How Dangerous Is High Blood Pressure
High blood pressure, also known as hypertension, is classified as Stage One or Stage Two. Stage One hypertension is a reading of 130/80 mm Hg or above, while Stage Two has readings of 140/90 mm Hg or above. Anything exceeding 180/120mm is considered a medical emergency.
If youve been diagnosed with hypertension, or youve just experienced a sudden spike in blood pressure, youre far from alone. In fact, according to the CDC, 45 percent of adults in the United States experience high blood pressure, and only a quarter of those have their blood pressure properly being treated.
But just how dangerous is high blood pressure?
Blood pressure can have a dramatic impact on your health, especially if you have chronic hypertensionbut even sudden spikes in high blood pressure can contribute to the following.
Tips For Getting Enough Sleep Each Night
Practicing sleep hygiene is crucial to receiving an adequate amount of rest on a nightly basis. Key aspects of sleep hygiene include:
Follow a consistent sleep schedule: Go to bed and wake up at the same times, even on the weekends or when you’re on vacation.
Chronic sleep deprivation should be taken seriously. If you aren’t getting enough sleep on a regular basis, consult with your doctor or another credentialed physician about ways to address this issue and improve your sleep allotment.
Take Care Of Your Sleep Apnea If You Suspect You Are Experiencing It
Get your blood pressure levels under control by making sure you rule out a sleep disorder. If youve been experiencing symptoms of sleep apnea, or even if your partner complains about your snoring, its important not to let it go unchecked. Pay Attention to Your Diet
Its not the most fun advice, but just as taking care of your sleep is important for regulating your blood pressure, youll continue to struggle with hypertension if you ignore your diet. Reduce your sodium intakethe American Heart Health Association recommends a maximum limit of 2,300mg per day, but ideally less than 1,500 mg a day. Youll also want to include healthy fats from nuts and seeds, fresh produce, and limit your intake of saturated fat. Trans fats and fried foods should be eliminated as much as possible.

Silent Killer Health Risks
Results indicate that nighttime systolic blood pressure was a significant, independent risk factor for cardiovascular events, said Dr. Kazuomi Kario, the lead author of the study and a professor of cardiovascular medicine at Jichi Medical University in Tochigi, Japan.
The study highlights the importance of including nighttime blood pressure monitoring in patient-management strategies and will hopefully encourage physicians to ensure that antihypertensive therapy is effectively lowering blood pressure throughout the 24-hour dosing period.
For the study, Japanese researchers studied 6,359 people, using wearable monitors to measure both daytime and nighttime blood pressure.
The participants all had at least one cardiovascular risk factor, and most were taking medication to control their blood pressure. However, none had symptomatic cardiovascular disease when the study started.
During 2-year to 7-year follow-ups of the participants, researchers said they found those who had nighttime systolic blood pressure that was 20 millimeters of mercury above their daytime systolic reading were significantly more likely to experience atherosclerotic cardiovascular disease and heart failure.
Overall, study participants experienced a total of 306 cardiovascular events, including 119 strokes, 99 diagnoses of coronary artery disease, and 88 diagnoses of heart failure.
Easy Before Bed Routines For People With Diabetes
Managing diabetes whether you have type 1 or type 2 is a full-time job. Your condition doesnt clock out at 5 p.m. when youre ready to take a break. You have to maintain your blood sugar checks, medication, exercise, and eating habits all day to keep your disease under control.
In fact, you should be mindful of your diabetes all the way until bedtime. Before you set the alarm and settle in under the covers each night, here are a few bedtime to-dos that will help you get more control over your diabetes and sleep more soundly.

How Does Sleep Apnea Cause High Blood Pressure
Each time a person with OSA experiences airway collapse and briefly stops breathing during sleep, their sympathetic nervous system becomes activated and blood pressure rapidly spikes when they resume breathing. Sometimes, this sequence of pausing and resuming breathing can cause a person to wake from sleep. When a person wakes up after an OSA event, activation of the sympathetic nervous system and blood pressure levels escalate to an even greater degree.
Additionally, when sleep is disrupted by OSA symptoms, the body releases sympathetic nervous system hormones called catecholamines into the blood. Catecholamines are stress hormones that are majorly released by the adrenal glands. Examples of catecholamines include dopamine and epinephrine . High levels of catecholamines in the blood cause high blood pressure.
High Blood Sugar: 13 Reasons Your Glucose Levels Are Rising
ItÃ¢s a fact of life that blood sugar fluctuates throughout the day. These ups and downs depend on a handful of factors, like when you wake up, what you eat, the medications you take, and how you manage stress. So, some variation is normal, to the point that you might not even notice it.
Ignoring blood sugar level changes altogether, though, means youÃ¢re ignoring a valuable marker of your health. Especially if you start to have new or unfamiliar symptoms like fatigue, thirst, or brain fog . Learning these symptoms and their causes will give you the tools to better understand your own body, then take the right actions for better long-term metabolic health.

