Sleep is an essential component of good health. It provides the body with the opportunity to rest, repair and rejuvenate. Adequate sleep is known to boost memory, improve mood, reduce inflammation and support immune function.
However, there is a growing body of evidence linking poor sleep to high blood pressure. In this article, we explore the relationship between sleep and high blood pressure, and how you can maintain healthy blood pressure through good sleep hygiene.
What is blood pressure?
Blood pressure is the force that blood exerts on the walls of your blood vessels as it circulates through your body. It is measured in millimeters of mercury (mmHg) and registered as two numbers.
The first number (systolic pressure) measures the pressure in your arteries when your heart beats, while the second number (diastolic pressure) measures the pressure in your arteries when your heart is at rest between beats. Normal blood pressure is considered to be around 120/80 mmHg. However, blood pressure can increase due to a variety of factors, including poor diet, stress, and lack of exercise.
What causes high blood pressure?
High blood pressure, also known as hypertension, is a common condition that affects millions of people worldwide.
It is commonly referred to as a “silent killer” because it often has no symptoms until it causes severe damage to your organs, such as your heart, kidneys, and brain. Chronic high blood pressure can lead to serious and life-threatening conditions such as heart disease, stroke, and kidney failure. Factors that can contribute to high blood pressure include:.
- Poor diet
- Lack of exercise
- Stress
- Smoking
- Alcohol consumption
- Obesity
- Family history of hypertension
How does sleep affect blood pressure?
Studies have shown that people who do not get enough quality sleep are more likely to develop high blood pressure than those who get adequate sleep. Poor sleep can cause a state of chronic stress, raising your heart rate and blood pressure.
When you sleep, your blood pressure falls, allowing your heart to rest and your blood vessels to repair and regenerate. However, if you suffer from sleep disturbances such as sleep apnea or insomnia, your blood pressure may remain elevated even during sleep.
Sleep apnea is a common condition that causes breathing to stop and start during sleep, leading to disruptions in oxygen supply and repeated arousals from sleep.
This can cause elevated blood pressure and increase the risk of heart disease, stroke, and other health problems. Insomnia, on the other hand, is a condition that makes it difficult to fall asleep or stay asleep. Chronic insomnia can cause chronic stress and raise your blood pressure, as well as lead to mood and memory problems.
How can you maintain healthy blood pressure through good sleep hygiene?
Good sleep hygiene is the practice of developing healthy sleep habits to promote quality sleep. It can help you have better sleep quality and duration, which can, in turn, lower your risk of high blood pressure and other health problems.
Here are some tips to promote good sleep health:.
- Stick to a regular sleep schedule, even on weekends and holidays
- Create a relaxing sleep environment that is dark, cool, and quiet
- Avoid caffeine, alcohol, and nicotine before bed
- Avoid large meals and excessive fluids before bedtime
- Unwind before bed by reading, listening to music, or taking a warm bath
- Avoid electronics before bedtime and keep your bedroom free of screens
- Invest in a comfortable mattress and pillows
- Exercise regularly but avoid exercising within 3-4 hours of bedtime
By practising good sleep hygiene and making sleep a priority, you can help regulate your blood pressure and promote overall health and wellbeing.
Conclusion
Sleep and blood pressure are closely connected, with poor sleep quality being linked to an increased risk of hypertension.
The good news is that by making a few lifestyle changes and developing good sleep hygiene habits, you can help protect your health and lower your risk of high blood pressure. Remember to make adequate sleep a priority and seek help if you suffer from sleep disturbances such as sleep apnea or insomnia.
