In the short term, dehydration can thin your blood volume and lead to low blood pressure. Less water in your body means less water in your blood, which can cause your blood pressure to spike or fall. When the temperature of your environment increases, your blood pressure naturally decreases, leading to feelings of dizziness and lightheadedness.ĭehydration in itself can also affect your body's ability to regulate your temperature - when dehydrated, you sweat less, making it harder for your body to cool off. If you don't drink enough water, especially when it's hot out, you can easily overheat and get dehydrated.

Until your blood continues to circulate throughout the rest of your body, your blood pressure can fluctuate, causing dizziness. Thanks to gravity, your blood briefly pools in your lower body when you stand up, and it may take your body a few seconds, even a minute, to adjust. When your body gets used to functioning in a certain position, shifting positions can shock your system, so to speak, by momentarily depriving your brain of blood. In fact, your blood pressure naturally changes based on your position in order to maintain homeostasis, a state of balance that allows your body's many systems to function properly.
