Sleeping less than seven and a half hours per day may be associated with future risk of heart disease, according to a new article. In addition, a combination of little sleep and overnight elevated blood pressure appears to be associated with an increased risk of the disease
"Reflecting changing lifestyles, people are sleeping less in modern societies," according to background information in the article. Getting adequate sleep is essential to preventing health conditions such as obesity and diabetes as well as several risk factors for cardiovascular disease including sleep-disordered breathing and night-time hypertension (high blood pressure).
Kazuo Eguchi, M.D., Ph.D., at Jichi Medical University, Tochigi, Japan, and colleagues monitored the sleep of 1,255 individuals with hypertension (average age 70.4) and followed them for an average of 50 months. Researchers noted patients' sleep duration, daytime and nighttime blood pressure and cardiovascular disease events such as stroke, heart attack and sudden cardiac death.
During follow-up, 99 cardiovascular disease events occurred. Sleep duration of less than 7.5 hours was associated with incident cardiovascular disease. "The incidence of cardiovascular disease was 2.4 per 100 person-years in subjects with less than 7.5 hours of sleep and 1.8 per 100 person-years in subjects with longer sleep duration," the authors write.
Patients with shorter sleep duration plus an overnight increase in blood pressure had a higher incidence of heart disease than those with normal sleep duration plus no overnight increase in blood pressure, but the occurrence of cardiovascular disease in those with a longer sleep duration vs. those with a shorter sleep duration was similar in those who did not experience an overnight elevation in blood pressure.
"In conclusion, shorter duration of sleep is a predictor of incident cardiovascular disease in elderly individuals with hypertension," particularly when it occurs with elevated nighttime blood pressure, the authors note. "Physicians should inquire about sleep duration in the risk assessment of patients with hypertension."

Sleeping Tips
Sleeping Tips
1. Go to bed and get up at about the same time every day, even on the weekends. Sticking to a schedule helps reinforce your body's sleep-wake cycle and can help you fall asleep more easily at night.
2. Don't eat or drink large amounts before bedtime. Eat a light dinner at least two hours before sleeping. If you're prone to heartburn, avoid spicy or fatty foods, which can make your heartburn flare and prevent a restful sleep. Also, limit how much you drink before bed. Too much liquid can cause you to wake up repeatedly during the night for trips to the toilet.
3. Avoid nicotine, caffeine in the evening. These are stimulants that can keep you awake. Smokers often experience withdrawal symptoms at night, and smoking in bed is dangerous. Avoid caffeine for eight hours before your planned bedtime. Your body doesn't store caffeine, but it takes many hours to eliminate the stimulant and its effects.
4. Exercise regularly. Regular physical activity, especially aerobic exercise, can help you fall asleep faster and make your sleep more restful. However, for some people, exercising right before bed may make getting to sleep more difficult.
5. Make your bedroom cool, dark, quiet and comfortable. Create a room that's ideal for sleeping. Adjust the lighting, temperature, humidity and noise level to your preferences. Use blackout curtains, eye covers, earplugs, extra blankets, a fan or white-noise generator, a humidifier or other devices to create an environment that suits your needs.
6. Sleep primarily at night. Daytime naps may steal hours from nighttime slumber. Limit daytime sleep to about a half-hour and make it during midafternoon. If you work nights, keep your window coverings closed so that sunlight, which adjusts the body's internal clock, doesn't interrupt your sleep. If you have a day job and sleep at night, but still have trouble waking up, leave the window coverings open and let the sunlight help awaken you.
7. Choose a comfortable mattress and pillow. Features of a good bed are subjective and differ for each person. But make sure you have a bed that's comfortable. If you share your bed, make sure there's enough room for two. Children and pets are often disruptive, so you may need to set limits on how often they sleep in bed with you.
8. Start a relaxing bedtime routine. Do the same things each night to tell your body it's time to wind down. This may include taking a warm bath or shower, reading a book, or listening to soothing music. Relaxing activities done with lowered lights can help ease the transition between wakefulness and sleepiness.
9. Go to bed when you're tired and turn out the lights. If you don't fall asleep within 15 to 20 minutes, get up and do something else. Go back to bed when you're tired. Don't agonize over falling asleep. The stress will only prevent sleep
