Welcome to the HPRC Blog. We've got lots of information here, from quick tips to in-depth posts about detailed human performance optimization topics.
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.

Godi International, Corp., located in South Florida is announcing a recall of Fruta Planta weight loss dietary supplements because the products contain Sibutramine an undeclared drug ingredient. Sibutramine is an FDA approved drug used as an appetite suppressant for weight loss. This poses a potential threat to consumers because Sibutramine is known to substantially increase blood pressure and/or pulse rate in some patients and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias or stroke.

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!
Social relationships are good for your physical health! According to a recent Science Daily article, relationships improve your chances of living by up to 50 percent. Recent research found that increased interaction with others is similar to avoiding behavioral health risks such as smoking, alcohol abuse, physical inactivity, and being obese. Staying connected in meaningful relationships can pay off not only for your social life, but also for your health.
Military families have created unique ways to maintain close communication through deployments and long duty times. Merolla (2010) studied military spouse communication during deployment and found that while deployed, families deal with the stress of being separated well through balancing talk of everyday things (such as routines and everyday information) with deeper more meaningful conversations. Additionally, another key finding was that though there were individual differences – with creativity among couples an asset – couples seemed to benefit from keeping deployment communication similar to nondeployment communication in both planned and spontaneous discussions (Merolla, 2010).

A recent New York Times article reports that scientists are worried about highly caffeinated beverages like Red Bull, Rockstar, Monster and Full Throttle, which are popular among teenagers and young adults. According to the article, the often bizarre combination of ingredients in these drinks prompted three researchers from theHealth Science Center at Houston and the University of Queensland in Australia to examine what is known — and not known — about the contents of these beverages, which are sold alongside sodas and sport drinks in supermarkets, drugstores and highway rest stops.

First lady Michelle Obama called on parents, schools, workplaces and the military to combat America's obesity epidemic in a visit to Fort Jackson this past Thursday. As America's waistline has grown, finding young people fit enough to serve in the military has become a problem, U.S. Army officials told Obama during her three-hour visit.
Ms. Obama is promoting the "Let's Move!" program to combat childhood obesity. And she met with Army personnel, from privates to a three-star general, to find out how the military is dealing with the problem and how solutions might be transferred to the general population.

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.

The way that parents behave under stress, and interact with their children on a daily basis, has a profound influence on a child’s resilience or the ability to bounce back from stress. Parents can improve resilience by teaching the following skills to their children:
- Spiritual: Parents can help children feel a sense of uniqueness, purpose, and perseverance by providing a spiritual foundation, framework, or belief in something bigger than just the child’s universe.
- Emotional: Parents can model and foster positive mood management; discuss feelings with them and help them learn how to deal with emotions, both positive and negative.
- Physical: Parents can practice and teach positive health habits that include healthful food choices and physical activity.
- Behavioral: Parents can model, coach, and teach positive behaviors that help foster their child’s belief that they can behave well and make positive choices.
- Cognitive: Parents can enhance a child’s self-esteem and help them develop cognitive and academic skills by monitoring and checking their homework, and promoting problem solving skills that teach them to proactively solve problems and develop independent thinking skills.