How Much Sleep Does A Person Need
The average adult should receive at least seven hours of sleep for every 24-hour cycle. Sleeping less than seven hours can leave you more vulnerable to different diseases and medical conditions, and also affect your ability to concentrate and increase your risk of errors and accidents. That said, the sufficient amount of sleep for a given individual depends on their age.
Insufficient sleep creates a problem known as sleep debt. Let’s say you are an adult 18 years or older who receives six hours of sleep every night. Just one week of inadequate rest produces seven hours of sleep debt. Napping can provide a quick pick-me-up, but it does not deliver the same restorative functions of nightly sleep. As a result, chronic sleep deprivation can lead to serious health problems down the road.
What Happens To Your Body When You Don’t Sleep
Sleep deprivation often leads to tiredness during the day. You may wake up feeling less refreshed and alert than you might after seven to nine hours of uninterrupted sleep, and this can affect how you perform in different professional and social settings. Other immediate side effects of inadequate sleep include anger and irritability, impulsivity and poor decision-making, and trouble concentrating.
Chronic lack of sleep can be very detrimental to your long-term health. Complications that may arise include:
Heart disease and stroke: Sleep allows your blood pressure levels to temporarily decrease during certain stages of the sleep cycle. Since blood pressure drops during sleep, less sleep means a smaller percentage of your 24-hour circadian cycle is spent in this low blood pressure zone. High blood pressure can be a risk factor for heart disease and stroke.

What Health Conditions Are Linked To A Lack Of Sleep
Adults who sleep less than 7 hours each night are more likely to say they have had health problems, including heart attack, asthma, and depression.3 Some of these health problems raise the risk for heart disease, heart attack, and stroke. These health problems include:
- High blood pressure. During normal sleep, your blood pressure goes down. Having sleep problems means your blood pressure stays higher for a longer period of time.4 High blood pressure is one of the leading risks for heart disease and stroke. About 75 million Americans1 in 3 adultshave high blood pressure.5
- Type 2 diabetes. Diabetes is a disease that causes sugar to build up in your blood, a condition that can damage your blood vessels. Some studies show that getting enough good sleep may help people improve blood sugar control.6
- Obesity. Lack of sleep can lead to unhealthy weight gain. This is especially true for children and adolescents, who need more sleep than adults. Not getting enough sleep may affect a part of the brain that controls hunger.6
Abnormal Blood Pressure Levels While Sleeping Increase Risk Of Heart Disease Stroke
- Nighttime blood pressure levels that are higher than daytime levels, as well as a pattern of blood pressure rising at night , were associated with higher risk of cardiovascular disease and heart failure.
- Even when blood pressure is well controlled during the day, patients who experienced extreme dips in their blood pressure while asleep had a significantly greater risk of stroke compared to those who had normal blood pressure while sleeping.
- Management of blood pressure while sleeping should be a key consideration for health care professionals to help optimize patient outcomes.

DALLAS, Nov. 2, 2020 People who experience high blood pressure while sleeping are more likely to experience future cardiovascular disease especially heart failure, even when their daytime blood pressure is within normal ranges, according to new research published today in the American Heart Associations flagship journal Circulation.
Health care professionals typically use in-office and daytime blood pressure measurements to determine a patients hypertension medication needs and dosages. However, many patients may have undetected nocturnal hypertension high blood pressure while sleeping.

Office Blood Pressure Measurement And Ambulatory Blood Pressure Monitoring
Table reports the Cox proportional-hazard model derived adjusted-HR of CVD outcome calculated on the basis of the baseline OBPM and ABP evaluations per participant. The asleep SBP mean was the most significant BP marker of CVD risk . Interestingly, a greater either morning or pre-awakening BP surge calculated as previously defined was significantly associated with lower, not higher, CVD risk , a finding consistent with the highly significant association between greater sleep-time relative BP decline and attenuated risk. The merit of the asleep SBP mean as marker of CVD risk was highly significant independent of absence/presence of hypertension therapy at baseline or treatment-time schedule during follow-up, i.e. for hypertensive participants of the awakening vs. bedtime-treatment-schedule groups analysed separately. The same conclusions regarding the significantly greater value of asleep SBP as risk marker were also obtained from analysis of total events as outcome variable.
Table reports the HR of CVD based on OBPM and ABPM of the final evaluation. The findings are similar to those described above for the corresponding baseline evaluation , thereby providing further evidence for the greater value of the asleep BP mean and sleep-time relative BP decline compared to any of the other ABP characteristics analysed separately as potential individual markers of CVD risk .

