Overlevelse is a compilation of several mods - Capming, Hypothermia and Total Realism - Basic Needs (all of which are on Nexus) with my own additions and configs thrown in to make the mod work automatically with no additional tweaks from you.
You can monitor the state of the character through the magic menu at the "Active Effects" tab.


Hypothermia:

Body cooling affects your combat skills, speed, and motor skills. The level of cooling depends on the region in which you are located.You can warm up in different ways - drink warming drinks, warm yourself by the fire and wear warm clothes.There are no indicators of warmth and moisture (as, for example, in the Frostfall mod), for greater immersion. You should intuitively understand which clothes will be warmer. Clothes with fur, leather and covered body parts are warmer than clothes made of metals and exposed body parts.

Needs and Deseases:

All food is labeled with text that you can use to determine the nutritional level. Dishes are divided into light and hearty. Products also tend to spoil. This process happens automatically, after eating spoiled food you get poisoned.

In addition to food, it is important to monitor thirst and water levels in the body. You can drink water, alcohol, or eat fresh fruit to replenish your body's water reserves. You can find empty bottles anywhere, or they will automatically appear in your inventory after you drink something, such as wine.

You should sleep every day, a sufficient number of hours, because every day we fight, chop firewood or travel long distances. Therefore, sleep should be regular and not less than 8 hours a day. Otherwise, you will receive negative effects and debuffs.

Diseases became more severe, more noticeable for the body and more frequent. You can become infected from animal bites, vampire and werewolf strikes, or from eating spoiled food and impure water.

Camping:

On a tanning rack, you can sew yourself a small tent, a sleeping bag or a double tent, and much more.
