Health, Safety & Survival

The actual risk picture, corrupt police, earthquakes, water, air quality, healthcare costs, insurance, and how to not be the person who finds out the hard way.

CDMX is not the most dangerous city in Mexico, not even close. It is also not as safe as the median European or North American city. The honest picture sits somewhere between the paranoid headlines and the breezy dismissal of anyone who’s been here three weeks and decided the fear was all media invention. This chapter covers both the real risks and the genuine non-risks, and what to actually do about the former.

The Real Safety Picture

The central neighbourhoods where most expats live — Roma Norte, Roma Sur, Condesa, Juarez, Polanco, Narvarte, Escandon — are not dangerous in the way the word is commonly used. Walking during the day, going to restaurants and bars at night, using Uber, going to the market: these are normal activities and the vast majority of people do them without incident for years.

The risks that actually exist in these neighbourhoods:

• Phone theft. The most common crime affecting expats. Phones are snatched from hands, from tables in restaurants and cafes, and from pockets in crowded spaces. Keep your phone in your front pocket or bag when not actively using it. Do not use your phone while walking. At outdoor cafe tables, keep it off the table or in your lap. This is not alarmism — it is the most consistent piece of advice from everyone who has lived here for more than six months.
• Pickpocketing on the metro. Particularly during rush hour crush on busy lines. Keep your phone in a front pocket. Hold bags in front of you. This is manageable and should not stop you using the metro.
• Bag snatching. Bags and backpacks worn casually on the street are occasionally grabbed, particularly at night. A bag worn in front or a bag kept close to your body is lower risk than one hanging loose behind you.
• Opportunistic theft from restaurants. Someone walking through a restaurant and lifting a laptop or bag from an unattended chair. It happens. Keep bags on your lap or your foot through the strap. This is not unique to CDMX but the practice is common enough to be worth knowing.

“My friend was going into a supermarket and her phone was snatched from her hand at the entrance. It happened in under a second. She didn’t even see who did it.” — resident on how quickly it happens

“I left my wallet and phone at a cafe near my place and someone sent me a Facebook DM about it. I couldn’t believe I was dumb enough to do that and that someone was kind enough to return them. In LA both are gone in 60 seconds.” — resident noting the contrast

What is not a realistic risk in the central neighbourhoods: cartel violence directed at foreigners, targeted kidnapping, violent robbery at gunpoint in Roma or Condesa during normal hours. These things are real in other parts of Mexico and in other parts of CDMX. They are not the daily reality of the neighbourhoods this guide covers.

The Police Situation

The CDMX police force is not corrupt in a uniform way — but corrupt officers exist and they specifically target foreigners, particularly foreigners who are alone, at night, and visibly carrying things.

The most common scenario: a police officer stops you and claims you have done something illegal (drinking in public, behaviour that seems suspicious, being near something that happened). The goal is a ‘mordida’ — a cash bribe to make the situation go away. The amount is typically 500–2,000 MXN.

How to handle a police stop:

• Stay calm. Do not become aggressive or make accusations. This escalates things.
• Ask to see their credentials (credencial). A legitimate officer will show them. A scammer playing dress-up may not have them.
• If they claim you’ve done something, ask to be taken to the nearest police station to resolve it formally. This often ends the interaction immediately — corrupt officers who want cash do not want to go to a police station.
• The MiPolicía app has an emergency button that connects you to English-speaking tourist police. Download it before you need it. The number alone acts as a deterrent: telling an officer you are calling the tourist police tends to change the dynamic.
• Do not pay a bribe if you can avoid it. It funds the behaviour and makes you a target again. That said: if you are alone, it’s late, and the officers are becoming threatening, paying and leaving is a legitimate choice.

