Dangerous Temperatures for the Elderly. The elderly are at higher risk than the general population for temperature- related health issues. The body's reduced ability to regulate temperature, medical problems, medications and the environment are all factors affecting the ability of elderly individuals to maintain a healthy body temperature. Dangerous body temperatures are below 9. Fahrenheit or above 1. Fahrenheit for the general population.

Elderly individuals have a narrower range of safe temperatures, varying by approximately 2 degrees on either end of the scale. Healthy young adults adapt to temperature changes through various processes aimed at core body temperature maintenance. Sweating cools the body and shivering warms the body. Although there is variation among individuals, the elderly lose these thermoregulation functions, with reduced ability to sweat and shiver.

Blood circulation problems increases thermodysregulation responses. Decreased thirst awareness affects body temperature in the elderly, as dehydration further reduces the body's ability to maintain a steady temperature. Hypothermia results when an individual's core body temperature drops below 9. Fahrenheit. While vasoconstriction and shivering in healthy young adults act to increase the body temperature and prevent damage, the elderly do not respond with these autonomic reactions until their temperature is significantly lower. Furthermore, the geriatric population has a prolonged reaction to hypothermia, taking longer to respond to interventions to help them warm up and return to a healthy temperature. Hyperthermia is the result of the body overheating.

The elderly are at higher risk for hyperthermia because of the normal aging process of decreased autonomic responses for cooling, chronic medical conditions and certain medications. Symptoms of hyperthermia range from uncomfortable to life- threatening. Cramps caused by excessive heat are accompanied by moist, cool skin. Swelling of the ankles and feet, edema or sudden dizziness known as heat syncope can result from overheating. Heat exhaustion causes dizziness, thirst, sweating and nausea, but the body temperature remains normal. Heat stroke results when the body temperature exceeds 1.

Fahrenheit. Confusion and fainting are signs of this medical emergency. Measures to prevent dangerous body temperatures when the weather is hot include drinking water, avoiding alcohol and caffeine, taking cool baths or showers, staying indoors during the heat of the day, using cooling fans or air conditioners and avoiding excessive exercise. Special care should be taken to keep the elderly warm in cold environments, including operating rooms. Annual General Meeting there. The slower temperature regulation reaction times and the prolonged recovery times from hypothermia make it necessary to take measures to reduce heat loss in the elderly by using warm blankets, warm baths or other means of conserving heat.

Human Body Temperature: Fever - Normal - Low Readings. Published: 2. 01. Revised/Updated 2. Disabled World (Disabled World).

Synopsis: Information and conversion charts of human body temperatures including normal, high and low readings. Main Document. Did you know normal human body temperature is also known as normothermia or euthermia? And your body temperature can be measured in many locations including, mouth, ear, armpit, forehead, and rectum? However, your body temperature reading will vary depending on where the measurement is taken - eg. C lower than the body's core temperature (the temperature of the internal organs) - the time of day, your age, and activity level, and, in women, the stage of menstrual cycle can affect your temperature reading. Quick Facts: Body temperature can change throughout the day.

Body temperature may be abnormal due to fever (high temperature) or hypothermia (low temperature). A temperature over 3. C (1. 00. 4°F) most often means you have a fever caused by infection or illness. It is generally medically accepted that normal body temperature ranges between 3. C (9. 7. 7°F) to 3. C (9. 9. 5°F). Body Temperature Can be Taken Either: Orally - By mouth - glass thermometer, or a digital thermometer. Rectally - Temperatures taken rectally tend to be 0.

F HIGHER than when taken by mouth. Forehead (Skin) - A special thermometer can quickly measure the temperature of the skin on the forehead.

Ear - A special thermometer can quickly measure the temperature of the ear drum, which reflects the body's core temperature. Axillary - Temperature taken under the arm (armpit) tend to be 0. F LOWER than those temperatures taken by mouth. What is the Normal Body Temperature for a Baby? The American Academy of Pediatrics (AAP) states a normal body temperature for a healthy baby is between 9. Fahrenheit. If the rectal temperature is 1. What is the Normal Body Temperature for Children?

The average normal body temperature for children is about 3. C (9. 8. 6°F). A child's temperature usually averages from around 3.

C (9. 7. 4°F) in the morning to 3. C (9. 9. 6°F) in the afternoon. What is the Normal Body Temperature for Adults? Temperature in the mouth (oral) is about 3.

