Exercise helps new brain cells grow in the hippocampus, which is critical not only for memory but also for imagination and putting ideas together in new ways.

The fastest way to reduce stress is the physiological sigh: two inhales through the nose followed by a long exhale through the mouth to rapidly offload carbon dioxide.

Couples who manage to laugh during arguments report higher relationship satisfaction and show fewer physiological signs of stress, like cortisol.

Just 10 minutes of walking is the minimum amount of movement shown by science to cause significant decreases in anxiety levels and increases in positive mood.

A testable hypothesis in neuroscience is that increased awareness of mental health problems can sometimes make them worse by causing people to focus on and consolidate their symptoms.

The eye has a third photoreceptor that regulates the body clock and requires very bright light, around 50 to 100 times brighter than average domestic lighting.

Light from devices in the evening is more likely to delay sleep by increasing alertness rather than by significantly shifting your biological clock.

Most people's internal body clocks are slightly longer than 24 hours and naturally drift later, so morning light is essential to shove the clock forward and keep it aligned.

When your mind is racing, it is far more effective to use physical tools like breathing to control your mental state than it is to try and control your thoughts with thoughts.

Moving your body is like giving your brain a wonderful bubble bath of neurochemicals like dopamine and serotonin that make you feel good and bring your energy up.
