Drink more water for a strong heart

Drinking more water may reduce the risk of heart failure

If you forget to bring a water bottle to work, you are not alone. I have clients that always come to their workouts with water, and clients that never do. There’s no definitive answer as to how much water you need, but many of us aren’t drinking enough of it. While guidelines vary, generally women need between six to eight cups, and men need approximately eight to 12 cups. It depends on many factors, including your health, how active you are and where you live.

Water makes up approximately 50-70% of our body weight. It keeps our temperatures normal, cushions joints, protects our spinal cord, flushes bacteria from the bladder and carries nutrients and oxygen to our cells. Getting enough fluids also normalizes blood pressure and stabilizes the heart. It’s important to stay hydrated, as everyday we lose water through breathing, sweating and peeing.

New studies by researchers at the National Institute of Health suggest that staying well hydrated not only supports essential health, but may also reduce the risk of heart failure or long-term risks for heart disease. Heart failure is a chronic condition that happens when the heart does not pump enough blood for the body’s needs.

Approximately 11,814 healthy adults were in the final study. Of those, 11.56% later developed heart failure. To assess possible links with hydration, researchers analyzed levels of serum sodium. Serum sodium increases as the body’s fluid levels drop, and helped identify older adults with an increased risk of developing either heart failure or left ventricular hypertrophy, an enlargement and thickening of the heart. Higher serum-sodium levels at middle age showed a 102% increased risk for left ventricular hypertrophy and a 54% increased risk for heart failure.

All beverages, even coffee or alcohol, contribute to hydration. A Harvard Medical School Special Health Report notes that it is a myth that caffeinated drinks or alcohol are dehydrating because they make you urinate. They do, but over the course of a day, the water from these beverages still lead to a net positive contribution to total fluid intake.

Of course, water is still the best option, as sugary drinks can lead to weight gain and inflammation. Caffeine, for some, can give you the jitters or keep you from sleeping. And alcohol intake, research suggests, should be limited to one drink per day for women, and one-to-two drinks per day for men.

You can also get fluids from water-rich foods, such as salads and fruit. Aim to have water throughout the day and water at each meal, as well as socially.

Remember that thirst is not an indicator of hydration. Signs that you are dehydrated are less frequent urination, dark-colored pee, fatigue, confusion or dizziness. Drink for health.

Sleep Matters

Sleep Matters

Sleep. We barely give it thought, until we can’t, yet it is fundamental for health and productivity. We spend approximately one third of our lifetime asleep, crucial time  when the brain recharges, and goes to work consolidating the days learning into memory. Except for babies and children, our need for seven to eight hours of sleep each night doesn’t change throughout our lives, but our sleep patterns do, as anyone wide awake at three in the morning knows. An older adult who goes to bed earlier and wakes up earlier might nap more during the day . A teenagers’ biological clock keeps them awake later in the evenings and sleepier early mornings. Biological conditions unique to women: menstrual cycles, pregnancy, and menopause can wreck havoc on sleep. A recent National Sleep Foundation poll of adults revealed that women are more likely than men to have difficulty falling asleep and staying asleep. Forty million Americans  suffer from sleep disorders. Yet what happens during sleep is stunning.A new sleep study conducted by monitoring the brain waves of 6-10 year olds sleeping shows that the brain goes through a remarkable amount of reorganization during puberty that is necessary for complex thinking.

There is an even more compelling reason for a good night’s sleep for your well-being. People who sleep poorly and less than six hours have a 65% higher risk of dying from a heart attack or stroke compared to sound sleepers who are getting seven-eight hours. This didn’t apply to sound sleepers getting only six hours who wake up feeling fit and rested. The research from Wageningen University and the National Institute for Public Health and the Environment is based on 20,000 people, with a ten and fifteen year follow-up. The Dutch study, published last week, showed that if you eat well, don’t smoke, drink moderately, and are physically active the risk of dying from heart disease is lowered by a staggering 83 %. (Adding only one of these positive lifestyle factors lowers the chance of developing heart disease by 57%.)

Until recently it was unclear why we eat more when we don’t get enough sleep. Just getting less sleep doesn’t mean you will gain weight, but a recent study done at the University of Colorado and published in the Proceedings of the National Academy of Science  showed the participants sleeping up to five hours a night ate a smaller breakfast but binged on after-diner snacks. : “When people are sleep restricted, the findings show they eat during their biological nighttime when internal physiology is not designed to be taking in food”, says Kenneth Wright, director of CU Boulder Sleep and Chronobiology Laboratory. Nighttime eating was well over the amount of calories than any other meal consumed. These findings add to the growing body of evidence that late night eating certainly can add unwanted weight.

Here are some tips from the National Sleep Foundation intended for “typical “ adults, but not necessarily for people with specific medical problems, when consulting with your doctor would be the best approach.

1.Go to bed and wake up at the same time including weekends. Our internal clock is regulated by a circadian rhythm that all living beings have-roughly  a 24-hour cycle. It rises and falls at different times of the day, depending on whether you are a “morning person” or “evening person” Getting enough sleep ensures the dips are less intense

2. Establish a relaxing nighttime ritual. A hot bath is a better idea than paying bills. Try to wind-down away from computers, or bright lights. The brightness stimulates neurons that help control the sleep-wake cycle that it is time to shine, rather than snooze.

3. Create an environment that is dark, quiet and cool. A quiet environment free of interruptions makes your bedroom reflective of the value you place on your sleep. If your partner snores, try earplugs. Eyeshades or a humidifier can help with light or dry temperatures.

4. Sleep on a comfortable mattress and pillows. If your mattress isn’t comfortable and supportive, it may be time for a new one, as the life expectancy is about 9-10 years. Also check for allergens that might affect you.

5. Finish eating at least 2-3 hours before bedtime. Eating and drinking too close to bedtime might make you feel uncomfortable.

6 . Exercise regularly. Vigorous exercise, or any at all, is better than no activity, but not at the expense of your sleep.

7. Avoid caffeine ( coffee, tea, chocolate ) and alcohol close to bedtime. It can keep you awake. Caffeine sensitivity can vary widely: it takes between four and seven hours for half of the stimulant to leave your body, making it harder for you to wind down. Although many people think of alcohol as a sedative, it  actually disrupts sleep and leads to a night of less restful sleep.

Recharging sounds like a great idea. Sweet dreams tonight.
