Previously, people who could afford it left to rest in the south for at least 21 days. There is a simple explanation for this. If a person is in another geographical zone less, he does not have time to acclimatize and his immunity decreases. If a person spends less than 21 days on vacation and returns healthy, he will most likely become ill after returning. To fly to Thailand for a weekend in February is not a good idea: a person is guaranteed to rest not for three days, but at least a week to recover.
Often, during travels, various unpleasant symptoms may appear: weakness, headache, fever, fluctuation in blood pressure. This is due to the process of acclimatization or adaptation. Acclimatization is an addiction and adjustment of the body to changing environmental conditions. Moreover, the sharper the transition, the higher the likelihood of various symptoms and malfunctions in the body.
If we are talking about an absolutely healthy person, then the manifestations of acclimatization will be minimal – a slight increase in heart rate, fluctuation in blood pressure, weakness, headache. All these are mild symptoms. If this applies to a person who has health problems – diseases of the cardiovascular system, gastrointestinal tract – then all manifestations of adaptation can be expressed more strongly. Therefore, before choosing a place to relax, evaluate the state of your health.
When changing living conditions and time zones for women, a menstrual cycle may fail, hormonal changes. Usually after some time this passes and the cycle is restored.
Changing the climate zone, try to gradually increase the time spent in the sun. In the early days especially. This way you will minimize the chance of getting sick.
What to do in order not to get sick on vacation
Before the trip, it is advisable to consult with your doctor. Good nutrition, moderate physical activity and hardening (without fanaticism) will also help reduce unpleasant symptoms.
Eat only in restaurants recommended by the travel company. Avoid random diners and street food from the trays. In no case should you eat raw fish or seafood – there is a high probability of poisoning. Before eating, be sure to wash fruits and vegetables with boiled or bottled water – that is, not from the tap (if you are in hot tropical countries). You also need to drink only water bought in closed bottles.
If you are in a country where there are blood-sucking insects – mosquitoes, horseflies, midges – remember that they can be carriers of various diseases. In the evening, wear long-sleeved clothing, trousers, boots – especially in countries where there is a danger of getting malaria. Before traveling, evaluate the risks that may arise. If necessary, get vaccinations that your doctor will recommend.
In order to more easily tolerate acclimatization, immunity must be maintained. Standard recommendations are suitable here – good nutrition, compliance with the regime of work and rest, good sleep, moderate physical activity and contrast shower. Please note that we are not talking about taking any special drugs to increase immunity. In principle, it’s not worth taking anything for nothing, without a doctor’s prescription.
