Please think back to the past you were ill.
Most people had to take time off a regular work, right?
Consequently, you were feeling ill on holiday (such as stress out while relaxing outside your workplace).
There are a number of symptoms; for instance, headaches, muscle pain, fatigue, colds and flus.
To simply manage 'Leisure Sickness' you may attempt to learn how a work-friendly environment through having a nice interpersonal skills happens in between two situations: travelling out Vs working in.
In my opinion, relaxation with positive thinking initiates calming your mind, don't u think?
Hoping Thai people won't get much on this kind of sickness na krab.
Thank you krab khun Jaruntorn.
Being stressed through not only job types but also working environments (e.g. physical and social environment) are major causes. Exercising mind and adjusting the major causes should be the best way krab.
