Body temperature is a vital sign that offers a glimpse into the functioning of our internal systems. A normal body temperature typically hovers around 98.6 degrees Fahrenheit (37 degrees Celsius), but recent research has highlighted a downward trend in average body temperature over several decades. In a study, the average temperature of 96 adults over two weeks ranged from 95.4F (35.2C) to 99.3F (37.4C). This variation emphasizes the importance of knowing your normal body temperature range.

Older adults are particularly at risk for hypothermia, where the body’s internal temperature falls too low. Hypothermia can be induced even by prolonged exposure to mild cold, according to Dr. Salamon. It’s crucial to recognize signs that your body isn’t handling the cold well, such as stiffness in the neck and other discomforts.

There are several conditions that could lead to a suddenly or persistently low body temperature, including hypothyroidism, diabetes, liver or kidney failure, infection, endocrine dysfunction, or the side effects of certain medications. Excessive alcohol or drug use can also lower body temperature.

Feeling cold all the time can be attributed to several factors. Low body weight, which means less fat and muscle to insulate and generate heat, significant weight loss, or always being thin could make you more susceptible to feeling cold. Skipping meals can also contribute to a feeling of coldness, as food intake can help maintain body warmth.

During the transition to menopause, known as perimenopause, women may experience a range of symptoms, including sensitivity to cold due to hormonal shifts.

The health risks of extreme temperatures are significant. Dehydration from water and salt loss, especially when sweating, can prevent the body from cooling down effectively. Hypothermia is a serious condition that occurs when the body’s core temperature drops, even by a degree or two, due to cold exposure.
