All of us feel happy at different times and for different reasons.
We feel happy when we eat our favourite food made from grains, pulses and vegetables.
We feel happy when we play games with friends.
We feel happy when we spend time with our family.
We feel happy when we celebrate festivals and special moments. 
Being happy is an important part of being healthy. This unit helps us understand how food, exercise, rest and safety work together to keep us happy and healthy.
Have you ever wondered how food like rice or wheat reaches your plate? The journey of a grain from the farm to our plate is long and full of effort.
Many people and natural elements work together to make this possible. 
The hard work of farmers, the help of animals, and the support of shopkeepers and family members all matter.
Natural things like water, soil and sunlight are needed to grow grains.
Shopkeepers sell the grains and family members cook them for us. 
Did you know?
In India, we celebrate many festivals to show gratitude to Mother Nature for the food we eat. Examples are Makar Sankranti, Onam, Lohri and others.
Mindful eating means paying full attention to what we eat and how we eat it.
Once, a teacher asked students to sit in a circle and close their eyes. She placed one peanut in each child's hand and asked them to notice everything about it. 
The students followed these steps carefully:
Slowly put the peanut in the mouth and chew slowly.
Use the tongue to feel its surface.
Gently use the teeth to break it into pieces.
Use the tongue, nose and other senses to feel the taste.
Notice the texture (how the food feels) before swallowing.
The tongue helps us feel texture and move food around in the mouth.
The teeth break food into small pieces by chewing.
Food mixes with saliva, which makes it soft and easier to swallow. 
It helps us enjoy our food more.
We make healthier choices when we eat slowly.
It teaches us to be thankful for every bite. 
Next time you eat, try to chew slowly, enjoy the flavour, and be grateful for your food.
Every grain is important because many people and animals work hard to provide food for us.
Wasting food disrespects their efforts.
When we waste food, we forget the hard work that brought it to our plate. 
Remembering everyone who helps makes us enjoy each grain more.
Activity: For one week, keep a record of what you eat for breakfast, lunch and dinner and whether you finish your food or not.
Along with good food, it is important to exercise regularly to keep our bodies healthy.
Playing in open fields, running, cycling, skipping and other games make us strong and energetic.
Other activities like yoga help improve our posture and keep us active and happy.
The textbook Khel Yoga gives many fun exercises and games for physical education and well-being. 
Sleep is essential for staying fresh and full of energy.
Our body needs enough sleep each day to work well.
Good sleep removes tiredness and helps us feel refreshed. 
Lack of sleep makes it hard to concentrate on work or play. Getting enough sleep is as important as eating well and exercising.
Feeling safe helps us stay happy and healthy.
A safe touch feels like a comfortable hug from family.
An unsafe touch can make you feel uneasy or scared.
It can come from anyone - someone you know or a stranger. If you feel unsafe, say "No" and tell a trusted adult.
It is always okay to speak up - you should not feel guilty about it.
