What Temperature Is Dangerous To Sleep Outside?

3 min read

Is it ok for you to sleep outdoors when the temperature is 95℉? What will happen to me if I sleep outside when it’s too hot?

It’s about being acclimatized. If you live in a cold climate, then anything above 82℉ is going to feel like you are in an oven, so sleeping outside at 95℉ could be considered dangerous. If you sleep outside when it’s too hot, you will suffer from dehydration which can result in cramps. You may experience heat exhaustion and start to feel unwell.

What temp is too cold to sleep outside?

It depends on your equipment. If you are an amateur, then sleeping in temperatures of 30 to 40℉ is a ludicrous thought and could be considered outright dangerous.

The key to camping in the cold is having the right gear, including the correct rated sleeping bag and a thermal mat to prevent heat loss.

As a rule of thumb, if you have a sleeping bag rated to 30℉, you will need to add 15℉ to the rating to get a reasonable night’s sleep in the great outdoors.

How warm should it be to sleep outside?

It depends on you and how much experience you have. Sleeping outside when it’s cold can be a great experience if you have the right equipment.

If you carry a few extra pounds, you will likely sleep hot, and a suitably rated sleeping bag and thermal mat will suffice.

Using budget gear is not recommended under any circumstances if you are sleeping under canvas.

Can you sleep in a cold car?

Yes. You will still need appropriate sleeping gear if you want to be comfortable, but if you only have budget gear, you should be ok sleeping in a car.

Get comfortable on the back seat or recline one of the front seats, for the best sleeping position, if you have reflective sun shades, use them, they will help insulate the car’s interior.

Don’t be tempted to sleep with the engine running for heat, this is dangerous as exhaust gasses can easily find their way into the interior and cause a fatality.

Do you need to crack the window when sleeping in the car?

No. There will be sufficient air inside the car to prevent CO2 build-up, plus cars are not airtight even with the doors and windows closed.

Should you need to get some extra heat then you may want to run the engine, don’t do this. If you crack the window, the heat will just flow outside.

Running an engine while sleeping is dangerous.

How do you warm up a sleeping bag?

Keep your sleeping bag clean and wash it if needed. Sleeping bags lose their thermal properties when they become dirty, as the insulation flattens.

Here are a few tips to keep warm in your sleeping bag on a cold night:

  • Eat a heavy meal that is high in carbs, this will generate heat from your core and keep you warm for hours
  • Wear thermal socks and a thermal beanie hat, temperature loss is greatest through your head so keep it warm with a hat
  • Throw a hot water bottle in the sleeping bag, it should last for a considerable time and keep you warm for hours on end

Is 90 degrees too hot to sleep in?

You can manage. Sleeping in extreme temperatures if cold or hot is a challenge and both can end disastrously if you are not prepared.

For most of you, a sleeping temperature of around 65℉ is the sweet spot where you feel comfortable and can sleep with ease.

Bring this temperature up to 82℉ and it’s a whole new ball game, you can’t sleep with more than a bed sheet, you may need a fan for air movement.

However, if you plan ahead and keep hydrated, you can sleep in 90℉ safely.

Can sleeping in the heat make you sick?

Yes. Sleeping outdoors when it’s hot can be a challenge not only with the heat but the bugs that hang out on hot evenings.

Sleeping in the heat will dehydrate you so you will need to re-hydrate through the night to avoid waking with a headache.

It’s common to wake with a dry mouth in extreme heat and it’s possible to get some symptoms of heat stroke.

How do you know if you’re having a heat stroke?

If you are alone you may not know. Heat stroke occurs when your core body temperature is 104℉ or higher, the temperature should be taken rectally for an accurate reading.

You may exhibit some of the following symptoms:

  • You have stopped sweating and may feel as if you have the chills
  • You can lose your cognitive abilities and not be able to think rationally
  • Your speech can become slurred and unintelligible
  • You become confused
  • Irritability
  • You may become delirious and hallucinate
  • You can have a seizure grand or petit mall
  • Coma

You should not underestimate heatstroke and if you show symptoms get to an emergency facility pronto.

What’s the difference between heat stroke and heat exhaustion?

The severity of symptoms. Both are dangerous and present with similar symptoms. Vomiting and nausea may be fainting.

Heat stroke is defined by body temperature.

How do you sleep outside when it’s super hot?

Keep hydrated. It’s important to keep physical activities restricted when it’s hot, and you are sleeping outside.

Because you will become naturally dehydrated, avoid alcohol to prevent becoming dehydrated faster.

Eat a light evening meal such as salads with a small amount of protein. Eating a large meal will make you sleep hot.

Sleep under the fly sheet without your sleeping bag and allow a breeze to flow through if possible.

You can use damp compresses to remove some of the heat from your forehead. Sleep leather and rise early, the temperature will dip as you get into the early morning hours.

Which is best, sleeping in the cold or the heat?

They both have challenges. Sleeping in extreme temperatures can have dire consequences for those not prepared and experienced.
