Insufficient sleep increases blood
pressure at night
Chronic sleep deprivation can increase night time
blood pressure, putting you at greater risk of heart diseases, warns new
research.
"For the first time, we demonstrated that insufficient sleep causes increases in night time blood pressure and dampens nocturnal blood pressure dipping," said lead author Naima Covassin from Mayo Clinic in the US.
The results stemmed from a controlled study that mimicked the sleep loss experienced by many people.
"We know high blood pressure, particularly during the night, is one of the major risk factors for heart disease," Covassin said.
In this study, eight healthy normal weight participants aged 19 to 36 participated in a 16-day in-patient protocol consisting of a four-day acclimation period followed by nine days of either sleep restriction (four hours of sleep per night) or normal sleep (nine hours of sleep per night), and three days of recovery.
Twenty four blood pressure monitorings at regular intervals were measured at each study phase.
During night time, in the sleep restriction phase compared to normal sleep phase, systolic (top number) and diastolic (bottom number) blood pressure averaged 115/64 millimeters of mercury (mm Hg) versus 105/57 mm Hg respectively, researchers found.
Furthermore, the expected fall in blood pressure during the night was suppressed when the people had inadequate sleep.
They also found that night time heart rate was higher with sleep restriction than in normal sleep.
The findings are scheduled to be presented at the American College of Cardiology's 64th Annual Scientific Session in San Diego on March 15.

Signs your blood sugar is on the higher side
If you have a history of fluctuating sugar levels
or diabetes in your family, it is best to go in for a simple blood sugar test
twice a year. You also need to keep an eye out for these signs...
- Do you feel thirsty all the time? Constant thirst and visiting the washroom repeatedly can indicate that there is a lot of sugar in your blood. This puts more pressure on your kidneys to remove the sugar and while doing that, they use fluids from your body's tissues. This, say experts, cases frequent urination. And when you're visiting the bathroom often, you also feel thirsty and end up drinking more water so that you don't get dehydrated.

- Another classic sign of too much blood sugar is feeling tired all the time. Too much sugar in your blood means that your cells aren't getting enough and that in turn affects your muscles. This is what causes fatigue.
- Another sign of diabetes is swelling or numbness in the hands and feet. Get yourself checked by your doctor.
- Regularly suffer from stomach problems? It could be that your blood sugar levels are on the higher side. Another indication is failing eyesight. High blood sugar can cause damage to your eyes and cause a change in your eye number. Do you suffer from blurred vision or see spots or lines in front of you? Time to get your blood and eye test done.
- Unexplained weight loss is also a sign that something isn't right. Neither is the fact that any infection you catch takes time to go away or a cut takes time to heal.
