Getting enough sleep at the right times can help in improving quality of life and protect mental and physical health. This study proposes a portable sleep monitoring device to determine the relationship between the ambient temperature and quality of sleep. Body condition parameter such as heart rate, body temperature and body movement was used to determine quality of sleep. All readings will be log into database so that users can review back and hence analyze quality of sleep. The functionality of the overall system is designed for a better experience with a very minimal intervention to the user. The simple test on the body condition (body temperature and heart rate) while asleep with several different ambient temperatures are varied and the result shows that someone has a better sleep for the temperature range of 23 to 28 degree Celsius. This can prove by lower body temperature and lower heart rate.

Six adult white-tailed deer (Odocoileus virginianus borealis) were exposed to 165 periods of 12 consecutive hours of controlled constant ambient temperature in an indirect respiration calorimeter. Temperatures among periods varied from 38 to 0 (summer) or to −20C (fall, winter, spring). Traits measured were energy expenditure (metabolic rate), proportion of time spent standing, heart rate, and body temperature, the latter two using telemetry. The deer used body posture extensively as a means of maintaining body energy equilibrium. Energy expenditure was increased at low ambient temperature to combat cold and to maintain relatively constant body temperature. Changes in heart rate paralleled changes in energy expenditure. In a limited number of comparisons, slight wind chill was combatted through behavioral means with no effect on energy expenditure. The reaction of deer to varying ambient temperatures was not the same in all seasons of the year.

Reduction in metabolic rate and body temperature is a common strategy for small endotherms to save energy. The daily reduction in metabolic rate and heterothermy, or torpor, is particularly pronounced in regions with a large variation in daily ambient temperature. This applies most strongly in temperate bat species (order Chiroptera), but it is less clear how tropical bats save energy if ambient temperatures remain high. However, many subtropical and tropical species use some daily heterothermy on cool days. We recorded the heart rate and the body temperature of free-ranging Pallas' mastiff bats ( Molossus molossus ) in Gamboa, Panamá, and showed that these individuals have low field metabolic rates across a wide range of body temperatures that conform to high ambient temperature. Importantly, low metabolic rates in controlled respirometry trials were best predicted by heart rate, and not body temperature . Molossus molossus enter torpor-like states characterized by low metabolic rate and heart rates at body temperatures of 32°C, and thermoconform across a range of temperatures. Flexible metabolic strategies may be far more common in tropical endotherms than currently known.

Sleep is a form of rest and getting enough sleep at the right times with suitable surrounding conditions is very important to maintain good health throughout life. The study aims to develop the end-user prototyping for a sleep monitoring system that measures the room ambient and body condition by using a wireless device utilizing Bluetooth Low Energy (BLE) embedded system. For the user interface, the Window application is used to display the collected data from separate ambient parameters and body condition embedded systems using Bluno Uno and Bluno Nano respectively. This sleep monitoring system also equipt with a video and audio based recording from the web camera and microphone of the built-in PC based unit. Capturing data from body monitoring and ambient monitoring separate units are then transferred to the Window based application by using the BLE connection and lastly, the captured data are log into the MySQL database with the date and time stamp. The ambient condition system captured the room temperature and humidity, light intensity and rate of CO2 concentration. The body condition system, it is measuring body temperature, heart rate and body movement. Based on the device testing on sleep monitoring, each of the parameters measured is optimized to choose the best possible occurrence of ambience setting selection for optimal sleep quality.

Characteristics of cold acclimation in the golden hamster, Mesocricetus auratus, were 1) higher metabolic rate at -30 C, 2) less shivering when related to ambient temperature or oxygen consumption, and 3) higher differences in body temperature between cardiac area and thoracic subcutaneous tissues at all ambient temperatures tested, indicating changes in tissue insulation. Cold-acclimated hamsters also showed a rise in temperature of the cardiac area when ambient temperature was below 15 C. Changes in heat distribution in cold-acclimated hamsters suggest higher blood flow and heat production in the thoracic part of the body in the cold. The thermal conductance through the thoracic and lumbar muscle areas, however, did not change notably with lowering ambient temperature. Marked differences in thermoregulatory response to cold after cold acclimation were found between two species, the golden hamster and the thirteen-lined ground squirrel, showing greater ability to regulate body temperature in the cold in hamsters. hibernator; oxygen consumption— heat production; body temperature — heat conductance; muscular activity — shivering; thermoregulation Submitted on July 6, 1964

