Essential Tips for Your First Day in Cusco to Combat Altitude Sickness

Arriving in Cusco is unforgettable — the history, the mountains, the energy of the Andes. But at 3,400 metres (11,150 ft), your body will notice the altitude immediately.

It’s completely normal to feel more tired than usual, slightly lightheaded, short of breath when walking uphill, or even develop a mild headache. For some travellers, sleep can also feel lighter or more disrupted on the first night.

The good news? Your first 24 hours can make a huge difference in how smoothly you adapt.

Why Altitude Affects You

At higher elevations, the air contains less available oxygen. Your body needs time to adjust by increasing breathing rate, heart rate, and eventually producing more red blood cells. This adaptation process takes time — and pushing too hard too soon can make symptoms worse.

That’s why your arrival day should be focused on supporting your body, not testing it.

What To Do On Your First Day in Cusco

1️⃣ Take It Easy

Avoid intense physical activity,which can be hard as Cusco has plenty of hills. Even if you feel “fine,” your body is still adjusting. Save major tours or hikes for later in your trip if possible.

2️⃣ Stay Hydrated

Altitude can increase fluid loss through faster breathing. Drink water consistently throughout the day. Herbal teas are also a great option.

3️⃣ Eat Light

Stick to lighter meals on your first day. Heavy or overly rich foods can feel more difficult to digest at altitude.

4️⃣ Prioritise Rest

A short nap or quiet afternoon can help your body begin adapting. Give yourself permission to slow down.

Extra Support for Altitude Adaptation

If you want to be proactive — especially before a trek like the Inca Trail, Salkantay, or Ausangate — additional recovery support can make a noticeable difference.

Hyperbaric Chamber Sessions

Our hyperbaric chamber gently increases oxygen availability under light pressure, supporting circulation and helping reduce altitude-related fatigue. It’s a comfortable, relaxing way to give your body an oxygen boost while it adapts.

Gentle Massage Therapy

Travel often means long flights, tight hips, stiff backs, and poor sleep. A gentle massage improves circulation, reduces muscle tension, and supports overall relaxation — helping your nervous system settle at altitude.

The Smart Way to Start Your Trip

Cusco is not a city to rush. The travellers who adapt best are the ones who respect the altitude from day one.

By slowing down, hydrating well, eating light, and supporting your body with recovery therapies if needed, you set yourself up for a stronger, more enjoyable experience in the Andes.