“I have lived in Mexico for 10 years and never paid a bribe. I moved to Mexico City in August 2023. In 10 months I have had to bribe them four times. I am female and always alone when they stop me. They are ruthless.” — long-term Mexico resident on the CDMX-specific problem

“Once I was stopped and just yelled out that I was calling the embassy. They got scared and told me to have a good night.” — resident on a bluff that worked

“Do not drink in public. It is not legal in Mexico City. You may have been lucky before but corrupt police, when they catch you, will not leave you alone until they take you to the police station or you pay. Especially if you’re a foreigner.” — long-term resident warning the newcomers

Earthquakes

Mexico City sits in a seismically active region and earthquakes are a fact of life here. The city experiences multiple detectable tremors per year; significant earthquakes occur less frequently but do occur. The 1985 earthquake killed thousands and reshaped the city’s building codes and emergency culture. The 2017 earthquake killed over 300 people and damaged hundreds of buildings. Both are within living memory for most long-term residents.

The SASMEX earthquake early-warning system sends alerts via loudspeakers throughout the city and via the SASMEX app. The alert sounds before the shaking reaches the city from the epicentre, giving anywhere from a few seconds to a minute of warning depending on the earthquake’s distance. The sound is unmistakable: a loud alarm tone, followed by a female voice counting down or announcing the alert.

What to do when the alarm sounds:

• Move away from windows and heavy furniture. Do not stand in a doorframe — this is outdated advice from old construction methods. Get under a sturdy table or desk if you’re indoors, or move to an open area away from buildings if you’re outside.
• If your building has a designated meeting point (punto de encuentro) for earthquakes, know where it is before you need it. Ask your portero.
• If you’re on an upper floor of a modern building, the building may sway significantly but not necessarily be in danger. Newer buildings in CDMX are designed to flex during earthquakes. That said: get out if you can do so safely before the shaking starts.
• September is earthquake month culturally — earthquakes in 1985 and 2017 both struck in September. The city-wide earthquake drill happens annually on September 19th at 11am. If you’re here for it, participate. It’s useful to know the sound of the alarm and the city’s response before a real event.

“It’s good to be prepared. Have an earthquake bag ready. Check your building, learn the protocol for exiting in case one hits.” — long-term resident on basic preparation

“This group is my true earthquake alert system. Everyone starts messaging at the same time.” — resident, accurately describing how it works in practice

“Be careful in September. It’s earthquake month.” — resident who has been here long enough to say this without irony

An earthquake bag: a small bag kept near your door with water, a flashlight, basic first aid supplies, copies of your important documents, some cash, and your medications. Takes 20 minutes to put together. Most people don’t have one until after their first significant tremor. Be the person who has one before.

Water

Do not drink the tap water. This is non-negotiable and not paranoia. The tap water in CDMX is not treated to a standard that makes it safe for drinking without further filtration, and the pipes in older buildings add contaminants regardless of what leaves the treatment plant.

The garrafón system: 20-litre water jugs (garrafones) delivered to your door or available at OXXO, 7-Eleven, and most supermarkets. Cost: 25–40 MXN to refill at a water delivery point, 50–80 MXN to buy a new one. A garrafón per week is sufficient for drinking and cooking for one person. Most apartments have a garrafón stand and dispenser.

The empty garrafón question: you can return empties to OXXO for a small credit or exchange at the original purchase point. You cannot always reclaim cash — it’s usually a credit against the next purchase.

Brushing your teeth with tap water is generally fine for most people after an adjustment period. Cooking with tap water (boiling pasta, washing vegetables) is generally accepted as low-risk. The key avoidance is drinking straight tap water or using it unboiled in things that will not be cooked further.

Ice in restaurants: reputable restaurants and bars in Roma and Condesa use purified ice. At very cheap street stands you may want to ask or avoid. At any sit-down restaurant in the central colonias, ice is fine.

Air Quality

CDMX has an air quality problem. It sits in a high-altitude basin surrounded by mountains that trap pollutants during certain weather conditions. Vehicle emissions, industrial activity, and seasonal dust all contribute. The IQAir and WAQI apps give real-time air quality index readings — download one.

