5. Venous Thrombosis:
Some of the travelers who go a long distance are prone to develop blood clots in their calf veins, which is known as deep venous thrombosis (DVT). This DVT is manifested as swelling, redness and dull pain on compression in calf. This clot from the legs can travel upto the lungs causing Pulmonary embolism (PE). This PE manifests itself in the form of chest pain, cough, breathlessness, rapid shallow breathing and aggravation in chest pain on deep breathing.
PE is a medical emergency and should be addressed immediately with Oxygen therapy and thrombolysis.
People who are risk of developing these clotting problems include those with previous history of spontaneous clot formation anywhere in the body, those who have been sedentary, such as bed or chair bound, for long times, elderly, those with hypercoagulation disorders, those using estrogen-based contraceptives, recent surgery, recent injury, obesity and active cancer.
These problems can be prevented by wearing properly fitting compression stockings to assist in blood flow in distal legs, remaining active while traveling such as getting up and taking a walk every now and then. Keep pumping your calf muscles by contracting and releasing them. Also keep raising your heels while keeping toes on the floor and vice versa.
If you are a high risk person then consult your doctor before travel, he may want to start a prophylactic medicine.
The only reason that people travel for is enjoyment. We strongly recommend that you enjoy with responsibility and don’t be ruthless to yourself. People get intoxicated with alcohol and all sorts of other things including weed etc. Not only they intoxicate themselves but they fall prey to fraudsters who intoxicate them and deprive them of their belongings and at times bodily harm has also been inflicted so much so that some of the tourists have been raped and murdered. So just be careful with alcohol, drugs and by fraudsters.
7. Extreme weather effects and Exertion:
When you are travelling from one hemisphere to other or from poles towards equator and vice versa, you must check before starting off and make necessary arrangements in the form of appropriate clothing, raincoat, umbrella etc. Also arrange for required cosmetics such as sunbolcks, moisturizers etc.
Once you have arrived at your destination let your body acclimatize to the local conditions by gradually increasing the severity of your physical exertion instead of embarking onto adventure straightaway.
Keep yourself well-hydrated and calorified lest you may dehydrate or drain yourself of energy.
8. Irregular dietary intake:
Most of us are not regular in our meals during our routine lives. Travelling exposes to irregular eating all the more. It is strongly recommended that meals containing balanced diet and valuable nutrition must be consumed at regular intervals for not only to keep your energy levels at optimum level but also to prevent you from contracting the diseases to which you become excessively prone if you are and taking enough calories both in terms of quality and quantity.
To enjoy your trip take at least three main meals, which should include at least 100 grams protein a day, rest of the meals can be mainly constituted of different types of carbohydrates.
9. Sleep disturbances:
Jet lag can mess up your sleep routine. Hence when you planned a trip try to bring your sleep cycle in sync with your destination time zone. Once you have boarded the plane reset your watch to destination time zone. Once you have reached your desired place strictly practice sleep hygiene, which includes taking meals at times, remaining well hydrated, avoiding caffeinated drinks such as coffee and tea after midday, make it a peaceful sleeping experience by avoiding all the city noise and flashing lights. For this purpose you can even use earplugs and eye-shades.
Melatonin tablets can help fix your sleep cycle in a new timezone. But you must consult your doctors before deciding to use these although melatonin use has been declared safe even in children by numerous studies.
10. Mind Boggling:
When you are traveling to and from one timezone to the other and from one type of weather to the other and from one terrain to the other, it takes its toll both on your body and mind.
Your mind may remain blurred for some days after finishing your travel. It may adversely affect your concentration, attention and memory, however these recover to their fullest in few days.
