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 <https://www.ncbi.nlm.nih.gov/books/NBK507838/> (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 <https://www.cdc.gov/quarantine/air/reporting-deaths-illness/definitions-symptoms-reportable-illnesses.html> (38ºC) usually indicates fever <https://www.medicalnewstoday.com/articles/168266.php>. Simply being outdoors on an extremely hot day can be enough to cause heat exhaustion or heat stroke. <https://www.medicalnewstoday.com/articles/321972> 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) <https://www.ncei.noaa.gov/access/monitoring/monthly-report/global/202113> per decade for nearly 150 years. At the same time, a 2021 study estimates that 37%Trusted Source <https://www.nature.com/articles/s41558-021-01058-x> 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 <https://www.ncbi.nlm.nih.gov/books/NBK507838/>: - 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 <https://www.medicalnewstoday.com/articles/312628> 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 <https://www.medicalnewstoday.com/articles/312628> 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 <https://www.medicalnewstoday.com/articles/153363.php>, which can increase <https://www.researchgate.net/publication/274063254_What_effect_does_hydration_have_on_body_temperature> body heat. 2. Go somewhere with cooler air People can reduce their body temperature by movingTrusted Source <https://www.cdc.gov/niosh/topics/heatstress/recommendations.html> 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 <https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5777660/> 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 <https://www.ncbi.nlm.nih.gov/books/NBK459311/> 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 <https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5868221/> 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 <https://www.medicalnewstoday.com/articles/155651.php>. 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 <https://www.medicalnewstoday.com/articles/9153.php>. When this is the case, a person might alsoTrusted Source <https://www.ncbi.nlm.nih.gov/books/NBK278927/> notice other symptoms, such as a rapid heart rate, sweating, jaundice <https://www.medicalnewstoday.com/articles/165749.php>, 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 <https://www.cdc.gov/disasters/extremeheat/warning.html>: 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 <https://www.medicalnewstoday.com/articles/73936.php> - 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 <https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5198803/> 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 <https://www.medicalnewstoday.com/articles/155651>, people often experience hot flashes <https://www.medicalnewstoday.com/articles/hot-flash-causes> and night sweats, which temporarily elevateTrusted Source <https://www.ncbi.nlm.nih.gov/books/NBK507826/> 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 <https://www.medicalnewstoday.com/articles/173068.php> - neuroleptic drugs - inhaled anesthetics - succinylcholine These medications either impairTrusted Source <https://onlinelibrary.wiley.com/doi/10.1111/jcpt.12294> 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 <https://journals.lww.com/nursing/Fulltext/2008/06000/FEVER_AND_HYPERTHERMIA__LEARN_TO_BEAT_THE_HEAT.28.aspx> because they increase the metabolic rate. These includeTrusted Source <https://accp1.onlinelibrary.wiley.com/doi/pdf/10.1002/jcph.1918> 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 <https://www.medicalnewstoday.com/articles/312442.php> 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 <https://www.ncbi.nlm.nih.gov/books/NBK278927/>: - rapid heartbeat - sweating - nausea or vomiting - agitation - jaundice - abdominal pain Malignant hyperthermia Malignant hyperthermia is a genetic condition that causes <https://www.health.harvard.edu/a_to_z/malignant-hyperthermia-a-to-z> 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 <https://familydoctor.org/condition/fever-in-infants-and-children/> (38ºC) or higher. In children older than 3 months, a temperature of 102.2ºF (39ºC)Trusted Source <https://www.ncbi.nlm.nih.gov/books/NBK279455/> 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 Source <https://www.cdc.gov/quarantine/air/reporting-deaths-illness/definitions-symptoms-reportable-illnesses.html#:~:text=CDC%20considers%20a%20person%20to,a%20history%20of%20feeling%20feverish.> symptoms: - 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 <https://www.epa.gov/climate-indicators/climate-change-indicators-heat-related-deaths>, 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 <https://www.fema.gov/blog/6-ways-stay-cool-extreme-heat> 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 <https://cops.usdoj.gov/html/dispatch/07-2019/keeping_cool.html> 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 TODAY} KR IRS 17 5 23 On Tue, 16 May 2023 at 12:03, 'venkat giri' via iyer123 < [email protected]> wrote: > *Respected Sir/s,* > * Weather forecast indicates very HOT & DRY weather* > > > > > > > > > > > > > > > > *2 Week Extended Forecast in Chennai, Tamil Nadu, > India ConditionsComfortPrecipitationSunDay TemperatureWeatherFeels > LikeWind HumidityChanceAmountUVSunriseSunsetWed17 May35 / 30 °CMorning > clouds.50 °C30 km/h↑73%20%0.1 mm10 (Very high)05:4318:27Thu18 May35 / > 30 °CSunny.49 °C33 km/h↑73%0%-10 (Very high)05:4218:27Fri19 May35 / > 29 °CSunny.50 °C33 km/h↑73%0%-10 (Very high)05:4218:28Sat20 May35 / > 30 °CSunny.50 °C32 km/h↑72%3%-10 (Very high)05:4218:28Sun21 May35 / > 30 °CMostly sunny.50 °C32 km/h↑70%0%-10 (Very high)05:4218:28Mon22 May35 / > 29 °CSunny.49 °C33 km/h↑70%0%-10 (Very high)05:4218:29Tue23 May36 / > 29 °CSunny.47 °C31 km/h↑65%0%-10 (Very high)05:4218:29Wed24 May36 / > 29 °CSunny.41 °C24 km/h↑50%5%-10 (Very high)05:4118:29Thu25 May37 / > 29 °CScattered clouds.44 °C23 km/h↑53%5%-10 (Very high)05:4118:29Fri26 > May37 / 30 °CAfternoon clouds.44 °C24 km/h↑54%6%-7 (High)05:4118:30Sat27 > May37 / 30 °CPartly cloudy.39 °C10 km/h↑42%6%-7 (High)05:4118:30Sun28 May37 > / 30 °CScattered clouds.41 °C18 km/h↑47%6%-10 (Very high)05:4118:30Mon29 > May37 / 30 °CMostly cloudy.40 °C16 km/h↑43%6%-3 (Moderate)05:4118:31Tue30 > May37 / 30 °CScattered clouds.42 °C20 km/h↑48%6%-10 (Very > high)05:4118:31Wed31 May37 / 30 °CScattered clouds.41 °C19 > km/h↑46%6%-7 (High)05:4118:31* Updated Tuesday, 16 May 2023 20:52:40 > Chennai time - Weather by CustomWeather, © 2023Commandments /Precautions to > be observed* > > > > > > > > > > **Heat wave danger* *Get ready for the next heat wave* between 40 and > 45 °C.
