Does lack of sleep or insomnia increase blood pressure?

Yes, lack of sleep or poor quality sleep can increase blood pressure. Studies have shown that individuals who consistently get less than 6 hours of sleep per night are at increased risk of developing high blood pressure. Additionally, poor sleep quality, characterized by frequent waking, snoring, or sleep apnea, has also been associated with higher blood pressure levels.
There are several ways in which lack of sleep can affect blood pressure. One mechanism is through the activation of the sympathetic nervous system, which can cause blood vessels to constrict and increase blood pressure. Lack of sleep can also lead to an increase in the stress hormone cortisol, which can also contribute to higher blood pressure.
Furthermore, chronic sleep deprivation can lead to a state of inflammation in the body, which can also contribute to the development of high blood pressure.
Overall, it is important to prioritize adequate sleep to help maintain healthy blood pressure levels. The American Heart Association recommends that adults aim for 7-9 hours of sleep per night for optimal health. If you are having trouble sleeping, it is important to speak with a healthcare provider to determine the underlying cause and develop a treatment plan.
