Blodtrycksjupet

Blodtrycksjupet is a Swedish term that translates to "blood pressure dip" or "low blood pressure phase." It refers to a natural physiological phenomenon where blood pressure experiences a significant drop during certain periods, most notably during sleep. This dip is a normal and healthy part of the circadian rhythm, the body's internal biological clock that regulates sleep-wake cycles and other physiological processes over a 24-hour period.

The most prominent blood pressure dip occurs during the night, typically starting a few hours after falling asleep and continuing until a few hours before waking. During this time, blood pressure can decrease by 10-20% compared to daytime levels. This nocturnal dipping is believed to be crucial for cardiovascular health, allowing the heart and blood vessels to rest and recover from the demands of the day. It is also thought to play a role in fluid balance and kidney function.

The absence of this normal blood pressure dip, known as a non-dipping pattern, has been associated with an increased risk of cardiovascular diseases, including hypertension, stroke, and heart attack. Factors such as age, certain medical conditions, and lifestyle choices can influence whether an individual experiences a normal dip or a non-dipping pattern. Medical professionals may monitor blood pressure patterns, including the nocturnal dip, as part of a comprehensive assessment of cardiovascular health.
