ChronoPrakriti exercise

Our diet, exercise and sleep-wake pattern are three important factors regulating biological clock which are also mentioned in Ayurved as Ahar, Vihar and Nidra respectively. We already had discussion on ahar and nidra. Today we will talk about vihar that is role of exercise in tuning of chronoprakriti. Light is the primary external signal for tuning of central biological clock present in the brain. But the peripheral clocks present in various organs are setting their rhythms primarily by food and exercise and not by light.

When people think about exercise, they usually think in terms of building muscle or losing weight as though it’s a punishment for bad eating habits. It is much more than that which has effect on your body beyond fat burning or muscle building. We all need exercise every day but we don’t need the same amount or the same level of exertion. The time and pattern of exercise differs depending upon your body type. Body does not understand whether it is a formal or informal exercise regimen. Any kind of movement, including a single step will be considered as exercise by the body.

The Sanskrit word for exercise is vyayama which means improving circulation and communication through specific movements. The body is considered as an interconnecting channels. Over the course of a single day, these channels get sticky or blocked due to metabolic activities. These blockages can be removed by vital energy which we get from deep breathing. Exercise is essentially to pump the vital energy through all the channels by deep breathing. It is a kind of cleansing mechanism.

Altered circadian rhythmicity in skeletal muscle is a cause of concern in our sedentary lifestyle. This impacts reduced glucose tolerance and changes in mus­cle functioning and composition. These have a significant correlation with conditions such as diabetes, cardiovas­cular disease, and cancer. Hormonal regulation and resynchronization of the circadian clock as a result of aerobic exercise have each been linked to improved sleep quality, lower heart rate, and lower blood pressure. Skeletal muscle and bone have roles in not only the regulation of locomotion and postural support but also the control of nutritional homeostasis, such as maintaining glucose and calcium levels.

The phase of expression of many rhythmic genes in skeletal muscle occurs at the mid-point of the subjective active phase. Scheduled exercise can entrain the circadian clocks in skeletal muscles i.e. the phase of rhythmic gene expression in skeletal muscle may be regulated by the rhythm of locomotor activity. Individual sleep patterns can also impact the optimal timing of exercise. Sleep duration and onset time depend on the chronoprakriti type.

In our urban lifestyle, we are indoors for most of the time and even prefer gym schedule in the evening after hectic daily activities as a mean for relaxation. Morning outdoor activity is essential for our body which gives strong signal that the day has started and sets the circadian rhythm necessary for regulating sleep-wake pattern. Additionally when you exercise before first meal of the day, less sugar is available in the circulation and body is forced to tap into fat reserves. Late evening intense exercise on the other hand make you alert and overheated for the sleep by suppressing the melatonin secretion. It confuses the body’s circadian rhythm and interferes in sleep-wake cycle.

It is hard for most of the people to start and stick to an exercise routine. The trick is to introduce variation and not worrying about amount of exercise. It may be less than the previous day but performed at the same time. Moderation is the key in anything you do for sustainable goals and exercise is no exception to it. We will talk separately about sports chronobiology where you need intense workouts for specific goals but for average individual variety of exercise regimen which allows deep breathing is sufficient for tuning of muscle clock.

All professionals directly or indirectly involved in health or wellness do concerned with the change in eating habits or lack of exercise or importance of sleep and recommend you healthy habits so as to handle lifestyle disorders. But have you heard anyone talking about internal clock? Very few of them are even aware about it. They will tell you what to do or what not to do, similarly how to do or how not to do. But none of them emphasis on when to do or when not do.

If my body requires certain amount of calories, I may eat at any time of day and fulfil the requirement. If my body requires certain amount of exercise, I can do it even just before going to bed. If I am short of sleep hours during weekdays, I may recover it by sleeping more on weekends! All these practices making us more vulnerable for lifestyle disorders and all of us are blissfully unaware about it.

Whatever we do in our daily schedule, it has to be aimed at tuning our internal clock. The clock is the natural mechanism to prepare the body for specific task, may be it is mental or physical. Frequent change in time in routine activities confuses the inner mechanism and body has to spend excess energy to compensate the change. For example, you are sleeping two hours late on every weekend as compared to weekday is nothing but a kind of jet lag your body is experiencing and all of us are aware about body response when we travel to different time zone.