A cozy room should adjust its environment based on the condition of its occupants since it will indirectly affect the moods and body conditions of people inside. This study aims to develop a system for monitoring the human body condition using paired sensors on the Arduino Lilypad. The system will send the sensors data to the Raspberry Pi3 via Bluetooth to automatically control the electronic device inside the room based on the occupant body condition. The developed system will automatically turn on or turn off the electronic device when the body temperature or the heart rate is higher than the specified threshold value. Keywords: Lilypad, Raspberry, body sensor

The Right

The peripheral end of the right vagus was stimulated in acutely vagotomized rats under anaesthesia at different body temperatures. A fairly abrupt increase in the R–R time on the electrocardiogram was observed when a critical stimulation frequency was reached. At a body temperature of 35 °C. the critical frequency is 10 per second or more. On lowering of the body temperature to 28 °C. the critical frequency is greatly reduced so that considerable slowing may be elicited at frequencies as low as one to five per second. Possible theoretical models to account for the critical frequency and its variation with temperature are considered. The temperature effect is too great to be accounted for either on the basis of the increased number of impulses which reach the heart per cardiac cycle, or the reduced rate of cholinesterase activity. The theory most consistent with the results is that each vagal impulse liberates or inactivates a substance, the concentration of which varies directly with heart rate. The interimpulse interval at the critical frequency would then represent the regeneration time of this substance. The temperature coefficient of the regeneration process appears to be about 3.3 per 10 °C.

Behavioural Responses

We have studied the physiological and behavioural responses in small rodents to ambient alterations. For this purpose, voles and mice were exposed to relatively low (12°C) and high (35°C) ambient temperatures, and heart rate (HR), locomotor activity (LA) and body temperature (BT) were recorded using telemetry system. The control HR (at 24°C) of voles was lower than that of mice. The 'heat exposure' decreased HR to 85.0±3.3% in voles, and to 78.0±3.2% in mice compared with the mean HR of the same time in the control day. The 'cold exposure' increased the HR to 131.9±8.8% in voles, and 119±10.9% in mice. The decreasing rate of HR in heat exposure was smaller in voles than mice, and in cold exposure the increased rate was larger in voles than mice. Cold exposure decreased BT in both species; 96.1±0.5% in voles and 93.7±1.0% in mice. The LA was not changed significantly by heat exposure in either species, but was partially increased by cold exposure. These results demonstrate that telemetry was helpful for qualitative and quantitative behavioural studies in small rodents, and confirmed that the physiological and behavioural responses to ambient temperature changes differed between these animals.

Body Weights

Goldthioglucose-obese mice cannot adjust their food intake to meet the increased energy requirements due to cold. At all ambient temperatures above 15°C the spontaneous running activity of these animals is less than that observed for nonobese controls. Activity of obese mice is maximal at 19°C and minimal at 15°C or lower. Body weights decrease during exposure to cold. In contrast to that of obese mice, running activity of nonobese controls is maximal at an ambient temperature of 25°C but nearly ceases at 15°C or lower. The food intake of these animals increases in the cold and remains elevated even at temperatures at which activity decreases. The body weight of nonobese controls is either maintained constant or increases during exposure to cold air.

AbstractEndometriosis is a common condition that affects reproductive-aged women and is characterized by the presence of endo-metrial tissue outside the uterine cavity with nodules and lesions. The study aimed to analyze lifestyles of women affected by endometriosis in relation with their symptoms. In this observational study, 735 Italian women have been interviewed online through a questionnaire structured in two parts. The first part was mainly anamnestic, focused on gathering information about the age, the stage of disease, comorbidities, involved organs, symptomatology, chirurgical treatment, induced menopause. The second part focused on the individual characteristics and lifestyle of the patients such as the body mass index, physical activity, quality of sleep, and the diet. The results showed how a healthy diet and a regular physical activity reduce drastically the symptoms of the patients.
