Compression garments come in a variety of sleeves, socks, shorts, and full-body suits. The amount of pressure, or compression, they provide depends on the type and size of the garment. Compression garments help push blood toward your heart and prevent it from “pooling” or collecting in the compressed areas. Compression sleeves also are used in clinical settings for those with lymphedema, where blood circulation is poor, or to prevent blood clots.
But can they increase your performance and decrease your recovery times? Compression garments have been shown to help blood flow to working muscles during exercise, but that necessarily doesn’t translate to better performance. Most studies look at compression socks during running, and most evidence suggests no difference in athletes’ performance levels during runs when compared to those not wearing compression socks. In addition, there’s no decrease in recovery time or blood-lactate levels.
Still, those wearing compression socks report “feeling better” and “less tiredness” in their legs during their runs. They also feel less sore following the exercise bout. And while there might not be an actual benefit of wearing compression gear, if you feel better wearing it—either during or after exercise—then keep doing what works!
Creatine supplements are popular among athletes and Warfighters trying to enhance their strength and muscle size. Unlike many other supplements, there is considerable evidence that taking creatine supplements might result in greater gains in body mass and strength when combined with resistance training. However, not all athletes or Warfighters will experience the same benefits from consuming creatine supplements, especially those focused on endurance training. And although there are few safety concerns associated with creatine, it’s still important to use it under the guidance of a healthcare provider. Read more...
While initiation activities have long been a part of military culture, group aggression and hazing contradict the values of dignity and respect championed by the Armed Forces. Group aggression and hazing can put service members at risk of injury and impact team unity.
Aggression is behavior—including any action taken or situation created—that intends to cause harm to someone who doesn’t want to be harmed. Group aggression is the active use of violence by one group against another group. Hazing is an example of group aggression: It’s the act of forcing new team members to endure unsafe, painful, or embarrassing rituals as part of their initiation into a group. Victims experience physical and emotional abuse that goes beyond military-sanctioned ceremonies that build team commitment.
Group aggression is more common than individual aggression. It’s possible that when people feel they’re less identifiable, they’re more likely to be aggressive. For example, you blend in with your teammates and your group might collectively take the blame for any one act—which can feel less punitive then being punished on your own. In addition, aggression often provokes even more bad behavior within groups. Hazing might go unnoticed in the military partly due to its internal hierarchy that can make it hard to identify such hostile acts.
Hazing and group aggression don’t always improve cohesion, bonding, or commitment among teammates. And some victims are at risk of physical trauma, psychological abuse, and even death.
Strong teams are based on respect and dignity, where members feel supported and empowered. Team building should lead to pride in your group and integrity among its members.

Swimmers and free divers who hyperventilate before holding their breath for long periods underwater are at risk of hypoxic blackout—loss of consciousness—that can result in brain damage and death. (It sometimes is known as “shallow water blackout,” but this can be confusing because there are other causes of “shallow water blackout.”)
Hypoxic blackout often affects skilled, fit, and competitive swimmers and free divers. They practice breath holding or hypoxic training in water to increase their ability to hold their breath for longer periods of time. But depending on the technique, this can be a dangerous practice.
Breathing is a process of exhaling carbon dioxide (CO2) and inhaling oxygen. The actual urge to breathe is caused by a buildup of CO2 within your lungs. If you simply try to hold your breath underwater, the physiological urge to breathe will eventually take over so there isn’t a significant risk of “passing out.” However, some swimmers and free divers have found that if they hyperventilate before diving into the water —either by rapid breathing or taking deeper breaths—they can hold their breath for longer periods of time. It’s the act of hyperventilating that can be deadly.
When you hyperventilate before underwater swimming, the amount of CO2 is reduced in your lungs and the urge to breathe is diminished. Without warning, you can lose consciousness—at which point a breath is forced and water fills your lungs. Unless rescue is immediate, brain damage and death are likely outcomes.
Training with instructors and a skilled free-dive or swimming community will help reduce your risk of tragic accidents. In addition, there are other things you can do to avoid hypoxic blackouts.
- Don’t hyperventilate before underwater swimming.
- Never swim alone.
