With literally billions of people traveling by air every year now, researchers are finally starting to gather and publish more data about the health risks associated with airplane travel. In terms of the common cold, it is now well-accepted that acute respiratory infections are frequently experienced after air travel. Studies have found a high prevalence and wide array of respiratory viruses in people who have recently traveled.[2] Up to 20% of passengers may develop respiratory infections within 1 week after air travel and that flight attendants have significantly more respiratory infections than those who do not frequently fly.

- Spread of exhaled infected droplets. Airline cabins have lots of people in a crowded space who are there for long “exposure times” so the risk of infection via airborne transmission could be high if one or more passengers are infected with an airborne infectious disease. The droplets exhaled by an infected passenger may contain infectious agents such influenza. The droplets have been shown to spread through the air from a single cough, a single breath, or a few seconds of speaking. Exposure to the row in front and the row behind occurs within 30 seconds and extends to 7 rows within minutes.[3]
- Low air pressure and oxygen compromise immune function. The conditions of low air pressure and low oxygen have been shown to impair certain immune system functions for a few days after long flights.[4] To test how typical airplane air pressure and oxygen levels affect the immune system, researchers studied the effects of a simulated 10 hour flight at an average cruising altitude of 8000 feet; and they measured markers of immune system function in 52 healthy volunteers. They looked at blood samples before and on days 1, 4, and 7 after the flight. The researchers observed a number of immune system changes in the immediate days following the simulated flight. For instance, the subjects’ lymphocyte responses were decreased. Lymphocytes include T cells, B cells, and natural killer cells. Lymphocytes are the primary type of white blood cells made by the immune system to combat viruses, bacteria, and other pathogens. These immune changes, they concluded, “may contribute to an increased susceptibility to respiratory infections commonly seen after long-haul flights.”[4]
Venous thrombosis is also a health concern related to air travel
The lower oxygen levels and prolonged sitting on long flights doesn’t just impair your immune system’s ability to fight infections, it also puts you at risk for deep vein thrombosis and pulmonary embolism. Together, these two conditions make up the third most common cardiovascular disease after heart attack and stroke. For persons who contract the conditions, they carry a high risk of death and permanent complications. Deep vein thrombosis is a condition in which a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. Deep vein thrombosis can cause leg pain, but often occurs without any symptoms. Pulmonary embolism is a complication of deep vein thrombosis in which one or more arteries in your lungs becomes blocked by a blood clot that has traveled to your lungs from your leg.
While these conditions are of most concern for people with chronic respiratory diseases, doctors who specialize in travel medicine and lung diseases have been trying to spread the word for years that all travelers need to take precautions to avoid venous thromboembolism. This involves avoiding excess alcohol and caffeine-containing drinks, remaining mobile and exercising during the flight. For air travelers with a history of venous thromboembolism, obesity, heart disease, significant medical illness in previous six weeks, immobility, pregnancy or estrogen therapy (hormone replacement therapy or combined oral contraceptive pill), experts advise that in addition to the above advice, travelers wear compression stockings, avoid sedatives, and avoid sleeping for prolonged periods in abnormal positions. They also recommend a preventive dose of blood thinning medication for those at high risk of clots, such as those who have recently had a stroke, major surgery or trauma.
How to not get sick while flying
To reduce your risk of getting a respiratory infection while on a flight, here are three specific actions you should take:
- Irrigate your nose (or your children’s) with a saline solution – both before and after the flight – by using a dropper or small squirt bottle. Nasal irrigation with a saline solution helps clean out at least some of the allergen, fungal and viral pathogens from the nose and thus can help to reduce the frequency of infections. Keeping the nasal cavity moist in the dry atmosphere of an airplane cabin is also most beneficial.
- Drink lots of water throughout the flight.
- Take an herbal medicine with immune boosting properties such as Echinacea for a week or two before the flight. Australian researchers conducted a randomized, double-blind placebo-controlled trial to study whether a standardized Echinacea supplement is effective in the prevention of respiratory and other symptoms associated with long flights.[5] They gave 175 adults travelling for 15-25 hours Echinacea (root extract, standardized to 4.4 mg alkylamides) or placebo tablets starting 14 days before travel. The Echinacea group had lower respiratory symptom scores compared to placebo during travel. If you’re planning on traveling by air, you can give your own immune system a boost with Echinacea or other immune stimulating natural therapies starting at least 2 weeks before you travel. For more ideas on natural immune boosters for prevention of viral infections, such as Elderberry, Beta-Glucans, and Red Korean or American Ginseng, see the article titled 3 Immune System Supplements to Prevent the Flu this Winter.

When we think about depression, lack of motivation, or difficulty focusing and concentrating, the well-known brain chemical (neurotransmitter) serotonin often comes to mind. While it’s true that low serotonin is a problem for many people with depression and other mental health issues, researchers have known for years that other neurotransmitters are also involved. A study published in JAMA Psychiatry in the year 2000 reported that people with clinical depression also have significantly lower brain levels of the neurotransmitter dopamine.[1]
Since then, we’ve learned a lot about dopamine’s role in mood and mental health and about what can be done to restore low dopamine levels. Loss of pleasure, loss of motivation, and not having enough focus or concentration to get things done can all be dopamine deficiency symptoms, as can the characteristic “slowness” of many people with depression. While most pharmaceutical drugs designed to increase dopamine are associated with significant and serious adverse effects, scientists have discovered and clinically tested a number of natural dopamine boosters that can safely increase dopamine levels within the brain and are generally without side effects. Natural and integrative physicians have been successfully using these ingredients to help patients with depression, anxiety, low motivation, and other symptoms of low dopamine.

