8 Best Rated Indoor Outdoor Thermometers of 2022 – Unbiased Reviews

O utdoor thermometers help you keep tabs on the weather so you can determine the trend and make plans for the future. On the other hand, indoor models enable you to monitor the ambiance so you will know whether you need to turn down the heat or not. But what if you could get a device that monitors both the indoor and outdoor temp so you can check both with a single glance? Luckily, the market has a generous offer of heat meters for the interior and exterior, some enhanced with other details like humidity or time and date.

Based on sensors that collect weather data, these compact yet smart devices let you monitor and control the environment inside your house and outside it. We selected the most reliable ones, so you will be able to pick from the ones that are worth taking into account. Check them out in the following.

What Is the Healthiest Indoor Temperature?

Deciding at what temperature you should set the thermostat can be a big headache, especially if you don’t live alone. Aside from the fact that you have to factor in how everyone prefers the temperature, there are also cost considerations to take into account because, let’s face it, keeping the house warm in winter and cooler during summer isn’t cheap. However, no matter what costs are involved, you must make sure that the temperature is within healthy parameters for your body, or there will be consequences.

When your crib is cold, your whole body starts trembling and you are one step closer to catching a nasty cold. A study regarding the relation between indoor temperature and health shows that high temperatures aren’t any better either, “respiratory health, diabetes management and core schizophrenia and dementia symptoms” being affected in the process.

The question inevitably arises – what temperature should you try to maintain indoors? Use your trusty thermometer and, depending on the season, put the AC or heater to good use and try to aim for a temperature from 18 to 24 degrees Celsius or 64 to 75 degrees Fahrenheit as suggested by the World Health Organization. As long as the thermometer is displaying stats within the aforementioned range, you can rest assured knowing that your comfort and health aren’t at stake since there is thermal balance indoors.
