What causes sudden (but prolonged) nausea when walking out the door (as in when moving from air conditioning into heat)?

- Those with lyme can be much more affected by even slight increases in heat and humidity. Do whatever it takes to stay cool - but don't shock your system.
Your symptoms Sound like heat exhaustion. Prolonged nausea after overheating is a very serious warning sign of heat stroke.
You should call your Primary Care Physician for advice - or call your Urgent Care center. Best to stay home if you can and get advice over the phone. It's just too hot out there lately, in most states.
Many things can affect this but we have to be more careful. It's really quite typical for anyone with health challenges. The inner ear has to adjust and anytime the inner ear is taken for ride, nausea occurs.
Vasovagal responses are all stressed. Dehydration makes that worse.
There can also be changes in cardiac function, in sympathetic and autonomic nervous system functions - which gets all messed up with lyme, anyway, but when heat and cold shifts are added in, all bets are off.
Are you getting enough water? Electrolytes? Getting enough sea salt? Eating enough?
It's very, very hot these days. The change in temp may be too sudden for your body. But, really, heat can be horrible for lyme patients. Try to avoid it as best you can.
If you can transition from house to garage before going out, that is best. Keep your car in the shade if you can, and use a windshield shied when you have to park in sun.
Open all the doors and wait a minute before getting into a hot car. If you can have ice pack with you, that is best. One for the small of our back, one to drape around neck, being sure it covers sides of your neck.
You can take a kitchen towel, moisten it and roll into a, well, a roll. Put in freezer and unroll to drape on your neck as you leave the house. Do not saturate it or it will just freeze as a block of ice. Put in a plastic bag. Keep several on hand in the freezer at all times. And, if you work, do this at work for your return ride home.
Be sure the AC is not too cold. Avoid cold drinks, actually. Cool, chilled are okay but ice cold drinks can shock your body.
If you have to walk in the sun at all, use a sun umbrella. Really.
Heat exhaustion is a warning sign to heat stroke. Both are very serious, indeed. Be careful. -

- Your food plan may be splendid. This article recently caught my attention, so, just in case you've eaten some processed foods lately, this could be part of an explanation (McNuggets are not the only fake foods with such additives and effects): ---------------------------
`` . . . One gram (one-thirtieth of an ounce) can cause "nausea, vomiting, ringing in the ears, delirium, a sense of suffocation, and collapse," . . . .
CNN's ``The Chart'' David, David Martin - CNN Medical Senior Producer
June 25th, 2010
Excerpts:
All McDonald's nuggets are not created equal. U.S. McNuggets not only contain more calories and fat than their British counterparts, but also chemicals not found across the Atlantic. . . .
. . . American McNuggets (190 calories, 12 grams of fat, 2 grams of saturated fat for 4 pieces) contain the chemical preservative tBHQ, tertiary butylhydroquinone, a petroleum-based product. They also contain dimethylpolysiloxane, ``an anti-foaming agent'' also used in Silly Putty.
By contrast, British McNuggets (170 calories, 9 grams of fat, 1 gram of saturated fat for 4 pieces) lists neither chemical among its ingredients. . . .
** . . .TBHQ is a preservative for vegetable oils and animal fats, limited to .02 percent of the oil in the nugget. One gram (one-thirtieth of an ounce) can cause "nausea, vomiting, ringing in the ears, delirium, a sense of suffocation, and collapse," according to ``A Consumer's Dictionary of Food Additives.'' . . . **
. . . Dimethylpolysiloxane is used as a matter of safety to keep the oil from foaming, McComb says. The chemical is a form of silicone also used in cosmetics and Silly Putty. . . .
. . . ``The regulations in Europe, in general, around food are much stricter than the U.S.,'' Kimball says. . . . -

Hyperthermia is an elevated body temperature due to failed thermoregulation.
Hyperthermia occurs when the body produces or absorbs more heat than it can dissipate.
When the elevated body temperatures are sufficiently high, hyperthermia is a medical emergency and requires immediate treatment to prevent disability and death.
The most common causes are heat stroke and adverse reactions to drugs. Heat stroke is an acute condition of hyperthermia that is caused by prolonged exposure to excessive heat and/or humidity.
The heat-regulating mechanisms of the body eventually become overwhelmed and unable to effectively deal with the heat, causing the body temperature to climb uncontrollably.
Hyperthermia is a relatively rare side effect of many drugs, particularly those that affect the central nervous system. . . .
. . .
Heat stroke
Heat stroke is due to an environmental exposure to heat, resulting in an abnormally high body temperature.[8] In severe cases, temperatures can exceed 40 �C (104 �F).[9]
Heat stroke may be exertional or non-exertional, depending on whether the person has been exercising in the heat.
Significant physical exertion on a very hot day can generate heat beyond a healthy body's ability to cool itself, because the heat and humidity of the environment reduces the efficiency of the body's normal cooling mechanisms.[8]
Other factors, such as drinking too little water, can exacerbate the condition. Non-exertional heat stroke is typically precipitated by medications that reduce vasodilation, sweating, and other heat-loss mechanisms, such as anticholingeric drugs, antihistamines, and diuretics.[8]
In this situation, the body's tolerance for the excessive environmental temperatures can be too limited to cope with the heat, even while resting.
. . .
Drugs
Some drugs cause excessive internal heat production, even in normal temperature environments.[8] The rate of drug-induced hyperthermia is higher where use of these drugs is higher.[8]
Many psychotropic medications, such as selective serotonin reuptake inhibitors (SSRIs), monoamine oxidase inhibitors (MAOIs), and tricyclic antidepressants, can cause hyperthermia.[8]
Serotonin syndrome often presents following exposure to multiple drugs. . . .
Many illicit drugs, including amphetamines,[11] cocaine,[12] PCP, LSD, and MDMA can produce hyperthermia as an adverse effect.[8]

===================
Regarding certain meds that can raise internal temperature, I would avoid hot herbs on hot days - such as Garlic/Allicin and Oregano Oil capsules, especially - if they seem strong to you.
While eating some hot spices do actually help some to manage heat, lyme patients' inner control with temperature is often damaged so all bets are off.
Olive Leaf Extract is a cold herb that works best for me on hot days. -

- MUCH better than a hat, Personal Sun Umbrellas. I would store it in the fridge, actually, so that it has a bit of a coolness to it for at least a minute. At least keep it indoors when not in use so it does not get too hot.
I can imagine ways to add a misting effects but you can also get a spray bottle and take with you. ----------------------------