What is dopamine?
Dopamine normally gets triggered when you approach and expect a reward. With the release of dopamine in the brain comes a good feeling and a surge of energy so you can reach your reward. Dopamine motivates you to seek, alerts your attention to things that meet your needs, and motivates you to persist in your pursuit of those things that meet your needs. Your brain rewards you with dopamine each time you take steps towards a new goal. Without enough dopamine, your motivation goes caput and you’re unable to experience pleasure from activities usually found enjoyable, e.g. exercise, hobbies, music, sexual activities or social interactions. In other words, dopamine deficiency causes a bad case of the “blahs.”
The four supplements presented here—L-Tyrosine, Rhodiola, Mucuna, and L-theanine—have each been found in studies to increase dopamine and/or help balance dopamine function in the brain. They can be used as natural dopamine boosters to improve mood and motivation and to treat dopamine deficiency symptoms like depression, fatigue, lack of interest in life, poor memory, and impulsive behaviors.
4 Key Dopamine Supplements:
L-Tyrosine. The conditionally essential amino acid tyrosine is a precursor of catecholamine neurotransmitters, including dopamine. It can be taken through the diet (especially from meat, eggs, and fish) or synthesized in the body. Tyrosine forms DOPA, which is then converted to dopamine, and this, in turn, forms norepinephrine, another neurotransmitter related to mood. By supporting production of neurotransmitters like dopamine, L-tyrosine supplements can enhance mood, sleep, emotional well-being, and cognitive/mental function, especially under situations involving environmental and emotional stress or when dopamine levels require additional support (some people are genetically programmed to make too little dopamine).[2-4] Start by taking one 500 mg capsule of L-tyrosine. If you feel no benefits within 30 minutes, take a second capsule, and a third in another thirty minutes if you still feel nothing. Continue by taking one to three 500 mg capsules 2-3 times a day, early morning, midmorning, and midafternoon. Decrease the dose if you feel agitated or your blood pressure increases.
Mucuna. Mucuna pruriens, commonly known as velvet bean, naturally contains up to 5% L-Dopa (levodopa). L-DOPA is the same biochemical that is made in humans from the amino acid L-tyrosine and is then synthesized into dopamine. When taken as a supplement, the L-DOPA from Mucuna can cross the blood-brain barrier to elevate brain dopamine levels. Powdered mucuna seeds have long been used in Indian traditional medicine as support in the treatment of various illnesses, including Parkinson’s. Recently, studies utilizing Mucuna supplements have shown promising results not just for Parkinson’s but for other conditions related to dopamine deficiency, including depression and psychological stress.[5-7] Mucuna extract has been shown to increase not only dopamine concentrations, but also other neurotransmitters that affect mood, such as serotonin and norepinephrine.[8] Look for an extract of Mucuna pruriens standardized to contain 15% L-DOPA. Take 300 mg twice a day.
L-theanine. L-theanine is an amino acid uniquely found in green tea that creates an alert state of relaxation without drowsiness. L-theanine is known to be able to cross the blood-brain barrier and increase dopamine levels in the brain. Animal studies show that L-theanine also increases brain serotonin and GABA. It has anti-depressant and anti-anxiety effects, reduces mental and physical stress, and leads to improvements in learning and memory in humans and animals.[9,10] Even just a single, small dose of L-theanine (100 mg) significantly improves the ability to pay attention and maintain focus compared to placebo.[11] Take 200 mg of L-theanine 2-3 times daily.
Rhodiola. Rhodiola rosea, or ‘golden root’, is a popular plant in traditional medicine in Eastern Europe and Asia, with a reputation for improving depression, enhancing work performance, eliminating fatigue and treating symptoms resulting from intense physical and psychological stress. Rhodiola exerts its benefits via multiple effects on the central nervous system, including enhancing the stability of dopamine and supporting its reuptake. This leads to notable decreases in depression, anxiety, and fatigue, as well as an increased ability to handle stress.[12] In human studies, rhodiola has been shown to significantly reduce depression, anxiety, and stress-related fatigue compared to placebo.[13-15] Look for a rhodiola extract derived from Rhodiola rosea root and standardized to contain 3% total rosavins and a minimum 1% salidrosides. Take 170 mg twice a day.
Multivitamin. Certain minerals and B-vitamins, especially zinc, vitamin B6, and folate, are necessary for dopamine synthesis and neurotransmission. These nutrients are often depleted in individuals due to medications, inadequate diets, excessive stress, and toxic environmental exposures, compromising the ability to properly synthesize neurotransmitters like dopamine. A high-potency, high-quality multivitamin/mineral supplement can help replenish these co-factors, enhancing neurotransmitter function and playing a complementary role in supporting emotional wellness
Potential side effects, precautions, and drug interactions
Too much dopamine is dangerous and needs to be avoided. Do not take more than one dopamine supplement at a time without first consulting with a healthcare practitioner, preferable one trained in integrative or natural medicine. Similarly, do not use these supplements if you are taking methyldopa, antidepressants, or antipsychotic drugs without first consulting with a physician. Tyrosine and Mucuna pruriens may also interact with some nutritional supplements, including St. John’s Wort, 5-HTP, Tryptophan, and SAMe. Therefore, you should also consult your healthcare practitioner before combining these supplements. Do not take these supplements if you are a pregnant or lactating woman.
Additional ways to increase dopamine and improve your mood
In addition to taking dopamine supplements, there are also other ways to naturally increase dopamine. For instance, do you know which foods are natural dopamine boosters and which foods can deplete dopamine? Working towards a goal can also increase dopamine. By repeating small steps to reach a goal, you can re-wire the dopamine pathways in your brain, ultimately teaching your brain to give you a dopamine surge every time you take that small step. You can also increase dopamine by developing an active, regular, stress reduction practice.[16]
