What is the minimum amount of water an average adult should drink daily?

Back

8-10 cups

Answer explanation

FUN FACT :

By the time you feel thirsty, you've already lost about 2-3% of your body's water content. This means that thirst isn't actually the first sign of dehydration - it's a sign that you're already dehydrated! This is why medical experts recommend drinking water regularly throughout the day, even before you feel thirsty. Your body loses water through breathing alone - you exhale between 2-4 cups of water vapor every day just through normal breathing.

What is the recommended amount of sleep for adults per night?
Options: 5-6 hours, 6-7 hours, 7-9 hours, 9-11 hours

Back

7-9 hours

Answer explanation

FUN FACT:

Missing just 1-2 hours of sleep for even one night affects your brain similarly to drinking 2-3 beers - your reaction times, judgment, and cognitive performance all become significantly impaired. This is why driving while sleep-deprived can be as dangerous as driving under the influence. After 18 hours without sleep, your cognitive impairment is equivalent to having a blood alcohol content (BAC) of 0.05%, and after 24 hours without sleep, it's equivalent to a BAC of 0.10% - which is above the legal driving limit in most countries!

How many minutes of mindfulness meditation per day can help reduce stress?
Options: 5 minutes, 10 minutes, 20 minutes, 30 minutes

Back

5 minutes

Answer explanation

FUN FACT:

Research has shown that regular mindfulness practice can actually change the physical structure of your brain in as little as 8 weeks. Specifically, it can increase the density of gray matter in areas associated with learning, memory, and emotional regulation, while reducing the size of the amygdala, which is responsible for fear and stress responses. This process is known as neuroplasticity, and it demonstrates how our mental practices can literally reshape our brains!

What percentage of our dreams are negative or anxiety-inducing?

Back

65%

Answer explanation

FUN FACT:

People who sleep on their backs (supine position) are more likely to experience anxiety dreams and nightmares than those who sleep in other positions. Scientists believe this might be because sleeping on your back can cause minor breathing difficulties, which your brain might incorporate into your dreams as stressful situations.

How often should you take breaks from sitting during work?

Back

Every 30 minutes

Answer explanation

FUN FACT:

Brief periods of "unfocus" (like during breaks) actually activate a different neural circuit called the "default mode network," which is crucial for creativity and problem-solving.

Standing up and walking for just 2 minutes every hour can offset some of the negative health effects of sitting all day.
