The amount of the time spent sleeping is decreasing: the average amount of sleep reported for middle-aged people in the late 1050s—around eight to nine hours—has decreased in recent times to about seven or eight hours. And the number of individuals who sleep less than six hours each night has significantly increased. These changes in sleep patterns may be indicative of sleep deprivation in society at large. This is not surprising, as the modern society seems to offer twice as much work (on the job, at home, etc.) and half as much time to complete it. Consequently, we are awake for extended periods of time, thus reducing the amount of time we spend sleeping.
However, we all know that sleep is essential! Sleep is vital to restore and renew many body systems; and sleep deprivation may result in poor performance, increased sleepiness, reduced alertness, delayed response time, difficulty maintaining attention, decreased positive mood, and increased long-term health risks. Some research studies have even shown that sleep deprivation is associated with increased risk of death.
So adequate sleep is vital for everyone to optimally perform the activities of daily living. But you may wonder, “How can I determine how much sleep I need to function at my best?” Dr. Michael Bonnet, director of the Sleep Laboratory at the Dayton. Ohio, Department of Veterans Affairs Medical Center provides a very simple but practical test you can use to determine how much sleep you need. According to him, if you need an alarm clock to wake up, try going to bed a little earlier the following night (e.g., 15 minutes earlier). If you still need an alarm clock to wake up the next morning, push your bedtime a little earlier again (i.e., another 15 minutes). Continue doing this until you no longer need an alarm to wake up.
I actually tried this test and found out I was not the “night owl” I thought I was. It looks like I function at my best if I retire for the night a couple of hours earlier than I used to. Sleep is important! It significantly affects your performance, health, and quality of life. And it is especially important to Warfighters, who can rarely get enough when deployed. So in addition to a healthy diet and regular exercise, try to get enough sleep each night whenever your situation makes it possible.

Your body needs calcium for optimal bone health and a number of other functions essential to daily life. Good food sources include: fat-free or low-fat milk, cheese, and yogurt; leafy greens such as spinach and kale; and broccoli, and pinto and red beans. Many other foods such as high fiber cereal, soy beverages, and orange juice are fortified with added calcium. Adding these foods to your diet will improve not only your calcium intake, but many other nutrients as well!
Being in stressful situations activates the body’s physiologic stress response, which is what allows Warfighters the ability to respond to any threat at any time. In the sports world, the stress response is associated with the adrenaline rush that pumps athletes up during competitions, and gives them the edge to win.
Unlike athletes, however, Warfighters are a select group who operate in stressful situations day in and day out. Prolonged exposure to stressful situations has been found to be harmful both physically and psychologically, unless one learns how to successfully manage one’s internal response. To that end, there are programs throughout the uniformed services that teach Warfighters combat stress management techniques. Many use a stoplight system—utlizing the colors green, yellow, and red—to teach Warfighters how to calm the stress response and bring the body back into balance, in order to give it a reprieve. Successful warfighters learn these skills and apply them in theater.
These same skills, which allow one to calm the body’s physiologic response to stress, can also be applied to other areas—most notably, in one’s relationships. The stress response triggered by external threats is the same stress response that is activated during emotionally-charged conflicts with someone you care about (although the degree of stress is different). Conflict between two people creates the same internal stress, coupled with a flood of negative emotions. The techniques learned to manage combat stress are techniques that can also help Warfighters in their personal relationships.
A recent study examined 149 couples in a 15-minute discussion about a marital conflict found that positive emotions helped couples regulate, or calm, their physiologic responses after the conversation. Interestingly, how happy the individual was with their relationship did not impact this finding. This indicates that positive emotions seem to have the ability to “undo” the physiologic arousal of conflict.
The next time you get in a fight with someone you care about, try this: stop, take yourself out of the situation, and start thinking positive thoughts—either about yourself, something else, or your partner. Notice whether you feel calmer, if your body temperature decreased, if your heart rate slowed down, and if your body moved less (we tend to move more when we are upset). You might find this to be an excellent addition not only to your combat stress strategies, but also to your positive relationship strategies.

Foodborne illness, commonly known as food poisoning, can make you feel as if you have the flu! Symptoms often include nausea, vomiting, diarrhea, or fever. It’s caused by consuming foods or beverages contaminated with bacteria, parasites, or viruses. To prevent, wash your hands and surfaces; cook foods to proper temperatures; and refrigerate cooked foods promptly. For more helpful tips, click here.

To keep your cholesterol in check, eat smaller portions, include more fruits and vegetables in your diet, and eat more fish. Consider starting your day with whole grains. Include nuts as snacks or in your meals. Use olive or canola oil rather than butter. Include more beans and fewer potatoes. Exercise, manage your stress, and follow your doctor’s advice. Check out the Lowering Cholesterol Slideshow for more details.
Although salt is an essential nutrient, very little is needed in the diet. High-salt diets are associated with increased blood pressure and higher risk for heart disease and stroke. Reduce your intake by using fresh or frozen vegetables not canned; cooking with fresh meat, fish, and poultry rather than processed or canned; and using salt-free seasonings, spices, and herbs. Avoid instant and prepackaged foods. If you do eat canned foods, rinse the contents to wash off excess salt. Read these links for more ideas: HealthDay News and American Heart Association.
According to researchers at Northwestern University, regular exercise may improve your sleep quality and mood. They studied two groups: one that exercised four times per week for 16 weeks, and one that took part in recreational and educational activities but did not exercise. Participants who exercised reported that their sleep quality improved. They also reported fewer depressive symptoms, more vitality, and less sleepiness in the daytime. Sleep is important to good health, so stay physically active to improve your sleep quality and mood! Read HealthDay News for more details.
Eggs are a good source of protein but the yolks are high in cholesterol; egg whites are cholesterol-free. A diet high in cholesterol may contribute to high blood cholesterol levels and increase your risk of heart disease. Experts recommend that you limit your cholesterol intake to less than 300 mg a day if you are a healthy individual and less than 200 mg a day if you have heart condition. Since one egg has about 213 mg of cholesterol, consider limiting other sources of cholesterol on days you eat eggs. The Mayoclinic offers tips to reduce cholesterol intake.
