7 Tips for Having a Healthy Life and a Healthy Mind
Leading busy lives, many people sometimes overlook how to run a healthy life that can affect the mind positively and directly. If youβre looking for ways on how to do better when it comes to improving your health, mind and life, you can check out the following for some tips to achieve this goal.
1. Sleep well
A good night of sleep daily is equal to good health and for reasons. Sleeping can make you energetic and alert and feel better. A quality sleep also leads to better concentration and focus to finish your daily tasks.
For this reason, you should aim to get sufficient sleepto improve your biological function and body functions, including brain development and physical repair and recovery.
Sleeping well also reduces stress levels and keeps it under control, lowering your risk of chronic diseases related to it, such as high blood pressure anddiabetes.
With proper sleep, you also improve your appetite and reduce chances of stress eating. So if you want to avoid the risk of becoming overweight, take full hours of sleep.
2. Spend quality time with loved ones and friends
Enjoying some laughs with friends and loved ones does not just make you happy but also healthy. It can make you feel better, reducing stress levels, and help you live a more satisfying life.
Spending time with loved ones and friends do not just also give you a balanced life but one filled with happiness. And by having fun and lighthearted moments on a daily basis, youβre able to deal with tough challenges because you maintain positive emotions.
Social interaction and spending time with othersmay also lengthen your life because having a good relationship with loved ones and friends also contribute to positive health effects. Importantly, it also improves your psychological well-being because of the emotional support that social ties bring into your life.
3. Develop yourself in the fields of the soul
If there is food for the brain and the body, there is also food for the soul. Nourishing and developing yourself in the fields of the soul can lead to a more fulfilling life.
Being spiritually healthy, you can step out of the body and mind and connect with your truest self, one of the keys to happiness. You should desire to grow spiritually, and a few practices include meditation, prayer, stillness, pondering, mindfulness and yoga.
4. Take care of both physical & mental
Looking after both these aspects, youβll live a healthy life and have a healthy mind. To take care of your mental health, you should train your brain, which is like a muscle that needs constant exercise; otherwise, it will decline in function and lose its tone. In addition, you should take care of your physical health to prevent disease and live a more productivelife.
A few ways to take care of physical and mental health include exercising regularly, reading widely and often, boosting your vitamin B levels and challenging your memory and intellect. Time for relaxation is also a good way of taking care of your mental and physical health because it lowers cortisol or stress hormone levels.
5. Donβt let small βflawsβ ruin your life
Your attitude is everything because how you perceive and explain your world affects your life. Never let small flaws such as moles, uneven skin tone, large waistline, stuttering or speech issues, among others, ruin it.
If you want to achieve real happiness and live a healthy mind and body, you should not let your flaws put you down, but look for solutions to fix them.
For example, have a private speech therapyif you have stuttering or speech problems. This therapy will help you achieve fluent speech, better life quality and greater self-esteem. By being able to express yourself fluently, you will notice an improvement on your self-esteem and confidence.

6. Take enjoyable activities
One of the best ways to achieve a healthy mind and body is to engage in enjoyable activities that do not only keep you engage mentally and physically but also up your mood and self-esteem.
For one, you should not stop challenging your brain to make it more powerful, according to certain studies. You should not also be afraid to try things, such as a new hobby, or volunteering, which can make you more social. Alternatively, you can try finding something that you are passionate about and do it.
7. Be thankful
Gratitude cannot be stressed enough regarding its benefit for the body and the brain. For mental health, being thankfulcan boost the brainβs supply of dopamine, which can give you a natural high.
With this increased motivation, youβre able to get more of life because youβd have the vigor and always feel good about yourself and the world aroundyou.
Being thankful also leads to a better sleep and decreased pain levels, improving your energy to do exercise and all the things you love.
Are you ready to run a healthy life and have a healthymind?
Keep these tips in mind β be thankful, spend time with friends and loved ones and take enjoyable activities, to name some, and notice the big difference on how more fulfilling life becomes.

π°Activated sludge process (ASP)
πΆActivated sludge:-
It is sludge containing large concentration of highly active aerobic micro organisms.
πΈASP works on the principle of suspended culture system.
πΈComponents of ASP
A) Primary settling tank :-
~ Detention time - 1.5 to 2 hr.
B) Aeration tank :-
~ Detention time- 4 to 8 hr
C) Secondary sedimentation tank :-
~ Detention time- 1.5 to 2 hr.
D) Sludge thickener & sludge digestion tank
πΈActivated sludge process parameters
1.Hydraulic retention time (HRT):- It is the ratio of volume of tank to the rate of sewage flow into the tank.
2.Volumetric loading rate or BOD loading rate:- It is ratio of BOD applied to unit volume of aeration tank.
3. Food to microorganism ratio (F/M):- It is defined as the ratio of kg of BOD applied per day to kg of MLSS in aeration tank.
4.Mean cell residence time (Sludge age):- It is defined as mass of cell in the reactors to mass of cells wasted per day.
5.Sludge volume index:-
It is the volume occupied in ml by 1 gm MLSS after settling for 30 minute from 1L sewage sample is known as sludge volume index.
πΈUsual values adpoted
π F/M :- 0.4 to 0.3
π MCRT :- 5 to 15 days
π Efficiency :- 85 - 95%
π Recycling ratio :- 0.25 - 0.5
πΈ Operational problems associated with ASP
1. Rising of sludge :- Settled sludge contains large number of live cells. They oxidise the dead cells and release nitrogen. The nitrogen causes the sludge to risep and increases the Xe value.
~ Remedies :- Increase Qr & Decrease Q
2. Bulking of sludge :- Large number of dead cell in settled sludge and growth of filamentous organisms. Occurs when SVI β 150
~ Remedies :- Bring down SVI (β 150), Increase pH, Increase DO, decrease F/M ratio.