Contingencia Ambiental: when air quality reaches critical levels, the city declares an environmental contingency. During a contingencia, additional vehicle restrictions (beyond Hoy No Circula) apply, and in severe cases, outdoor exercise is officially discouraged. These typically occur during dry season — roughly December through May — when the mountain-trapped smog is most concentrated.

Who feels it: people with respiratory conditions (asthma, COPD), people who exercise outdoors regularly, and people who have recently arrived and haven’t built tolerance. Long-term residents often report that their bodies adjust over six to twelve months. People arriving from low-altitude, clean-air environments tend to feel it most acutely in the first weeks.

“You can tell people are returning to work. Traffic is back, and so is the smog from cars. My allergies are here now. The magic of December is over.” — resident on the seasonal pattern

Practical steps: an air purifier in your bedroom makes a meaningful difference for sleep quality and morning respiratory symptoms. HEPA filters. Not optional if you have any respiratory sensitivity. A good one costs 1,500–3,000 MXN and is worth every peso.

Altitude

Mexico City sits at 2,240 metres (7,349 feet) above sea level. That is higher than Denver, Colorado. The altitude affects newcomers in specific, predictable ways: shortness of breath on exertion, headaches, disrupted sleep, reduced alcohol tolerance, and mild dehydration effects that feel like fatigue.

Most people adjust within one to two weeks. The adjustment is faster if you hydrate aggressively, avoid alcohol in the first few days, and don’t immediately start intense exercise. The adjustment is slower if you arrive dehydrated from a long flight and immediately go to dinner and drink mezcal all night, which is what most people actually do.

Altitude sickness (soroche) is rare at CDMX’s elevation but not unknown, particularly in people arriving from sea-level cities. Symptoms: persistent headache, nausea, dizziness, shortness of breath at rest. If symptoms are severe or persist beyond 48 hours, seek medical attention. An IV drip at a clinic provides rapid relief.

“She has been suffering from altitude sickness for two days. She stopped vomiting but has shortness of breath. She had an IV on Friday and felt much better but finds it hard to drink water or stand up. Can anyone connect us with a doctor who can bring oxygen or an IV to the hotel?” — group message about a real situation

Alcohol at altitude: your tolerance is approximately 20–30% lower than at sea level. This is not a suggestion to drink less (though that’s also fine) — it’s information so you don’t feel confused when three drinks hit like five.

Healthcare — The Practical Guide

For basic non-emergency care

Farmacia San Pablo and Farmacia Similares both operate walk-in doctor’s clinics attached to pharmacies. Cost: 50–60 MXN for the consultation. The doctor can write prescriptions, diagnose common conditions, and refer you onward if needed. For a stomach bug, respiratory infection, skin issue, or anything that needs a diagnosis and a prescription quickly, this is the fastest and cheapest option. The quality varies by individual doctor but the format is efficient.

Salud Digna is a subsidised diagnostic lab chain with multiple locations in CDMX. Blood tests, urinalysis, imaging — at a fraction of private hospital prices. The exact same blood panel that one private hospital quoted at 9,225 MXN cost 2,215 MXN at Salud Digna. You do not need a referral for most tests. You do not need an appointment for many of them. Results come same-day or next-day online.

“I went to Salud Digna for the exact same tests a private lab wanted 9,225 pesos for. I paid 2,215 pesos and was in and out in under an hour on a Saturday morning without an appointment.” — resident who learned this the expensive way

For more serious care

The private hospital system in CDMX is genuinely good. Hospital ABC (in Observatorio and Santa Fe), Hospital Ángeles (multiple locations including Polanco and Pedregal), and Médica Sur are the major private networks with international standards, English-speaking staff in many departments, and modern equipment. These are where you go for surgery, serious diagnoses, specialist consultations, and emergencies when quality of care matters most.

Cost without insurance: a specialist consultation at a private hospital is 800–1,500 MXN. Emergency room admission starts at a few thousand pesos and escalates quickly with tests, imaging, and procedures. An appendectomy or similar surgery at Hospital ABC will cost 50,000–150,000 MXN without insurance. This is not American prices but it is also not trivial.

