As we go through the day our blood pressure just naturally raises and lowers depending on a lot of conditions. What most people are most interested in is a regular resting blood pressure as high blood pressure and hypertension are a very strong indicator toward present and future heart problems

The Effect Of Sleep on Blood Pressure

Sleep causes a fall in blood pressure. The maximum depth occurs about two hours after falling asleep. In sound, untroubled slumber a pressure of 130/80 might dip to 100/70. It once was thought that this drop in pressure was the cause of sleep, the reasoning being that a lower pressure delivers less blood to the brain resulting in mental sluggishness and hence sleep. Now it is known that this blood pressure decline is the result, not the cause, of sleep. As morning approaches, the blood pressure drifts slowly upward as the subject begins the awakening process. Any interference with sound sleep causes the blood pressure to rise. Read the rest of this entry »

eDiets has an article telling us what fit people do. It is right on the mark

1. Sleep well and wake up naturally. Many fit people arise without an alarm clock feeling energized, rested and hungry. They have set fitness goals and a plan to achieve them. People who are fit fall asleep easier, have more quality sleep and require less sleep than someone who is unfit. Lack of sleep is strongly associated with obesity. Sleeping helps the body repair, rebuild and recover.

2. Get prepared. Fit people pack their gym bags the night before, have clothes laid out for exercise, toiletries packed for a shower, clothes for work and an appointment in their planner for physical activity. They regard their workout appointments as highly as any other business or social commitment. Read the rest of this entry »

The amount of physical exercise that you exert during the day is one of the key ingredients to helping you get a good sleep at night. The more active your body is during the day, the more likely you are to relax at night and fall asleep faster.

With regular exercise you’ll notice that your quality of sleep is improved and the transition between the cycles and phases of sleep will become smoother and more regular. By keeping up your physical activity during the day, you may find it easier to deal with the stress and worries of your life.

Research and studies indicate that there is a direct correlation between how much we exercise and how we feel afterwards. You should try and increase your physical activity during the day. The goal here is to give your body enough stimulation during the day so that you aren’t full of energy at night. Your body requires a certain amount of physical activity in order to keep functioning in a healthy manner. It is also important to note that you should not be exercising three or four hours before you go to bed.

The ideal exercise time is in the late afternoon or early evening. You want to make sure you expend your physical energy long before it is time for your body to rest and ready itself for sleep. You should attempt to exercise at least three or four times a week for a period of 30 minutes or so. Read the rest of this entry »

In a paper published in The Journal of Physiology, Helge, Stallknecht, Richter, Galbo, and Keins from Copenhagen shed light on fat oxidation during exercise and physical activity. Their observations suggest that fat oxidation during exercise reflects a fine interplay between the cardiovascular, neurological, endocrine and muscle metabolic systems.

During exercise and physical activity, the primary fuels used by muscles are carbohydrate and fat. When mild exercise is performed there is a tendency to burn relatively more fat and less glucose, but as exercise becomes more intense, a higher fraction of the energy demands of the muscle are supplied by glucose, until at the highest intensities almost only carbohydrates are used. Is this shift in fuel source a property of the muscle itself, or does it represent the interplay between what is happening in the muscle and the exercise-related responses in the rest of the body”

The study, performed at the Copenhagen Muscle Research Centre at the University of Copenhagen, examined muscle fuel utilisation in response to graded exercise performed with only one leg. Nine healthy males performed one-leg exercise at 25, 45, and 85% of maximal workload. Their results showed that, when only a small mass of muscle is contracting, and blood flow and oxygen supply are not limited by central circulatory capacity, the shift in fuel source from fat to glucose as exercise intensity increases does not occur.

The Journal of Physiology findings show that the adaptations in the rest of the body are the key to this fuel source shift during whole body exercise. They also help scientists understand why athletes “hit the wall” during events like the marathon, and they have implications for the adaptations made in middle-aged adults who are using exercise to prevent or treat conditions like diabetes and obesity. If the mechanisms can be fully understood, it may be possible to develop agents that allow fat oxidation to be maintained even during intense exercise with a large muscle mass.
