Feeling Stressed? Cardiologist Suggests This Simple Brain-Calming Routine

In today’s fast paced lifestyle, anxiety, mental exhaustion, and constant screen exposure can leave the brain drained and fatigued. While several individuals rely on caffeine boost to stay active and productive, leading cardiologist & functional medicine expert with 40-years of experience, Dr Alok Chopra suggests that an “afternoon nap of just 20 minutes can help you brains shift out of stress into repair, clarity, and integration.”

Earlier, experts also suggested that a short 20 minutes afternoon nap can naturally help the brain recover, recharge, and function better. Short daytime naps can support memory, improve concentration, and enhance mental clarity.  

According to a Study featured in National Library of Medicine, “Naps (brief sleeps) are a global and highly prevalent phenomenon, thus warranting consideration for their effects on cognitive functioning. Naps can reduce sleepiness and improve cognitive performance. The benefits of brief (5-15 min) naps are almost immediate after the nap and last a limited period (1-3h). Longer naps (> 30 min) can produce impairment from sleep inertia for a short period after waking but then produce improved cognitive performance for a longer period (up to many hours).” ¹

How Stress Impacts Brain Health?  

Chronic stress can keep the brain under a constant state of alertness. Over a period of time, it may impact concentration, sleep quality, emotional health, and even decision-making abilities. Mental overload can also enhance exhaustion, irritation, and difficulty processing information.  A short nap may help break this anxiety cycle by proving the brain a short period of rest and recovery.  

How A 20-Minutes Nap Works?  

Experts frequently advise taking short 15-20 minutes nap. This period helps the body and brain relax without entering the deep sleep stages that may leave an individual feeling groggy later on.

Dr Alok Chopra said, “one of the most powerful things you can do for your brain is something most people feel guilty about an afternoon nap. But, I am not talking about long, lazy sleep. I am talking about a very specific phase called the Theta Rhythm Sleep. This is a unique state where you are asleep but still slightly awake. If someone calls your name, you might respond but your brain has already entered a deep restorative mode. ²

Around 2:30 in the afternoon, your body naturally dips into this rhythm. This is not a random, this is part of your body clock. If you take a 20 minutes nap at this time, your brain shifts out of stress into repair, clarity, and integration. Many times, you wake up with answers that you did not have before. And, many of my patients tell me, “Doctor Sahab, office me kaise karein? I tell them to kya ho gaya? Office mei to hota hi hai, just put your head down for 15-20 minutes. Reset yourself. You will work better after that, added Dr Chopra.

“I will tell you something interesting. In my appointment diary, every single day around this time, there is a patient named Mr S.K. Khanna. Now people wonder – who is this very regular patient. Mr S.K. Khanna is actually my rest time partner,” joked Dr Chopra.  

How Short Nap May Help You?  

• Enhances Alertness

• Improves Concentration

It is worth noting that unlike long naps, a short nap can significantly rejuvenate the brain without impacting night time sleep for most individuals.  

Benefits of Afternoon Short Nap

Reduces Stress

During short nap, brain receives an opportunity to slow down and recover from constant stimulation. Short naps also reduce stress hormones and improve relaxation. The recovery period lets the brain process the information better and enhance mental integration. Short power naps may also support the nervous system by decreasing feelings of overwhelm and tiredness.  

Improves Memory & Clarity  

Short Naps may enhance memory retention and cognitive performance. Students and working professionals often feel more mentally clear and focused after a quick short nap.  

The brain uses rest periods to organise and process information collected throughout the day. This may help improve learning and productivity.

Best Time For Short Nap

The best time for a short afternoon nap is early to mid-afternoon between 1 pm to 3 pm. Napping too late in the evening may interfere with nighttime sleep.  

Tips for Better Napping

• Keep naps between 15–20 minutes

• Nap in a quiet and dim environment

• Avoid very long daytime naps

• Set an alarm to avoid oversleeping

• Maintain a regular sleep schedule at night

A simple 20-minute afternoon nap may help the brain shift from stress and fatigue into a more relaxed and refreshed state. By supporting mental clarity, focus, mood, and cognitive recovery, short naps can become a healthy addition to a balanced daily routine when practiced in moderation.
