Heat is a negative status effect that saps your strength and increases your 
thirst. Energy and coordination are affected, and you will generally under perform while hot.
Mechanics
The in-game pop up gives a brief description about heat:
You're feeling too hot, which is hard on your energy level.
Natural shelters and water could help.
Heat isn't fatal but saps your energy and ability to coordinate your actions. It also speeds up the rate at which you get thirsty. Everything is tougher to complete when hot.
The longer that you expose your hominid to conditions that induce hyperthermia, the quicker that you will encounter the Heat status effect.
- Heat is first encountered during the daytime as soon as you enter the
Savanna, extends through the 
Canyon, and finally out into the 
Ocean. - Find a shelter that stops the sun beating down on you and heat will disappear. This isn't a single tree or bushes. You have to have substantial solid cover above your head to stop the sun so you can cool down.
Important: Your clan members may suffer from heat without you noticing, so keep an eye out for visual signs of discomfort!
Learning specific neurons reduces the negative effects of heat.
Stage 1
Stage 1 is found when you are exposed to hot conditions. You begin to breath hard and a light orange filter will cover the screen reducing vision. Travel is still possible at stage 1 and relatively easy.
Stage 2
Stage 2 is found when you continue to expose your hominid to hot conditions. You will be breathing harder even more, you will have difficulty completing tasks, and more energy is spent to complete those actions. The orange filter will get darker and cover more of the screen making it more difficult to see threats. Travel during stage 2 is possible but vision is reduced and it can be dangerous.
Remedies
Medicines able to stop the heat condition:
- Aloe Sap
- Fresh Water Source
- Mud
- Salt Water Source (but causes Food Poisoning)
- Stagnant Water Source (but causes Food Poisoning)
Heat Protection
Medicines can also be used before being afflicted with negative status effects to give positive status effects or "protections". These protections allow you to endure situations that would normally cause you harm.
Be aware that protections run on a timer and will eventually run out. The protections will also reduce by the amount of damage they stop. Your hominid won't be harmed but the protections will go down instead. You will need to add more protections over time to ensure you aren't going to be harmed by afflictions.
Medicines that confer heat protection:
- Aloe Sap
- Fresh Water Source
- Mud
- Salt Water Source (but causes Food Poisoning)
- Stagnant Water Source (but causes Food Poisoning)
Be aware that water sources will only give heat protection in areas where heat takes place.
Neurons
The following neurons impact heat.
