Low blood pressure, also known as hypotension, can cause a range of unpleasant symptoms, including dizziness, fainting, fatigue, and a need for more sleep. While a decrease in blood pressure is usually not dangerous, it can be concerning for some people, especially if it occurs while they are sleeping. Supine hypotension, for example, refers to low blood pressure that occurs when lying down. In this article, we will explore the effects of low blood pressure during sleep and discuss whether it can wake you up. We will also provide tips and recommendations for managing low blood pressure and improving sleep quality.
| Characteristics | Values |
|---|---|
| Is low blood pressure dangerous? | No, it's usually not dangerous. In fact, people with low blood pressure tend to live longer as their blood vessels are under less stress. |
| What are the symptoms of low blood pressure? | Low endurance, dizziness, fainting, fatigue, a need for more sleep, sweating during exercise, cold extremities, increased sensitivity to temperature changes, episodes of vision loss, pronounced dizziness and palpitations. |
| What is the normal blood pressure reading? | Systolic pressure below 105 for men and 100 for women. |
| What is the normal blood pressure pattern during sleep? | Blood pressure normally decreases during sleep and rises after waking. |
| Who are 'reverse dippers'? | Elderly people, sometimes with diabetes or kidney disease, whose blood pressure increases at night and decreases after waking. |
| Can a lack of sleep affect blood pressure? | Yes, many studies have shown that people who have trouble sleeping are more likely to have high blood pressure. |

What You'll Learn
Low blood pressure can be caused by a lack of sleep
It is unlikely that low blood pressure can wake you up while sleeping. In fact, low blood pressure is usually not dangerous, and those with low blood pressure tend to live longer. However, a drop in blood pressure can cause unpleasant symptoms such as dizziness, fainting, fatigue, and a need for more sleep.
Additionally, there are other factors that can contribute to low blood pressure. For example, supine hypotension refers to low blood pressure that occurs when lying down. This can be managed by keeping your temperature moderate, staying hydrated, and elevating your head while sleeping.
Overall, while it is unlikely that low blood pressure will wake you up while sleeping, a lack of sleep can contribute to high blood pressure over time.

Low blood pressure can be caused by diabetes
Low blood pressure is usually not dangerous, and people with low blood pressure tend to live longer. However, it can cause symptoms such as low endurance, dizziness, fainting, fatigue, a need for more sleep, sweating during exercise, cold extremities, and increased sensitivity to temperature changes. It can also cause episodes of vision loss, pronounced dizziness and palpitations.
Low blood pressure is often associated with high blood pressure, but it can also be caused by diabetes. People with longstanding diabetes can develop damage to the nerves from chronically high blood sugar levels, which can result in autonomic neuropathy, a condition that can cause episodes of low blood pressure. Low blood pressure can also be caused by dehydration, medication side effects, and kidney disease.
Diabetes can cause low blood pressure due to dehydration, autonomic neuropathy, and medication side effects. Autonomic neuropathy is a condition where damaged nerves don't appropriately transmit signals to blood vessels to constrict to maintain blood pressure levels. This can lead to abrupt drops in blood pressure, particularly when standing. Some medications used to treat diabetes can have low blood pressure as a side effect.
People with diabetes are more likely to have high blood pressure, but it can also cause low blood pressure. This is because when blood sugar is very high, as occurs in untreated diabetes, it causes sugar to leak into the urine. This can lead to diabetic nephropathy, which can cause high blood pressure.
If you are experiencing frequent episodes of dizziness and vision changes that are linked to low blood pressure, talk to your healthcare provider about steps you can take to minimize your symptoms and keep your blood pressure at a normal level.

Low blood pressure can be caused by kidney disease
Low blood pressure is not usually dangerous and those with low blood pressure tend to live longer. However, it can cause unpleasant symptoms such as low endurance, dizziness, fainting, fatigue, a need for more sleep, sweating during exercise, cold extremities, and increased sensitivity to temperature changes.
Normally, blood pressure goes down at night during sleep and then rises after waking. For 'reverse dippers' (mostly elderly people, sometimes with diabetes or kidney disease), the pattern is reversed: the blood pressure goes up at night, and then decreases after waking. This means that 'reverse dippers' have their lowest blood pressure during the day.
Low blood pressure is related to poor clinical outcomes in patients with chronic kidney disease (CKD). Lower blood pressure is associated with higher mortality in patients with moderate to severe CKD. However, blood pressure may play a surrogate rather than a causative role in this association.
It is not clear whether low blood pressure can wake you up while sleeping. However, if you are experiencing low blood pressure while lying down, it is recommended that you elevate your head at night by using more pillows or tilting your mattress.

Low blood pressure can be caused by lying down
While low blood pressure is typically not dangerous, it can be unpleasant and impact an individual's quality of life. Those with low blood pressure tend to live longer as their blood vessels are under less stress. However, it is important to note that a regular lack of sleep can contribute to the development of high blood pressure over time.
To manage supine hypotension, it is recommended to keep a moderate temperature, stay hydrated, and avoid sleeping flat. Elevating the head at night by using extra pillows or tilting the mattress can help. Additionally, it is advised to prepare before standing by allowing more time to move from a sitting or lying position to a standing one. Having something sturdy nearby to hold onto when standing up can also aid in preventing dizziness or fainting spells.
Furthermore, certain lifestyle factors can influence blood pressure. Limiting alcohol consumption, avoiding heavy, high-carbohydrate meals, and incorporating isometric exercises, such as squeezing a soft rubber ball or clenching and unclenching hands, can help raise blood pressure.

Low blood pressure can be caused by a lack of hydration
It is important to note that blood pressure normally decreases during sleep and rises after waking. However, for 'reverse dippers', this pattern is reversed, with blood pressure increasing at night and decreasing after waking. While a decrease in blood pressure is usually not dangerous, it can still cause unpleasant symptoms.
To prevent low blood pressure caused by dehydration, it is important to stay adequately hydrated by drinking plenty of water and limiting alcohol consumption. Additionally, it is recommended to elevate your head while sleeping and to give yourself more time to move into a standing position after sitting or lying down.

Frequently asked questions
A decrease in blood pressure is usually not dangerous and those suffering from low blood pressure have a tendency to live longer since their blood vessels are under less stress than those with high blood pressure. However, a drop in pressure can cause symptoms such as dizziness, fainting, fatigue, a need for more sleep, sweating during exercise, cold extremities, and increased sensitivity to temperature changes.
Low blood pressure can cause low endurance, dizziness, fainting, fatigue, a need for more sleep, sweating during exercise, cold extremities, and increased sensitivity to temperature changes. In more severe cases, there can also be episodes of vision loss, pronounced dizziness and palpitations.
To manage low blood pressure, it is recommended to keep your temperature moderate, stay hydrated, elevate your head at night, prepare before standing, and move your muscles.
