Hot flashes are characterized by a sudden feeling of intense heat that starts around your head and neck and spreads down to your chest, says FamilyHealthGuide.co.uk. Lightheadedness is a feeling of dizziness or faintness, either when sitting or standing, says livingwithanxiety.com. There are three common causes of feeling overheated and lightheaded simultaneously.


Hot flashes are one of the most common symptoms of menopause, with three-quarters of women experiencing them, says FamilyHealthGuide.co.uk. They can start up to two years before menopause begins and may last for several years. The exact reason for hot flashes during menopause is unknown, but they may be due to changes in the part of your brain that controls temperature. Lightheadedness is a lesser known, but nonetheless common, symptom of menopause, says 34 Menopause Symptoms. It is thought to be caused by hormonal changes that can affect your nervous system, leading to bouts of dizziness and/or a feeling of being off balance.


Lightheadedness and sweating are common symptoms of hyperventilation, says the Patient UK website. This condition is characterized by a feeling of being out of breath and rapid breathing, beyond what is necessary to deliver oxygen to your system. If your condition is persistent, you should see a doctor for an accurate diagnosis and treatment plan.


Hot flashes and lightheadedness are common symptoms of anxiety, says livingwithanxiety.com. If you suffer from continual anxiety and its associated symptoms, you should seek medical attention. Anxiety is closely linked with the other two causes discussed in this article, as it is a possible cause of hyperventilation, says Patient UK, and can also make hot flashes and lightheadedness worse during menopause, says the womentowomen website.