This internal clock though dependent on diet, exercise and sleep, does not work same for all individuals. The external manifestation of inner clock is the natural preferences for given activity or variation in peak performance time. Some people may be comfortable in working earlier part of the day and some other may be later part of the day. For such tendencies we call morning person or evening person in lay man’s term to which the technical term is chronotype. Ayurved too insists on personalized medicine based on the prakriti types. These types are nothing but a variation in inner clock mechanism. Hence we are combining the two body types so as to assess the chronoprakriti of an individual.

Let’s talk about exercise regimen according to your chronoprakriti. Based on whether you are morning or evening person, your muscle coordination will vary. Irrespective of that, morning exercise in natural settings is recommended for all which will send strong signal to brain about the start of day. If you are looking for specific weight gain or loss or muscle building through exercise, then along with morning workout, you need to follow additional work out regimens which will be based on your chronoprakriti type.

According to seasons, doshas show three types of response – 1) Accumulation of dosha 2) Aggravation of dosha and 3) Decrease of dosha. As per the season and your prevalent prakriti condition we need to select the type of exercise. Vata people benefit from slow and steady strength training, Pitta people need training to calm and cool down whereas Kapha people benefited by heated sweaty sessions. Based on the season and your dosha type you need to vary the type of exercise.

The exercise regimen may change as you age. The body requirements will be different depending upon your profession. Similarly women may require different set of body movements as those of men. All these considerations will make your personalized exercise format which will tune the muscle clock. The clock present in the skeletal muscles retains its rhythmicity by scheduled body movements. And this peripheral clock is not merely responsible for regulation of locomotion and postural support but also the control of nutritional homeostasis, such as maintaining glucose and calcium levels.

How much exercise do I need? This is a tough question. My personal opinion is unless you are very much keen in muscle building or getting train for specific sports activity that does not matter. The time and type of exercise matter more than the amount of exercise to tune your internal clock. The take home message is regular exercise is as necessary as your diet and both together will help you to tune your peripheral clocks. I will recommend to find out your chronoprakriti from our website for getting personalized recommendations for your peak performance period.

ChronoPrakriti Light

Our diet, exercise and sleep-wake pattern are three important factors regulating biological clock which are also mentioned in Ayurved as Ahar, Vihar and Nidra respectively. Today we will talk about sleep wake pattern or effect of light.

Light is the major external signal that sets our internal clock. The solar 24-hour cycle has existed for more than 4 billion years, and it has led to the evolution of circadian rhythms in most organisms. Environmental light is the strongest synchronizer for the circadian system, and phase-resetting capacities to light mainly depend on time of day, light intensity, and spectral composition. We spend most of the time in artificial light either at home or at office which has light intensity in the range of 300 – 500 lux whereas the day light intensity during clear sky is between 50,000 – 1,00,000 lux. Light exerts acute effects on subjective alertness and cognitive performance, and it inhibits the secretion of melatonin or sleep hormone by the pineal gland.

Acute light effects are dependent on the photo-pigment melanopsin which is present in the retina of eye and are stronger when light contains a greater proportion of blue light. Limited exposure to sufficient natural light disturbs the natural rhythm of melatonin and cortisol secretion which affects our majority of the bodily activities.

Chronobiological knowledge of how light affects human behavior has begun to be implemented at work places, in schools and in clinical environments. There are still strong experimental evidences required to test, predict and apply optimal lighting conditions for different populations and patients, in terms of spectral composition, light intensity, and dynamics. Also, geographical latitude, building exposure, and building properties play an important role.

Artificial light sources are widely used in our everyday lives to illuminate streets and our homes. There has been a change to use more energy efficient technologies such as light emitting diodes (LEDs) and an increase in the use of digital screens. Artificial lights can vary widely in their brightness and colour composition, including how much blue light they emit. These properties, together with the timing and duration of their use, can alter how these light sources may affect health and the environment.

Despite the multitude of studies investigating light effects on humans, it is still unclear how much light is needed during daytime to stay fully entrained to the environmental light-dark cycle. This becomes an important topic in our round-the-clock society, since the time we spend outside during the day progressively decreases, whereas the time we spend with light-emitting devices during the night increases.