The public IMSS system: available to people with Mexican residency who register and pay contributions. IMSS quality varies by facility but can be adequate for many conditions. Wait times are longer than private. Not typically used by expats for primary care but worth knowing if you are a long-term resident with residency status.

Health insurance options

SafetyWing is the most commonly mentioned nomad insurance in the community. Monthly subscription model, covers emergency medical worldwide, relatively affordable. Deductible is USD 250. It covers emergencies and acute illness but has limitations on pre-existing conditions and elective procedures. Multiple community members have had mixed experiences with claims — read the policy carefully before assuming it will cover a specific situation.

Atlas and similar nomad-focused insurers are alternatives that some residents prefer for more comprehensive coverage. More expensive, broader coverage.

Local Mexican health insurance (GNP Seguros, AXA, Metlife México) for permanent or long-term residents: more comprehensive than nomad insurance, requires residency, lower premiums than international expat plans for comparable coverage. Worth exploring if you have or are planning to get temporal or permanent residency.

A practical note: many medications that require a prescription in the US or Europe are available over the counter at Mexican pharmacies. Antibiotics, sleep aids, anxiety medication, stimulants — the availability is significantly more permissive. This cuts both ways: useful when you know what you need, potentially risky if you self-prescribe incorrectly. If you’re managing a chronic condition, bring enough medication for at least 90 days while you sort out the local equivalent.

“I’m looking for a general doctor, ideally virtual, to get local prescriptions. I assumed Mexico would be like Colombia in being able to buy almost anything over the counter, but it seems there are rules here.” — newcomer discovering the nuance

“Fluvoxamine is available without a prescription here. Just go to a pharmacy and ask.” — resident on one specific example of the permissive system

Dentistry

Dental care in CDMX is excellent and cheap by North American and European standards. A cleaning is 300–600 MXN. A crown is 2,000–5,000 MXN. The community regularly recommends dentists and the overall consensus is that the quality at mid-range private clinics in Roma and Condesa is high. Find one via community recommendation rather than walking in randomly.

“Everyone loves a good dentist here. And bonus, there’s a cheap dentist on the first floor of my building.” — resident on the density of dental options

Emergency Numbers and Apps

911 works in Mexico. Call it for genuine emergencies — medical, police, fire. For non-emergency police matters, there is a separate non-urgent line. LOCATEL (5658-1111) is the city’s information and non-emergency assistance line, in Spanish.

The MiPolicía app (covered above) for police situations. The SASMEX app for earthquake alerts. IQAir or WAQI for air quality. Uber for transport in any situation where you need to get somewhere quickly and safely. These four cover most practical emergencies.

| ⚠️ Keep these saved before you need them 911 (emergency). LOCATEL: 55 5658-1111 (non-emergency city services). Your nearest private hospital address and phone number. Your embassy’s emergency line. A trusted local contact who speaks Spanish well. Your insurance policy number and emergency claims line. None of this is interesting to organise. All of it matters at 2am. | | --- |

General Survival Practices

• Keep 500–1,000 MXN cash on you. Not for bribes specifically — for taxis, tips, street food, and situations where card fails. Cash is not optional in CDMX.
• Do not use your phone while walking. Especially not at night. Especially not near intersections or in crowded areas. The theft is fast and the perpetrators are not running after you.
• Share your Uber trip when travelling at night. It takes 10 seconds. The habit matters.
• Know your building’s earthquake exit and meeting point before you need them.
• Have your portero’s number saved. For everything from locked out to suspicious activity outside your door.
• The areas immediately around and inside metro stations, particularly at night, have higher pickpocket risk. Be especially alert at the transition between street and platform.
• Zona Rosa, particularly certain streets near and around the nightlife area, has a higher incidence of spiked drinks and express ATM situations. Go with people you know and keep your drink in your hand.
• The outer colonias — Tepito, Doctores, Iztapalapa — have different risk profiles than Roma and Condesa. The advice above applies to the central expat geography. If you venture further, research the specific area first.