How Low Is Too Low For Oxygen While Sleeping
Oxygen levels are considered abnormal when they drop below 88%. These might be deemed to be severely abnormal when the levels drop below 80%. When the oxygen levels are low for more than five minutes during the night, this is a condition called hypoxemia.
Symptoms of low blood oxygen levels
- shortness of breath.
What Are The Stages Of Sleep
The term sleep architecture refers to the physical structure of your sleep cycle. The sleep cycle of a healthy adult consists of four distinct stages. The first three stages are considered non-rapid eye movement sleep, and the last stage is considered rapid eye movement sleep.
Overall, each sleep cycle usually lasts between 90 and 120 minutes. The duration of each stage largely depends on your age, since people spend less time in REM sleep as they get older.

Does Your Blood Pressure Change While You Sleep
When youre asleep your blood pressure is generally lower than while youre awake. This is totally normal and is known as nocturnal dipping. The drop in both your systolic and diastolic blood pressure can be up to 20% lower than your readings in the day time.
People who dont have lower blood pressure while they sleep have been shown to be at higher risk of heart disease and stroke.
When And How To Measure Blood Pressure
Regular use of a home blood pressure monitor can help people better understand their blood pressure fluctuations. It can also allow people to identify episodes of morning hypertension.
The American Heart Association recommend using a cuff-style blood pressure monitor. These monitors are more reliable than monitors that attach to the finger or wrist.
The AHA also provide the following guidelines for measuring blood pressure at home:
Before measuring blood pressure:
- Rest comfortably and quietly for 5 minutes before measuring blood pressure.
- Avoid smoking, drinking alcohol, or exercising within 30 minutes of measuring blood pressure.
When measuring blood pressure:

How Can Lack Of Sleep Affect Your Health
A night of bad sleep can affect your mood and concentration the next day, but it wont affect your overall health. But a regular lack of sleep can have a bigger effect. In the long run, youre more likely to become overweight or obese and develop problems including high blood pressure, diabetes and heart disease.
How can lack of sleep affect your blood pressure?Many studies have shown people who have trouble sleeping are more likely to have high blood pressure. Sleeping less than five hours a night, insomnia and interrupted sleep all appear to raise blood pressure. This effect seems to be stronger in women than in men, and during middle-age.
How can shift work affect your blood pressure? Shift work can be very disruptive to your sleep patterns and how much sleep you get. There is research linking shift work to health problems including being overweight, high cholesterol and diabetes, and it could raise your blood pressure too.
How Does Sleep Apnea Treatment Affect Blood Pressure
There are a number of treatment options for OSA. Treatment not only improves sleep quality but could also help manage hypertension. The most common and effective treatment is called continuous positive airway pressure .
CPAP treatment involves wearing a facemask attached to a machine that pumps air into the lungs at night. It works by preventing the airway from collapsing, which improves sleep quality in people affected by OSA. Studies investigating the effects of CPAP in patients with hypertension and OSA have shown that treatment with CPAP lowers blood pressure during the day and at night, especially in patients with severe OSA. CPAP also reduces catecholamine levels.
Some patients have a hard time adjusting to the CPAP facemask at night. Consistent, proper use of CPAP is important in order to effectively manage OSA and hypertension. Mouthpieces are one alternative to CPAP and are designed to help maintain an open airway during sleep. Research is needed to determine if mouthpieces also lower blood pressure in people who experience high blood pressure and OSA. Certain surgical procedures are also done to treat OSA in selected patients.

What Is The Connection Between Sleep Apnea And High Blood Pressure
Sleep apnea, or obstructive sleep disorder, causes a reduction of airflow while you sleep the most tell tale sign is snoring, as well as gasping for air, waking up frequently, and chronic daytimefatigue.
A national multi sleep study of over 6,000 men and women, conducted through the John Hopkins School of Public Health found a correlation between high blood pressure and sleep apnea. While more severe sleep apnea, with over 30 lapses in breathing, presents the highest risk, this sweeping study found that even modest sleep apnea is associated with an increased risk of high blood pressure.
How Is Resistant Hypertension Treated
Treatment options for resistant hypertension or pseudo-resistant hypertension depend on your underlying conditions and how well you tolerate various medications. Treatments include:
- Addressing any conditions that may have caused the hypertension.
- Making lifestyle changes
- Adjusting medications to find your optimal type and dosage
