Night sweats, also known as hot flashes or vasomotor symptoms (VMS), are sudden episodes of sweating that occur while you are asleep. These episodes can last anywhere from one to 10 minutes and are often accompanied by feelings of flushness, upper body and facial sweating, and subsequent chills as the hot flash subsides. Heart palpitations may also occur during these episodes.
Night sweats are common during the menopause transition, affecting up to 74 percent of perimenopausal women. The duration and frequency of these episodes can vary, with some women experiencing them infrequently while others may have them multiple times a day. These symptoms are associated with hormonal changes, particularly decreases in estrogen levels, that disrupt the body’s temperature regulation system.
In addition to hormonal changes, there are several other factors that can contribute to night sweats. These include room temperature, heavy bedding or sleepwear, alcohol consumption, certain medications, infections, hyperhidrosis (excessive sweating), stress and anxiety, sleep apnea, and thyroid problems.
If you are experiencing frequent night sweats, it’s important to speak with your doctor to determine the underlying cause and receive appropriate treatment. Night sweats should not be ignored, as they can significantly impact the quality of your sleep and overall well-being. Experts recommend seeking help if you are experiencing persistent or severe night sweats, as there are effective interventions available to help manage this symptom.
