Under the spotlight: Cortisol

Think of cortisol as your body’s alarm system. It’s the main stress hormone which helps fuel your body’s fight or flight response in emergencies. Cortisol works with certain parts of the brain to help control your mood, motivation and fear responses. What does cortisol do? Triangle-shaped hormones called the adrenal glands make cortisol.

These include: Managing how your body uses carbohydrates, fats, and proteins. Acting as an anti-inflammatory when needed. Regulating your blood pressure. Increasing your blood sugar (glucose).

Why you need to watch your blood pressure

Did you know, that your blood pressure never stays the same? It lowers as you sleep and rises when you’re awake, active, excited and nervous.

Salt has long been labelled a hypertension villain, but the link between the two isn’t so clear-cut, a new study finds. The recommended daily sodium intake is 2 300 milligrams. This is equal to about five grams (one teaspoon) of salt per day. However, findings from a 16-year study call this into question. The scientific findings Lynn L.

Your body is an ingenious machine. And, one of the reasons it works so well is because your blood pressure fluctuates. Blood pressure is the force exerted by your heart, against the resistance created by the arteries, to keep blood flowing through your body. Blood pressure measurement consists of two parts – systolic and diastolic. The first number is the systolic blood pressure; this is the highest pressure when your heart pushes the blood around your body. The second/bottom number is diastolic.
