All the money and wealth of the world cannot buy you good health nor compensate for it. True happiness cannot be fully experienced without good health. Beside the latest medical science's help towards gaining good health, there are ways in Feng Shui and Vaastu to be healthy and fit. Good health that leads to a long and stable life is considered a very special kind of luck. Having prosperity and wealth without health is, in fact, regarded as a state of deprivation like having everything in the world and not being able to enjoy it.
For good health the most powerful energy can be found in the central zone of house or work place. The energy here is associated with good physical, spiritual and emotional health. As per Vaastu this central area is also known as Brahmasthana - the seat of Brahma, who is the god associated with the origin of the universe and a symbol of creation. We should keep this space all clear and sacred. Lord Brahama's spiritual power will radiate outward into the rest of the house, bringing happiness, health and prosperity to each of the occupants.

Suggestions    
Wind chimes at the entrance are an invaluable aid to strengthening your health. Sickness generally enters from the main door, and as per feng shui, the energy of disease belongs to the earth element. Earth gives birth to metal and thus weakens the virulence of the illness, so you will be healthier, and by any chance you fall sick, your recovery will be much faster.
Energizing the east section of your house as this area represents Health and Longevity. Avoid sleeping under the overhead beam as it will cause headache, sleeping facing the mirror or having water plants, aquarium, painting of lake and river is not preferred.
Bamboo plant symbolizes youth because it is evergreen, it never changes. The tree stands upright and proud through every season and the worst storms, always convinced of its power. It is a symbol of trust and permanence.
Red and Yellow Flowers placed in a glass or crystal vase in the health area are a useful and simple cure. Use fresh flowers if possible or keep artificial flowers but not dry flowers. Very effective cure for stomach and the digestive system.
Purchase the fresh ingredients as processed food has stagnant Ch'i, while fresh food offer vitality and life-giving energy. Keeping bowl of fresh fruit can attract positive Ch'i into your kitchen and food.
Balance your meat and vegetables intake, and be sure your meals include fresh vegetables. Meat alone is too yang and can upset your stomach or health problems. Meat represents life taken away, while vegetables offer restoration.
Aromatherapy Burner will have a revitalizing effect on your health if it is used in the centre of your house. It doesn't matter what type of aromatherapy oils you use as long as you like the fragrance.
When you have an exposed overhead beam it is important to move your bed out of the way of poisonous Ch'i being sent directly to it.  This type of beams in the bedroom can create a heavy oppressiveness that can cause, headaches, stress and other problems. Move your office table so that you are not sitting directly under the beam. If beams or exposed ductwork hang directly above your desk, you may feel depressed and uninspired in your work. Also make sure that your visitors are also not seated under the beam.
Spiral Staircase in your home may be quite nice and aesthetically pleasing, it can damage your health, especially if it is in the centre of the house or in the Fame Area. If it is located in either place, spiral staircase can contribute greatly to developing heart, circulatory and coronary disease.
House Facing T-Junction the position is like gun being pointed straight at the house. The impact on the occupants is not healthy and may suffer poor health. It is suggested to reposition the main door.
Centre of the house is the worst location for the toilet in the home or workplace. It is quite common feature in houses where the builder has considerately installed a toilet under the stairs, but from feng shui point of view this is considered a disaster for health and financial prospects.
