The type of exercise that is best for the brain is aerobic exercise including walking, swimming, cycling, using a treadmill, resistance training and also doing mind body exercises.
Mind body practices like tai chi and yoga can help to enhance your brain health through focus on balance and mental clarity.
Running, cycling and brisk walking are all good for keeping your brain healthy.
Also doing tasks such as solving problems including solving math problems, doing puzzles etc can all keep the mind healthy and active and keep your memory in shape.
To increase blood flow to the brain while sleeping, adjust your sleeping position by sleeping on your side or sleep with your head and your legs elevated to reduce the pressure on your body.
Also ensuring you have optimal sleep conditions, like a dark, quite and cool room for sleeping also supports healthy brain function and blood flow at night or when sleeping.
Sleeping on your left side or your right side can help to alleviate pressure and improve the movement of blood and cerebrospinal fluid through your brain and raising your legs slightly higher than your head, by using a pillow or a wedge can also use the gravity to help blood flow from your lower body to the upper body and your brain.
You can increase the blood flow to the brain by exercising regularly, especially through moderate aerobic or interval training and also incorporate foods in your diet that are rich in Omega-3- fatty acids, like oily fish as well as nitrates such as beets into your diet.
Also staying hydrated and drinking enough water and managing high blood pressure and limiting your intake of unhealthy fats can also help improve blood flow and circulation to your brain.
Engaging in moderate intensity aerobic activities like brisk walking or swimming can improve your circulation and reduce your risk of arterial plaque.
Coffee can also increase blood flow to the brain.
The caffeine in coffee is a stimulant and works by blocking the adenosine receptors in your brain.
The blockage of the adenosine receptors in the brain due to the caffeine in coffee, leads to the release of neurotransmitters, which among other things dilate blood vessels in your brain.
Caffeine in coffee can increase cerebral blood flow by up to 30 percent and the increased blood flow can also improve alertness, cognitive function and reaction time.
Although the effect of caffeine on cerebral blood flow can also vary depending on the dose, your individual caffeine tolerance and the time of day.
And high doses of caffeine might actually decrease blood flow to the brain in some cases.
