How might switching to daylight saving time affect your health?

WASHINGTON (AP) – Most of America “wakes up” on Sunday for daylight saving time, and losing that hour of sleep may do greater than just make you drained and grumpy the subsequent day. It might also harm your health.

Darker mornings and more evening light mix to disrupt your body clock, which implies daylight saving time may cause sleep problems for weeks or longer. Studies have even shown a rise within the variety of heart attacks and strokes immediately after the March time change.

Hawaii and most of Arizona don’t make a spring change, sticking to standard time year-round, as do Puerto Rico, American Samoa, Guam and the U.S. Virgin Islands. Around the world, dozens of nations also observe daylight saving time, starting and ending on different dates.

Some people try to prepare for the shock of Daylight Savings Time by going to bed a little bit earlier two or three nights before. With one-third of American adults now not getting the really useful seven hours of sleep an evening, it might be difficult to catch up.

This circadian rhythm is a roughly 24-hour cycle that determines once we turn out to be sleepy and once we are more alert. Patterns change with age, which is one reason why early-maturing children turn out to be difficult-to-awaken teenagers.

The morning light resets the rhythm. In the evening, levels of a hormone called melatonin begin to rise rapidly, causing drowsiness. Too much light within the evening – that extra hour from daylight saving time – retards this growth and the cycle gets out of sync.

Lack of sleep has been linked to heart disease, cognitive impairment, obesity and lots of other problems. And this circadian clock affects not only sleep, but additionally heart rate, blood pressure, stress hormones and metabolism.

Doctors already know that heart attacks, especially severe ones, occur barely more often on Mondays and within the morning, when the blood is more susceptible to clots.

It’s unclear why Monday’s call can be affected by the time change, Sanchez said, although there’s likely something concerning the sudden disruption of circadian rhythms that exacerbates aspects akin to hypertension in people already in danger.
