingTrusted Source cold
water to the body can reduce body temperature. In these cases, body temperature
will decrease as a result of conduction.
4. Apply cold to key points on the body
Applying cold water or iceTrusted Source to strategic points on the body where
the veins are close to the surface — such as the wrists, neck, chest, and
temples — can quickly lower the temperature of the blood running through these
veins. This allows the body to feel cooler.
5. Move less
The body releases heat when it moves. In hot temperatures, a person is likely
to feel less hot if they avoid heavy exercise and limit their movement.
6. Wear lighter, more breathable clothing
Heat passes more easily through some fabrics than others. Natural fabrics, such
as cotton and linen, allow heat to escape from the body more easily than
synthetic fabrics, such as acrylic and nylon.
7. Take heat regulating supplements
Depending on the cause of high body temperature, taking a supplement may help
regulate body heat.
A 2018 studyTrusted Source that compared plant extracts found that evening
primrose oil and black cohosh effectively reduced the frequency and severity of
hot flashes in people going through perimenopause or menopause.
Black cohosh also reduced the frequency of hot flashes.
8. Talk to a doctor about thyroid health
At times, high body heat may be due to an overactive thyroid. When this is the
case, a person might alsoTrusted Source notice other symptoms, such as a rapid
heart rate, sweating, jaundice, and confusion.
Hot environment
Spending time outside in very hot weather can increase a person’s body
temperature, as can being in a hot indoor environment for extended periods.
Wearing too many layers in either situation can also lead to an increase in
body temperature.
Overexposure to sun or heat
Spending too much time in the sun can increase body heat or even lead to
heatstroke, which some people call sunstroke.
Children and older adults are particularly at risk of heatstroke. Dehydration
from too much sun exposure can further increase body heat. Therefore, drinking
lots of fluids and resting after prolonged sun or heat exposure is important.
What are the signs of being overheated?
Doctors categorize overexposure to heat into three levelsTrusted Source: heat
cramp, heat exhaustion, and heatstroke.
Although hard on the body, heat cramp does not require medical attention. It
tends to subside with plenty of rest and rehydration.
The symptoms of heat cramp include:
- high body temperature
- dizziness
- muscle pain or stiffness
Heat exhaustion requires medical attention if the symptoms last longer than an
hour or worsen over time.
In addition to the symptoms of heat cramp, a person may experience:
- vomiting
- headaches
- reduced concentration or impaired judgment
Heatstroke is very serious and requires medical attention at a hospital.
The symptoms of heatstroke include the symptoms of heat cramps, as well as:
- seizures
- difficulty maintaining consciousness
- liver failure
Exercising or moving more than usual
When a person moves, they create energy. Heat is the body’s way of releasing
energy. But too much physical endurance can createTrusted Source too much body
heat. To reduce body heat, a person can try temporarily moving less or only
when necessary.
Perimenopause or menopause
During perimenopause and menopause, people often experience hot flashes and
night sweats, which temporarily elevateTrusted Source body temperature.
Medications, hormones, and recreational drugs
Medications and other drugs can raise a person’s body temperature by affecting
heat loss or production.
These include:
- diuretics
- anticholinergics
- Beta-blockers
- neuroleptic drugs
- inhaled anesthetics
- succinylcholine
These medications either impairTrusted Source the body’s ability to lose heat
by sweating or decrease the body’s ability to get rid of excess heat.
Some medications, hormones, and recreational drugs can also cause the body to
produce excess heat because they increase the metabolic rate. These
includeTrusted Source drugs like MDMA and cocaine.
Being unwell
Body temperature also increases in response to germs such as viruses and
bacteria. An increased body temperature helps the body fight off invading
illnesses, which is why a fever is often a sign of getting sick.
Thyroid storm
A thyroid storm is an excess of thyroid hormone in the body. It is a life
threatening condition that requires immediate medical attention. A thyroid
storm may occur after illness, surgery, infection, or pregnancy.
As well as a very high body temperature, symptoms of a thyroid storm
includeTrusted Source:
- rapid heartbeat
- sweating
- nausea or vomiting
- agitation
- jaundice
- abdominal pain
Malignant hyperthermia
Malignant hyperthermia is a genetic condition that causes a person to have a
severe reaction to certain medications and drugs.
The symptoms include a rapid or irregular heartbeat, high body temperature, and
severe muscle spasms. People with this condition require immediate medical
attention.
When to see a doctor
Anyone with a body temperature of 103ºF (39.4ºC) or higher should immediately
see their doctor.
Caregivers should take children under 3 months of age to the doctor if they
have a rectal temperature of 100.4ºF (38ºC) or higher.
In children older than 3 months, a temperature of 102.2ºF (39ºC)Trusted Source
or a fever that lasts longer than 24 hours requires medical attention.
People should visit a doctor if their body heat is higher than usual and they
also have any of the following Trusted Sourcesymptoms:
- difficulty breathing
- irritability, drowsiness, or weakness
- a stiff neck
- light sensitivity
- vomiting
- refusing to drink or becoming dehydrated
- signs of rash or infection
Frequently asked questions
The following are answers to additional questions about high body temperature.
Who is at risk of overheating?
Certain groups are more at risk of dying as a result of excessive outdoor heat.
This includes older adults over 65, children, and people with heart or lung
problems. People from historically marginalized groups who may have less access
to means of cooling down are also more at risk, in particular non-Hispanic
Black people.
How to reduce heat immediately?
This depends on the cause of the high temperature. A person can control a viral
fever with medications such as ibuprofen (Advil). Other health-related causes
may require other treatments. A person should see a doctor to find the
underlying cause and get the best treatment. If the cause is excessive outdoor
heat, a person should drink water, move to a shaded area, and avoid physical
activity.
Which food reduces body heat?
To help a person stay cool in hot weather, a person should eat fresh fruit and
vegetables. Watermelons, cucumbers, and oranges are good choices as they
contain a lot of water and can help a person stay hydrated. In addition, eating
cool dairy products such as yogurt can help reduce body heat. {MEDICAL NEWS

Commandments /Precautions to be observed*Heat wave danger* *Get ready for
the next heat wave* between 40 and 45 °C. Always drink room temperature water
slowly. Avoid drinking cold or ice water!
At present, India, Sri Lanka and other countries are experiencing a "Heat
Wave."
*These are the do's and don'ts:*
1. *Doctors advise not to drink water that is too cold when the temperature
reaches 40°C as our small blood vessels may burst.*
According to reports, a friend of a doctor came home on a hot day - he was
sweating profusely, trying to cool down - and he immediately washed his feet in
cold water... Suddenly, he collapsed and was taken to the hospital.
2. When the outdoor temperature reaches 38°C, when one gets back home, don't
drink cold water, but drink warm water s.l.o.w.l..y. Do not wash the hands or
feet immediately if they are exposed to the hot sun. Wait at least half an
hour before washing or showering.
3. Someone wanted to escape the heat and immediately took a shower. After
showering, the man was taken to the hospital with a stiff jaw and suffered a
stroke.
*KINDLY NOTE :* During the hotter months or if one is very tired, avoid
drinking water that is too cold right away, as it can cause the veins or blood
vessels to narrow, which can lead to a stroke.------RegardsV.SridharanTrichy
