Shishir Ritu (शिशिर ऋतु) - The Dewy/Frosty Season

Effects on Nature (Prakriti Prabhaav)

Effects on the Human Body (Sharira Prabhaav)

Dosha Status

• Vata dosha - accumulated and aggravated due to cold, dry, and rough environmental qualities
• Kapha dosha - begins to accumulate (sanchaya) due to cold and wetness; Kapha that built up in Hemant becomes further deposited
• Pitta dosha - vitiated Pitta from previous seasons gets pacified / specified during this time

Agni (Digestive Fire)

• Agni remains strong - just as in Hemant Ritu. The body's internal heat is high to counter external cold. This means digestion is powerful and the body can handle heavier foods.
• The body actively retains internal heat to maintain core temperature.

Bala (Physical Strength)

• Strength is at its highest grade during Shishir Ritu - it is the peak of physical vitality in the Ayurvedic calendar, continuing from the strength built in Hemant.
• Immunity is strong but begins to wane toward the season's end as Aadaan Kaal progresses.

Skin and Tissues

• Increased dryness (Rukshata) in skin, lips, hair, and joints due to Vata aggravation
• Skin can crack, flake, and become rough
• Joints may feel stiff and achy, especially in the morning
• Muscles and tendons become less flexible

Respiratory System

• Cold, dry air irritates the respiratory mucosa
• Kapha accumulation can cause increased mucus, nasal congestion, and heaviness in the chest
• Risk of colds, cough, and sinusitis increases - particularly toward the end of the season when Kapha starts to liquefy

Nervous System

• Vata increase can cause restlessness, anxiety, disturbed sleep, and mental dryness
• People may feel more scattered, forgetful, or fatigued mentally

Urinary System

• Cold weather increases urinary frequency (body loses less heat through sweating)

Recommended Ritucharya (Seasonal Regimen) for Shishir

Diet (Ahara)

• Heavy, oily, warm, and nourishing foods - milk, ghee, sesame (Tila), jaggery, wheat, urad dal
• Sweet, sour, and salty tastes (Madhura, Amla, Lavana Rasa) to counter dryness
• Warm ginger tea, herbal decoctions, and hot water
• Fermented preparations (fermentation generates warmth)
• Garlic (Lashuna), ginger (Sunthi), long pepper (Pippali), fenugreek, Haritaki
• Meat preparations (for non-vegetarians), bone broths

• Cold drinks and cold foods
• Vata-aggravating foods: dry, light, raw, and cold items (e.g., puffed rice, Bengal gram/Chana)
• Bitter and astringent tastes in excess (already dominant in the environment)

Lifestyle (Vihara)

• Warm baths and steam baths (Swedan) to counter cold and pacify Vata
• Oil massage (Abhyanga) daily, especially with sesame oil - generates heat, lubricates joints, pacifies Vata
• Head massage is specifically recommended
• Wear warm, heavy clothing - wool, silk, leather, thick cotton
• Live in warm, sheltered spaces; avoid exposure to cold wind
• Regular exercise is beneficial as Agni is strong
• Avoid day sleeping (increases Kapha)
• Sexual activity is considered appropriate in this season (bala/strength is high)

Panchakarma Consideration

• Moving into the next season (Vasant/Spring), Kapha that accumulated throughout Shishir should be expelled through Vamana (therapeutic emesis) and Nasya (nasal medication) to prevent Kapha-related disease.

Common Diseases in Shishir Ritu

• Colds, cough, rhinitis, sinusitis, bronchitis
• Dry skin, eczema, cracked heels
• Joint pain, arthritis flares
• Constipation (Vata in the colon)
• Headaches (from Vata)
• Stiffness and body ache