- Don’t ignore the urge to breathe underwater.
It’s almost time to turn the clock back, and for some people, this time of year signals darker days ahead. Shorter days and less exposure to light are no longer thought to directly cause increases in depressive disorders. However, you might still observe noticeable shifts in your mood, behavior, motivation, and even your diet and physical activity routines during this time of year. The increasing darkness and downshift in temperature don’t have to mean the same for your well-being. If falling back is a time you dread, try these tips to create light in the darker days:
- Take care of yourself. Remember that optimal performance requires recovery. Autumn is the perfect opportunity to take time for yourself. Bank some sleep before you have to run around or travel for the holidays. Get in a few extra workouts so you can savor a piece of pie at Thanksgiving dinner without the side of guilt. Rest now so that you can be resilient later.
- Set new SMART goals. You don’t have to wait until the New Year to set resolutions. This is a great time of year to assess the goals you want to work toward in the coming year and begin establishing daily habits early, long before the ball drops in Times Square. Doing an azimuth check now can help to keep you on track through the busy holiday season and reignite a sense of purpose.
- Perspective matters. Some of the reasons why you might feel sluggish and unmotivated during of the change in season are a proxy of your expectations: You think you’re supposed to feel that way, and so you do. Try shifting your lens. Are there things you can look forward to in the winter? Maybe you want to dig into that book you’ve put aside? Break out your snowboard and plan a trip? Focusing on what you’re anticipating rather than what you dread can make a world of difference.
Fall and winter don’t have to become the seasons of your discontent. The grass will be greener when things warm up again, but make sure you take advantage of now to enhance your well-being.
Eating an apple every day might “keep the doctor away,” but apples can be a perfect choice for those who want to eat healthy and perform well. They contain flavonoids, which can help reduce your risk of cancer and heart disease. Apples also can help lower cholesterol and blood glucose, which is especially important for those with diabetes. Trying to lose weight? Apples are good sources of fiber, helping you feel fuller longer.
Unlike most fruits, apples are available year-round and generally less expensive. Since there are over 7,000 varieties in the U.S., you might find some favorites. And remember to eat the peel because it contains valuable vitamins, minerals, and antioxidants.
On average, Americans eat one apple each week. Why not add apples to your daily eating routine?
- Breakfast. Grate and stir into pancake mix or oatmeal for added flavor.
- Lunch. Chop and add to your favorite green salad. Or mix with dried cranberries and chicken or turkey salad.
- Post-workout snack. Enjoy with nut butter to help rebuild muscles and replenish energy stores. Or simply eat one out of hand.
- Dinner. Slice and bake with pork chops for a tasty fall meal. Or add some to your holiday stuffing. Tip: Mix grated green apple with purple-cabbage salad mix, ⅓ cup cider vinegar, and 1 Tbsp sugar for a colorful, crunchy coleslaw.
- Dessert. Core and fill the center with raisins, 1 tsp brown sugar, and a dash of cinnamon. Microwave until soft and then top with vanilla frozen yogurt.
Green coffee bean extract has been available in dietary supplements for quite some time, but despite the hype and popularity of this ingredient, there’s little science to support its use as a weight-loss aid. Green coffee beans are the raw, unroasted seeds or “beans” of the Coffea plant. Similar to your morning cup of coffee, they contain caffeine in addition to a chemical called chlorogenic acid. The difference, though, is that green coffee beans contain more chlorogenic acid because roasting reduces the amount of chlorogenic acid in coffee beans.
Chlorogenic acid supposedly offers some health benefits, but don’t believe everything you hear (or read) about green coffee beans supplements for weight loss; there just isn’t enough evidence to back up these claims. In fact, the Federal Trade Commission (FTC) charged a company for using deceptive weight-loss claims to market a green coffee bean supplement. Read more about this in FTC’s Press Release.
It can be challenging to explain and understand a stepmother’s responsibilities when a new stepfamily is formed, but there are ways to support her “new” parenting role. Stepfamilies form when a child’s mother or father marries someone after his or her relationship with the child’s other parent has ended.
