Motion sickness - what to do?

From a 2011 BMJ review:

Travel by car, train, or other transport is part of everyday life for most people, and therefore motion sickness is a quite common problem. It was recognized in the early days of sea travel and the word for sickness, “nausea,” derives from the Greek word νανς, meaning “ship.”

Motion sickness is also a potentially disabling problem, thought to be due to sensory conflict or “mismatch” involving the vestibular system.

Symptoms can be provoked by:

- externally imposed motion
- implied self motion from a moving visual field, such as in a cinema

Symptoms

Motion sickness manifests with:

- nausea, vomiting, and stomach awareness
- increased salivation
- belching
- pallor
- sweating
- headache
- dizziness
- apathy, drowsiness, and malaise
- hyperventilation

Habituation

Behavioral treatments such as habituation can be effective but at the same time they can be unpleasant and time consuming

Hyoscine

Hyoscine is an effective preventive medication. There are oral forms and transdermal patches. Hyoscine nasal spray is also effective in preventing motion sickness

Evidence to support the use of other drugs is weaker, especially taking into account the trade off between efficacy and adverse effects. Traditional remedies such as ginger and acupressure bands have not been effective.

Dr. Daniel Montero, a sports-medicine physician within the Department of Orthopedics at Mayo Clinic in Florida discusses what kind of exercises are you should take part in if you suffer from joint pain. Remember, "motion is lotion", says Dr. Montero.

Exercises you may need to avoid if you have moderate or severe osteoarthritis of the knee or hip include:

- Running and jogging. The difference between how much force goes through your joints jogging or running, as opposed to with walking, is sometimes more than 10-fold your whole body weight

- High-impact aerobics

- Any activity where, at any time, you have both feet off the ground at once, however briefly (basketball, jumping)

Fortunately, that leaves a lot of activities that are OK for people with knee and hip osteoarthritis and that can help keep you mobile - see the list at WebMD.