C (9. 8. 2°F)Temperature under the arm (axillary) is about 3. C (9. 7. 7°F)Temperature in the anus (rectum/rectal), vagina, or in the ear (otic) is about 3. C (9. 9. 5°F)At What Temperature Are You said to Have a Fever? According to the American Academy of Family Physicians, a fever is indicated when body temperature rises about one degree or more over the normal temperature of 3. Celsius (9. 8. 6 degrees Fahrenheit). About This Image: Body temperature thermometer. Adults: A fever is generally agreed to be present if: Temperature in the mouth (oral) is at or over 3.

Basal body temperature is generally measured immediately after awakening, although the temperature measured at that time is somewhat higher than true basal body temperature. In women, body temperature will differ at various points in the menstrual cycle, and this temperature change can be used to track ovulation to aid conception or avoid pregnancy. What is Core Body Temperature? Core temperature is the operating temperature of an organism, specifically in deep structures of the body such as the liver, in comparison to temperatures of peripheral tissues. Core temperature is normally maintained within a narrow range so that essential enzymatic reactions can occur.

What is Hyperpyrexia? The word used for a fever with an extreme elevation of body temperature greater than or equal to 4. C (1. 06. 7°F). What is Hyperthermia? A high temperature that is not a fever. Causes include heatstroke, neuroleptic malignant syndrome, idiosyncratic drug reactions, malignant hyperthermia, stimulants like amphetamines or cocaine, and serotonin syndrome.

What Body Temperature Denotes Hypothermia? Hypothermia is defined as a drop in body temperature below 9.

What Is a Normal Heart Rate While Sleeping? Sleep represents an uninterrupted, unconscious resting time for your body and mind. Adults typically require 7 to 9 hours of sleep daily, according to 2.

National Sleep Foundation. During sleep, your heart rate normally slows due to complex regulatory mechanisms. Normal sleeping heart rate depends on multiple factors, including your resting heart rate while awake and the stage of sleep, which varies during the night. Certain medical conditions can also affect your sleeping heart rate. Transitioning from wakefulness to sleep involves complex signaling that affects heart rate, blood pressure and body temperature as well as other body parameters and functions. Average heart rate during sleep decreases by roughly 2. March 2. 00. 9 "New England Journal of Medicine" article.

The decrease begins as you fall asleep and continues, on average, as you pass into deeper stages of sleep. A lower heart rate during sleep occurs primary because nerve signals that your slow heart rate increase during sleep while nerve signals that speed heart rate are suppressed. However, your heart rate varies from one sleep stage to another. Two main types of sleep occur as you slumber. These are known as REM and non- REM sleep.

REM is an acronym for rapid eye movement, which characterizes the type of sleep most closely associated with vivid dreams. Non- REM sleep is further divided into three stages: N1, N2 and N3. N3 is the deepest stage of non- REM sleep. You cycle through N1 to N3 and then progress to REM several times during a normal night of sleep. In general, your heart rate is lower during non- REM sleep than it is when you are in REM sleep or awake.

Non- REM sleep normally accounts for approximately 7. REM sleep accounts for approximately 2. While dreaming occurs in both types of sleep, REM sleep is most closely associated with vivid, story- like dreams that can be recalled upon awakening.

REM sleep represents a distinctly different state compared to non- REM sleep in terms of brain activity and your body's physiologic functions. Your heart rate during REM sleep is typically higher and more variable than in non- REM sleep stages. This may be due to a combination of factors, including increased blood flow and activity in certain areas of the brain, and augmented nerve signals that speed the heart rate. Because sleep is a dynamic process consisting of several multi- stage cycles per night, your heart rate varies significantly as you sleep - - just as it does when you're awake. Additionally, a number of variables can affect your typical sleeping heart rate, including your age, sex, cardiovascular fitness level and medications. Group Activities For Mental Health Adults more. As such, there is no standard "normal" range for heart rate during sleep. If a nighttime heart rate or rhythm abnormality is suspected, a 2.

People with certain medical conditions are prone to heart rate or rhythm abnormalities during sleep. Obstructive sleep apnea (OSA), for example, sometimes causes a significant drop in blood oxygen, leading to heart rate or rhythm abnormalities. The drop in blood oxygen occurs due to periodic pauses in breathing during sleep. Morning headaches, excessive daytime sleepiness and snoring are common symptoms of OSA. Insomnia, frequent nighttime awakenings and other conditions that cause fragmented or disordered sleep can also affect heart rate.

People who have suffered a heart attack may also experience nighttime heart rate or rhythm abnormalities. Those with congestive heart failure are similarly vulnerable to heart rate or rhythm problems. A significant nighttime heart rate or rhythm abnormality typically requires treatment with medication or a pacemaker. Reviewed and revised by: Tina M.