It’s important for stepmothers to build strong relationships with their stepchildren, but this sometimes can be tricky. A stepmother often has to strike a balance between bonding with her stepchildren while also respecting the limitations of not being a biological parent, especially when her stepchildren’s other parent remains active in their lives. Stepmothers sometimes can feel confused about what their roles should be, and this can lead to insecurity. Stepmoms also might feel they’re expected to do many household and childcare tasks even though they’re not considered parents. It can be hard for a stepmother to see her spouse’s involvement with the children—playing a role she’s unable to play—and continued contact with the children’s other parent too. And stepchildren can feel unsure about how their stepmother will fit into their lives.
Still, when stepfamilies live together at least half-time, stepmothers tend to be happier in their marriages and closer to their stepchildren. Successful stepmothers develop a parental mindset and work to define their roles in their new families. In addition, communication that focuses on strong listening skills and avoids criticism or contempt can help a stepmother and her spouse agree on her role and how they’ll support each other as parents and partners.
If you find it difficult to share when you’re feeling down or anxious about something in your life, writing can help you make sense of an experience on your own. It isn’t easy to reach out when you’re going through tough times. You might prefer keeping struggles private or feel that there isn’t anyone you can turn to who might really understand.
Writing about your deepest thoughts and feelings can be an effective tool to help you process your stressful events. Writing can help you direct attention to causes of distress and raise awareness of the impact they have on you—emotional, behavioral, or physiological. By helping you express emotions you might want to suppress or avoid, the process can put distance between you and your thoughts, giving you an opportunity to evaluate or restructure your story.
Writing also can help reduce depressive symptoms, improve immune function, and enhance well-being. It can help ease the transition for veterans returning home and experiencing reintegration problems, and it might increase marital satisfaction for Warfighters returning home after high combat exposure.
So how do you do it? When you’re feeling stressed or anxious or just struggling to make sense of something, find 15–20 minutes to write. Include your take on the situation at hand. Reflect on how it’s impacting you and what you’re doing to get by. Use writing as a space to say what you can’t say to anyone else. The format doesn’t matter—on a piece of paper, inside a journal, or in a digital document. While writing, you might notice that you’ve developed a different perspective on events. You might identify a silver lining to a difficult experience. You might highlight effective and ineffective ways you’re coping, helping you take further action to seek help or use those strategies in the future. Sometimes it helps to do this over 3 or 4 consecutive days.
And remember: If you’re continually struggling or feeling more distressed even after writing, consider seeking help through a mental health professional or other resource.
Seafood is a good source of protein, healthy fats, and other nutrients that can boost your heart health and performance. It also might reduce your risk of cancer, diabetes, neurological disorders, and even depression.
Aim for two 4-oz servings each week. It can be as easy as opening a can of tuna, sardines, or salmon or thawing a bag of shrimp or fillets. Select fresh when possible, but frozen and canned varieties are often cheaper and more convenient. By varying your choices, you can fit seafood in your budget and find new kinds to enjoy. Remember: If it’s already in your pantry or freezer, chances are you’ll eat it more often!
- Choose from several varieties. These include fish fillets, shellfish (such as crab, shrimp, and lobster), oysters, mussels, and clams. Fatty fish—rich in omega-3s that boost heart health—include salmon, mackerel, lake trout, sardines, and albacore tuna. Select shrimp or a mild-tasting fish such as tilapia or flounder if you’re eating seafood for the first time. In addition, young children and women who are pregnant or nursing should consume fish and shellfish that are lower in mercury.
- Make it lean. Grill, broil, or bake your seafood instead of breading and frying it. Experiment with different spices and herbs too.
- Cook once and eat twice. Use leftovers to top salads, fill tacos, or toss with whole-wheat pasta. Here are a few quick recipes: Add one cup of fresh or frozen corn to your favorite seafood chowder for an easy meal. Or mix one egg, 2½ cups prepared mashed potatoes, 1 Tbsp parsley (chopped), and ½ cup green onions (chopped). Add 14½ oz canned salmon (drained and flaked). Hint: Use a fork to crush the salmon bones for an extra boost of calcium! Mold into 8 patties, dip in bread crumbs or panko, and cook in a nonstick pan until golden.
