Feeling cold and hot at different times of day
Overview
Feeling cold and hot at different times of day is a symptom characterized by fluctuating body temperature sensations where a person experiences chills or coldness alternating with periods of feeling overheated or feverish. This temperature dysregulation can occur throughout the day without a consistent pattern and may indicate underlying health conditions affecting the body's thermostat.
Common Causes
Your body's internal temperature naturally fluctuates throughout the day due to your circadian rhythm, with temperatures typically being lowest in the early morning and highest in late afternoon. Hormonal changes, particularly in women during menstruation, pregnancy, or menopause, can cause sudden temperature shifts. Stress, anxiety, and changes in blood sugar levels from irregular eating patterns can also trigger these hot and cold sensations. Poor circulation, dehydration, or wearing inappropriate clothing for the temperature can make you more sensitive to environmental changes throughout the day.
Severity Levels
Mild: You notice occasional temperature fluctuations but can manage daily activities with simple adjustments like adding or removing layers of clothing. The sensations are brief and don't significantly impact your routine.
Moderate: Temperature swings occur more frequently and are noticeable enough to affect your comfort and concentration throughout the day. You may need to regularly adjust your environment or clothing, and the fluctuations might interfere with sleep or work productivity.
Severe: Extreme and frequent temperature changes that significantly disrupt your daily life, sleep, and ability to function normally. The sensations may be accompanied by sweating, shivering, or other concerning symptoms that require immediate medical attention.
Medical Attention
Seek medical attention if these temperature fluctuations persist for more than a few days or are accompanied by fever, severe fatigue, unexplained weight loss, or night sweats. Contact your doctor immediately if you experience chest pain, difficulty breathing, or signs of infection along with the temperature changes. If the symptoms interfere with your daily activities or sleep, schedule an appointment with your healthcare provider to determine the underlying cause.
