Understanding the threshold for hypothermia is crucial for medical and personal health. Recent research confirms that the average body temperature has been decreasing over decades, and now ranges widely. Studies have found that normal temperatures can range from 35.2°C (95.4°F) to 37.4°C (99.3°F), suggesting that personal baselines are more informative than a single standard figure.
Hypothermia is a serious condition that occurs when body temperature drops below 35°C (95°F). It is important to note that normal body temperature is traditionally around 37°C (98.6°F), but modern studies indicate that it may now average lower, around 36.6°C (97.9°F). This shift could be due to various factors, including changes in lifestyle, environment, and physiology.
Factors that may contribute to a lower body temperature include hypothyroidism, diabetes, liver or kidney failure, infections, endocrine dysfunctions, and the side effects of certain medications. Lifestyle factors, such as excessive alcohol or drug use, can also lower body temperature. It is essential to be aware of these conditions and seek medical advice if a low body temperature is persistent.
Elderly adults are particularly at risk for hypothermia, even in mild cold conditions. Awareness of symptoms like stiffness in the neck and understanding that body temperature can vary throughout the day are important in managing health risks associated with low body temperatures.
If you feel cold frequently, it could be due to low body weight, which affects your body’s ability to stay warm. Both muscle and fat play roles in body heat—muscle through heat generation and fat as insulation. Therefore, weight changes can make a person more sensitive to the cold.
