The distance of a light year. How long would it take the space shuttle to go one light-year? The shuttle orbits the Earth at about 5 miles per second (18,000 mph). Light travels at 186,000 miles per second, which is about 37,200 times faster than the shuttle. So the shuttle would need about 37,200 years to go one light-year.
Periods of anxiety trigger the release of hormones that cause increased heart rate and decreased blood vessel diameter, both of which lead to increased blood pressure. 1  The effect of stress on short term blood pressure can be dramatic, leading to mean arterial pressure increases of 30%-40%. These changes are short lived, though, with heart rate, blood vessel diameter, and blood pressure returning to normal as the hormones are eliminated.
Chronic (constant) stress causes our bodies to go into high gear on and off for days or weeks at a time. The links between chronic stress and blood pressure are not clear and are still being studied.
