- Reduced sweating: People who live in deserts have fewer sweat glands than those who live in cooler climates. This helps them to conserve water, as sweating is a major way that humans lose water from the body.
- Concentrated urine: People who live in deserts produce more concentrated urine than those who live in cooler climates. This also helps them to conserve water, as concentrated urine contains less water than dilute urine.
- Increased ability to store body fat: People who live in deserts have an increased ability to store body fat. This fat can be used for energy when food is scarce.
- Darker skin: People who live in deserts have darker skin than those who live in cooler climates. Darker skin helps to protect the skin from the sun's ultraviolet radiation, which can cause skin damage and cancer.
- Large eyes: People who live in deserts have large eyes that are adapted to low-light conditions. This helps them to see in the dark, when temperatures are cooler and it is easier to hunt and forage for food.
- Long limbs: People who live in deserts have long limbs that help them to dissipate heat. This is because heat is lost from the body more quickly through the extremities, such as the arms and legs.
- Thick skin: People who live in deserts have thick skin that helps them to protect their bodies from the sun, heat, and sand.
- Flattened nostrils: People who live in deserts have flattened nostrils that help to prevent sand from entering the nose during sandstorms.
- Cultural adaptations: People who live in deserts have also developed a number of cultural adaptations that help them to survive. For example, they may wear loose, lightweight clothing that helps them to stay cool, and they may live in homes made of materials that help to insulate them from the heat.
