When you battle with your bedding and pillows to locate the only cool area on the bed, your sleep deprivation can affect your body's capacity to manage your temperature cycle, and your failure to regulate temperature can lead to more sleeplessness in the long run. The best solution for this problem is to find a more comfortable place to sleep - even if it means moving away from home. Your body temperature varies throughout the day in order to keep you healthy. For example, your core body temperature rises when you wake up in the morning because your body needs energy to start the day. This rise is why you feel warm when first waking up. As you continue to wake up and go about your daily activities, your core body temperature will eventually return to its normal level. Your body temperature also varies during sleep. When you are sleeping at room temperature, your brain sends out signals to certain parts of your body to produce more heat to maintain your body temperature at a stable level. For example, when you are asleep at room temperature, your body will release more adrenaline into your blood stream which will cause your heart to beat faster and your muscles to tense up in order to raise your temperature. Once your body temperature reaches 36 degrees Celsius (97.8 degrees Fahrenheit), you will enter into a deep stage of sleep called hypothermia, which is necessary for good health.