Humans have evolved to use daylight and darkness to regulate circadian rhythms, which is important for our health and wellbeing. Increasing exposure to natural daylight, particularly in the morning, can help synchronise the body clock with the solar day. Limiting the amount of light at night is also important for circadian health.

Advances in lighting technology have provided possible ways of reducing adverse lighting effects and enhancing other desired effects. Compared with earlier lighting technologies, LEDs provide precise optical control and more opportunity to change and tune their spectral distribution, allowing lighting designers to reduce obtrusive effects from light scattering into unintended areas.

Effect of light on our body is dependent on the Ayurvedic dosha which constitute your Prakriti. Doshas vary during 24 hours cycle and finding out individual Prakriti would be beneficial to understand the sleep wake pattern. Vata people has superficial sleep and can be disturbed easily as compared to Kapha people who spend more time in deep Non-REM sleep as compared to two other types of Prakriti. Pitta people are also light sleepers but can fall back asleep easily if disturbed during the sleep. Sleep requirements may vary based on your Prakriti type along with other parameters.

I will recommend to find out your chronoprakriti from our website and maintain a sleep diary for a least one week to follow your sleep wake pattern.

ChronoPrakriti Diet

Our diet, exercise and sleep-wake pattern are three important factors regulating biological clock which are also mentioned in Ayurved as Ahar, Vihar and Nidra respectively. Today we will talk about diet or Ahar. There are various diet plans available in the market and we try them randomly which may work in the beginning or may work only for certain duration only. I am going to tell you about the Chronoprakriti diet plan which is not just another diet plan but altogether different approach of weight management.

Here, I am going to tell you the basis of diet regimen which is not focusing on how many calories to eat but more concerned about when to eat those required calories. If you ask any dietician or physician about Chronoprakriti diet plan they will simply reject it out of ignorance. Even though a lay person is aware about importance of doing thing at appropriate time, scientifically it is still not validated why an appropriate time of doing everything matters.

Fortunately, experimental data is also coming up to support this age old notion of doing right things at right time. A laboratory mice feed with high calorie diet during night time is not gaining weight but become obese if it is provided during the day time. As mice is a nocturnal animal, night time is the natural activity time and food intake during activity time is not adding any fat deposition. If we take clue from this experiment then we can understand that for humans, day time calorie intake associated with physical activity will not add any weight gain.

Chronoprakriti diet recommends to have 5 hours gap between two day time meals and 12 hours gap between dinner and breakfast. There should not be any snacking in between and only water may be allowed during the gap. This five hours gap will ensure that the metabolic clock will be synchronized to their daily rhythm and 12 hours gap will ensure that the gut microbiome will be sufficiently rested and rejuvenated for next cycle. This three meal pattern at consistent time of the day is recommended to tune your chronoprakriti.

Chronoprakriti diet plan will become personalized based on your chronoprakriti assessment. Your prakriti will decide which type of food you should prefer or avoid depending upon your age, season, geographical location and prevalent health condition. Your chronotype will decide whether you should have large breakfast or large lunch or large dinner.

Seasonal and local food products induces changes in the metabolism due to the particular phenolic profile that the product contains hence the Chronoprakriti diet insists on seasonal and local variety of food products in your diet.

Even though we stick to this diet plan for weekdays and change it for weekends then body will experience what is called ‘metabolic jet lag’ Even without travelling to different time zone, your gut microbiome will experience the change in food intake that will disturb their rhythm and it will be take time to regain it.

So we should have consistent food timing on all days as much as possible. If it happens that due to social obligations, there is a change in meal pattern, it is recommended to fast next day to readjust the metabolic clock. Weekly fasting is highly recommended to keep your metabolic clock healthy.

Our body is not made for 24x7 food intake. Due to availability of processed food round the clock our eating window is almost equivalent to our waking hours and that is creating all types of health issues. Our aim should be finishing a food intake in specific time span which should be less than 12 hours. If we could keep our digestive tract empty for at least 13-14 hrs then our peripheral clocks can tune themselves easily and help process excess nutrients properly by the body.
