Skipping Breakfast Can Increase Your Stroke Risk

Mar 08 by Ewcopywriting Leave a Comment

Who has time for breakfast? In the modern world, many people succumb to the morning rush and run out the door with empty stomachs. However, this can have a negative effect on health in a variety of ways. People who skip breakfast tend to have lower cognition and poorer memory. A new study suggests that skipping the most important meal of the day can even increase stroke risk.

Blood Pressure and Stroke Risk

Health care workers and scientists have long acknowledged the link between blood pressure and stroke risk. In fact, there is a direct relationship between the two. High blood pressure can cause clots to break free from blood vessel walls and lodge in the delicate vessels of the brain, causing a lack of blood flow to key areas and a resulting loss of function, also known as an ischemic stroke. High blood pressure can also cause a hemorrhagic stroke, also known as a brain bleed, when the high pressure causes cerebral blood vessels to rupture.

Circadian Rhythm, Blood Pressure, and Breakfast

How can skipping breakfast contribute to stroke? While a recent study has confirmed that there is a connection, it seems to be counter-intuitive at first look. However, researchers believe that high blood pressure may be the link. Skipping a meal ultimately results in a rise in blood pressure. Because blood pressure is naturally higher in the morning, people who skip breakfast ultimately may end up with dangerously high blood pressure. The result is damage to blood vessels and a 30 percent rise in stroke risk.

Circadian Rhythm, Hypertension, and Health

Skipping Breakfast Can Increase Your Stroke RiskUnderstanding the circadian rhythm can help people to reduce their disease risk. Our bodies create hormones and other important cell proteins on a 24-hour cycle. Understanding this cycle and its effects on our bodies can help people to make better health decisions. While few people would think that eating breakfast affects their disease risk, it indeed appears to be the case. It is important to eat breakfast because it helps us to think better and function better throughout the day, but also because it keeps blood pressure from spiking, thus prevents stroke risk from soaring.

Living With Your Circadian Rhythm

Our bodies are designed to live according to a 24-hour rhythm. While modern life often interferes, it is important to keep healthy habits. There is a reason our ancestors believed in eating a healthy breakfast, even if they could not perform double-blind studies on every benefit. They understood on some innate level that our bodies were intended to work on a 24-hour cycle.

Research in chronobiology is constantly helping people to understand their bodies better and thus to reduce the chances of developing deadly disorders such as stroke. Your healthy breakfast is not just a great way to start a productive day, but a way of reducing your disease risk as well.

Take Your Blood Pressure Medication Before Bed for Best Results

Jan 22 by Ewcopywriting Leave a Comment

A new study finds blood pressure medication may be more effective and even prevent death due to cardiovascular disease when taken at night.

Treating hypertension, or high blood pressure, is a challenge for many health care workers. While there are many medications available, it can be difficult to find the right combinations and doses that will keep blood pressure under control with minimum side effects. A new study suggests that the time when people take their blood pressure medication may be an important factor in hypertension control.

What Causes Hypertension?

There are several causes of hypertension. As people age, many develop atherosclerosis, or hardening of their blood vessels. This keeps their vessels from stretching to accommodate changes in blood volume, which leads to higher pressure in the circulatory system. Second, many people also develop lipid deposits in their arteries as they age, which further constricts their blood vessels and raises pressure.

One last and highly-treatable factor in blood pressure is the Renin-Angiotensin-Aldosterone System, or RAAS. This system releases hormones that control the excretion of fluids and electrolytes. Retaining fluid and electrolytes as a result of abnormal activity in the RAAS is a major cause of hypertension. For this reason, this system is the target of the most commonly-used classes of blood pressure medication, including ACE inhibitors and angiotensin receptor blockers (ARBs).

The Timing of Blood Pressure

Resized_Blood_Pressure_256145749The RAAS is tightly-timed and runs on a circadian rhythm, which means that hypertension also has a distinct 24-hour cycle. In a healthy person, blood pressure rises shortly before waking as the RAAS goes into high gear. It reaches a peak around noon and then slowly falls until bedtime. It reaches an all-time low when people finally fall into deep sleep.

However, in people with hypertension, especially hypertension that doesn’t respond to medication, blood pressure fails to fall at night. People with higher nighttime blood pressure, called non-dippers, are more likely to suffer heart attacks and strokes, especially late at night and in the early morning.

Can Timing Blood Pressure Medication Help?

In a recent chronobiology study, people with hypertension were followed for more than five years. Some took their blood pressure medication in the morning, which is typical, while others took it before bed.

The people who took their blood pressure medication at night had lower blood pressure. In addition, they had one-third the amount of heart attacks and strokes. This is not the only study suggesting that taking blood pressure medication at night has health benefits. Another recent study found that people who take their medication at night have a lower risk of developing diabetes, a common complication in hypertensive people.

Chronopharmacology and Health Care

Chronopharmacology, a sub-discipline of chronobiology, is one of the fastest growing fields in medicine. New studies are published almost every week suggesting that when we take medication can have a huge effect on treatment, side effects and even death rates. Circadian rhythms dictate almost every cell process, including how we use and metabolize medications.

One in three adults, or about 70 million Americans, suffer from hypertension. Of these people, only about half have their condition under control. These new studies on chronopharmacology and blood pressure medication offer hope that people may find better control of a difficult-to-treat disease and lead longer, healthier lives.
