Hooah 4 Health describes the "7 Emotional Cycles of Deployment" for couples - that both the deployed partner and one at home experience. At first, there is anticipation of departure, then detachment and withdrawal. This can lead to feelings of emotional disorganization. Over time, each partner copes with the deployment so that recovery and stabilization occur. Then, anticipation of the partner's return can start the countdown to deployment’s end. Once back home, partners adjust and renegotiate their roles and can be completely reintegrated and stabilized within a few months. These stages are discussed in detail at the Hooah4Health website.

Sleep requirements vary slightly from person to person, but in general, most healthy adults need at least eight hours of sleep each night to function at their best. Food fuels our way through the day (can give you the necessary energy to pull you through the day), but did you know that food also has an effect on how we sleep? Watch what you eat in the course of a day – particularly in the hours before you go to bed – if you want to optimize your sleep at night. We give you some tips below on the best foods to eat to help you sleep soundly, and those to avoid if you have trouble resting at night.
Foods to avoid before bed:
- Caffeine: Caffeine can cause sleep disturbances even many hours after drinking it. Some people find there’s a cut-off time for their bodies – caffeine before that time won’t affect their sleep, but anything after, say, 2:00 p.m. can cause problems with their sleep. Caffeine is found in coffee, tea, and chocolate, among other foods.
- Alcohol: Some people think of alcohol as a nightcap to help you sleep better. While it may help you get to sleep faster, it also reduces sleep quality by waking you up later, in the middle of the night. A glass of wine before bed should be fine; several stiff drinks are not.
- Big or heavy meals: Fatty food takes time to digest and may keep you from getting to sleep. Spicy and acidic foods at night often cause stomach problems and/or heartburn. Try having an earlier dinner and avoid heavy, rich foods within two hours of when you’ll be going to bed.
- Liquids: Caffeinated drinks act as diuretics, resulting in frequent nighttime trips to the bathroom, and drinking too much water or other liquids close to bedtime also increases your trips to the bathroom in the night.
- Sugar: Anything too sugary, like many desserts or nighttime snacks are, can interfere with your sleep.
Best foods before bed:
- Bananas: Bananas contain large amounts of tryptophan, which triggers the release of melatonin and serotonin in our brains, helping us relax.
- Dairy: Dairy is also a good source of tryptophan, especially combined with some carbohydrates, like oatmeal. A warm glass of milk or a small bowl of oatmeal should help you sleep.
- Turkey: Another good source of tryptophan. Think of the post-Thanksgiving turkey slump many of us experience! Combined with whole-wheat bread in a small sandwich, this is a recipe for a deep, relaxing sleep.
Quality sleep is essential to our health. To start sleeping soundly, try some simple modifications to your diet and see if it helps you.
Did you know that eating right not only helps you stay healthy, but may also help you sleep better? The type of food that you eat has a significant impact on many aspects of health.

It has been known to trainers that alternating higher intensity and lower intensity training sessions is the most effective means for conditioning athletes.
As reported in the September 20, 2010 edition of the Tauton Daily Gazzette (Tauton, MA), recent research indicates that it is not necessary to train at high-effort levels every exercise session. In other words, a combination of higher intensity and lower intensity exercise is recommended for a sensible and successful fitness program. The full article can be accessed here.
