Instructions on Health Care

What are the differences between the cabin environment and daily life?

Cabin temperature

Cabin humidity

Cabin air pressure

Cosmic radiation

Generally speaking, the cosmic radiation that we suffer on long distance flights is about 0.004 ~ 0.005mSv, and in short distance flights is 0.001 ~ 0.003mSv. The radiation of X ray one time is about 0.02 ~ 0.04mSv. Therefore, we can be sure that the cosmic radiation that we suffer during our flight is safe, and has little impact on human health.


Cabin noise level

Information about peanut allergies

It is difficult for us to forbid passengers to take peanut products, open peanut packages or eat peanuts in the cabin. In addition, residual peanut components in past flights may still stay in the cabin.


Can I use deaf-aid or cardiac pacemaker on the plane?



How to reflex myself on the plane?

A relaxation exercise against the travel stress

Position yourself comfortably in your seat, lay your hands loosely on your belly and breathe in slowly and deeply through your nose. When breathing out again through mouth and nose watch how your belly bulges out noticeably.. With this conscious breathing technique you will do your body a lot of good by providing yourself with an extra portion of oxygen and new energy.


A trick to relax your eyes:

Sit comfortably, rub your hands together to heat your palms, and then place them over your closed eyes to shut out all light. Now take a deep breath and think of a pleasant scene – after three minutes you will have gathered fresh strength.


A Special treat for your face:

With your fingertips, put light pressure on your forehead whilst tapping your skin softly. Work them slowly over the rest of your face and enjoy the relaxing effect.


How can I sleep better on the plane?

Relief for the neck:

Take a cushion for your neck on board with you. This prevents shoulder and neck pain!


Relief for the back:

Simply place a cushion behind your back. This relieves the pressure on your spinal discs and prevents backache!


Comforting warmth:

Before sleeping, you can ask a flight attendant to give you a blanket before you go to sleep so that the air-conditioning won’t make you feel cold and disturb your pleasant dreams.


Rest your eyes:

A sleeping mask (available at chemists) protects your eyes from bright light.


What should I pay attention to before the flight and during the flight?


Refreshments before the departure of the airport:

Before takeoff, it is beneficial for you to eat some refreshments and drink a beverage.


Drink a large quantity of water during the flight:

Since the cabin humidity is quite low, your body needs more water than on the ground. When humidity is declining, the air becomes dry. In long-distance flight, your skin will feel uncomfortable due to the dryness of mucosa. The general principle is that you should “eat less but drink more” during the flight. When you are on the plane, your digestion will become “weak”. So it is better for you to eat some low-fat foods, such as fruits and vegetables. In addition, you should drink a cup of non-carbonated mineral water or juice every hour.


Our suggestions:

We suggest that you should not drink coffee, black team, cola, and alcoholic beverages since the liquid quantity brought to your body by the beverages is not enough to supplement the quantity taken away by them.


Special tips for children

Children, in particular, should take much more liquid. Compared with their weight, their body surface is relatively larger. This means that they evaporate much more moisture through skin than adults.


What else should I remember during the flight?

Travel sickness

Jet lag

Poor blood circulation (Economy-Cabin Syndrome)

What shall I do if I am sick onboard?

If you are sick during the flight, CSN will actively adopt measures to ensure your health. If your sickness is serious, CSN will do its best to offer treatment.


What is jet lag?

So-called “jet lag”, medically referred to as desynchronosis due to the change of geographical position, is a temporary physiological disorder condition resulting from alterations to the body's circadian rhythms during rapid long-distance travel on an aircraft over several time zones.


What are the impacts of jet lag?

Jet lag may cause troubles such as insomnia, digestive discomfort, headaches, low spirits, poor concentration and poor performance etc. This is much more serious when passengers fly from west to east (for instance, from Taiwan to America via Pacific Ocean) than when flying from east to west.


How to adjust for jet lag quickly?

The three basic methods for the rapid adjustment of jet lag are: adequate sleep before the flight and healthy food as well as taking exercise, absorption of water during the flight, and compulsory rest and work time according to the local time.
